| Seven
Years to Saturn
Pasadena December
10, 2001 (NASA/JPL) - As if going to Saturn wasn't hard enough, deciding
what science to collect once in orbit around the giant planet is a
logistic maze.
Launched in 1997, the international mission Cassini-Huygens will take
almost seven years to reach the planet famed for those amazing rings that
puzzled generations of astronomers. To save fuel and to travel the huge
distance, more than 3 billion kilometers so far, the spacecraft used a
technique called gravity assist. It looped around Venus twice, then flew
past Earth and finally around Jupiter. The slingshot boost from these
passes will deliver the Cassini orbiter and its probe, Huygens, to Saturn
in July 2004. The probe will later descend to Titan, the biggest of some
30 known moons orbiting Saturn.
The Huygens probe will provide information on Titan, which has an
atmosphere that extends about 1,000 kilometers (620 miles) from the
surface. Because of its distance from the Sun, its surface is frozen and
its temperatures are extremely low. Compared to Earth, Titan receives only
one percent of the Sun's light.
Choosing what data to collect with the spacecraft's many instruments once
at Saturn is keeping scientists busy these days, as they are planning a
minute-by-minute timetable for the four-year mission. The challenge is
caused by the abundance of interesting science targets along the planned
74 orbits around Saturn, and the wealth of instruments onboard the
spacecraft.
"There is a
lot of intriguing science with Titan, the most Earth-like world out there,
and we want to know a lot more about Saturn," says Dr. Kevin Baines,
a planetary scientist at JPL involved with the science timetable.
"The rings are sitting there, shining away. They are mysterious and
we are going to look at those and also the icy satellites."
Logistic issues complicate the planning task.
One matter is downloading the information collected by the data recorder
on board. Once it is full, the spacecraft must turn toward Earth and begin
downloading the data. Because of the great distance, the signal takes
about an hour and 15 minutes to reach the Deep Space Network's antennas.
Downloading the data takes up to 9 hours. When Cassini is collecting data,
scientists have to make hard choices on which instrument to use. In order
to save money, Cassini's instruments are all fastened in fixed positions
and cannot be pointed independently of another.
"We have all these mutually exclusive desires," explains Baines.
"We have different targets and when we get to a particular target
there are a lot of different things we want to do. All the scientists
involved must collaborate with each other."
Eager to decode the many mysteries of Saturn and its moons, scientists are
painstakingly examining each of the 74 planned orbits around the planet,
trying to include as many unique and relevant observations as possible,
without compromising each other's instruments and goals.
The complicating factor is that of the 265 scientists involved with the
mission, only 125 live in the U.S. This translates in teleconferences
across 12 time zones, with scientists in Hawaii getting up early while
their colleagues in Europe are putting their kids to bed. Through tons of
emails, web charts and conference calls, scientists from 16 countries have
30 months to come up with an integrated time chart that will provide the
best plan to gather as much information as possible about the sixth planet
from the Sun, the second largest in our solar system.
Mission to Pluto
Edges Closer to 2006 Liftoff
By Peter N.
Spotts
EARTH December 10, 2001 (Christian Science Monitor) - Alan Stern hunts for
ancient relics.
No picks, shovels, or dusting brushes fill his tool kit, however. His lost
city of Troy is Pluto - the only planet in the solar system that a
spacecraft has yet to visit.
Little wonder then that when the National Aeronautics and Space
Administration recently hired his team to help flesh out its concept for a
mission to Pluto, Dr. Stern was delighted.
"It's the
dream of a lifetime," says Stern, lead scientist for the Pluto-Kuiper
Belt Mission, which he describes as "the first mission to the solar
system's last planet."
Since its discovery in 1930, Pluto has been "an enigmatic spit of an
ice ball" in the solar system's planetary line-up, says Stern,
director of the space-science program at the Southwest Research Institute
in Boulder, Colo. But Pluto's importance rose dramatically after 1992,
with the discovery of a belt of planet wannabes beyond Neptune called the
Kuiper Belt.
Pluto and its moon, Charon, are the largest objects in the Kuiper Belt
region, which scientists believe served as the nursery for fledgling
planets. In this area, planets still in the formation stages sometimes
smashed together in spectacular collisions, halting their
"normal" path of development. Indeed, says Stern, Pluto and
Charon are viewed as chunks of a larger planet whose growth ended when it
collided with another large body.
In Pluto and the Kuiper Belt, Stern says, "we have this equivalent of
an archaeological dig into the history of the solar system." It's the
"only place we have," he adds, that can give scientists a window
on that period of time.
Beyond Pluto's role as a planetary pot shard, its scientific allure stems
from the fact that so little is known about its basic physical
characteristics compared with the rest of the solar system's major bodies.
Charon was discovered only in 1978, allowing researchers to get a better
handle on the mass and density of the Pluto-Charon system.
Seen from Earth, Charon and Pluto appear to sometimes hide each other as
they orbit. By carefully tracking these disappearances and reappearances,
or occultation, astronomers have been able to map rough differences in
brightness across the faces of both bodies.
Using the Hubble Space Telescope and ground-based observatories,
"we're starting to get enough information to point to a particular
place on the surface and detect differences," says Marc Buie, an
astronomer at the Lowell Observatory in Flagstaff, Ariz., where Pluto was
discovered. For example, observations have pinpointed a spot on the
surface unusually rich in carbon-monoxide ice.
This could be a carbon-monoxide deposit bared by an impact crater, he
says, or the result of cryovulcanism - the frosty equivalent of volcanic
activity on Earth.
"What the heck is going on at the surface? There's no way of knowing
without a mission to the planet," he says.
As currently envisioned, the Pluto-Kuiper Belt mission would launch in
2006 and fly by Pluto and Charon before 2020. Timing is important, because
planetary alignments will be most favorable during this period for using
Jupiter's gravity to sling the spacecraft toward Pluto.
The timing also is urgent because Pluto is heading for the solar system's
outskirts. The planet's orbit traces an oval around the sun, and Pluto has
just finished its closest approach. Astronomers estimate that by 2020,
much of the planet's atmosphere will have frozen and fallen to the
surface, preventing scientists from getting a handle on Pluto's tenuous
envelope of gas and how it interacts with the solar wind, a stream of
charged particles constantly flowing from the sun.
"This is a very ambitious mission," acknowledges Colleen
Hartman, director of NASA's solar-system exploration division.
For all the scientific interest, the mission's finances may be as
ephemeral as Pluto's atmosphere. The project is funded only through the
end of the current $30 million mission-design study, a condition that Dr.
Hartman says "is very unusual for a planetary mission."
Until November 2000, CalTech's Jet Propulsion Laboratory (JPL) in Pasadena
spearheaded the project. But cost estimates ballooned to nearly $1
billion, threatening to become one of the Battlestar Galacticas that
former NASA administrator Daniel Goldin fought to ground in favor of
smaller, more frequent missions.
Last fall, NASA directed JPL to stop work on the project. When President
Bush submitted his fiscal 2002 budget, a mission to Pluto was nowhere to
be found.
But a trip to Pluto quickly became the people's mission. When the project
was canceled, Stern says, "a 19-year-old space buff set up a website
and triggered an avalanche of 10,000 letters to Congress in two weeks
flat."
Groups such as the Planetary Society, headquartered in Pasadena, threw
their weight behind a Pluto mission. When the smoke of budget battle
cleared, Congress had added $30 million to NASA's budget to keep a Pluto
mission alive.
But it's a one-year reprieve. The project's progress beyond blueprints
hinges on a favorable review of the design, regulatory approval to use
plutonium-driven generators for electrical power, and availability of
money.
If planners must go back to Capitol Hill, Stern says, they will be armed.
This week, a NASA planetary science advisory committee said that a Pluto
mission should be given the highest priority in NASA's planetary
exploration program.
"The space program been lacking the kind of first-time exploration
that was popular with Apollo, Voyager, and Viking," Stern says,
adding that the Pluto mission can fill that void.
The world
of Pluto
- One trip
around the sun takes Pluto 248 years; a season lasts 62 years.
- Pluto is
half the size of the second-smallest planet, Mercury. Pluto's
moon, Charon, is half the size of the planet.
- Pluto's
composition is unknown, but its density indicates that it is
probably a mixture of 70 percent rock and 30 percent water ice.
- Pluto and
Mercury are the only planets that have elliptical, not circular,
orbits.
- In Roman
mythology, Pluto is the god of the underworld. The planet got
its name - after suggestions such as Atlas, Cronus, Minerva,
Artemis, Vulcan, and Perseus - perhaps because it's so far from
the sun that it is in perpetual darkness.
- At Pluto's
farthest point from the sun, sunlight takes seven hours to
travel the 4.6 billion miles. Sunlight reaches Earth in eight
minutes.
- Scientists
estimate surface temperatures on Pluto can reach minus 400
degrees F.

Io: Power and
Noise But No Magnetic Field
Pasadena December
10, 2001 (NASA/JPL) - A great roar of acoustic waves near the north and
south poles of Jupiter's moon Io shouts about the power of the volcanic
moon.
The wave data, new pictures and other information collected recently by
NASA's Galileo spacecraft provide insight into what happens above Io's
surface, at its colorful volcanoes and inside its hot belly. Scientists
presented the findings Monday at a meeting of the American Geophysical
Union in San Francisco.
Galileo, managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif.,
has been orbiting Jupiter for six years. As it flew near Io's poles in
August and October, the density of charged particles it was passing
through suddenly increased about tenfold when the spacecraft crossed the
path of a magnetic-field connection between Io and Jupiter, reported Dr.
Donald Gurnett of the University of Iowa, Iowa City. The waves, indicating
the density, travel in a plasma of charged particles, and would be silent
to the ear, but Iowa researchers converted them to sound waves to make the
patterns audible.
"You hear a whistling sound from Jupiter's radio emissions, then,
just when you go over the pole, you hear a tremendous roar that starts
abruptly, then stops abruptly," Gurnett said. "It's like the
noise from a huge electrical power generator." Io actually generates
as much wattage as about 1,000 nuclear power plants.
The region of increased density is where electrons and ions come up from
Io's tenuous atmosphere and follow a "flux tube" where field
lines from Jupiter's strong magnetic field intersect Io. In a 1999 flyby
of Io, Galileo had provided some indication of the higher density over the
moon's poles. This year's two Io flybys were the first to show that those
denser areas coincide with the magnetic-field flux tube, Gurnett said.
Recent
magnetic-field measurements tell us something new about the plumes
erupting from Io's volcanoes and about the moon's molten core, said Dr.
Margaret Kivelson of the University of California, Los Angeles.
Galileo detected electrical currents flowing along magnetic field lines
above two areas of volcanic activity on Io, Kivelson said. Material shot
high from eruptions is apparently affecting conductivity more than 100
kilometers (about 60 miles) above the surface.
"If this is the mechanism that's producing the currents, it may help
us in the search for active plumes," she said.
Galileo's routes near Io's north pole in August and near its south pole in
October were chosen for gaining measurements to determine whether Io
generates an intrinsic magnetic field of its own within the greater
magnetic field generated by Jupiter.
"There's no intrinsic field," Kivelson said. "We can put
that question to rest." That means Io's molten iron core does not
have the same type of convective overturning by which Earth's molten core
generates Earth's magnetic field. Lack of that overturning fits a model of
Io's core being heated from the outside, by tidal flexing of the layers
around it, rather than being heated from the center.
The heat generated inside Io by the tidal tug of Jupiter makes this moon
the most volcanically active world in the solar system. A new color
picture of one large volcanic crater, Tupan Patera, shows various red,
green, yellow and black surface materials laid down by volcanic
interactions of molten rock and sulfur compounds, said Dr. Elizabeth
Turtle of the University of Arizona, Tucson. Tupan, named for a Brazilian
god of thunder, is one of Io's most persistent volcanoes. Another new
image reveals roofed-over portions of a long lava channel, indicating that
insulation provided by the cover helped lengthen a large lava flow.
New infrared imagery from Galileo shows that darker areas at Tupan
correspond to hotter surface materials, said Dr. Rosaly Lopes of JPL. The
infrared data also confirm sulfur- dioxide deposits near the source of a
tall plume seen in August above a previously inactive volcano.
VR Emergency
Medical for Manned Mars Mission
By Patricia Reaney
LONDON December 9, 2001 (Reuters) - If astronauts ever make it to Mars,
chances are that before they blast off on their epic journey they will be
trained on a virtual reality simulator to mend broken bones.
The first manned mission to the Red Planet isn't expected until about
2020, but Swiss surgeons and NASA scientists have already cemented a deal
to make sure if limbs are smashed on the way there or during a walkabout
they will be able to fix them.
With little room for outer space operating rooms in the cramped confines
of the interplanetary express, it will be a case of heal thyself, or each
other, for astronauts expected to make the round trip journey that could
take two years or more.
So NASA and the Swiss-based Association for the Study of Internal Fixation
(AO-ASIF) are developing a computer-based surgical simulator to train
surgeons on Earth and astronauts with tickets to Mars in the fine art of
trauma surgery.
A prototype for various operations will be available in around 2005.
"If we have simulators, not only orthopedic surgeons can be trained,
but NASA could use the simulators to train astronauts, because a journey
to Mars will be at least six months. So if they have any injuries another
person will have to help their colleague,'' said Dr. Andy Weymann, of the
AO foundation, who is working with NASA on the project.
The foundation, a non-profit organization of surgeons, pioneered internal
fixation -- using internal stainless steel or titanium plates, nuts and
bolts -- instead of plaster casts to heal fractures 40 years ago.
NASA is at the cutting edge of virtual reality technology, so the match
seemed a natural one.
"We are pretty sure that within the next three or four years we will
have a good simulator to train (surgeons and astronauts) with the
procedure,'' Weymann told Reuters in an interview.
Unlike casts, which immobilize broken bones and joints for many weeks and
can cause swelling, pain and redness, internal fixation prevents stiffness
of joints, ligaments and tendons and offers the possibility of pain-free
mobilization quickly after surgery.
Weymann said the operations, which can take from one to four hours
depending on the place and type of fracture, are cheaper and offer a
quicker recovery time than casts.
The plates and bolts can also be placed on the outside of the limb in a
procedure called external fixation.
Since the AO developed the method, it has trained more than 300,000
surgeons worldwide in the technique, which is used to treat up to 80
percent of fractures in some countries.
"It is not a cast. The bones are fixed with pins and these pins are
connected by bars,'' explained Dr. Christian Rys, the head of surgery at
Davos Hospital in Switzerland.
In addition to fixing limbs, the technique can also be used for
osteoporosis patients and in facial surgery.
"I don't believe they (NASA) will be able to take an operating room
into space, so they must use several procedures which can be performed in
a normal room, like an external fixation which is minimally invasive,''
said Rys.
First Pix of
Dark Matter
EARTH December 6, 2001 (NASA/ESA) - Astronomers have observed a Dark
Matter object directly for the first time. Images and spectra of a MACHO
microlens - a nearby dwarf star that gravitationally focuses light from a
star in another galaxy - were taken by the NASA/ESA Hubble Space Telescope
and the European Southern Observatory's Very Large Telescope. The result
is a strong confirmation of the theory that a large fraction of Dark
Matter exists as small, faint stars in galaxies such as our Milky Way.
The nature of Dark Matter is one of the fundamental puzzles in
astrophysics today. Observations of clusters of galaxies and the large
scale structure of individual galaxies tell us that no more than a quarter
of the total amount of matter in the Universe consists of normal atoms and
molecules that make up the familiar world around us. Of this normal
matter, no more than a quarter emits the radiation we see from stars and
hot gas. So, a large fraction of the matter in our Universe is dark and of
unknown composition.
For the past ten years, active search projects have been underway for
possible candidate objects for Dark Matter. One of many possibilities is
that the Dark Matter consists of weakly interacting, massive sub- atomic
sized particles known as WIMPs. Alternatively Dark Matter may consist of
massive compact objects (MACHOs), such as dead or dying stars (neutron
stars and cool dwarf stars), black holes of various sizes or planet-sized
collections of rocks and ice.
In 1986, Bohdan Paczynski from Princeton University realised that if some
of the Dark Matter were in the form of MACHOs, its presence could be
detected by the gravitational influence MACHOs have on light from distant
stars. If a MACHO object in the Milky Way passes in front of a background
star in a nearby galaxy, such as the Large Magellanic Cloud, then the
gravitational field of the MACHO will bend the light from the distant star
and focus it into our telescopes. The MACHO is acting as a gravitational
lens, increasing the brightness of the background star for the short time
it takes for the MACHO to pass by. Depending on the mass of the MACHO and
its distance from Earth, this period of brightening can last days, weeks
or months. The form and duration of the brightening caused by the MACHO -
the microlensing light curve - can be predicted by theory and searched for
as a clear signal of the presence of MACHO Dark Matter. MACHOs are
described as `microlenses' since they are much smaller than other known
cases of gravitational lensing, such as those observed around clusters of
galaxies.
Astronomers from the Lawrence Livermore National Laboratory, the Center
for Particle Astrophysics in the United States and the Australian National
University joined forces to form the MACHO Project in 1991. This team used
a dedicated telescope at the Mount Stromlo Observatory in Australia to
monitor the brightness of more than 10 million stars in the Large
Magellanic Cloud over a period of eight years. The team discovered their
first gravitational lensing event in 1993 and have now published
approximately twenty instances of microlenses in the direction of the
Magellanic Clouds. These results demonstrate that there is a population of
MACHO objects in and around the Milky Way galaxy that could comprise as
much as one half of the Milky Way total (baryonic/normal-matter) Dark
Matter content.
In order to learn more about each microlensing event, the MACHO team has
used Hubble to take high-resolution images of the lensed stars. One of
these images showed a faint red object within a small fraction of an
arc-second from a blue, main sequence background star in the Large
Magellanic Cloud. The image was taken by Hubble 6 years after the original
microlensing event, which had lasted approximately 100 days. The
brightness of the faint red star and its direction and separation from the
star in the Large Magellanic Cloud are completely consistent with the
values indicated 6 years earlier from the MACHO light curve data alone.
This Hubble observation further reveals that the MACHO is a small faint,
dwarf star at a distance of 600 light-years with a mass between 5% and 10%
of the mass of the Sun.
To further confirm its findings, members of the MACHO team sent in a
special application for observing time on the FORS instrument on the
European Southern Observatory's (ESO) Very Large Telescope (VLT)) to make
spectra of the object. ESO responded swiftly and positively to the
request. Although it was not possible to separate the spectra of the MACHO
and background star, the combined spectrum showed the unmistakable signs
of the deep absorption lines of a dwarf M star superimposed on the
spectrum of the blue main sequence star in the Large Magellanic Cloud.
The combination of the microlensing light curve from the MACHO project,
the high-resolution images from Hubble and the spectroscopy from the VLT
has established the first direct detection of a MACHO object, to be
published in the international science journal Nature on 6 December. The
astronomers now have a complete picture of the MACHO: its mass, distance
and velocity. The result greatly strengthens the argument that a large
fraction of the `normal' Dark Matter in and around our Galaxy exists in
the form of MACHOs and that this Dark Matter is not as dark as previously
believed!
Future searches for MACHO-like objects will have the potential to map out
this form of Dark Matter and reach a greater understanding of the role
that Dark Matter plays in the formation of galaxies. These efforts will
further strengthen the drive to reveal the secrets of Dark Matter and take
a large step towards closing the books on the mass budget of the Universe.
Mars Probe Sees
Possible Mars Climate Change
MARS December 7, 2001 (NASA) - The planet Mars we know today is a cold,
dry, desert world, but suppose the Martian climate is changing even now,
year to year and decade to decade?
New observations by NASA's Mars Global Surveyor spacecraft are expanding
our understanding of the Martian climate and may indicate the climate is
changing significantly even today. This suggests even larger climate
changes have occurred during the planet's recent history and may again in
its future. The observations were made during a full Martian year, 687
Earth days.
If this is so, Mars might someday become warmer and wetter, as some
scientists suggest it was during its early history. Papers detailing these
observations are published in the Dec. 7, 2001, issue of Science magazine.
"If the environment of Mars has really changed by as much and over as
short a time-scale as our observation implies, there should be attributes
of Mars reflecting these changes that may be measurable by landers,"
said Dr. Michael Malin, principal investigator for Global Surveyor's
camera system at Malin Space Science Systems, San Diego. "If Mars had
a higher atmospheric pressure in the not-too-distant past, it is more
likely that water was present as a liquid near the surface."
Liquid water is required to support known forms of life, and the presence
of liquid water on Mars would make it more likely life may once have
existed there.
"Detecting evidence of climate change and variability on Mars using
Mars Global Surveyor data is an important aspect of telling us where to go
on the surface this decade," said Dr. James Garvin, lead scientist
for Mars exploration, NASA Headquarters, Washington, D.C. "Clearly,
the polar regions are a good place where we would like to look for
hydrothermal vents to see if they exist on Mars."
Images from Global Surveyor's camera system show that pits -- often
referred to as the "Swiss cheese" terrain -- at the southern
polar ice cap of Mars have dramatically increased in diameter, indicating
the material has evaporated rapidly compared to last year.
"The amount of change is much larger than any previous change we've
seen on Mars, and it is much larger than can be explained by the
evaporation of water ice. We have calculated the only material that could
have changed this much is carbon dioxide ice, what we know as dry
ice," said Malin. "This means the Mars environment we see today
may not be what it was a few hundred years ago, and may not be what will
exist a few hundred years in the future."
A separate observation is providing more detail about the behavior of
carbon dioxide in the Martian atmosphere. Carbon dioxide is a
"greenhouse gas" believed to warm climates when its atmospheric
concentration increases. The spacecraft's laser altimeter and radio
tracking system have made precise measurements of the amount and density
of carbon dioxide snow in both polar regions. This information gives
scientists the first global measurement of the seasonal exchange of carbon
dioxide between the atmosphere and surface.
Due to the tilt of the planet, Mars has seasons just like Earth.
Scientists have long known the most important seasonal change on Mars is
the autumn and winter "freezing out" of carbon dioxide from the
atmosphere in the form of dry-ice frost and snow. The evaporation of the
surface frost in spring and summer returns carbon dioxide to the
atmosphere. Over the course of a Martian year, as much as a quarter of the
atmosphere freezes out, but until now scientists didn't know precisely
where and how much dry-ice frost and snow would pile up on the surface.
"We have measured how deep the dry-ice snow got on Mars over the
course of a year. We have also measured the corresponding tiny change in
the gravity field due to carbon dioxide being transported from one pole to
the other with the seasons," said Dr. Maria Zuber, deputy principal
investigator of the laser altimeter, at the Massachusetts Institute of
Technology, Cambridge, and NASA's Goddard Space Flight Center, Greenbelt,
Md.
"Snow on Mars is denser than snow on Earth and is really more like
ice than snow. Understanding the present carbon dioxide cycle is an
essential step towards understanding past Martian climates," Zuber
said.
X Prize Space
Race Heats Up
ST. LOUIS December 4, 2001 (PR Newswire) - X PRIZE competitor Steven
Bennett of Cheshire, UK recently completed an unmanned launch of his Nova
spacecraft, becoming the fourth X PRIZE entrant to successfully fly a
spacecraft prototype that eventually will take citizens to space. Bennett
is planning a piloted launch in Spring 2002, the next step in his quest to
capture the $10 million X PRIZE.
The St. Louis-based X PRIZE Foundation is awarding $10 million to the
first privately funded person or team to fly a three-person spacecraft to
100km on two flights within two weeks. The first space-based incentive
prize of its kind, the X PRIZE is modeled after the Orteig Prize, won by
Charles Lindbergh in 1927 for his historic transatlantic flight in the
Spirit of St. Louis. Bennett is one of 21 registered competitors from five
countries vying for the X PRIZE.
"The goal of the X PRIZE is to open space to tourism. Steve Bennett's
successful test flight puts our dream of getting to space one step
closer," said Peter H. Diamandis, founder and chairman, X PRIZE
Foundation. "His flight demonstrates the ability of small,
entrepreneurial teams from the private sector to successfully build
technology which was previously only possible by large governments."
"Following our success with Nova we will push ahead with a full-scale
test launch of our X PRIZE vehicle, Thunderbird, next year with the goal
of making an assault on the X PRIZE within 18 months," said Bennett.
"We intend to win the X PRIZE and open space for everyone."

India Considers
Unmanned Mission to the Moon
NEW DELHI, India December 12, 2001 (Reuters) - India's state-run space
program has begun a feasibility study for an unmanned mission to the moon,
the government said on Wednesday.
The four-decade-old Indian space program has been successful in making
communication and earth imaging satellites and launch vehicles for them,
but no exploratory missions into space have ever been launched.
"The trip to (the) moon will be entirely based on the conclusions of
the (feasibility) study," the government said in a statement.
No time-frame was given for the feasibility study.
The statement said the scientists of the Indian Space Research
Organization wanted to conduct experiments aimed at understanding the
lunar surface.
"India is embarking on the program in the backdrop of self reliance
achieved in the design, development and commissioning of communication as
well as launch vehicles and rockets," the statement said.
ISRO scientists have in the past said it could take them five to six years
to launch the mission, once the government gave the go-ahead. |

Christian Science Monitor Staff Writer
Washington December 6, 2001 (Christian Science Monitor) - Prejudice
against American Indians in the early 1960s kept his father from ever
mentioning - even to his family - what tribe they were from. But when
James Fortier's own son was born in 1993, he vowed it was time to break
the silence. So the San Francisco filmmaker not only searched out his
Ojibway relatives, but became a member of the tribe - and in 2000
identified himself for the first time on the United States Census as part
American Indian.
Stories like Mr. Fortier's were repeated again and again in the 2000
Census, which for the first time allowed people to mark down more than one
race.
Some 4.1 million Americans said they were at least part American Indian,
more than double the 1990 figure, and 2.5 million identified themselves
only as American Indian, a 26 percent increase. Both alone and in
combination with another race, American Indian figures "are rising
beyond anything that can be explained by birthrate," says Gabrielle
Tayac, a sociologist at the Smithsonian Institution's National Museum of
the American Indian.
Experts and tribal officials cite several reasons for the jump: Soaring
casino revenues and benefits from affirmative action and minority status,
enticing more tribal enrollees; a growing interest in genealogy, spurred
largely by the Internet; and an erosion of the American Indian stigma.
"It's cool to be an American Indian now," says Cherokee
spokesman Mike Miller, who has watched his tribe more than double to
230,000 members over the past decade, rivaling the Navajos as the
country's largest tribe.
"Wanting to identify with our heritage, people have gone back to
their roots to find some kind of Cherokee ancestry to qualify for
membership," he says, adding wryly that his tribe has no casinos.
There's no official figure available, however, for the increase in
membership of all 561 federally recognized tribes, leaving the census as
the most accurate count. And while a person's bloodline may be too thin
for tribal enrollment, it is no barrier to self-identification.
"It's the increase since the 1990 count that is so striking,"
says Dr. Tayac.
For decades, it was embarrassing and shameful to be considered American
Indian, says Joely De La Torre, a professor of American Indian studies at
San Francisco State University. American Indians avoided US Census forms,
largely because of their historical mistrust of federal officials who
expropriated their land. But in the late 1960s and early 1970s, civil
rights and Indian pride movements prompted many to embrace their roots for
the first time, she says.
More recently, sociologists refer to the effect of Indians portrayed in a
nobler light by popular culture. Movies such as "Dances With
Wolves," with Kevin Costner (1990), and Disney's
"Pocahontas" (1995) cause more people to acknowledge their
ancestry, the theory goes.
And Indians have "received more respect from society as they become
more professionally and economically developed," says Dr. De La
Torre, who is writing a book titled "American Indians: Political
Power in the New Millennium."
Fortier, for example, produced a movie on American Indians that aired this
year at the Sundance Film Festival, and he is working on another six-part
documentary for PBS. "I'm hoping to better educate the public so that
people can make their own informed decisions about the history of US
treatment toward American Indians," he says.
Last year, American Indians had more than 90 representatives at the
Democratic National Convention - the first time ever for any
representation at a presidential convention, De La Torre says.
This year, the Grammy Awards added a category for traditional native
American music. In 2004, the National Museum of the American Indian is to
move into new quarters in on the National Mall in Washington.
But what has fueled American Indians economically has also earned them
much criticism. Since 1988 - the year the US government allowed casino
gambling on reservations - 309 gaming operations have popped up. Gaming
revenue has soared from $212 million in 1988 to nearly $10 billion in
2000.
Many Americans disapprove strongly, but American Indians counter that
casino revenues have allowed them to accumulate capital for the first
time, enabling them to fund better schools, hospitals, and other
enterprises. The new revenue also entices those of Indian blood to enroll
in the tribe - and receive a share of casino stipends - and encourages
members to move back to reservations for the jobs and community.
The latest census also highlights the "millions of Americans who can
trace at least one root of their family tree to an American Indian,"
says Matthew Snipp, a sociology professor at Stanford University and
member of the Census Bureau's advisory committee on American Indians. In
the past, those with any hint of Indian ancestry often identified
themselves as of another race to escape discrimination. "Now, there
is less discrimination, and Americans can choose more than one race to
mark down," says Dr. Snipp.
But the new choice also raises questions about who has the right to claim
Indian status. There are those like Ten-nia Thomas, a full-blood Seneca,
who feels that being an American Indian has everything to do with blood
and lineage, even for those who know nothing of their traditional culture.
Others, such as Amber Arrow, who traces her roots to several tribes, point
to the vast numbers of American Indian children adopted out, or to lost
paperwork that could have verified a lineage.
"It's just one big mish-mosh now, but as long as you have it in your
heart and follow what your elders taught you, you're an Indian," she
says.
In coming years, federal and state agencies will also have to wrestle with
the daunting question of how to count mixed-race American Indians for
purposes of distributing federal money and enforcing minority rights, from
voting to the workplace.
Writing a fair funding formula based on the new census data will be
difficult, says Jay Mosa, research director at the Minnesota Department of
Economic Security.
He admits there's some frustration among his colleagues. But for the most
part, experts and tribal officials say the new census options are an
improvement, because they allow Americans to acknowledge a fuller,
multiracial heritage. Speaking for many, Fortier says: "Once I
discovered my American Indian family, I couldn't let go of it. Now it's a
real important part of my life." |

Head To Play Who
London December 11, 2001 (SciFi) - Anthony Stewart Head, who played Giles
on UPN's Buffy the Vampire Slayer, will voice Doctor Who in three segments
of the BBC's radio series, coming in February, Big Finish Productions
announced. Head has already recorded his performance for the segments of
the Excelis series of Doctor Who radio plays.
In the episodes, the Time Lord will face the wrath of the Warlord
Grayvorn, who, after meeting the fifth Doctor (Peter Davison) and Iris
Wildthyme (Katy Manning) in Excelis Dawns, is touched by an alien artifact
known as the Relic and becomes immortal. In the subsequent two Excelis
adventures, Grayvorn has to adopt alternate identities in his quest for
power over both the city of Excelis and the planet Artaris itself.
Head joins Davison, Colin Baker and Sylvester McCoy for the three stories.
Head recently moved back to his native England and has downscaled his role
in UPN's Buffy to a recurring character from a regular.
Joss Whedon
Considers Iron Man
By FRANK KURTZ
News Editor
Hollywood December 11, 2001 (CINESCAPE) - Joss Whedon has a number of
projects on his plate right now, one of which looks to see him making his
feature film directing debut with a certain armored Avenger.
While talking to CINESCAPE magazine, Whedon addressed what projects he's
currently looking at, saying, "IRON MAN is a definite possibility,
but you know we are talking about a major motion picture, so it won't be
any time soon."
He adds, "I'll probably end up doing another series before I do a
feature just because of the time a feature will take and my deal with Fox.
I'm looking to do a hard science fiction show. I am looking to do some
spaceship action. Something very different from what's gone before, but
ultimately it will exactly be the same as everything I do - women posing
with fisticuffs."
To read what else Whedon had to say about BUFFY THE VAMPIRE SLAYER and the
program's DVD release, check out the upcoming 57th issue of CINESCAPE, on
sale on January 8th.
Rings
Premieres to Deafening Screams
HOLLYWOOD December 11, 2001 (Zap2it.com) – An estimated 2,000 fans
greeted the cast of "The Lord of the Rings" in London at the
world premiere Monday night.
The enthusiasm for this first live-action adaptation of J.R.R. Tolkien's
classic novel overwhelmed even the usually jaded cast, who were deafened
by the shouts and screams of fans at Leicester Square.
Liv Tyler, 24, who plays the role of the elf-maiden Arwen in all three of
the upcoming films, told the Associated Press she was amazed by the
thunderous reception.
"I've seen nothing like this ever before," she said.
And co-star Christopher Lee, 79, who plays the 8,000-year-old wizard
Saruman told the AP, "No one has ever seen anything like it."
In an interview with Zap2it.com last year at the International Press
Academy awards, Lee said, "I wasn't aware that playing a role like
this would be so important, and as I got into the research and found out
more about the lore, I realized that this may be my signature role, and
not the horror films I'm now noted for."
Lee and Tyler were joined by Ian McKellen, who plays the wizard Gandalf,
and Elijah Wood, who plays the hobbit Frodo Baggins, at the premiere of
the first of the three movies titled, "The Lord of the Rings: The
Fellowship of the Ring.'' The Tolkein novels have all been filmed and will
be released over the next few years, each at Christmas time. The
50-year-old trilogy of books has sold more than 100 million copies and has
been translated to more than 40 languages.
"Heavenly Creatures" director Peter Jackson is responsible for
bringing the three books to life. The reported $300 million project was
shot in New Zealand and will be released by New Line.
Although crowds were bigger for the recent Warner Bros. release
"Harry Potter and the Sorcerer's Stone," it's possible this
latest book adaptation could give the boy wizard a run for his money at
the box office.
"The Lord of the Rings: The Fellowship of the Ring'' opens Dec. 19
worldwide.
Warner
Bros Lands Rights to Terminator 3
By Steve Gorman
LOS ANGELES December 11, 2001 (Reuters) - Warner Bros. Pictures has
clinched U.S. distribution rights to "Terminator 3," with Arnold
Schwarzenegger returning to his best-known role, capping a bidding war
among some of Hollywood's biggest studios, producers of the film said on
Tuesday.
Financial terms of the deal were not disclosed, but the production and
financing team behind the project reportedly had set its asking price at
$50 million plus half the gross receipts generated by the film.
For his part, Schwarzenegger, 54, will receive a record $30 million to
reprise his signature role as the lead-slinging, leather-clad cyborg from
the future in "Terminator 3: Rise of the Machines," a source
close to the production has told Reuters.
That would mark the highest up-front fee ever paid to a Hollywood star and
would exceed the $25 million Schwarzenegger reportedly made for playing
Mr. Freeze in "Batman and Robin."
"T3" is planned for summer 2003 release, giving Warner Bros. a
huge "tentpole" film to drive its business during one of the
busiest moviegoing seasons of the year.
The deal comes at a time when Warner Bros., a unit of AOL Time Warner
Inc., is dominating the U.S. box office with its all-star heist film
"Ocean's Eleven" and another key franchise property, the
record-smashing fantasy "Harry Potter and the Sorcerer's Stone."
They were the two highest-grossing films over the weekend.
MOSTOW HELMED SUB FLICK
Production on "T3" is set to begin in April with Jonathan
Mostow, who directed the submarine war movie "U-571," succeeding
James Cameron behind the camera of the latest "Terminator."
Entertainment trade paper Daily Variety has put Mostow's fee at $5
million.
According to Variety, producers have placed the overall cost of bringing
"T3" to the big screen at $165 million to $180 million, easily
eclipsing the record $135 million it reportedly took to make "Pearl
Harbor."
Several major studios, including Paramount Pictures, Universal Pictures
and the Walt Disney Co., were said to have been vying for rights to the
third installment of one of Hollywood's most potent franchises.
Interest was keen, given that "Terminator 2: Judgement Day"
grossed more than $500 million worldwide after its 1991 release. Experts
say a film franchise with such proven commercial clout normally has a
studio home by the time it gets to its third outing.
"It's very uncommon that a major franchise like this would be
available to the highest bidder," one knowledgeable industry source
said.
"Usually, a major franchise is developed by a studio," he said,
citing the "Star Trek" movies at Paramount Pictures and the
James Bond films at Metro-Goldwyn-Mayer. "To be able to buy into an
established franchise at any point is very rare."
MORE SEQUELS TO FOLLOW
Indeed, a joint statement issued late on Monday by the producers and
studio said "T3" would "set the stage for future
'Terminator' sequels."
A Warner Bros. spokeswoman said the rights acquired by the studio included
all forms of domestic distribution, including television, video and DVD
release.
While plot details of "T3" have remained a closely guarded
secret, the story is reportedly set 10 years after "T2," with a
20something John Connor and his T-800 cyborg pal, Schwarzenegger, battling
a female Terminatrix whose powers and morphing abilities exceed that of
their previous nemesis.
The film was sold
to Warner by the production company C-2 Pictures, whose principals, Mario
Kassar and Andrew Vajna, produced "T2," and its financing
partner, Intermedia Films. Two other Intermedia-backed films opened at No.
1 earlier this year -- "The Wedding Planner" and
"K-PAX."
C-2 and Intermedia expect to close their major overseas distribution deals
for "Terminator 3" by year's end.
Ironically, announcement of the Warner Bros. deal came as it was reported
that Schwarzenegger broke several ribs in a motorcycle accident over the
weekend in Santa Monica, California. But the Austrian-born star's
publicist promised, "He'll be back."
Paramount Pictures is a unit of Viacom Inc. . Universal Pictures is a unit
of Vivendi Universal.
Schwarzenegger
Breaks Ribs in Motorcycle Crash
LOS ANGELES December 10, 2001 (Reuters) - Action star Arnold
Schwarzenegger broke some ribs in a weekend motorcycle wreck, but like the
leather-clad cyborg he plays in the "Terminator" movies, he'll
be back, his publicist said on Monday.
The actor, 54, took a spill from his motorcycle in a "minor"
accident Sunday and was treated at a nearby hospital for several fractured
ribs, according to spokeswoman Jill Eisenstadt, who added she had no
further details.
"He's a very seasoned rider, and very safe rider, but accidents do
happen, and unfortunately he did have one yesterday," she said.
"He's resting comfortably and plans on coming home today."
Eisenstadt described Schwarzenegger as in "good spirits" and
said he planned to go ahead with plans to join his family for a skiing
vacation in Sun Valley, Idaho, over the Christmas holiday.
"So as only Arnold could say, he'll be back," the publicist
added, referring to Schwarzenegger's most famous line from the original
"Terminator" movie.
The Austrian-born actor is said to have recently clinched a record $30
million salary to reprise his role as the unstoppable man-machine from the
future for "Terminator 3." |
