The latest from NASA's Earth Observatory (23 December 2003)
* Weighing Earth's Water from Space
http://earthobservatory.nasa.gov/Study/WeighingWater/
Launched in 2002, a pair of identical satellites that make up NASA's Gravity Recovery And Climate Experiment (GRACE) are tackling the problem in an unexpected way: they are weighing Earth's fresh water from space. Serving as a sort of "divining rod" in space that moves in response to a powerful, fundamental force of nature--gravity--the satellites respond to changes in Earth's gravitation field that signal shifts in the movement of water a cross and under Earth's surface

In a move that may or may not help them wake up the Mars lander but will
definitely cause cat-person vs. dog-person tension throughout the
space-interested world, the Brits have put together a "Tiger" team to work
on waking up the Beagle 2. No signals from the lander during Odyssey
fly-overs again Sunday, and hopes continue to be fixed on next weekend's
arrival of the European orbiter in its listening orbit.

Beagle to begin 'frequent calls'
If Beagle is alive, it will call more frequently
British-built Mars probe Beagle 2 is due to switch into a communications
mode on Wednesday that increases the chances of contact being made with
it. If Beagle is intact on the Martian surface, it will automatically
begin "calling" Earth more frequently.
Two further attempts were made on Tuesday to contact Beagle with the Mars
Odyssey craft in orbit around the Red Planet, but with no positive
result.

A traveling robotic geologist from NASA has landed on Mars and returned
stunning images of the area around its landing site in Gusev Crater.
Mars Exploration Rover Spirit successfully sent a radio signal after the
spacecraft had bounced and rolled for several minutes following its
initial impact at 11:35 p.m. EST (8:35 p.m. Pacific Standard Time) on
January 3.
"This is a big night for NASA," said NASA Administrator Sean O'Keefe.
"We're back. I am very, very proud of this team, and we're on Mars."
Members of the mission's flight team at NASA's Jet Propulsion Laboratory,
Pasadena, Calif., cheered and clapped when they learned that NASA's Deep
Space Network had received a post-landing signal from Spirit. The cheering
resumed about three hours later when the rover transmitted its first
images to Earth, relaying them through NASA's Mars Odyssey orbiter.
"We've got many steps to go before this mission is over, but we've retired
a lot of risk with this landing," said JPL's Pete Theisinger, project
manager for the Mars Exploration Rover Project.
Deputy project manager for the rovers, JPL's Richard Cook, said, "We're
certainly looking forward to Opportunity landing three weeks from now."
Opportunity is Spirit's twin rover, headed for the opposite side of Mars.
Dr. Charles Elachi, JPL director, said, "To achieve this mission, we have
assembled the best team of young women and men this country can put
together. Essential work was done by other NASA centers and by our
industrial and academic partners.
Spirit stopped rolling with its base petal down, though that favorable
position could change as airbags deflate, said JPL's Rob Manning,
development manager for the rover's descent through Mars' atmosphere and
landing on the surface.
NASA chose Spirit's landing site, within Gusev Crater, based on evidence
from Mars orbiters that this crater may have held a lake long ago. A long,
deep valley, apparently carved by ancient flows of water, leads into
Gusev. The crater itself is basin the size of Connecticut created by an
asteroid or comet impact early in Mars' history. Spirit's task is to spend
the next three months exploring for clues in rocks and soil about whether
the past environment at this part of Mars was ever watery and suitable to
sustain life.
Spirit traveled 487 million kilometers (302.6 million) miles to reach Mars
after its launch from Cape Canaveral Air Force Station, Fla., on June 10,
2003. Its twin, Mars Exploration Rover Opportunity, was launched July 7,
2003, and is on course for a landing on the opposite side of Mars on Jan.
25 (Universal Time and EST; 9:05 p.m. on Jan. 24, PST).
The flight team expects to spend more than a week directing Spirit through
a series of steps in unfolding, standing up and other preparations
necessary before the rover rolls off of its lander platform to get its
wheels onto the ground. Meanwhile, Spirit's cameras and a
mineral-identifying infrared instrument will begin examining the
surrounding terrain. That information will help engineers and scientists
decide which direction to send the rover first.
JPL, a division of the California Institute of Technology, manages the
Mars Exploration Rover project for NASA's Office of Space Science,
Washington. Additional information about the project is available from JPL
at: http://marsrovers.jpl.nasa.gov and from Cornell University, Ithaca,
N.Y., at: http://athena.cornell.edu .

JPL engineers played Bob Marley's "Get Up, Stand Up" in the control room
as they watched new images confirming that the Mars Exploration Rover
Spirit successfully stood up on its lander late Thursday night Pacific
time, a major step in preparing for egress. This image from the rover's
front hazard avoidance camera shows the rover in the final stage of its
stand-up process. The two wheels on the bottom right and left are locked
into position, along with the suspension system. The martian landscape is

Spirit rover overloaded with files
http://www.cbc.ca/stories/2004/01/26/mars_rovers040126
Too many data files may have led to the crippling of NASA's Spirit
rover last week, the U.S. space agency said Monday.
Engineers weren't aware the hundreds of the data files would lead to a
major technical difficulty for Spirit. Since Jan. 22, the Mars robot
has been unable to send scientific data and images.
Now that NASA is aware of the limit, the files will be deleted from
Spirit and engineers will take care not to run into the same problem on
its twin, Opportunity, said Jennifer Trosper, mission manager for
operations on Mars' surface.
Problem solved? NASA scientists are giddy!
I found out the Mars day is just about an hour longer than the earth day.

Hubble finds farthest galaxies
http://www.cnn.com/2004/TECH/space/03/09/hubble.farthest/
Astronomers using the Hubble Space Telescope (HST) unveiled the
deepest look into the universe yet, a portrait of what could be the
most distant galaxies ever seen.
The new image, called the Hubble Ultra Deep Field (HUDF), includes
objects that until now have been too faint to be seen and includes
ancient galaxies that emerged just 700 million years after the Big Bang
theory from what astronomers call the "Dark Ages" of the universe.

Scientist attacks alien claims on Mars
By Robert Roy Britt
SPACE.com
Thursday, March 18, 2004 Posted: 5:25 PM EST (2225 GMT)
Richard Hoagland claims that NASA refuses to acknowledge evidence of alien
"artifacts" on Mars.
SPACE.COM: War of words to debunk aliens
(SPACE.com) -- Astronomer Philip Plait is tired of radio personality
Richard Hoagland's claims.
He's had enough of Hoagland's assertions that NASA is covering up evidence
of extraterrestrial life, that the infamous Face on Mars was built by
sentient aliens and, of late, that otherworldly machine parts are embedded
in the Red Planet's dirt.
And then there's the mile-long translucent martian worm.
On Hoagland's Web site, there are several images from various space probes
said to possibly show evidence for ETs. Recent Mars rover photos include
not just rocks, Hoagland and other contributors maintain, but common
objects that might tell of an alien civilization -- a bowl, a stove, a
piston.

Since 1983, Hoagland said he has led "an outside scientific team in a
critically acclaimed independent analysis of possible
intelligently-designed artifacts" on other worlds, using spacecraft data
from NASA and other missions.
Plait, author of "Bad Astronomy" (Wiley & Sons, 2002), which debunks space
myths and common factual misconceptions, had for years not countered
Hoagland directly, because he did not want to give a man he calls a
"pseudoscientist" the "air time that he so desperately seeks."
But last week Plait took his intellectual gloves off.
