Hubble telescope will get upgrade
(Oct 31, 2006)
NASA chief Mike Griffin says shuttle astronauts will be sent to service
the Hubble Space Telescope.
The orbiting observatory has astounded astronomers and the public
alike with its amazing imagery of the cosmos, but it will soon fail
unless serviced. Mr Griffin told NASA employees that recent modifications
to the shuttle launch system meant he felt it was now safe to send
a crew to work on Hubble. The mission, which has been designated STS-125,
should launch in 2008.

Bizarre stellar outburst continues to
baffle
(Oct 31, 2006)
A strange outburst of the star V838 Monocerotis several years ago
is continuing to mystify astronomers. A new study backs the idea that
it was the result of a collision with another star. When V838 Mon
brightened in January 2002, many astronomers thought it was a regular
nova – a nuclear explosion on the surface of a dead star called
a white dwarf. Such explosions are triggered by the white dwarf stealing
matter from a nearby stellar companion.

NASA's Spitzer peels back layers of star's
explosion
(Oct 30, 2006)
Astronomers using NASA's infrared Spitzer
Space Telescope have discovered that an exploded star, named Cassiopeia
A, blew up in a somewhat orderly fashion, retaining much of its
original onion-like layering. "Spitzer has essentially found key missing
pieces of the Cassiopeia A puzzle," said Jessica Ennis of the University
of Minnesota, Minneapolis, lead author of a paper to appear in the
Nov. 20 issue of the Astrophysical Journal.

NASA to decide Hubble's fate
(Oct 29, 2006)
NASA is debating whether to send astronauts on a mission to repair
the Hubble Space Telescope.
Without another servicing call by shuttle astronauts, Hubble is expected
to last another two to three years. At the crux of this is whether
to risk flying astronauts on the shuttle without the International
Space Station available as an emergency shelter.

Soil minerals point to planet-wide ocean
on Mars
(Oct 27, 2006)
An ocean of water once wrapped around Mars,
suggests the discovery of soil chemicals by NASA’s rovers.
But the same chemicals also indicate that life was not widespread
on the planet at the time the ocean was present. Sulphates, which
form most readily in liquid water, had already been detected by the
Spirit and Opportunity rovers. The minerals have been interpreted
as evidence for past bodies of water on the surface. But it has not
been clear how large these bodies of water might have been.

Undergrad proposes asteroids as radiation
shields
(Oct 27, 2006)
NASA is funding a study to see if it might be possible to use asteroids
traveling between the orbits of Earth and Mars
to shelter spacecraft from radiation. The study is the brainchild
of Daniella Della-Giustina, engineering physics undergrad –
and maybe science fiction writer Arthur C. Clarke.
Della-Giustina is one of five people to receive NASA's Advanced Concepts
Student Fellows Prize this year.

Marooned Mars rover returns stunning panorama
(Oct 26, 2006)
The most detailed panoramic view ever obtained on Mars
has been returned by NASA's Spirit rover in time to mark its 1000th
Martian day, or sol, on the Red Planet. A total of 1449 individual
images representing 500 megabytes of raw data were acquired for the
view, called the McMurdo panorama.

What are the chances of aliens sniffing
us out?
(Oct 25, 2006)
Beaming signals into space to find ET could potentially be risky for
Earth and its inhabitants. So researchers are developing a Richter-like
scale to assess the chance that extraterrestrials could detect –
and potentially react to – such signals. Decades of passively
monitoring microwave frequencies have failed to find any evidence
of signals from extraterrestrial civilisations. Frustrated by the
long silence, some researchers want to start transmitting signals
towards nearby stars with possible habitable planets in a plan called
"active SETI".

Viking landers may have missed Martian
life
(Oct 24, 2006)
NASA's twin Viking
spacecraft may have missed signs of life during their examination
of the Martian surface
30 years ago. Researchers now say that the landers’ experiments were
not sensitive enough to find life and in any case may not have been
able to spot the strange forms that Martian life might take. The results
from Vikings’ onboard experiments are confusing because some tests
suggested the presence of organisms capable of digesting organic molecules.

Introducing: Thunderhawk – first
X-Racer officially named
(Oct 23, 2006)
Its official. The Rocket
Racing League announced today that its first Mark-1 X-Racer
will be known as the Thunderhawk. The Rocket Racing League (RRL) is
an aerospace entertainment organization which combines the competition
of racing with the excitement of rocketry.
