CNES, ASI Favor Solid-Rocket Design
For Ariane 6 (Source: Aviation Week)
If things had gone according to plan, Europe would be flying a more
powerful and efficient version of its Ariane 5 rocket today, one that
could compete in the commercial market without public subsidies, and
development of a next-generation launcher would be well underway.
Instead, the Ariane 5 suffered a serious failure in 2002 that slowed
plans to boost its performance and shelved what were mostly French
ambitions to start work on a less costly successor.
An evolution of the Ariane 5 ECA that now delivers roughly half of the
world's communication satellites to orbit each year, the enhanced
Ariane 5 ECB would have entered service in 2006. But it was 2008 before
the European Space Agency (ESA) approved low-level funding for early
development. The project was rebranded the Ariane 5 Midlife Evolution
(Ariane 5 ME), and the money—roughly €300 million—started to flow, most
of it going to Ariane 5 prime contractor Astrium Space Transportation's
facility in Bremen, Germany. (10/16)
At Pluto, Moons and Debris May Be
Hazardous to New Horizons (Source: APL)
NASA’s New Horizons spacecraft is now almost seven years into its
9½-year journey across the solar system to explore Pluto and its system
of moons. Just over two years from now, in January 2015, New Horizons
will begin encounter operations, which will culminate in a close
approach to Pluto on July 14, 2015, and the first-ever exploration of a
planet in the Kuiper Belt.
As New Horizons has traveled through space, its science team has become
increasingly aware of the possibility that dangerous debris may be
orbiting in the Pluto system, putting the spacecraft and its
exploration objectives into harm’s way. “We’ve found more and more
moons orbiting near Pluto — the count is now up to five,” says Alan
Stern, principal investigator of the New Horizons mission. “And we've
come to appreciate that those moons, as well as those not yet
discovered, act as debris generators (10/16)

Kepler's Exoplanet Survey Jeopardized
by Two Issues (Source: SpaceFlightNow.com)
NASA's Kepler space telescope, a sleuth with electronic eyes, needs an
extra four years to meet its goal of finding an Earth-sized planet in
habitable zones around other stars, but a critical hardware failure
aboard the probe this summer has managers worried the mission could end
at any time. Two issues with Kepler have the attention of scientists
and engineers.
On July 14, one of the spacecraft's four reaction wheels stopped due to
increasing friction. The spinning masses control Kepler's orientation
in space and keep the telescope locked on to target stars. Borucki said
engineers will ensure Kepler's three active reaction wheels stay warm
and alternate their rotation between clockwise and counter-clockwise
directions. Officials believe the measures will help the wheels remain
healthy.
Although Kepler's 95-megapixel digital camera is plenty sensitive,
bands of noise appear in raw imagery streaming down from the telescope.
Scientists have devised complex algorithms to remove the meaningless
data. And despite the best estimates of scientists before Kepler's
launch, most of the sun-like stars in Kepler's field-of-view show more
variability than projected. Coupled with the noisy data derived from
technical causes, the variability issue means astronomers need more
data to confirm a dip in a star's luminosity is from a transiting
planet. (10/16)
Computer Models of Earth's Climate
Change Confirmed on Mars (Source: Reuters)
Computer models have accurately forecast conditions on Mars and are
valid predictors of climate change on Earth, U.S. and French
astronomers said on Tuesday. These computer programs predicted Martian
glaciers and other features on Earth's planetary neighbor, scientists
found.
"Some public figures imply that modeling of global climate change on
Earth is 'junk science,' but if climate models can explain features
observed on other planets, then the models must have at least some
validity," lead researcher William Hartmann said. The team's findings
were presented at the annual meeting of the American Astronomical
Society's planetary sciences division in Reno, Nevada. (10/16)

Baumgartner Skydive: One Rather
Helpful Leap for Space Tourism (Source: Telegraph)
Even the most hardened thrill-seeker might have been expecting to read
Felix Baumgartner’s obituary by now. After all, there were a myriad of
gruesome ways in which the Austrian daredevil could have expired: an
unscheduled, premature plunge if the fragile, relatively untested
helium balloon in which he was ascending had been punctured; a pinprick
tear in his spacesuit that would have caused his blood to boil in the
thin, unforgiving air of the stratosphere; an uncontrolled “death spin”
as he plummeted more than 24 miles to Earth; or losing consciousness
during the supersonic descent and becoming unable to open his parachute.
Instead, on Sunday night, Baumgartner broke three aviation records –
for height reached in a balloon, for highest skydive, and above all for
the speed with which a human being has fallen, reaching 833 mph, or
Mach 1.24. Perhaps most significantly, however, he kept the dream of
space as a playground alive. It is no coincidence that, as Baumgartner
coolly touched down in the New Mexico desert and dusted himself off,
some of the first congratulatory messages came from retired and serving
astronauts. Click here.

Changing Orbit: NASA Commercializes
Space Travel, Focuses on Exploration (Source: Daily Orange)
The SpaceX rocket launched a new era in space travel last week when it
became the first official commercial space flight to travel to the
International Space Station. Last week’s launch was the first official
flight, but a test run without cargo was completed five months earlier
to ensure the mission would be successful.
Achille Messac, department chair for mechanical and aerospace
engineering, said in an email that commercializing space flight is a
huge development for the industry. “This is a truly exciting time for a
new generation of aerospace engineers,” he said. “Things are much more
fluid in the commercial sector. Much more is possible.” The new
commercial vehicles will be cheaper, reusable and more reliable, Messac
said.
In the past, NASA’s primary role was exploration. Now that the industry
has been commercialized, NASA is able to narrow its focus. It can now
prioritize exploration, as seen in its recent launch of the rover
Curiosity to explore Mars, Ballmer said. Cathryn Newton, professor and
dean emerita of earth sciences, said commercializing space flight was a
logical progression. (10/16)
Editorial: Space Exploration Has a
Future (Source: The MSU Reflector)
One of the more controversial issues in science policy over the past
decade has been the privatization of space exploration. There has been
a general shift from NASA being in charge of every aspect of American
spaceflight to private companies developing their own rockets and
following the market to participate in space flight.
Just last year, the Obama administration decided to shut down the
shuttle program, permanently retiring the remaining four shuttles to
museums around the country. The goal of this move was not to cripple
American ingenuity or science, but actually to avoid expensive cost
overruns which were common in the shuttle program and to promote the
private sector’s growth in aerospace industry.
My dream is one day rockets or spaceships of some sort will lift off
every hour, taking miners up to scour the asteroid belt and taking
valuable resources to bases on the moon and in stable orbits around
Earth and possibly Mars. It is not too far-fetched, and even with a
little hitch like a dip in government funding, space exploration does
not look like it is going anywhere but up anytime soon. (10/16)

In Space: An Odd Obama Success
(Source: USA Today)
When SpaceX's "Dragon" capsule docked with the Space Station last week,
one angle was surprisingly underplayed: The SpaceX success is also a
success for the Obama administration's space policy. Since Barack Obama
took office in 2008, U.S. space policy has shifted in a surprisingly
free-market direction. Despite the Obama crowd's general enthusiasm for
big government, where space policy is concerned they've taken a
decidedly different approach: Instead of building its own rockets, the
government is now buying launch services from private companies that
are largely free to build their own rockets and choose their own
approaches.
There's nothing new about this idea. The federal government did the
same kind of thing in the 1920s with air mail contracts, and that
program -- along with wind tunnels and other R&D assistance
provided by NASA's predecessor, the National Advisory Committee on
Aeronautics -- did a lot to establish U.S. dominance in civil and
military aviation in the 20th Century. I wrote articles and position
papers advocating such an approach more than two decades ago.
But now that it's happening under the Obama administration, some
conservatives are criticizing them. This led space expert (and former
congressional staffer) Jim Muncy to comment "Democrats don't think that
capitalism works within the atmosphere, and Republicans apparently
don't think it works above it." But, in fact, capitalism works
everywhere. (10/15)
Suit Built for Free Fall From Space
May Not Have Future at NASA (Source: KHOU)
Felix Baumgartner survived his record breaking leap from 24 miles above
Earth on Sunday thanks in part to a special pressurized suit that
experts say could help save the lives of future astronauts—except NASA

man, clearly, to have done what he has done. But this project is
anything but a daredevil act," said Dr. Leroy Chiao.
Dr. Chiao works with the Baylor College of Medicine Center for Space
Medicine where some of the testing was done on the high tech suit worn
in the jump. So does Dr. Jon Clark, who lost his wife Laurel when the

It likely will be decades before an American astronaut sets foot on

Moon Water Mystery: Scientists Point
to Solar Wind as Origin (Source: Space.com)
Glass beads within moon rocks suggest that water seen on the lunar
surface originates from the solar wind, researchers say. These findings
suggest that other airless bodies in the solar system may also possess
water on their surfaces, investigators added. Arguments raged for years
as to whether the moon harbored frozen water or not. Recent findings
confirmed that water does wet the moon, although its surface remains
drier than any desert on Earth.
"With the cost of $25,000 for taking one pint of water to the moon, it
is essential that we develop processes of producing water from the
materials on the moon," said the study's lead author, Yang Liu, at the
University of Tennessee at Knoxville. "This is paramount to human
settlement of the moon in the near future." "This water would be of
most value as rocket fuel — liquid hydrogen and liquid oxygen," Liu
added. "Until the recent discovery of water in and on the moon, this
was going to be a very energy-intensive endeavor to separate these
elements from the lunar rocks and soil. (10/15)
Could a Moon of Uranus Harbor an
Underground Ocean? (Source: Nature)
Since 2005, astrobiologists have considered Enceladus a possible haven
for life, after the Cassini mission found that the icy moon of Saturn
shoots out plumes of water through fissures in its crust. But planetary
scientists Elizabeth Turtle of Johns Hopkins University Applied Physics
Laboratory, and Julie Castillo-Rogez of NASA’s Jet Propulsion
Laboratory are now turning their eyes to an even more distant Solar
System locale: Ariel, a moon of Uranus that they think could also
harbour an underground ocean.
Like Enceladus, Ariel’s surface appears relatively blemish free, with
few large craters, as if recent activity had erased or buried older
pockmarks. Flow-like features on Ariel suggest icy volcanism may have
been responsible for the facelift, as it has on Enceladus. But in the
frigid depths of the outer Solar System, what could maintain an ocean
beneath the surface of Ariel?
The flexing of Ariel due to the gravitational tug of others moons—is
five times greater on Ariel than Enceladus. In addition, both moons
contain a relatively large amount of rock, which generates heat through
the decay of radioactive elements within it. Heat from the rock would
increase the internal temperature of Ariel to the point where ice would
be soft enough to respond to tidal flexing, Castillo-Rogez says.
Although the Uranian system is colder than of Saturn system, the
Uranian moons are more likely to have captured impurities that would
decrease the melting temperature of ice. (10/15)
Does CCAFS Have a Moon Tree?
(Source: SpaceKSC)
In January 1971, Apollo 14 launched from Kennedy Space Center. Among
the items onboard were hundreds of tree seeds in the personal kit of
Command Module pilot Stuart Roosa. Because Roosa remained in the
Command Module while his two crewmates descended to the lunar surface,
the seeds never actually were on the Moon. But they came to be known as
Moon Trees. Five different seeds were flown — Loblolly Pine, Sycamore,
Sweetgum, Redwood, and Douglas Fir. The seeds were given to the U.S.
Forest Service, which distributed them across the nation and around the
world.
Accurate records of their distribution were not kept, so their
whereabouts are largely unknown. One Moon Tree is a sycamore at the
Kennedy Space Center Visitor Complex. Last week, I was approached by a
local space historian who told me that another sycamore Moon Tree was
planted at what is now the Space Florida complex outside Gate 1 of Cape
