Spacewalk May Be Needed
to Fix ISS Computer Breakdown (Source: Independent)
A computer breakdown on the International Space Station could require
astronauts to undertake a spacewalk. NASA confirmed on Friday that a
backup computer on the exterior of the ISS called a
Multiplexer-Demultiplexer (MDM) is not responding to commands.
MDM computers control some systems associated with robotics aboard the
space station. The primary MDM is functioning normally, NASA said, and
Mission Control is now trying to determine whether the back-up computer
can be brought back online or must be replaced. A replacement would
involve astronauts spacewalking. (4/12)
ISS Issue Might Delay
SpaceX Launch (Source: Waco Tribune)
The often-delayed launch of SpaceX Dragon cargo ship to the
International Space Station, set for Monday afternoon, may be delayed
yet again after a problem crept up with a computer module on the
station. The Multiplexer-Demultiplexer, or MDM, stopped responding to
commands, NASA said in a statement Friday evening. The unit, mounted
outside the ISS, backs up the main MDM in robotic-arm operations — such
as the one that will be needed to attach the Dragon to the station upon
its scheduled arrival Wednesday.
According to a NASA statement: "NASA is continuing to work toward a
Monday launch of the SpaceX cargo resupply mission pending further
evaluations by the ISS Program." (4/12)
The Otherworldly
Ambitions of Elon Musk (Source: San Jose Mercury News)
Elon Musk reigns over an entrepreneurial landscape of epic proportions:
With Tesla Motors, the cherub-faced CEO wants to wean us off fossil
fuels with electric cars for the masses. With SolarCity, he envisions
panels blooming on a million rooftops. And even as the fortunes of
these two firms soared on the SV150, this newspaper's latest index of
Silicon Valley's top public tech companies, Musk was laying the
groundwork for the world's biggest battery factory.
Yet this 42-year-old planet-saving, big-dreaming engineer has his
sights on a celestial prize: Mars. With SpaceX, the rocket company he
founded in 2002, Musk hopes to employ recyclable rockets to save
humanity, blasting earthlings into space to one day build settlements
on the Red Planet. "Mars is what drives him," said Louis Friedman, an
astronautics engineer who has known Musk for a decade.
Don't bet against him. Silicon Valley's most intrepid CEO already has
employed his potent combination of vision, determination and attention
to detail to accomplish two tasks widely thought impossible: creating a
viable new American car company with Palo Alto-based Tesla, and a
successful private space venture with Hawthorne-based SpaceX. Click here.

SpaceX, A Somewhat
Critical Look (Source: IEET)
I’ve been a bit baffled recently by the enthusiasm that so many friends
and colleagues have been displaying for SpaceX and the whole idea of
commercial space “exploration.” I don’t get it. I don’t doubt that what
SpaceX is doing, and what surely other commercial companies will soon
follow suit in doing, is important, and yes, even historical. But I
seriously doubt that it has much to do with space “exploration.”
More likely it is space exploitation. Don’t get me wrong: space is, to
some extent, a resource for humankind, and it is perfectly reasonable
for us to exploit it. And history has certainly shown that the best way
to accomplish that sort of task is to hand it to the private sector (of
course, that’s not at all without potentially extremely serious
drawbacks in and of itself, but that’s another story).
What history has also clearly shown is that basic science and
exploration are best done by scientists who work without the
constraints of financial interests, and these days this means
government funding (in Galileo’s time it was the government too, but in
the form of some rich nobel family running the city). Click here.

Human Lunar Missions
Subject of Debate at Exploration Workshop (Source: Space
News)
While a dozen space agencies, including NASA, have agreed upon a Global
Exploration Roadmap that lays out general plans for human missions
leading up to Mars, an April 10 workshop revealed continued
disagreement on the best way to get there, particularly regarding the
role of human missions to the surface of the Moon.
The NASA Community Workshop on the Global Exploration Roadmap, held at
the Applied Physics Laboratory here, brought together representatives
from NASA, industry and other space agencies to discuss the updated
version of the roadmap. That report, released last year by the
International Space Exploration Coordination Group (ISECG), a group of
12 space agencies, outlined pathways for human exploration leading to
humans on the surface of Mars.
“We all agree that, as a common, long-term goal, humans on the surface
of Mars is something we all strive for,” said NASA’s Roland Martinez.
In between the ISS and Mars, the report identifies three “mission
themes” for missions that eventually lead to Mars: missions to
near-Earth asteroids, the vicinity of the Moon and the surface of the
Moon. However, the sequence and schedule of missions in those three
areas remains unclear. (4/11)
ULA, SpaceX Lobby Up as
Launch Competition Looms (Source: Space News)
As they vie for hundreds of millions of dollars in national security
launch contracts, incumbent United Launch Alliance and newcomer SpaceX
have more than doubled their lobbying expenses in recent years.
According to data provided by the Center for Responsive Politics,
United Launch Alliance spent about $670,000 on lobbying efforts in
2013. That figure is up from the $120,000 the company spent in 2010,
according to the site.
SpaceX spent $1.1 million on lobbying in 2013, including hiring former
U.S. Sens. John Breaux and Trent Lott. The company’s lobbying costs
have risen steadily from about $568,000 in 2010. The higher spending by
both companies comes as lobbying spending across the defense aerospace
industry has shrunk. SpaceX’s lobbying costs are far less than those of
ULA’s parent corporations. ULA is a joint venture of defense giants
Boeing and Lockheed Martin. Combined, the two companies spend roughly
$30 million annually on lobbying efforts. (4/11)

Solar Array Issue Will
Have Little Impact on DMSP Mission (Source: SpaceFlight

U.S. Air Force officials say a partially deployed solar array boom on a
new military weather satellite will have "negligible" impact on the
$518 million spacecraft's planned five-year mission. The polar-orbiting
weather observatory for the Defense Meteorological Satellite Program
was shot into space April 3 on an Atlas 5 rocket, but it ran into a
problem extending its solar array boom.
The satellite's 10 solar cell panels, affixed on either side of the
boom, generate electricity for the spacecraft's systems and weather
instruments. "The team is currently working through a single anomaly
affecting the solar array boom," a spokesperson said. "The boom
successfully deployed, but stopped approximately 30 degrees short of
its nominal position, and did not lock into place." (4/12)
Georgia Spaceport: The
Transformation of a Company Town (Source: The Atlantic)
During the administration of the former submarine officer and former
Georgia governor Jimmy Carter, and with Georgia Senators Sam Nunn and
Herman Talmadge then big powers on Capitol Hill, the U.S. Navy decided
that Kings Bay, immediately north of St. Marys, would be the East Coast
home of America's nuclear-submarine fleet. (The West Coast home is near
Seattle.)
-- And looking toward space. The commercial space-launch business is
growing. According to local officials, this part of Georgia was in the
running when Cape Canaveral was chosen as NASA's main site in the
mid-20th century. And so they are making a 21st-century push to build a
new "spaceport" in a former industrial area (and one-time Thiokol
rocket-test site) just north of town, where companies like SpaceX would
be able to launch their vehicles. Click here.

How Urine Will Get Us to
Mars (Source: Science News)
Every day, you flush a liter or two of urine down the toilet. Unless
you live in one of the dry places considering toilet-to-tap systems,
you probably never consider drinking it. But if humans are ever going
to get to Mars, we’re going to get there drinking our own pee. Now
scientists have built a recycling system that can turn astronauts’
urine into both clean drinking water and energy. That combination could
be an important step in making long-distance space travel viable.
Astronauts report that the water made from recycled urine on the space
station tastes great. But the system keeps breaking down, and it takes
a lot of power to run it. The system “requires several consumables, and
filtered components are discarded,” says analytical chemist Eduardo
Nicolau.
The concept of the system he and his colleagues have come up with is to
not only remove urea from wastewater, but also “to generate valuable
components from human wastes instead of discarding them.” The new
system also generates electricity, scientists from NASA and the
University of Puerto Rico report. (4/11)
‘Cherry Tree From Space’
Amazes and Baffles Japan (Source: The National)
A cosmic mystery is uniting monks and scientists in Japan after a
cherry tree grown from a seed that orbited the Earth for eight months
bloomed years earlier than expected — and with surprising flowers. The
four-year-old sapling, grown from a cherry stone that spent time aboard
the International Space Station (ISS), burst into blossom on April 1,
possibly a full six years ahead of Mother Nature’s normal schedule.
The early blooming baffled Buddhist monks at the ancient temple in
central Japan where the tree is growing. “A stone from the original
tree had never sprouted before. We are very happy because it will
succeed the old tree, which is said to be 1,250 years old.” The wonder
pip was among 265 harvested from the celebrated
“Chujo-hime-seigan-zakura” tree, selected as part of a project to
gather seeds from different kinds of cherry trees at 14 locations
across Japan.
The stones were sent to the ISS in November 2008 and came back to Earth
in July the following year with Japanese astronaut Koichi Wakata, after
circling the globe 4,100 times. Some were sent for laboratory tests,
but most were ferried back to their places of origin, and a selection
were planted at nurseries near the Ganjoji temple. (4/11)

Space Coast High School
Satellite Prepares for Milestone Review (Source: Florida
Today)
In a Merritt Island High School classroom on a recent afternoon,
students in the school's StangSat club gathered to review a PowerPoint
presentation they've been working on for months. The group is in a
multi-year project with NASA engineers and mentors to build a
"cubesat," a satellite small enough to fit in the palm of your hand. It
will measure the shock and vibrations of the rocket during launch.
Students are preparing for an upcoming Critical Design Review, a
milestone after which they'll earn the "Go" to build the satellite that
will launch into space. The review details the satellite's progression
— from its successes and challenges to the risks associated with
launching the cubesat into space. That includes the high-altitude test
flight this summer in the Mojave Desert, when the satellite didn't turn
on as expected.
It's sister satellite, built by students at California Polytechnical
State University, had a bad solder joint on one of the resistors — and
it never sent the signal to the StangSat. "If we don't get turned on,
if our batteries are drained, if the software code is not correct,"
said Ryan Rohloff, a junior at Merritt Island High, of the risks
detailed in the review presentation. (4/11)
The Future That Wasn't:
Europe's Hermes Spaceplane (Source: America Space)
The genesis for Hermes, meant to be Europe’s answer to the United
States’ Space Shuttle, began in the early 1980s with France’s space
agency, CNES. It was proposed that Hermes, described in Jane’s
Spaceflight Directory 1986 as being “about half the size of the US
Shuttle,” would launch into space on an Ariane 5 rocket and land on
Earth like a plane. Jane’s also stated that development was to begin in
1988, with a launch to happen in 1997. More optimistically, the
Aerospatiale advertisement previously referenced stated Hermes would
“enter service in 1995.” Click here.
