Private Space Travel Is
Worth the Risk, If Done Right, Experts Say (Source:
Space.com)
Space tourism and commercial space mining projects are
ushering in a new era of human spaceflight, but their success of
private spaceflight will depend on ensuring safety and reducing the
cost, experts say. Spaceflight companies such as SpaceX or Space
Adventures, Ltd. could make the dream of space travel a reality for
some, and may take on the role NASA once had in pushing the frontier of
space, a panel of experts said.
The 19th-century adventurers Lewis and Clark, for example, weren't the
actual people who colonized Montana, said Michael Gold, director of
Washington, D.C., operations and business growth for the Bigelow
Aerospace, a company that is developing private inflatable space
stations. It was the homesteaders, the farmers and the businessmen who
followed later. "You can't just go to space like Montana homesteaders
and pitch a tent," said Neil deGrasse Tyson.
Like all new forms of travel, private spaceflight carries significant
risks. But the panelists said they didn't see the risks as
insurmountable. Ultimately, a bad safety record would hurt companies.
"There's a perception that commercial space is less safe," Gold said.
But "if we have a bad day, we lose everything." But beyond having a
good safety record, it's important to understand the risks, Austin
said. "It doesn’t matter how safe [a spaceship] has been, it matters
what one you're sitting on." (3/22)
Spaceflight Museum Moves
to Larger Site (Source: Florida Today)
A museum dedicated to preserving the history of manned spaceflight will
move in May to a larger location on U.S. 1 alongside other historic
buildings in downtown Titusville. The U.S. Space Walk of Fame Museum
will nearly triple the area to display its equipment, memorabilia and
relics that are squeezed into its current location on Main Street.

Pair of KSC Launches
Planned for Next Week (Source: Florida Today)
Spring Breakers could enjoy two Space Coast launches in the next week.
A United Launch Alliance Atlas V rocket is expected to roll to its pad
Monday morning in preparation for a 2:48 p.m. Tuesday launch of a
National Reconnaissance Office satellite. Then late next Sunday, SpaceX
plans to launch cargo to the station from Cape Canaveral, in a Dragon
capsule atop a Falcon 9 rocket. Liftoff is targeted for 10:50 p.m., an
instantaneous window. (3/22)
Doubt Cast on Evidence
for Wet Moon (Source: BBC)
Scientists have cast doubt on a major part of the case for the Moon
having once held abundant water. A US team studied a mineral called
apatite, which is found in a variety of lunar rock types. Apatite may
have misled scientists into thinking the Moon is wetter than it
actually is. Lead author Jeremy Boyce said: "We thought we had a great
indicator, but it turns out it's not that reliable."
They simulated the formation of apatite minerals containing different
amounts of volatile elements - hydrogen, chlorine and fluorine. They
demonstrated that it was possible to start with any water composition
in the magma and, by varying only the degree of crystallisation and the
chlorine content, reproduce all the features seen in a diverse range of
apatite from the Moon. (3/22)
Moon Camera Sale Soars
Sky High Despite Questions About History (Source: Collect
Space)
A camera claimed to have been used on the moon's surface sold for
almost $1 million in Austria Saturday (March 22), despite concerns
about its history. The WestLicht Photographica Auction in Vienna
registered a hammer price of 550,000 euros (660,000 euros with the
buyer's premium, or about $910,400 US) for a Hasselblad Electronic Data
Camera (EDC) that the gallery described as having been used by
astronaut James Irwin during the Apollo 15 mission.
The final sale price far surpassed the 150,000 to 200,000 euros (about
$200,000 to $275,000) that WestLicht had estimated. If the camera sold
by WestLicht is the same Hasselblad EDC that Irwin used to take 299
photos while exploring the moon, then it is not clear how it made its
way from federal property to private hands.
A 2012 law made it legal for the Apollo-era astronauts to own, and if
so desired, sell the spent equipment that they brought home as
mementos. But as the Apollo 15 camera was never a souvenir and did not
originate from Jim Irwin's estate, that law does not apply. (3/22)
Ariane Launches Astra 5B
and Amazonas 4A Satellites (Source: NasaSpaceFlight.com)
Arianespace lofted another two more satellites into orbit – namely
Astra 5B and Amazonas 4A - via their Ariane 5 ECA rocket on Saturday.
Launch from the European Spaceport in Kourou, French Guiana was delayed
by 24 hours due to unacceptable rollout weather. However, Saturday
proved to be no problem, with launch occurring at the opening of the
window at 10:04pm UTC. (3/23)
Kuratite: New Mineral
Discovered in Meteorite (Source: Sci-News)
The stony meteorite D’Orbigny is the source of a newly discovered
mineral, kuratite. Its name honors Dr Gero Kurat (1938-2009), a
world-renowned meteorite researcher and long-term head of the
Mineralogical-Petrographical Department at the Natural History Museum
in Vienna, Austria. The meteorite D’Orbigny, a 16.55-kg stone mostly
covered with dark gray fusion crust, was found by a farmer plowing a
corn field in July 1979 in Buenos Aires, Argentina.
Confirmation of it’s extraterrestrial status was finally achieved in
2000 after a sample was analyzed by Dr Kurat and his colleagues. The
meteorite was determined to be an exceedingly rare achondrite known as
an angrite. It is characterized by prominent vesicles which are rarely
seen in meteorites. (3/21)
The Future of Satellites:
What are the Options? (Source: Defense Systems)
DOD’s demand for bandwidth is increasing unabated as funding is being
trimmed, forcing agencies to cut costs without scaling down
capabilities. Meanwhile, the price of traditional satellite deployments
continues to rise. A GPS satellite, for example, cost $43 million to
build and $55 million to launch in early 1990s. A GPS III satellite
will cost about $500 million and $300 million to launch.
So DOD is exploring a range of cost-cutting options for satellite
communications that includes making technical changes, altering
management strategies and using new launch techniques. At the same
time, every study predicts a substantial increase in demand for
bandwidth to support unmanned aerial vehicles, wireless devices and
many other applications. That’s prompting strategists to re-examine
every aspect of satcom — from launch methods to the terminals used on
the ground — to improve efficiency. (3/21)
Satellite Industry Frets
About Future Military Business (Source: National Defense)
The Pentagon spends about a billion dollars a year on satellite
communications services from commercial vendors, which supply about 80
percent of the military’s demand. The industry is worried, however,
about the future of its Defense Department business, for several
reasons. Much of the demand for satellite communications, or satcom,
was generated by wars that are coming to an end.
The Pentagon sees its future in Asia-Pacific, but has yet to share with
vendors how it plans to acquire satcom in the region. Commercial
satellite providers generally detest the Defense Department’s satcom
buying methods because they favor one-year leases instead of the
long-term agreements that private-sector investors prefer.
Suppliers also fear that the Pentagon, as budgets shrink, will pare
back spending on commercial services and will rely more on
military-owned satellites. Pentagon officials insist that these
concerns are unfounded. They cite projections of soaring demand for
commercial satcom in the coming years to satisfy the military’s
appetite for data, for global connectivity and for bandwidth-hogging
drones. (3/21)
Why is Syria Launching a
Space Program During a Civil War? (Source: The Verge)
This week, as the civil war in Syria entered its fourth year, the
government of President Bashar al-Assad announced plans to create the
country's first space agency. The state-run SANA news agency did not
indicate what kind of projects the Syrian Space Agency will undertake,
saying only that they will be "of a scientific and research nature,"
nor did it specify how much it would cost to start up. The goal, it
said, is to use "space technology for exploration and observing the
Earth."
But there are doubts about the government's ability to launch a space
program in the middle of a civil war that has ravaged Syria's economy
and forced many of its best scientists to seek refuge in other
countries. More than 140,000 people have been killed since unrest broke
out between the Assad regime and various rebel groups in March 2011,
and about 2.5 million have fled the country, according to estimates
from the United Nations. Peace negotiations between the government and
opposition groups ended in deadlock earlier this year, and the violence
has shown no signs of letting up.
This week's announcement may be an attempt by government leaders to
quell fears over its limping economy; during the same cabinet session,
the country's prime minister insisted that Syria's economic situation
remains stable and that attempts to stabilize its currency were
effective. (3/21)
