Some Notes From Space Florida's Board Meeting (Source: SPACErePORT)
Space Florida's board met in Tallahassee on Wednesday. The board was asked to approve a new internal analysis of employee pay rates, and was advised that President Frank DiBello and Vice President Howard Haug are both currently working with expired contracts. Their contract status will be addressed in advance of the next board meeting. Five other contractual items were approved by the board, all related to funding projects with the Florida Department of Transportation (FDOT) at the Cape Canaveral Spaceport. The project beneficiaries were not named, due to confidentiality agreements...
Space Florida will work with FDOT to provide up to $5 million (to be matched by an unnamed partner) in FY-2013 toward modifying an existing launch facility for future Heavy Lift launch operations. Up to $1 million was approved for continued Spaceport Master Planning. A project requiring up to $20 million (from SF, FDOT and a commercial partner) was approved for the continued modification of KSC's Orbiter Processing Facility-3 (OPF-3) for one of NASA's Commercial Crew corporate partners.
Also for one of NASA's Commercial Crew partners, the board approved funding to assist the company in gaining Range Safety approval for their vehicle/operations, including covering some Range costs for the vehicle's initial launch from the Eastern Range. Editor's Note: Although not named during the meeting, the OPF-3 investment will likely support Boeing's CST-100 program, as the facility has been publicly dedicated to that program. As for the Range Safety approval, I'm guessing this involves Sierra Nevada and their Dream Chaser. (1/30)
Spaceport Informed Consent Bill Sails Through Senate (Source: Albuquerque Business First)
On Wednesday morning, the “informed consent bill” regarding Spaceport America passed the New Mexico Senate unanimously. The vote was 34-0, said Virgin Galactic spokesman Tom Carroll. The bill still has to pass the House, and garner the governor’s signature. The law, which will offer some liability protections for Spaceport suppliers, has been a priority for many businesspeople during this legislative session.
Virgin Galactic, the anchor tenant at Spaceport America, said passing the bill was critical to allowing the spaceport to function. Without it, the company has said, suppliers will not locate at the spaceport, and Virgin will likely not fly its rocket plane. The bill is next scheduled to go before the House Business and Industry Committee and could be heard as soon as Thursday. Gov. Susana Martinez has said she’ll sign the bill if it reaches her desk.

With a cost of $209 billion the politicos of New Mexico are putting out
the welcome sign to space travel companies by building this 18,000-acre
space park in the desert. And Spaceport America is inviting in the

Is Asia on Cusp of Space Race?
(Source: CNN)
The United States and Russia defined the world's first space race, but
following South Korea's successful orbital rocket launch this week, it
appears Asia -- particularly North Asia -- is the world's new epicenter
for space rivalries in the 21st century. "In some sense we are already
there," says Daniel Pinkston, North East Asia Deputy Project Director
for International Crisis Group in Seoul, South Korea. "The Chinese have
been very active... (also) Japan, North and South Korea. It's quite a
competitive atmosphere."
The race will only ratchet up later this year. In the second half of
2013, China will shoot for the moon with the aim of landing a rover
vehicle on its surface; building on exploration milestones in 2003 and
2012 with the first man, then woman, in space. India plans to send an
unmanned probe into Mars orbit this November. Click here.

Russia and Kazakhstan: What’s Behind

Russia and Kazakhstan seem headed for a showdown over rocket launches
at the Baikonur cosmodrome. Although Moscow and Astana are trying to
downplay their differences, both sides seem ready to play hardball in
what could be complicated and protracted negotiations.
Environmental concerns are ostensibly the catalyst for the discussions.
But an important subtext is sovereignty over the Baikonur launch site,
which is situated in northern Kazakhstan, but leased by Russia through
2050. And even though both nations are energy-rich, money too is an
issue.
A newly created intergovernmental commission is set to convene on
January 30 in Moscow to start probing for an agreement. Together with

Lockheed Martin Joins with Sierra
Nevada in Building Dream Chaser (Source: Denver Post)
Sierra Nevada Corp.'s Space Systems, based in Louisville, announced
this morning that Lockheed Martin is joining its efforts to build the
next-generation Dream Chaser spacecraft that could ferry American
astronauts into space in the next few years. Lockheed Martin will
specifically be in charge of building the composite structure for the
Dream Chaser, which looks like a compact version of the space shuttle
that was retired by NASA in 2011.
Lockheed will do its work at NASA's Michoud Assemby Facility in New
Orleans. Sierra Nevada, which has been awarded hundreds of millions of
dollars from NASA over the last few years, will work with the space
agency towards gaining government certification of the Dream Chaser.
It's not clear yet what the partnership will mean in the burgeoning
commercial space race, in which several companies are jockeying to be
the first to transport American astronauts to space once again.
Sierra Nevada's competition includes the Dragon space capsule from
California-based SpaceX and the CST-100 capsule from Boeing. The
seven-person Dream Chaser, which is 40-foot-long and 25-foot-wide, is
the only vehicle in the commercial space industry that would be capable
of landing on a runway upon its return to Earth. The competing vehicles
under development are capsules. Sierra Nevada hopes it can make its
first orbital test flight of the Dream Chaser in 2016. (1/30)

Official: No Crisis in Russia's Space
Work (Source: Space Daily)
Despite a recent string of failures, rumors of a crisis in the Russian
space industry are "absolutely wrong," the head of Russia's space
agency said. "This is absolutely wrong," Roscosmos head Vladimir
Popovkin said at a scientific meeting in Moscow. "We still have the
potential, the people who believe in space and ... rocket and space
enterprises capable of breakthrough projects."
The country's space program has experienced some very public setbacks
in recent years, most notably the failure of the Phobos-Grunt sample
mission to the martian moon Phobos, RIA Novosti reported. Russia's most
ambitious planetary mission in decades got stuck in Earth's orbit after
its engines failed to put it on course for the Red Planet in November
2011, and it crashed to Earth two months later. Roscosmos "burned its
fingers seriously" with the failure of the probe, Popovkin admitted.
"Probably, an outcome like this is logical," he said of the mission's
failure. "One company should not be allowed to design one scientific
spacecraft for such a long period, for 15 years." Roscosmos and the
Russian Academy of Sciences have established a working group to
coordinate future science and space projects, he said. (1/29)

How Worms Survived NASA's Columbia
Shuttle Disaster (Source: Space.com)
When the Columbia space shuttle disintegrated upon re-entry to the
Earth's atmosphere, killing all seven astronauts on board, NASA
scientists expected that the 80 science experiments aboard the shuttle
were destroyed as well. But in the days after the tragic Columbia
shuttle disaster on Feb. 1, 2003, scientists began realizing that
wasn't the case. Various salvageable experiments were recovered from
the wreckage, including a live group of 1 millimeter-long roundworms,
or nematodes, known as Caenorhabditis elegans.
No one expected that the nematodes could survive the intense heat of
re-entry, but the C. elegans got lucky, said Nathaniel Szewczyk, a
scientist who worked with the nematodes in the aftermath of the crash.
"They sustained some heat damage to exteriors, but that's about it,"
Szewczyk said. The thermos-size metal container holding the nematodes
was housed inside the locker of a crew compartment that was reinforced
specifically to protect the materials inside. Once that compartment
ruptured, however, the nematodes still survived the crash to Earth
thanks to the locker's build, Szewczyk said. (1/30)

Editorial: Sequestration’s Ugly Picture
(Source: Defense News)
As the U.S. military draws down, defense and military leaders stress
they must keep it from becoming a hollow force — a military that looks
good on paper, but incapable of performing as expected. Such hollowing
typically unfolds over many years as funding steadily declines, poor
personnel and program choices are made and vital training and
maintenance are slashed.
But in a message to his uniformed and civilian subordinates, Adm. Jon
Greenert, chief of naval operations, last week indicated that, should
automatic funding cuts go into effect under sequestration, and the
continuing resolution now funding government operations expire without
a budget to replace it, the force will be hollowed in six months.
Starting in April, maintenance for 30 of Navy’s 187 surface warships
and about 250 front-line aircraft could be deferred. Ships could be
stuck pierside as training funds dry up and Pacific and Middle East
deployments cut back.
There is reason for optimism. House Republicans have agreed to raise
the nation’s debt ceiling enough to give the Senate three months to
approve a budget, something the Senate hasn’t managed to do in four
years. But sequestration will kick in well before those budget talks
conclude, and lawmakers must find a way to avoid that disaster, too.
America needs a deal that averts sequestration and gives the Pentagon
budget guidance for 2014 and beyond. (1/30)

Republicans are reportedly concerned that any alternative would lead to
a much smaller overall deficit reduction. (1/29)

With Tesla and SpaceX Experience, Musk Offers Battery Observations to Boeing (Source: Flight Global)
The lithium ion batteries installed on the Boeing 787 are inherently unsafe, says Elon Musk, founder of SpaceX and owner of electric car maker Tesla. "Unfortunately, the pack architecture supplied to Boeing is inherently unsafe," wrote Musk in an email. "Large cells without enough space between them to isolate against the cell-to-cell thermal domino effect means it is simply a matter of time before there are more incidents of this nature," he adds.
Both Boeing and Tesla use batteries fueled by lithium cobalt oxide, which is among the most energy-dense and flammable chemistries of lithium-ion batteries on the market. While Boeing elected to use a battery with a grouping of eight large cells, Tesla's batteries contain thousands of smaller cells that are independently separated to prevent fire in a single cell from harming the surrounding ones.
An aerospace-capable version of Tesla's battery has been developed for use in SpaceX's Falcon 9 space launch vehicle. SpaceX, also owned by Musk, competes with Boeing/Lockheed Martin joint venture United Launch Alliance for customers. Boeing has thus far declined offers of assistance from Tesla and SpaceX, says Musk. (1/29)
Hubble Finds Appearances can be Deceptive (Source: Space Daily)
Globular clusters are roughly spherical collections of extremely old stars, and around 150 of them are scattered around our galaxy. Hubble is one of the best telescopes for studying these, as its extremely high resolution lets astronomers see individual stars, even in the crowded core.
The clusters all look very similar, and in Hubble's images it can be quite hard to tell them apart - and they all look much like NGC 411, pictured here. And yet appearances can be deceptive: NGC 411 is in fact not a globular cluster, and its stars are not old. It isn't even in the Milky Way. NGC 411 is classified as an open cluster located in the Small Magellanic Cloud, a small sister galaxy near our own. (1/30)
When a Planet Behaves Like a Comet
(Source: ESA)
ESA’s Venus Express has made unique observations of Venus during a
period of reduced solar wind pressure, discovering that the planet’s
ionosphere balloons out like a comet’s tail on its nightside. The
ionosphere is a region of weakly electrically charged gas high above
the main body of a planet’s atmosphere. Its shape and density are
partly controlled by the internal magnetic field of the planet.
For Earth, which has a strong magnetic field, the ionosphere is
relatively stable under a range of solar wind conditions. By
comparison, Venus does not have its own internal magnetic field and
relies instead on interactions with the solar wind to shape its
ionosphere. Click here.

Amateurs Help Discover Multi-Planet
System (Source: Sky & Telescope)
Earlier this month the Kepler mission announced yet another bevy of new
exoplanet candidates, their list now stretching 2,740 candidates long.
But Kepler’s not the only planet-hunter on the scene. A less splashy
study reported in January 10th’s Astrophysical Journal heralded the
second multiple-planet system discovered by microlensing, a technique
that makes good use of amateur astronomers’ skills and dedicated
telescope time.
To find a planet by microlensing, planet-hunters closely monitor
millions of stars in the Milky Way’s busy bulge. When a foreground
object, usually a star, passes between, it acts as a lens, momentarily
magnifying the light from the background star. If the lens is a simple
foreground star, the background star brightens and fades in a
characteristic pattern, but a planet orbiting the foreground star will
add a secondary spike. Only amateurs can dedicate near-continuous
coverage to capture the light curve’s details. (1/29)

This is a precarious moment for the U.S.'s future. But it is not too
late to change course and redirect our space agency to even greater
excellence and accomplishments in the 21st century. At this crucial
juncture, we should remember Kennedy's words. The path to any success

State Scrambles to Get NASA's OK for
Land to Build Launchpad (Source: Orlando Sentinel)
NASA is balking at plans by Space Florida to build a new commercial
launchpad near Kennedy Space Center, and now state officials — in both

to change its mind. Why the hurry? SpaceX of California is expected —
possibly this year — to choose where it wants to locate its next
launchpad — a potential cash cow for whatever state lands the facility.
Texas already has an early edge, and if Florida doesn't show progress
soon in securing the necessary land, then the state could lose out.

Here Is the Robot That Will Extract
Water From the Moon (Source: The Atlantic)
One of the biggest challenges of space travel has very little to do
with the traveling itself, and more to do with everything that happens
afterward. How will humans sustain themselves if we send them back to
the moon (and, as planned, to Mars)? Food, even freeze-dried, is heavy.
Water, too. Maintenance is expensive, in every sense of the word. So if
manned space travel is to become a long-term reality, we'll need to
find ways to cultivate the places and planets we visit: to mine their
soil for nutrients, to find the water hidden in their depths, to
generate the air that will make everything else possible.
NASA has an idea for doing all that, and it takes the form -- as so
many innovative ideas seem to these days -- of a robot. Meet ... the

Earth's neighborhood is littered with asteroids of all shapes and
sizes, ranging from fragments smaller than beach balls to mountainous
