Bigelow BEAM Successfully Expanded at
ISS (Source: SpaceFlight Insider)
The Bigelow Expandable Activity Module (BEAM) was successfully expanded
today, May 28, on board the International Space Station (ISS), two days
after an attempt to inflate the module brought an unexpected pressure
increase with little-to-no increase in size.
Expansion started just after 8 a.m. CDT when NASA astronaut Jeff
Williams opened the Manual Pressure Equalization Valve (MPEV) for 22
seconds to let a burst of air inside BEAM. This got the pressure back
and size back to where the module was two days prior.
Williams let in air manually in order to methodically increase the size
of BEAM before the onboard tanks take over to pressurize the internal
volume. The goal was to get the module to 68 inches (172 centimeters)
above its packed length before using the onboard tanks. (5/28)
What to Do If You Discover an Alien
Civilization (Source: Independent)
Some have argued that it's only a matter of time till we find alien
life – so we should get planning. Finding intelligent life beyond the
Earth is clearly likely to be one of the most shattering moments in the
history of our species. So if you’ve just discovered an alien
civilization, how should you go about breaking the news? This is a
momentous task, and I have been involved in developing some guidelines
for the scientists who are involved in searching for extraterrestrial
life.
If we ever do find signs of intelligent life, I don’t expect it to be a
message from an alien civilization or a landing party. It will probably
be something a little more prosaic, such as signs of artificial
pollution in the atmosphere of an exoplanet. It may even take the form
of enormous structures built in space to collect energy and provide
habitats. Click here.

Schafer Corp. Launches New Venture in
Commercial Space Situational Awareness (Source: Schafer)
Recognizing the rapid growth in commercial space satellites and the
need for technically accurate, timely, and relevant information about
an increasing number of objects in space, Schafer has formed a
Commercial Space Situational Awareness (CSSA) business unit. In
conjunction with the formation of this organization, Schafer has
appointed Colonel (Ret) Donald Greiman as Vice President and General
manager of this organization.
Together with former astronaut and retired Colonel Mark Brown, Greiman
has assembled a team of companies to compliment Schafer’s long-standing
experience in space situational awareness (SSA). The Schafer led team
is comprised of eight specialized companies who provide comprehensive
coverage of space from more than 85 widely distributed electro-optical,
radio frequency, and laser sensors covering space objects from LEO to
GEO. (5/25)
Russia Keeps Profiting from U.S.
Reliance on RD-180 Rocket Engine (Source: PJ Media)
The outcome of dueling versions of the National Defense Authorization
Act could determine how much the U.S. lines Russia's pockets before
what some lawmakers hope is a speedy transition to a domestically
produced rocket engine. The Kremlin's defense industrial complex stands
to gain a quarter billion to half a billion taxpayer dollars. Add that
to the billion they've already made from RD-180 engine sales to the
U.S.
And add on top of that questions about how much is directly going to
individuals sanctioned after Russia's invasion of Ukraine and
occupation of Crimea. “This is outrageous. And it is shameful. And it
is the height of hypocrisy, especially for my colleagues who claim to
care about the plight of Ukraine and the need to punish Russia for its
aggression," said John McCain. (5/27)
India Presses Ahead With Space
Ambitions (Source: VOA)
Indian scientists pronounced the testing of an indigenously developed
reusable space rocket this week, “Mission accomplished successfully.”
Those words have been heard increasingly in recent years from the
Indian Space Research Organization (ISRO) as it quietly presses ahead
with its space ambitions. Although a relative latecomer to the space
race, India’s space program has notched up some significant
technological breakthroughs and simultaneously developed a reputation
for being highly cost effective. (5/29)

Russia Deploys Another GLONASS-M
Spacecraft via Soyuz 2-1B Launch (Source: NasaSpaceFlight.com)
A Russian Soyuz 2-1B has launched the latest GLONASS-M global
navigation satellite from the Plesetsk Cosmodrome. Launch occurred on
Sunday. The Russian GLONASS Global Navigation Satellite System –
operated by the Russian Aerospace Defence Forces – is currently the
only global alternative to the American GPS fleet in operation that has
global coverage of comparable precision. (5/29)
Europe is currently building its Galileo system, while other countries
are building their own GPS systems – such as the Chinese BeiDou
Navigation Satellite constellation. Development of GLONASS began in the
Soviet Union in 1976. By the turn of the decade, GLONASS had achieved
100 percent coverage, with the full orbital constellation of 24
satellites operational in 2011. (5/29)
