Purple Bacteria on Earth Could Survive
Alien Light (Source: Space Daily)
Purple bacteria contain pigments that allow them to use sunlight as
their source of energy, hence their color. Small as they are, these
microbes can teach us a lot about life on Earth, because they have been
around longer than most other organisms on the planet. University of
Miami (UM) physicist Neil Johnson, who studies purple bacteria,
recently found that these organisms can also survive in the presence of
extreme alien light.
The findings show that the way in which light is received by the
bacteria can dictate the difference between life and death. Johnson,
head of the inter-disciplinary research group in complexity in the
College of Arts and Sciences at UM and his collaborators share their
findings in a paper titled "Extreme alien light allows survival of
terrestrial bacteria" published online in Nature's Scientific Reports.
The study reveals new possibilities for life on earth and elsewhere in
the universe. (7/28)
Parties Involved in Failed Proton-M
Launch to be Polygraphed (Source: Space Daily)
Those suspected of violating technological requirements which caused a
Proton-M rocket to crash recently will undergo polygraph tests
according to Russian Deputy Prime Minister Dmitry Rogozin. He also said
that the government is waiting for the final report from Roscosmos on
the Proton-M with three Glonass-M satellites that crashed shortly after
it was launched from the Baikonur Cosmodrome on July 2. (7/29)
Final Frontier Design Unveils New
Space Suit on Capitol Hill (Source: Space Daily)
A Brooklyn, NY, based space company Final Frontier Design (FFD) has
unveiled their new "3G" space suit at a NASA event on Capitol Hill. FFD
was chosen by NASA to represent small businesses at their "Tech Day on
the Hill", attended by 16 members of Congress and over 500 staff and
guests, including NASA's Administrator, Charlie Bolden.
The 3G suit, a full pressure IVA space suit, was designed expressly for
the commercial space industry, both suborbital and orbital, and is
safe, comfortable, lightweight, and inexpensive. It is made for
operation at +5 PSI, is built for flight certification, and weighs in
at less than 15 pounds. The 3G suit includes a host of unique and
original features. Click here.

Starburst Wind Keeps Galaxies Thin
(Source: Space Daily)
with its slightly askew orientation - offers astronomers an excellent
view of the star formation clusters near the galaxy's center, clusters
that turn out to be the point of departure for material being pushed
from the galaxy. Unlike humans, galaxies don't have an obesity problem.
In fact there are far fewer galaxies at the most massive end of the
galactic scale than expected and scientists have long sought to explain
why.
A new, UMD-led study published in the journal Nature suggests that one
answer lies in a kind of feast and fast sequence through which large
galaxies can keep their mass down. Galaxies become more massive by
'consuming' vast clouds of gas and turning them into new stars. The new
study shows in unprecedented detail how a burst of star formation in a
galaxy can blow most of the remaining star-building gas out to the edge
of the galaxy, resulting in a long period of starvation during which
few new stars are produced. (7/28)
NASA Spacecraft Find "Particle
Accelerator" in Van Allen Belts (Source: Space Today)
Twin NASA spacecraft launched last year have helped scientists
determine that charged particles in the Van Allen belts circling the
Earth are accelerated from within the belts. In a paper published in
the latest issue of Science, scientists reported on their ability to
track charged particles in the belts using the two Van Allen Probes
spacecraft in an effort to identify the source of the particles'
acceleration.
During one event in October, the probes showed the source of the
accelerated particles was in the middle of the belt, extending inward
and outward, and not from the outside in. That would be explained by a
local source of energy within the belts accelerating the particles,
according to scientists. (7/27)
Progress Launches, Docks with ISS
(Source: Space Today)
A Progress cargo spacecraft docked with the International Space Station
Saturday night less than six hours after its launch from Kazakhstan. A
Soyuz rocket carrying the Progress M-20M spacecraft lifted off form the
Baikonur Cosmodrome at 4:45 pm EDT Saturday. The spacecraft, flying an
accelerated four-orbit approach to the station, docked with the
station's Pirs module at 10:26 pm EDT Saturday. The spacecraft carries
more than 2.5 metric tons of supplies and equipment for the station,
including tools to help repair a spacesuit that suffered a water leak
during a spacewalk earlier this month. (7/28)

The cargo ship is loaded with nearly 3 tons of food, fuel, hardware and
science experiment equipment for the six-person crew of the station's
Expedition 36 mission. Among its cargo is a set of tools intended to
help the astronauts investigate and patch up the spacesuit that
malfunctioned during a July 16 spacewalk outside the orbiting
laboratory. (7/27)
ULA and Ball Aerospace Student Launch
Takes STEM to New Heights (Source: ULA)
High-power sport rockets carried payloads thousands of feet above the
plains of Pueblo, Colo., today at the United Launch Alliance (ULA) and
Ball Aerospace & Technologies Corp. Student Rocket Launch. The
event marked the culmination of an experience designed to simulate a
real-life launch campaign and encourage students to pursue careers in
science, technology, engineering and math (STEM).
The launch featured three high-power sport rockets built by interns at
ULA, including the Future – the largest rocket to launch in Colorado.
Ball interns created the five largest payloads (onboard
experiments/instruments), and K-12 students from Colorado and Alabama
created 12 additional payloads. (7/27)

Intrepid Museum's SpaceFest (Source: Space.com)
The Intrepid Sea, Air and Space Museum was bustling early Friday (July
26), as hundreds of visitors waited patiently to take part in the
second-annual SpaceFest celebration aboard the converted aircraft
carrier on the western edge of Manhattan. The Intrepid is hosting the
four-day space-themed event to promote science and exploration, and to
showcase the museum's most famous artifact: the space shuttle
Enterprise. (7/27)
Range's Duties Can Evolve Without
Sacrificing Safety (Source: Florida Today)
The Eastern Range’s regulatory authority over scheduling, safety and
other aspects of every launch vehicle lifting off from Cape Canaveral
Air Force Station and Kennedy Space Center has long been pointed at as
slowing down advancement and innovation at the spaceport. Smaller,
private operators in particular have grumbled that more progress could
be made toward modernizing launch vehicles and lowering the cost of
space flight if it were not for the over-reaching regulatory arm of
“the range.”
Often, “range safety” gets talked about as though they were some
mysterious force lording over space flight operations off the east
coast. There’s always plenty of debate about whether the range, and the
overall bureaucratic process of getting approved to fly out of the
Cape, is an awful burden on companies or a necessary safeguard. The
truth is, it’s a little of both.
The management of some of the tasks and operation of some of the
tracking assets now handled by the range could be overseen by a
quasi-private spaceport operator or the individual organizations
launching a mission. That kind of modified system is being examined now
by the Air Force, FAA and others. But there is a line that needs to be
drawn at safety-related decisions and, hopefully, the ongoing
discussions about a future version of the range will result in
protecting some indepedent authority for those kinds of calls. Click here.
