Strange Star Has Serious Scientists
Talking About an Alien Megastructure (Source: Washington Post)
KIC 8462852 is a distant star with a very unusual flickering habit.
Something was making the star dim drastically every few years, and she
wasn’t sure what.
Boyajian wrote up a paper on possible explanations for the star’s
bizarre behavior, which was published recently in the Monthly Notes of
the Royals Astronomical Society. But she also sent her data to fellow
astronomer Jason Wright, a Penn State University researcher who helped
developed a protocol for seeking signs of unearthly civilization,
wondering what he would make of it.
To Wright, it looked like the kind of star he and his colleagues had
been waiting for. If none of the ordinary reasons for the star’s flux
quite seemed to fit, perhaps an extraordinary one was in order. Aliens.
Or, to be more specific, something built by aliens — a “swarm of
megastructures.” Click here.

Veto of DOD Bill Would Complicate
Phase-Out of Russian Engines (Source: USA Today)
Efforts to stop using Russian-made engines on rockets carrying U.S.
military satellites have run into trouble because of partisan battles
over Pentagon budgeting and the terrorist detention camp at Guantanamo
Bay.
Language to continue the phase-out of the RD-180 engines by the end of
the decade is part of a defense authorization bill that President Obama
has threatened to veto. His reasons: The bill also contains Republican
provisions that would prevent Obama from closing the prison camp in
Cuba and would try to sidestep automatic “sequestration” spending cuts
at the Pentagon. (10/14)
South Korea Seeks US Support in Space
Program (Source: Korea Times)
President Park Geun-hye visited NASA's Goddard Space Flight Center on
Thursday. Her visit to the U.S. agency's first space research
laboratory came 50 years after her father and former President Park
Chung-hee, who was keen on advancing science and space technologies,
toured NASA's Kennedy Space Center in Florida in 1965.
She vowed to step up efforts to advance cooperation with the United
States in the sector. "I hope cooperation between Korea and the U.S. in
lunar and space exploration will broaden and help the two countries
share space resources," she said. (10/15)
China Aims to Go Deeper into Space
(Source: Xinhua)
As China's exploration of the moon progresses, its space experts have
begun considering going deeper into the solar system - to Mars,
asteroids and Jupiter - and a manned deep-space mission. At a recent
conference on deep-space exploration in Harbin, capital of northeast
China's Heilongjiang Province, an official urged scientists and
technologists to have a pioneering spirit.
China should also strengthen international cooperation. "Exploring
space is a great undertaking for the whole of humankind, and China
should shoulder its responsibilities as a big country. Through
international cooperation, we can learn from each other and jointly
contribute," Liu said. (10/15)
Putin Delays First Launch, Raps
Officials, Sets Ambitious Goals for New Spaceport (Source:
Siberian Times)
It is Russia's biggest construction project, a new cosmodrome on the
eastern edge of Siberia, some 5,500 kilometers from Moscow. President
Vladimir Putin's visit on Wednesday confirmed the open secret that the
initial launch will be next year, in April at the earliest, and not in
December 2015 as originally planned.
He also insisted on his visit to the Far East of Russia that corruption
allegation against officials involved in the spaceport must be pursued
with vigour. But he made clear as the US announces its ambitious
program of space exploration that Russia intends to use Vostochny to
maximize Moscow's own plans. (10/15)
SpaceX Expects Return to Flight in
December (Source: Advanced Television)
The long-delayed return to flight of SpaceX’s Falcon rockets is likely
to happen in December, according to Lee Rosen, SpaceX’s VP/mission and
launch operations. The SpaceX Falcon-9 rocket exploded moments after
lift-off on June 28th and has been identified as being caused by a
failed strut on a high-pressure Helium tank which created the
catastrophic explosion.
A number of satellite owners have been patiently waiting for the past
four months for the rocket to be given the all clear and for launches
to re-commence. Top of the list is Luxembourg-based SES which is likely
to see its SES-9 launched on a slow journey to geo-stationary orbit,
and using a more powerful Falcon-9 ‘Heavy’ rocket. (10/15)
Jeb Bush: Newt Gingrich's Moon Colony
Idea was 'Cool' (Source: CNN)
When former House Speaker Newt Gingrich proposed the idea of forming
colonies on the moon during his 2012 presidential bid, he got a lot of
laughs. But not from Jeb Bush. The former Florida governor said
Wednesday that he actually liked the idea. Recalling the skeptical
responses to Gingrich's pitch, Bush said he remembered thinking,
"Really? I think it's pretty cool."
Bush, speaking before an aircraft at the McAuliffe-Shepard Discovery
Center in Concord, New Hampshire, called for ramping up the US space
program and blasted President Obama for cutting back. Bush, who
admitted he's biased about the space program because he's from Florida,
called for "more aspirational" goals and gave one woman a fist bump
when she told him she's from the space coast in his home state.
Those bigger goals, he added, could be feasible if the government
paired up with the private sector, praising entrepreneurs like SpaceX
CEO Elon Musk. "I mean what's wrong with having big aspirational goals?
It's not in the absence of taking care of the hungry or the poor. We're
a big country. We're a generous country. The benefits of this are far
more than people realize," Bush said. (10/15)
Air Force Sets Up New Launch Systems
Enterprise Directorate (Source: USAF SMC)
The Space and Missile Systems Center's newest directorate, the Launch
Systems Enterprise Directorate, began operations on Oct. 14. Under the
leadership of Dr. Claire Leon, the new directorate brings together the
Launch Systems Directorate and the Rocket Systems Launch Program (which
formerly fell under SMC's Advance Systems and Development Directorate
at Kirtland Air Force Base).
"Until today, the Air Force has procured and executed space launch
capabilities through two separate organizations within SMC - RSLP and
SMC/LR. This created the potential for ambiguity among our
stakeholders and a disconnect in our acquisition strategy," said Lt.
Gen. Samuel Greaves. "Today, we unify Air Force space launch
capabilities under one directorate to synchronize our acquisition
activities."
The new directorate's mission is to be the "guardian of assured access:
launching when and where the nation needs it." LE's vision
statement is to be the most respected and innovative spacelift team,
delivering mission success while enabling a robust U.S. launch
industry. (10/14)
At Least Two of Three NASA Microsat
Launchers Plan Florida Ops (Source: SPACErePORT)
Both Rocket Lab and Firefly say they plan to launch their new rockets
from Florida. And Virgin Galactic may too, since they won't be able to
launch into orbit from Spaceport America (and I suspect they are one of
the recent confidential recipients of a Florida relocation incentive
investment).
Rocket Lab will initially launch from New Zealand but plans to
eventually operate from the Cape Canaveral Spaceport, probably at
LC-39C. Firefly, meanwhile, has had plans to operate from a Texas
spaceport but now says they will conduct suborbital test flights from
Florida (again, probably at LC-39C). The NASA contract calls for one
launch from each of the three companies, costing $10M for Virgin
Galactic, $8M for Firefly, and $4.9M for Rocket Lab. (10/14)
Lockheed Martin Targets Up to Four
Commercial Atlas 5s Per Year (Source: SpaceFlight Now)
Lockheed Martin’s launch services team hopes to lure up to four
commercial customers per year to fly on ULA’s Atlas 5 booster as a
stream of U.S. government missions is forecast to dry up starting in
2017, according to Lockheed Martin’s rocket sales chief.
For the Atlas 5 marketing team, it represents a significant change
after being mired on the sidelines of the multibillion-dollar global
launch services market for a half-decade. The first fully commercial
Atlas 5 launch from Cape Canaveral in nearly five years took off Oct. 2
with Mexico’s Morelos 3 communications station.
“I go after customers aggressively all the time,” said Steve Skladanek,
president of Lockheed Martin Commercial Launch Services, in an
interview with Spaceflight Now. “There are a couple of customers who
have expressed a desire to launch in late 2016. We’re looking for ways
to create a new opportunity toward the end of 2016, working very
closely with ULA to create that capability.” (10/14)
The Rocket Man Who Wants To Beat the
Billionaires (Source: Popular Mechanics)
Dave Masten stares at his computer screen, finger poised over the mouse
button. He knows that opening this email, sent by DARPA, will change
his life. One way or the other. This email is the fulcrum of his
future. It is either an acceptance letter or a rejection letter for his
company's proposal to build what DARPA calls XS-1.
XS-1 is an experimental unmanned space plane that can fly ten times in
ten days, reaching a speed of Mach 10–plus and lifting payloads greater
than three thousand pounds to orbit, at a cost of no more than $5
million per flight.
Being accepted as one of the three competing contractors represents the
best shot that Dave Masten—perennial underdog, Silicon Valley refugee,
scrappy space-industry entrepreneur—will have to build a working
spacecraft. It would mean an immediate infusion of $3 million, with
more coming the next year. The final contract could be worth as much as
$140 million. Click here.

Three NASA Technologies That Could
Make a Mars Colony Possible (Source: CSM)
In the box office hit “The Martian,” Matt Damon plays an astronaut
stranded on Mars who manages to survive and even grow plants on the
barren planet. But that is nothing compared with what NASA really has
in mind for Earth’s planetary neighbor. NASA has plans for Mars to be
peppered with interconnected structures resembling a trailer park. Rows
and columns of housing units, laboratories, garages, and storage space,
all neatly organized.
A team of automated machines would assemble these structures, a squad
of autonomous humanoid robots would maintain them, and a platoon of
self-driving rovers would explore the area and collect resources.
Engineers at the Johnson Space Center and the Jet Propulsion Lab have
been developing scores of robotics technologies vital for a manned
mission to Mars. Click here.

California 8th Grader Designs Nail
Clipper for NASA (Source: San Francisco Chronicle)
If you think clipped fingernails strewn across your bathroom vanity are
a nuisance, imagine them hovering around you at all hours waiting to
get lodged in your eye or sucked into your lungs.
For astronauts that was a potential problem in need of a permanent
solution. Lucky for NASA, Ryan Beam of Scotts Valley knows his way
around a 3-D animation program. The 8th grader drew up plans for what
he calls ClipCatch, a small, printable box that hosts the clipping
process and traps the pesky nail fragments from escaping and
potentially harming people and equipment on the Space Station. (10/14)
SpaceShipTwo Bounces Back to Rubber
Fuel (Source: Space News)
Virgin Galactic is planning to return to a rubber-like fuel when it
resumes powered test flights of its SpaceShipTwo suborbital vehicle
based on the results of an ongoing series of tests of the spacecraft’s
hybrid rocket motor.
Virgin Galactic Chief Executive George Whitesides said the company had
carried out a series of full-duration test firings of the motor
recently, which used a rubber-like fuel formally known as
hydroxyl-terminated polybutadiene (HTPB).
Virgin Galactic originally planned to use HTPB fuel for the rocket
motor, which also uses liquid nitrous oxide propellant. However, in May
2014, the company announced it was switching to a polyamide fuel,
similar to nylon, citing improved performance. (10/14)
Orbital ATK's Next Cygnus ISS Cargo

Orbital ATK, one of two space companies with contracts to haul supplies
to and from the Space Station, will return to flight Dec. 3 from Cape
Canaveral after more than a year's stand-down because its last launch
blew up. On Wednesday NASA confirmed the launch date Wednesday, which
had long been proposed.
The launch will use an a United Launch Alliance Atlas V rocket carrying
an Orbital Cygnus spacecraft full of supplies for the space station. It
will be Orbital's fourth resupply launch, but the first from Cape
Canaveral Air Force Station. The launch time is set for 6 p.m., with a

Study Suggests Ceres Acts as Sponge

When asteroids crash into Ceres it acts as a super absorbent sponge
instead of sending most of the debris back into space, according to a
new study by Brown University. Researchers simulated collisions into
Ceres using the Vertical Gun Range at NASA’s Ames Research Center in
California and found most of the impact material stays put in the
impact crater. (10/14)
