Scientists Have Detected Gravitational
Waves for the Second Time (Source: The Verge)
Scientists with the LIGO collaboration claim they have once again
detected gravitational waves — the ripples in space-time produced by
objects moving throughout the Universe. It’s the second time these
researchers have picked up gravitational wave signals, after becoming
the first team in history to do so earlier this year.
This second detection boosts the likelihood that LIGO is truly
measuring waves and not something else. "Seeing a second loud signal
like this means the first detection wasn’t just luck," said Duncan
Brown, a LIGO researcher and a professor of physics at Syracuse
University. These two wave signals also occurred within just a few
months of each other, hinting that these detections may happen pretty
frequently for LIGO moving forward.
As with the original finding, these waves came from the merger of two
black holes — super dense objects that form when a star collapses and
dies. During the merger, these black holes rapidly spun around each
other several times a second, before joining together into a single
extra-dense object. The whole process generated massive gravitational
waves that rippled outward at the speed of light. (6/15)
Students and Educators Develop Their
Rocket Skills at NASA Wallops (Source: SpaceRef)
During Rocket Week, held from June 18-24 at NASA’s Wallops Flight
Facility in Virginia, nearly 200 university and community college
students and instructors from across the country will build and fly
experiments on a NASA suborbital rocket through the RockOn! and
RockSat-C programs. Another 20 high school educators from the eastern
United States will examine how to apply rocketry basics into their
curriculum through the Wallops Rocket Academy for Teachers (WRATs).

ESA Reaffirms ExoMars Plan
(Source: BBC)
The European Space Agency has reaffirmed its support for a Mars rover
mission despite launch delays. The ESA Council, meeting in Paris this
week, backed plans to launch the ExoMars lander and rover mission in
2020, two years later than previously planned. That support includes
the immediate release of 77 million euros ($87 million) in funds from
ESA's four largest member states into the project to ensure work on the
mission is not further delayed. ESA officials said the rover mission
now has a "realistic technical schedule" to support that 2020 launch.

ULA Resolves Atlas Engine Anomaly
Issue Ahead of June 24 Launch (Source: ULA)
ULA says it has identified and resolved the problem on the previous
Atlas 5 launch. In a statement Wednesday, the company said an
"unexpected shift in fuel pressure differential" across a mixture ratio
control valve in the RD-180 engine, nearly four minutes after liftoff,
caused the engine to run oxidizer-rich. That depleted the supply of
liquid oxygen and shut down the engine prematurely, even though there
was still "significant fuel" left on the first stage.
ULA said the engine supplier, NPO Energomash, has made a minor change
to the valve to prevent that problem from taking place again, and that
change has been verified in hot-fire tests. The Atlas 5 is set to
return to flight June 24 with the launch of the MUOS 5 military
communications satellite. (6/16)
Bezos Likes NASA Prizes Approach
(Source: Space News)
Blue Origin founder Jeff Bezos said he thinks NASA should pursue large
prize competitions and "gigantic" technology development efforts.
Bezos, interviewed during a presentation at the National Air and Space
Museum this week, said that if the next administration asked him for
space policy advice, he would recommend NASA offer large prizes for
efforts currently being done in-house by NASA, like Mars sample return.
NASA should then pursue very difficult technology efforts, like an
in-space nuclear reactor, he said. (6/15)
JAXA Officials Take Pay Cut for Hitomi
Failure (Source: JAXA)
Three top JAXA officials will take a temporary pay cut in response to
the failure of the Hitomi mission. The agency announced Wednesday the
three, including JAXA President Naoki Okumura, would take a 10 percent
pay cut for four months. Hitomi, an x-ray astronomy mission launched in
February, failed in March after a series of problems, with human error
playing a factor. (6/15)
Cygnus Fire Experiment Succeeds
(NASA)
An experiment to create the largest controlled fire in space was a
success. NASA said Wednesday the Saffire experiment, included in the
Cygnus spacecraft that departed from the station Tuesday, burned a
sample material nearly one meter long in an enclosed space within the
spacecraft. Images and data from Saffire will be returned to Earth
before the Cygnus reenters next week. Two more Saffire experiments are
planned for future Cygnus missions. (6/15)

SETI Gets an Upgrade (Source:
Air & Space)
For decades, astronomers have been listening for messages sent to us—a
“Hello, is anyone out there?” signal from intelligent aliens. But now
Dan Werthimer's team at the University of California at Berkeley is
conducting the first search for communities on other worlds that are
speaking to one another—between planets and even across star systems.
And to do it, he has two of the world’s largest radio telescopes and
support from a planet‑hunting optical telescope.
Thanks to a new initiative announced last July, Werthimer’s team will
begin searching for extraterrestrial civilizations, using instruments
with greater sensitivity and scanning across a wider range of
frequencies than any SETI (search for extraterrestrial intelligence)
project to date. Called Breakthrough Listen, it began earlier this year
and will continue for a decade at a price tag of $100 million. “It’s a
lot of money, a lot of telescope time,” says Werthimer. “We’ll be able
to look at a hundred billion radio channels simultaneously. (6/15)
The Universe is Ringing
(Source: Air & Space)
Practically every action makes gravitational waves—you can create them
by waving your arms—but it takes serious astronomical doings to
generate anything powerful enough to be detected. Earth orbiting the
sun produces them, but they are low energy (which is good for the
long-term stability of our solar system); two pulsars, the
ultra-compact remnants of massive stars, locked in binary orbit produce
far more substantial waves.
As those bodies sweep around each other, they compress and expand the
structure of space-time itself, creating a disturbance that travels out
at the speed of light.Conceived as a joint project between NASA and the
European Space Agency, LISA was originally projected to launch between
2012 and 2016. However, NASA withdrew participation in 2011, leaving
the very expensive project entirely up to ESA. By cutting back on the
ambition a bit, the project survived as European LISA, or eLISA, but
now the launch date is 2034, which is far enough in the future to make
any forecasts doubtful. (6/15)
SpaceX's Banner Year Continues with
Dual ABS Launch, Failed Landing (Source: SpaceFlight Insider)
With the year halfway over, SpaceX conducted its sixth launch of the
year with a “Full Thrust” Falcon 9 taking to the skies with the ABS /
Eutelsat-2 satellites. SpaceX had already conducted five missions this
year, all of them successful. Things did not go as planned with the
rocket’s first stage landing. “Maybe hardest impact to date,” according
to Elon Musk via Twitter. Upon impact the stage encountered a "Rapid
Unscheduled Disassembly.” (6/15)

GOP Candidate Would Drop Out if Rubio Runs for Senate Seat (Source:
Daily Beast)
Rep. David Jolly, one of four top Republican candidates for Senate in
Florida, says he would drop out of the race if Marco Rubio changes his
mind about running for re-election for the seat. Rubio, a former 2016
presidential contender, said during the campaign he would not seek
re-election for his Senate seat. However, in recent weeks Rubio's
fellow Republican senators—including presumptive GOP presidential
nominee Donald Trump—have encouraged him to reconsider.
Editor's Note:
Rubio had plans to visit the Cape Canaveral Spaceport on Friday to meet with
space industry leaders, but the visit was postponed due to the Orlando shooting. Senator Rubio, like Sen. Bill Nelson, has been
an advocate for the state's space interests in Washington. (6/15)
