LIGO Scientists Win Nobel
Physics Prize (Source: New York Times)
Three scientists won the Nobel Prize in Physics this morning for their
discovery of gravitational waves. The prize will be shared by Rainer
Weiss of MIT and Kip Thorne and Barry Barish, both of Caltech, for
their work leading the development of the Laser Interferometer
Gravitational-wave Observatory (LIGO). Scientists using LIGO announced
last year the discovery of the first graviational wave, a spacetime
phenomenon predicted by Einstein's theory of general relativity and
created by two colliding back holes. LIGO has detected several more
gravitational waves since. A fourth person involved in the development
of LIGO, Ron Drever, passed away earlier this year. (10/3)
ISS Partners Want Clarity
on Lab's Future (Source: Space News)
International Space Station partners are hoping to get clarity on the
long-term future of the station sooner rather than later. During a
panel session at last week's International Astronautical Congress in
Australia, NASA's Bll Gerstenmaier said he hoped that the the
partnership would reach a decision on what to do with the ISS post-2024
within the next two years, so that investors considering commercial
partnerships involving the station have time to earn a return on their
investment. That view was shared by some other representatives of ISS
partners on the panel. Gerstenmaier rejected setting a firm date for
the end of the station, seeking instead to develop criteria for
transitioning from the ISS to other platforms. (10/3)
Spaceflight Wins NASA
Secondary Payloads Contract (Source: Geekwire)
Spaceflight has won a NASA contract to provide secondary payload
services. The three-year contract, with a maximum value of $5.48
million, covers the integration of 24 "U-class" payloads in 2018 with
options for a similar number in both 2019 and 2020. Such payloads are
typically university-built cubesats that NASA has arranged to fly on
its own missions. (10/3)
Methane Bursts Could Have
Allowed Martian Lakes (Source: New Scientist)
Bursts of methane could have allowed Mars to keep liquid water on its
surface. A new study suggests that "explosive burps" of methane, a
powerful greenhouse gas, from ice deposits could have warmed the planet
enough for brief periods to allow liquid water to exist on its surface.
The methane would have worked in concert with carbon dioxide already in
the atmosphere to provide the extra warming, but some studies suggest
the early Martian atmosphere had less carbon dioxide than previously
thought. (10/3)
Freon Not a Reliable
Indicator of Life Out There (Source: Cosmos)
Freon may not be the tracer of life beyond the solar system that some
scientists originally thought. A new study found evidence of the
compound in a newly formed star system that is too young for life to
exist. Scientists had previously speculated that Freon might be a good
tracer of biological activity, since it is made through biological and
industrial processes, but its discovery in a new star system means that
the discovery of that compound alone is not evidence of life. (10/3)
UK Scientist Wins Reality
TV Astronaut Nod (Source: BBC)
A British scientist now has an unusual endorsement in her bid to become
an astronaut: winning a reality TV show. Suzie Imber, a professor of
planetary science at the University of Leicester, won a BBC Two show
Sunday titled "Astronauts: Do you have what it takes?" On the show, she
and 11 other contestants went through a series of challenges overseen
by former Canadian astronaut Chris Hadfield. By winning the show, Imber
gets a "recommendation" to join ESA's astronaut corps, but with no
guarantee of a future selection. (10/3)

Russia to Decide on
Super-Heavy Space Rocket Soon (Source: Tass)
Russia may shortly make a decision on developing a super-heavy carrier
rocket, Chief Designer of Energiya Rocket and Space Corporation Yevgeny
Mikrin said. "Now a decision on a medium-range rocket has been made and
we hope that soon a decision on a super-heavy carrier will be passed,"
the chief designer said. Russia’s Moon exploration program envisages
creating a near-Moon station. The Federatsiya new piloted spacecraft is
planned to be launched to the Moon. The new super-heavy carrier rocket
is needed for the full-fledged implementation of the lunar program, he
noted. As the chief designer said, "a new module weighing up to seven
tonnes can be launched [to the Moon] with the help of an Angara or
Proton carrier," he said. (10/2)
The Mysterious Bright
Spots on Ceres May Have a Common Origin (Source: New
Scientist)
The bright spots of Ceres, a dwarf planet in the main asteroid belt,
have provoked curiosity and speculation ever since NASA’s Dawn
spacecraft spotted them in 2015. Now it seems they might all have
formed the same way, even though they are made of different materials.
Ceres is speckled with hundreds of bright splotches. An international
team led by Ernesto Palomba at the National Institute for Astrophysics
in Rome is analysing the light reflected by them – as observed by Dawn,
presently in orbit around Ceres – to identify any differences between
them.
“The bright spots are only bright relative to Ceres’ already-dark
surface,” says Nathanial Stein, a collaborator at the California
Institute of Technology. “If you saw those spots on Earth or even on
[the asteroid] Vesta you would consider them to be dark spots.” While
the biggest and brightest spots are in Occator crater, more exist
elsewhere on the dwarf planet. “Almost all of them are associated with
impact craters,” says Stein. The team found 90 per cent of the bright
spots are in craters or are debris ejected from a crater.
Researchers theorise that the spots are the result of the heat of an
impact melting subsurface materials, which then well up to the surface
to create the bright spots. Most of the spots are made from the same
basic material as the rest of Ceres’s surface: calcium or magnesium
carbonates mixed with ammonia-rich clays. But a handful of the spots in
the youngest craters – including the exceptionally bright spots in
Occator crater – are made of sodium carbonates without nearly as much
ammonium clay. (10/2)
Has NASA asked SpaceX to
Not Launch Falcon Heavy From LC-39A? (Source: SpaceFlight
Insider)
A recent post on Reddit has suggested that SpaceX had been asked by
NASA to not launch its Falcon Heavy rocket from the historic Launch
Complex 39A at the space agency’s Kennedy Space Center in Florida. As
is so often the case on the Internet, unconfirmed rumors can often
spread misinformation that is then taken as fact. Is there any
credibility to this rumor?
SpaceFlight Insider reached out to both SpaceX and NASA about the
veracity of this statement and received responses from both of these
organizations suggesting that this rumor does not appear to be based on
fact. NASA directed us to SpaceX as they are the manufacturer of the
Falcon Heavy and SpaceX provided SpaceFlight Insider with the
following: We are targeting no earlier than the end of 2017 for Falcon
Heavy’s inaugural flight from Launch Complex 39A in Florida.
Other sources, who requested anonymity, have told SpaceFlight Insider
that SpaceX is planning to use LC-39A as a site to launch the Falcon
Heavy from, with Canaveral’s Space Launch Complex 40 handling some
launches of their highly successful Falcon 9 – all this, apparently,
refutes the above statement. SpaceX also has launch facilities at
Vandenberg Air Force Base in California and is having a launch site
developed in Boca Chica, Texas. (10/2)
