Key to Future Military Satcomm (Source: Space News)
The future of military satellite communications will involve more
international and commercial partnerships, a Pentagon official said
Tuesday. Winston Beauchamp, the U.S. Air Force deputy undersecretary
for space, said greater use of commercial services, as well as
interoperability built into ground equipment, will make it harder for
future adversaries to attempt to disrupt communications. The Air Force
has been taking steps towards greater use of commercial capabilities
through a series of "Pathfinder" programs, but they have encountered
some legal obstacles. (12/13)

Turkey Plans Space Agency, More
Satellites (Source: Spacewatch Middle East)
As Turkey seeks to expand its satellite fleet, the country is
struggling to establish a civil space agency. The Space Agency of
Turkey is intended to be a civilian space agency modeled after those in
many other nations, but legislation establishing it has stalled because
of disputes about how the military and civilian government will share
responsibilities.
The country's newest satellite, the Göktürk-1 imaging satellite,
launched last week, and the country has plans for additional
communications and Earth observation satellites. Turkey, though, is
also facing workforce issues, exacerbated by July's coup attempt and
subsequent dismissal of many Air Force officers, including some with

Declassified spysat images from the Cold War era are helping scientists
monitor changes in the Himalayas. Earth scientists used images
collected by the now-declassified HEXAGON program in the 1970s and
1980s to study the retreat of glaciers in the Himalayas, comparing
those images with more recent images by Earth science missions. Access
to those historical images, scientists said, has allowed them to better
quantify the rate at which the glaciers are melting. (12/13)

Magnetic Stars Could Have Created
LIGO’s Massive Black Holes (Source: Science News)
To create a heavy black hole, it might help to start with a massive
magnetic star. Strong magnetic fields could help stem the flow of gas
from a heavyweight star, leaving behind enough material to form hefty
black holes, a new study suggests. A pair of such magnetic stars could
be responsible for giving birth to the black hole duo that created
recently detected gravitational waves, researchers report.
The shake-up in spacetime that was picked up the Advanced Laser
Interferometric Gravitational-Wave Observatory, or LIGO, in 2015 came
from a collision between two black holes weighing about 29 and 36 times
the mass of the sun. Such plump black holes were surprising. The
creation of a big black hole requires the explosive death of a
gargantuan star. But weighty stars are so bright that the light blows
gas into space.
“These massive stars can lose up to half their mass to their dense
stellar winds,” says study coauthor Véronique Petit, an astrophysicist
at Florida Institute of Technology in Melbourne. That leaves only
enough mass to make a more modest black hole. (12/14)
Space Entertainment Startup ALE Raises

Shipwrecks Off Cape Canaveral Hint at
Alternative Past for the State (Source: AFP)
Treasure hunters have apparently found the 500-year-old remains of a
naval expedition led by a colonizer who could have changed Florida's
history, making it French-speaking at least for a while. The big
question is if the shipwreck is that of "La Trinite," the 32-gun
flagship of a fleet led by Jean Ribault, a French navigator who tried
to establish a Protestant colony in the southeast US under orders from
King Charles IX. They probably are, say authorities in Florida, the
French government and independent archeologists.
"If it turns out to be 'La Trinite,' it is the most important,
historically and archaeologically, the most important shipwreck ever
found in North America," said John deBry. All indications are that the
shipwreck found is the real thing. The artifacts found at the site off
Cape Canaveral include three bronze cannons with markings from the
reign of King Henri II, who ruled right before Charles IX; and a stone
monument with the French coat of arms that was to be used to claim the
new territory.
In 1565, Ribault set sail from Fort Caroline (now Jacksonville) to
attack his arch-enemy, the Spaniard Pedro Menendez de Aviles, who had
been sent to Florida by King Philip of Spain to thwart French plans to
set up a colony. But Ribault got caught in a hurricane, which destroyed
"La Trinite" and three other galleons and ended French dreams of
claiming Florida. Editor's

after the comprehensive search for pieces of Challenger and other

“Global Temperatures Plunge. Icy Silence from Climate Alarmists.”
(There is always some drop in temperature when El Niño transitions into
La Niña—but there has been no anomalous plunge.) Under normal
circumstances, this tweet wouldn’t be so surprising: Lamar Smith, the
chair of the committee since 2013, is a well-known climate-change

NASA Presses Ahead with Asteroid
Mission Despite ESA Funding Decision (Source: Space News)
Scientists involved with a proposed NASA mission to a near Earth
asteroid say their work is not affected, for now, by a decision by the
European Space Agency earlier this month not to fund a companion
spacecraft. NASA and ESA had been cooperating on a joint effort known
as the Asteroid Impact and Deflection Assessment (AIDA). That mission
concept involved two spacecraft: the Double Asteroid Redirection Test
(DART), to be developed by NASA, and ESA’s Asteroid Impact Mission
(AIM).
The AIDA concept involved sending AIM to Didymos, a near Earth asteroid
about 800 meters in diameter that has a moonlet, informally known as
Didymoon, about 150 meters across orbiting it. AIM, launched in October
2020 and arriving in May 2022, would study Didymos and its moonlet
prior to the arrival of DART. DART, launched in December 2020 and
powered by a solar electric propulsion system, would then collide with
Didymoon in October 2022. AIM would observe the collision and its
aftermath, including measuring the deflection in the moonlet’s orbit
caused by the collision.
Even if ESA is not able to revive AIM, scientists said that DART alone
can still carry out its mission to demonstrate kinetic impacts. That
would require observations by ground-based telescopes to monitor the
deflection in Didymoon’s orbit after the impact. “DART was designed to
be independent of AIM,” said Joseph Nuth, senior scientist for
primitive bodies at NASA’s Goddard Space Flight Center, at the AGU
meeting Dec. 12. “AIM makes it better, but all the information can be
derived from ground-based instruments.” (12/13)

NASA Will Limp Through a Trump
Presidency (Source: Inverse)
Perhaps the most discouraging addition to the NASA transition team is
Greg Autry, an University of Southern California professor of
entrepreneurship, who has been bullish about the potential for the
commercial space industry to usher in a new era of space exploration
despite how many exploding Falcon 9 rockets rain down on Earth. Autry
has in particularly derided the Space Launch System, the rocketry
system NASA is building that will help launch bigger payloads into deep
space, in anticipation of a crewed mission to Mars.
“We will discontinue spending on Space Launch System, a giant
government rocket, lacking both innovation and a mission,” he writes in
an op-ed on Forbes in October. “While SLS has consumed the largest
single piece of NASA’s budget for years, private sector operators like
SpaceX and Blue Origin have leapfrogged it with more efficient,
reusable boosters.”
Another addition to the transition team is Steve Cook, the former head
of the Ares 1 and Ares 5 rocket programs (scrapped by President Obama
in favor of SLS). Cook has since worked in rocket design in the private
sector, and might also be more keen to allow the private sector to
fulfill NASA’s rocket needs. (12/12)
NASA Will Take 2 Years to Complete
Investigation into 2015 Falcon 9 Failure (Source: Parabolic Arc)
"While the [investigation] report is important in providing NASA
historical data of the mishap, the accident involved a version of the
Falcon 9 rocket that is no longer in use. Furthermore, while the public
summary itself may only be a few pages, the complete report is expected
to exceed several hundred pages of highly detailed and technical
information restricted by [ITAR] and company-sensitive proprietary
information. As a result, NASA anticipates its internal report and
public summary will be finalized in the summer 2017.
That is a rather long time, even for a sometimes pokey government
agency investigating the failure of a booster variant no longer in use.
It’s an especially long period given what SpaceX’s separate
investigation concluded was the cause of the accident. According to a
NASA Office of Inspector General (IG) report, SpaceX’s accident
investigation into Falcon 9’s in-flight failure found the most probable
cause for the mishap was a strut assembly failure in the rocket’s
second stage. (12/13)
Why Are Scientists Shooting Stem Cells
Into Space? (Source: Science)
The near-weightless conditions of flying in space can wreak havoc on
your hairdo and your sense of direction. And as it turns out, they can
also do some pretty weird things to cells in a dish. During a session
here yesterday at the World Stem Cell Summit (WSCS), an annual
gathering of scientists and advocates organized by the nonprofit
Regenerative Medicine Foundation, researchers described their forays
into stem cell research in microgravity.
It’s possible to simulate weightless conditions on Earth, but there’s
one way to get the real thing: Send cells on a 400-kilometer vertical
journey to a U.S. national lab stationed on the International Space
Station (ISS). Here are three questions scientists hope to answer by
