The Most Vulnerable NASA Missions
Under Trump (Source: The Atlantic)
About a week before the presidential election, NASA invited reporters
to its facility in Greenbelt, Maryland to look at the observatory it
hopes to launch in two years, to a point far beyond Hubble’s orbit,
where it will continue that telescope’s search for distant stars and
galaxies. Charlie Bolden, the head of the space agency, took questions,
including one from a reporter for The Guardian, who asked Bolden
whether the program was safe, regardless of the election’s outcome.
Bolden cracked up immediately, and the rest of the room followed. He
explained that most of the billions of dollars in funding the James
Webb Space Telescope received was spent early on in its years-long
development. He wasn’t worried now, “but I think anybody would be crazy
to tell you that anything survives over a transition." Bolden, along
with many in the room, believed back then what the polls and the
pundits did: Donald Trump wasn’t going to be elected president. Click here.

Beyond Ka: Supporting Future
Telecommunications (Source: Via Satellite)
The satellite industry is developing at a rapid rate. New applications
are emerging all the time. Due to the fact that satellite can be used
for so many applications, such as broadcasting, mapping, meteorology,
Earth observation and much more, the rapid increase in use over recent
years has resulted in a serious shortage of bandwidth availability in
the lower frequency bands.
The industry has been talking about this congestion for quite some time
now. We have seen the industry move into new bands, from C to Ku and
from Ku to Ka. The move to Ka band is expected to relieve the pressure
on available bandwidth as there will be much more available. However,
with demand growing for higher throughput, and the advent of
Non-Geostationary Orbit (NGSO) constellations, the industry is
considering the future. Now, the time has come to assess the potential
that lies in other bands that can help support the growing demand for
applications that require high throughput today and in the future.

NASA Selects SwRI Mission To Jupiter’s
Trojan Asteroids (Source: Colorado Space News)
NASA has selected a Southwest Research Institute mission to study
primitive asteroids orbiting near Jupiter that could give insights into
the origins of the solar system. The mission, known as Lucy, will
proceed to mission formulation, with the goal of launching in October
2021.
Lucy, a robotic spacecraft, is slated to arrive at its first
destination, a main belt asteroid, in 2025. From 2027 to 2033, Lucy
will explore six Jupiter Trojan asteroids. These asteroids are trapped
by Jupiter’s gravity in two swarms that share the planet’s orbit, one
leading and one trailing Jupiter in its 12-year circuit around the sun.
The Trojans are thought to be relics of a much earlier era in the
history of the solar system, and may have formed far beyond Jupiter’s
current orbit. (1/4)
NASA Drives Vision of Air Traffic
Management for Drones (Source AIN)
Quite apart from the drone the neighborhood kid sails over the
hedgerow, the FAA and industry observers expect that hundreds of
thousands of small, commercial unmanned aircraft systems (UAS) will
eventually seek access to the nation’s airspace. For some four years
now, the NASA-led UAS Traffic Management (UTM) research effort has
worked to shape the rules and capabilities of this coming low-altitude
ecosystem.
Spearheaded by NASA senior engineer for air transportation systems
Parimal Kopardekar—better known as “P.K.”—the UTM concept of a
low-altitude airspace management system for drones dates to 2012. The
space agency provided seed money for the effort initially, then
established it as a program with $15.6 million in funding in Fiscal
Year 2015. Some 120 UAS manufacturers, software system developers,
communications companies and other entities answered a NASA
solicitation to collaborate on the system development; a number have
formalized their participation through Space Act Agreements. NASA
listed 65 “UTM Partners” as of September.
The space agency and the FAA have formed a joint research transition
team, and plans call for transferring UTM technology to the FAA by
2019. (12/22)
The Martian RV (Source: Air
& Space)
Just as the fictional Mark Watney depended on his habitat module to
survive the extreme Martian environment, future Mars astronauts will
need a shelter that not only protects them from unpredictable weather
but also offers some of the psychological comfort of home.
Students in the Human Factors Psychology program at Embry-Riddle
Aeronautical University’s Daytona Beach, Florida, campus have just the
solution: a refurbished 1976 Airstream trailer. Led by faculty advisor
Jason Kring, the students have transformed their Airstream—the same
kind of vehicle used by NASA decades ago to quarantine returning Apollo
astronauts—into the Mobile Extreme Environment Research Station, or
MEERS.
“I’m just really fascinated by how you could get six people on a
roundtrip to Mars, how you would design the vehicle, how you would
train them, how you select the crew,” explains Kring, an associate
professor of Human Factors. “That’s where the MEERS project came from.
It’s a way to have our students have a test bed to look at some of
these issues.” Click here.

Gotcha: Fast Radio Burst's Home Nabbed
(Source: Science News)
A mysterious, recurring blast of cosmic radio waves finally has a home
address. For the first time, astronomers have definitively traced a
fast radio burst back to its source: a faint galaxy about 2.5 billion
light-years away. The finding confirms a decade-long suspicion that
these outbursts originate well outside our galaxy, although the mystery
as to what’s causing them remains unsolved.
“Now with the first proven distance, we can see how remote and how
bright the source must be,” Sarah Burke-Spolaor, an astrophysicist at
West Virginia University, said January 4 at a meeting of the American
Astronomical Society. For roughly five milliseconds, the burst
outshined all the stars in its own galaxy and rivaled the luminosity of
blazing disks of gas that swirl around supermassive black holes, said
Burke-Spolaor, one of the researchers involved with the project. (1/4)
Mars Should Have Loads More Water – So
Where Has it All Gone? (Source: New Scientist)
Mars has a real water shortage. It seems we have either misunderstood
what its early years were like – or vast amounts of water are hiding
beneath its surface. A lot of evidence points towards Mars being warm
and wet early in its history; features that look like rivers, lakes and
outflows have been spotted both from orbit and by rovers on the
surface, and a lot of the planet’s minerals contain water.
So where did all this water go? The Mars Atmosphere and Volatile
Evolution (MAVEN) spacecraft was sent to find the answer. Since its
arrival at Mars in 2014, it has been measuring how much atmosphere Mars
is losing to space. From that, we can figure out how much it had in the
past. Click here.

NASA Sets Sights on Asteroid
Exploration (Source: Nature)
NASA will send two spacecraft to explore asteroids in the hopes of
revealing new information about the Solar System's origins. Psyche will
journey to the metallic heart of a failed planet and Lucy will
investigate the Trojan asteroids around Jupiter.
The missions, announced 4 January, are part of NASA's Discovery
programme for planetary exploration. They were shortlisted by NASA in
September 2015 and survived a final cut that eliminated two proposed
missions to Venus — which has not seen a US planetary mission since
Magellan launched in 1989. (1/4)

Don't Take Aim at Space Florida
(Source: Sun Sentinel)
Taking a page from the president-elect's playbook, new Florida House
Speaker Richard Corcoran is shaking up the status quo in state
government. That includes threatening to defund two economic
development agencies, Enterprise Florida and Visit Florida, because
they don't match his vision for limited government. Corcoran's crusade
has also raised questions about the future of Space Florida, another
economic development agency. But the speaker's gripes with the other
two agencies don't apply to Space Florida. Click here.

Man Sues NASA for Alleged Mistreatment
(Source: KTRK)
Lealum Mulugeta has always had a passion for space flight. "I arrived
at NASA with the hopes of pursuing my dream," he said. When he got a
job working for NASA through contractor Universities Space Research
Association, he was over the moon. That soon changed.
"There were certain things said to me that were not proper. One of the
civil servants I worked under told me I was practically his slave and
he could abuse me all he wants," he said. Mulugeta, a native Ethiopian
who emigrated to Canada as a child before coming to the United States
to work for NASA, said at first he didn't want to think it was
discrimination. (1/3)
Case for a Philippine Space Agency:
Space Tech Needed for Life in the Islands (Source: The Standard)
Senator Loren Legarda proposed the creation of a Philippine Space
Agency not to send hungry Filipino astronauts to space but to focus on
applications and technologies that will enhance national security and
help Filipinos in their daily lives. In filing Senate Bill No. 1259,
Legarda proposed the creation of the PSA and a National Space
Development and Utilization Policy which will serve as the country’s
primary strategic roadmap for space development.
She said this will also embody the country’s goal of becoming a
space-capable and space-faring nation within the next decade. “It is
unfortunate that due to lack of local support to this field, many of
our globally-competitive Filipino space scientists have instead opted
to serve in space agencies abroad,” said Legarda. She also said space
programs and development are not limited to sending astronauts to space
and engineering space crafts and technologies. (1/3)
