This Robot’s Journey to
an Icy Alien Moon Starts Beneath Antarctica (Source: New
York Times)
Near a nice, big hole in the ice and beneath the stone gray, midday
Antarctic summer skies, six Adélie penguins stared at six men toiling
with tools. The chasm in the ice might have been an inviting entry to
the krill-rich waters below. None of the members of the tuxedoed recon
party dove into the hole, a square about six feet across. The risk of
leopard seals was just too great. But had they leapt in, the penguins
would have discovered not a seal, but a robot.
In November, scientists and engineers from NASA’s Jet Propulsion
Laboratory successfully field tested Bruie — the “Buoyant Rover for
Under-Ice Exploration” — beneath the ice of eastern Antarctica. The
remotely operated rover was built to crawl along the underside of sea
ice and ice shelves. These tests on Earth have a long-term goal of one
day seeking evidence of life beneath the thick frozen shell covering
Jupiter’s ocean moon of Europa. Beneath that ice is three times more
liquid water than can be found in all the oceans on Earth. (1/5)
LIGO Detects its Second
Neutron Star Collision, But Gains Few Clues (Source:
Science News)
For the second time, a collision between two neutron stars in another
galaxy has rattled a gravitational-wave detector on Earth. But this duo
is being much more coy than the first. In 2017, astronomers announced
with much fanfare that they had detected ripples in spacetime, from the
merging of two neutron stars, the ultradense remains of massive stars.
Observatories around the world and in space witnessed a simultaneous
flash of radiant energy, light from all across the electromagnetic
spectrum.
Now, gravitational waves from a second neutron star smashup have been
detected. But unlike the first detection, researchers were not able to
pinpoint the collision’s location on the sky and did not see an
accompanying burst of light. Katerina Chatziioannou, an astrophysicist
at the Flatiron Institute in New York City, presented the results
January 5 at meeting of the American Astronomical Society. (1/5)
No Dark Energy? No
Chance, Cosmologists Contend (Source: Quanta)
Dark energy, mysterious as it sounds, has become part of the furniture
in cosmology. The evidence that this repulsive energy infuses space has
stacked up since 1998. That was the year astronomers first discovered
that the expansion of the universe has been speeding up over time, with
dark energy acting as the accelerator. As space expands, new space
arises, and with it more of this repulsive energy, causing space to
expand even faster.
Two decades later, multiple independent measurements agree that dark
energy comprises about 70% of the universe’s contents. It is so baked
into our current understanding of the cosmos that it came as a surprise
when a recent paper published in the journal Astronomy &
Astrophysics questioned whether it’s there at all.
The four authors, including the Oxford physicist Subir Sarkar,
performed their own analysis of data from hundreds of supernovas — the
stellar explosions that provided the first evidence for cosmic
acceleration, a discovery that earned three astronomers the 2011 Nobel
Prize in Physics. When Sarkar and his colleagues looked at supernovas,
they didn’t see a universe that’s accelerating uniformly in all
directions due to dark energy. Rather, they say supernovas look the way
they do because our region of the cosmos is accelerating in a
particular direction — roughly toward the constellation Centaurus in
the southern sky. (1/6)
China's Heaviest
Satellite Positioned in Geosynchronous Orbit (Source:

China's heaviest and most advanced satellite, Shijian-20, reached its
fixed position in geosynchronous orbit Sunday, marking the first
successful flight of DFH-5 satellite platform, according to the China
Aerospace Science and Technology Corporation. The Shijian-20 satellite
is the first verification satellite for DFH-5 satellite platform,
China's new generation of large geosynchronous orbit satellite platform.
At present, the satellite has completed the orbit transfer and verified
the key technologies of the DFH-5 satellite platform, according to Li
Feng, chief designer of the satellite. The Shijian-20 satellite was
launched into space by the third Long March-5 rocket, China's largest
carrier rocket on Dec. 27, 2019. It has carried out orbit experiments
for a series of key technologies. (1/5)
New Mexico Higher Ed Can
Help Spaceport Careers Take Off (Source: Albuquerque
Journal)
The story of the education-to-career opportunity afforded by continued
investment in Spaceport America cannot be overstated. At the Department
of Higher Education, we are very in tune with the changing needs of the
workforce and are constantly striving with higher education
institutions, regional partners and employers to meet those needs.
Recently, when Virgin Atlantic announced its expanded home operations
at Spaceport America, Lexy Snell shared her story of just how real and
important the work of connecting the dots throughout our institutions
is. Lexy’s story is truly that of the American dream and a big way in
which New Mexicans have the chance to experience a similar story of
success.
Lexy now works for Virgin Galactic and was part of the team that put
its Unity rocket into space this year. She did not start out knowing
that was her path, moving frequently as a child, as so many New
Mexicans experience. She eventually found her way to Central New Mexico
Community College’s aviation tech program, where she became the second
woman to graduate from the program. Now, she is part of a team making
history at Spaceport America. Lexy’s story is one we can repeatedly see
in New Mexico as more and more companies make their home at Spaceport
America.
And we as a state must continue to capitalize on this opportunity.
Working with New Mexico State University and the University of New
Mexico, we recently created a new Ph.D. program in geography, as we
recognize the changing climate and the need to be able to better
address firefighting with deeper and broader GIS and GPS knowledge.
Imagine a collaboration between students in this program and companies
housed at the Spaceport, looking at innovative delivery systems for
fire retardant to help us more quickly and safely address the impacts
of wildfires. (1/5)

Space Force Transition
Still a Work In Process (Source: Space News)
“I’m excited for the 45th Space Wing to be a part of the U.S. Space
Force,” wing commander Brig. Gen. Doug Schiess said in a statement Jan.
3. The 45th Space Wing will continue to do what it has been doing and
the transition to the Space Force will not change that, Schiess said.
The details of how the U.S. Space Force will be structured and staffed
will take at least 18 months to sort out. For now the Space Force will
be composed of uniformed and civilian personnel who worked under the
Air Force Space Command. AFSPC personnel have been assigned to the
Space Force but still remain airmen within the U.S. Air Force. Over the
next year, the Air Force will figure out a process to allow service
members to leave the Air Force and officially transfer into the Space
Force.
There are about 16,000 Air Force personnel that support the five space
wings and are now part of the new branch. Besides the 45th Space Wing
in Florida is the 30th Space Wing at Vandenberg Air Force Base,
California; the 21st Space Wing at Peterson Air Force, Colorado; the
50th Space Wing at Schriever Air Force Base, Colorado; and the 460th
Space Wing at Buckley Air Force Base, Colorado. (1/6)

The Year of the Satellite
Megaconstellation (Source: The Wire)
The talk of 2019 has been a new kind of space race. Not the battle for
supremacy among the major private companies (like those of billionaires
Elon Musk, Jeff Bezos, and, to a lesser extent, Richard Branson) and
other space-focused startups, but one around something much smaller,
with potentially bigger implications: satellite constellations.
Established companies and startups alike are zeroing in on launching
large networks of small satellites (generally considered anything under
500 kilograms—in comparison, the Hubble Space Telescope is more than
11,000 kilograms). These are poetically called constellations, and they
join most other satellites and the International Space Station in low
Earth orbit. These small satellites are cheaper, easier to manufacture,
and less expensive to send to space than their larger counterparts. And
by working in concert, they can collectively cover a much bigger
portion of the Earth than standard satellites, making them perfect for
goals such as blanketing the globe in affordable high-speed internet.
Providing low-cost, fast internet to hard-to-reach areas is a worthy
goal. It would give people in rural areas and areas with poor
infrastructure an affordable way to connect to the internet and
participate in the digital economy—in the US, roughly 25 million people
still don’t have access to broadband internet. (1/6)

Space: The Final
Frontier...Of Telemedicine? (Source: Forbes)
No, it wasn’t a trip to the USS Enterprise, either in the current Star
Trek movie series or back to the famed TV series in the 1960’s and
‘70’s. If only. But this adventure in space medicine was a close
second. Two months into a six month stint on the International Space
Station (ISS), one of the astronauts developed a blood clot in one of
the large veins in the neck. This was found as part of a research study
they were engaged in, whereby ultrasounds of their neck veins were
being performed during the trip—not to look for blood clots, but to
look at other issues related to space travel and bodily fluid function.
A large clot was found in the large vein that drains the blood in the
head and neck (internal jugular vein), even though the astronaut (who
remains anonymous) was not having any symptoms.
NASA contacted Dr. Stephan Moll, a Professor of Medicine and
Hematologist-Oncologist at the University of North Carolina, who has
specialized expertise in thrombosis (blood clots) and use of various
anticoagulants, or blood thinners. While Dr. Moll, who is also the
founder of the Clot Connect outreach project, did not get the
opportunity to make the trip to the space station, he did provide the
longest distance telemedicine consultation to date, helping make the
decision on how to treat the blood clot.
The type of blood clot, known as a DVT, or deep vein thrombosis, is
typically seen in the setting of long airplane flights (over four
hours), after long periods of being sedentary, including car trips,
being bedridden, or even during or right after undergoing a long
surgery. For many of these instances, there are measures to take to
prevent these. For travel, it is recommended to move your legs often
and exercise calf muscles either while seated in a car or plane, or by
taking car trip breaks or getting up to walk when it’s safe on a
flight. Click here.

'Pin'-nacle Achievement:
The Story Behind NASA's Astronaut Pin (Source:
CollectSpace)
As test pilots, the Mercury astronauts earned their wings from their
respective branches of the U.S. military. On Dec. 6, 1961, Alan Shepard
and Virgil "Gus" Grissom, the first Americans to fly into space, were
presented with the U.S. Navy's and U.S. Air Force's first astronaut
wings, respectively, at a joint ceremony held at the Pentagon.
The wings resembled the two branches' aviator badges, but were modified
with a device at their center featuring a five-pointed star with three
trailing rays passing through a halo. For their civilian wear (i.e.
business suits), the Mercury astronauts wore a pin that merged the
symbol for the planet Mercury with the Arabic numeral "7." As NASA's
human spaceflight program expanded, though, a new pin was needed. "The
design shows a trio of trajectories merging in infinite space, capped
by a bright shining star and encircled by an elliptical wreath denoting
orbital flight."
The new astronaut pin, which borrowed its design from the military
badge, was chosen by the astronauts themselves at a get together
organized by Mercury (and later Gemini and Apollo) pilot Wally Schirra.
A silver version of the lapel pin, like the type being presented to the
Group 22 candidates on Friday, denoted the competition of basic
training. Astronauts earn their gold pin by flying into space. (1/6)
UAE Leaders Sign Final
Piece of Hope Probe Destined for Mars (Source: The

The final piece of a UAE-built probe destined for Mars was signed by
two of the country’s leaders on Sunday. At the Presidential Palace in
Abu Dhabi, Sheikh Mohammed bin Rashid, Vice President and Ruler of
Dubai, and Sheikh Mohamed bin Zayed, Crown Prince of Abu Dhabi and
Deputy Supreme Commander of the Armed Forces, wrote an inspirational
message for the rest of the Arab world on a piece of the outer casing
of the Hope probe.
“The power of hope shortens the distance between the Earth and sky,”
the two wrote in Arabic. The metal piece will be attached to the probe
before it is launched into space this year to study the atmosphere on
Mars. “Today me and my brother Mohamed bin Zayed signed the last piece
of the outer structure of the Hope probe, the first Arab-Islamic probe
to reach Mars,” Sheikh Mohammed said on Twitter.
He said the phrase, which will be engraved, “sends a message to all
Arab youth that we are able to succeed and compete and not to lose the
power of hope that can move mountains”. In a tweet, Sheikh Mohamed
confirmed the probe would launch in July. The launch window was chosen
because it is the time that Earth and Mars will be at their closest
point. This only happens once every two years. “Buoyed by the
determination of our youth, we are proceeding with our space programme
to serve science and humanity,” Sheikh Mohamed said. (1/6)
