How Do We Prevent War in Space?
(Source: Scientific American)
On January 30, 2020, an amateur satellite watcher tweeted, “Something
to potentially watch.” Cosmos 2542, a Russian inspection satellite, was
“loitering around” USA 245, an American spy satellite, and, he wrote,
“as I'm typing this, that offset distance shifts between 150 and 300
kilometers.” USA 245 then adjusted its orbit to get away from Cosmos
2542, which in turn tweaked its own orbit to get closer again. “This is
all circumstantial evidence,” the watcher wrote, but “a hell of a lot
of circumstances make it look like a known Russian inspection satellite
is currently inspecting a known U.S. spy satellite.”
So here we are, with the possibility of an escalating space war that
would bring certain and incalculable civilian consequences. Yet
attempts at diplomacy have been lackluster, and the military's response
sounds as aggressive as it does protective. “I don't know if space war
is imminent,” says John Lauder, a 30-year veteran of the intelligence
community's arms-control monitoring efforts, “but there are trends that
make space more dangerous. It's not sitting on top of us, but it's
moving in our direction at a rapid speed.”
Most efforts at defense tend to focus on deterrence. “The natural place
for the military to go is deterrence by punishment,” Grego says. “You
use ASAT on me; I'll use it on you.” The first problem with punishment,
though, is unpredictable escalation. The second is the flip side of
U.S. vulnerability—that Russia and China do not need their military
satellites as much as the U.S. does. Alternatively the U.S. could deter
attacks by denying their benefits. In other words, a redundant,
resilient system that could take losses without losing effectiveness
would not be as attractive a target. (11/1)
NASA Seeks New Partners to Help Put
All Eyes on Artemis Moon Missions (Source: NASA)
NASA is seeking new partners to help the agency tell the story of human
exploration at the Moon with the Artemis program in ways that engage,
excite, and inspire a worldwide audience. Through the end of this
decade, NASA will explore more of the lunar surface than ever before
and will establish a sustainable human presence with Artemis in
preparation for future human missions to Mars.
The agency has released an Announcement for Proposals calling for
submissions of potential partnerships to visually bring the public
along for the ride in new ways, starting as early as a trip around the
Moon with astronauts on the Artemis II mission, targeted for 2023.
Proposals are Dec. 11, 2020. “We’re looking for partners to use
advanced technologies, imagery applications and approaches that will go
beyond our standard coverage on NASA TV,” said NASA Administrator Jim
Bridenstine. (11/5)
The CEO of a $1.2 Billion Space
Company Can’t Use its Technology (Source: Quartz)
Mikhail Kokorich, the CEO of Momentus Space, is legally barred from
accessing his company’s technology because he is a Russian national and
has been unable to obtain US government permission to work with
export-controlled space vehicles. This may have implications for the
company’s planned $1.2 billion IPO.
While executive leadership doesn’t always require technical chops, it’s
hard to imagine SpaceX succeeding if it were against the law for Elon
Musk to look at the rocket designs. This unusual scenario could bolster
SPAC critics who say the method of going public lends itself to
companies looking to avoid the scrutiny of a typical public offering in
a frothy market driven by retail investors.
In 2018, the US government forced Kokorich to give up his ownership of
another space company, Astro Digital, when it failed to pass a foreign
influence review, according to three people familiar with the
transaction. Investigators asked about Kokorich’s access to satellite
technology that, under US law, can only be used by citizens or
permanent residents. (11/5)
Astronomers Discover … Earth??

Scientists have discovered a terrible, inhospitable hell planet
floating through space. And before you say, “Uh, I know, lady. I live
here!” allow me to clarify: They’ve found a second terrible hell
planet, besides ours. In a new paper, astronomers from York University,
McGill University, and the Indian Institute of Science Education and
Research presented their models for the atmosphere and weather of
K2-141b, a “lava planet” located roughly 200 light-years away. The
planet rains rocks, has an enormous lava ocean over 60 miles deep, and
winds whip across its surface at speeds more than four times the speed
of sound. (11/4)

‘Moonbase 8’: TV’s Latest Space Oddity
(Source: Rolling Stone)
I’m not sure I’ve ever seen anything like the last 12 months or so,
when we’ve gotten six different shows about space travel: Apple TV+’s
alternate-history drama For All Mankind, HBO’s futuristic farce Avenue
5, Netflix’s workplace sitcom Space Force, Netflix’s earnest (and
short-lived) mission to Mars drama Away, Disney+’s dull remake of The
Right Stuff, and now Showtime’s quirky comedy Moonbase 8, starring John
C. Reilly, Fred Armisen, and Tim Heidecker as NASA afterthoughts
simulating lunar life in the Arizona desert.
How, exactly, did we arrive at Peak Astronaut TV? Especially since all
of these series were developed and produced well before this perilous
moment in history, when simply leaving the house can feel as risky as
sitting atop a rocket bound for orbit. There’s something scary in the
air right now, but how did the people behind this work sense it a year
or two ago? More importantly, why are most of these shows so
disappointing?
Moonbase 8 at least feels timely, if not especially funny, since its
subject matter is about the psychological challenge of prolonged
isolation from all but a handful of people. When the season begins, Cap
(Reilly), Skip (Armisen), and Rook (Heidecker) have been on assignment
for more than 200 days. They are bored, frustrated, and only vaguely
competent. (And most of that skill is via NASA legacy Skip, where Cap
and Rook come across like each won the job via a scratch-off lottery.)

In ‘Proxima,’ Eva Green Preps for
Space Travel in a Sexist World (Source: Datebook)
“Proxima” is a film about a female astronaut that feels more authentic
and emotionally attuned than similar recent efforts, such as Netflix’s
already-canceled “Away” television series and the film, supposedly
“inspired by true events,” “Lucy in the Sky.” Perhaps that’s because
“Proxima” remains a down-to-earth affair, most of the way, toward
liftoff. The film centers around the training and issues facing Sarah
Loreau — played by Eva Green in her finest and most demanding
performance to date — after she’s chosen for an International Space

Sen. Cory Gardner (R-CO) conceded his defeat fairly early yesterday
evening, losing to former Governor John Hickenlooper. Gardner is a
member of the Senate Commerce, Science, and Transportation Committee
and of its Aviation and Space subcommittee. Gardner is one of the
original co-sponsors of the PROSWIFT space weather bill, along with
Sen. Gary Peters (D-MI), that was just enacted after five years of
effort. Two amendments Gardner added to the Senate version of the
NASA authorization bill (S. 2800) reportedly are holding up its
consideration by the Senate. They would place extra requirements on
NASA before it signs contracts with companies that might have

NASA Begins Wind Tunnel Testing For
Electric X-Plane Props (Source: AvWeb)
The propeller designs for NASA’s all-electric X-57 Maxwell have now
undergone two weeks of wind tunnel testing, the agency said on Monday.
The propeller assemblies, supplied by California-based contractor
Empirical Systems Aerospace (ESAero), logged 14 hours of powered
operation during testing with wind speeds up to around 90 knots. The
tests took place at the low-speed aeroacoustic wind tunnel at NASA’s
Langley Research Center in Hampton, Virginia.
As part of the fourth and final modification (Mod IV) of the X-57’s
phased development process, twelve electric motors and propellers will
be installed along the leading edge of the aircraft’s wing. According
to NASA, those motors will only be used for takeoff and landing while
the Maxwell’s two larger electric cruise motors—located on the
wingtips—will be utilized throughout operations. The propeller blades
associated with the smaller engines will fold inward when not in use.

Nuclear Tech in Space: What’s on the
Horizon? (Source: ANS)
NASA aims to develop nuclear technologies for two space applications:
propulsion and surface power. Both can make planned NASA missions to
the moon more agile and more ambitious, and both are being developed
with future crewed missions to Mars in mind. Like advanced reactors
here on Earth, space nuclear technologies have an accelerated timeline
for deployment in this decade.
Space nuclear propulsion and extraterrestrial surface power are getting
funding and attention. New industry solicitations are expected this
month, and a range of proposed reactor technologies could meet NASA’s
specifications for nuclear thermal propulsion (NTP). Nuclear electric
propulsion could increase the feasibility of crewed missions to Mars
with a shorter transit time, a broader launch window and more
flexibility to abort missions, reduced astronaut exposure to space
radiation and other hazards, expanded payload mass capabilities, and
reduced cost. (11/4)
Texas Satellite Company Defends Itself
Against NASA Criticisms (Source: Ars Technica)
The founder of a Texas-based company that wants to put more than 200
very large satellites into low-Earth orbit has pushed back on concerns
from NASA that these spacecraft pose an orbital debris threat. “We’re
not a bunch of cowboys launching satellites,” said Abel Avellan,
founder of AST & Science. "This is a serious, well-funded project."
The company, which has 160 employees and has moved into XCOR's old
facility at Midland's airport, has asked the FCC for access to the US
market to sell Internet connectivity to mobile phones from space.
NASA took the rare step of objecting to the AST mega-constellation
proposal to put as many as 243 satellites in an orbit at 720km,
commenting last Friday that it could lead to a "catastrophic collision"
with its A-Train satellites in a nearby orbit. Avellan said the
"SpaceMobile" satellites do indeed have a very large cross-sectional
area perpendicular to the ground, as this is the only way to deliver
direct satellite-to-broadband signals. "There is no magic," he said.
"If you want something to connect directly to a handset, it’s not going
to be a CubeSat." (11/5)

Radio Burst Traced to Star

A mysterious radio burst has been traced to a star in our galaxy.
Astronomers first detected fast radio bursts, or FRBs, in 2007, but had
not identified a specific source for any of them, or even determined if
they were from within our galaxy or outside of it. Research published
Wednesday identified the source of one FRB, a type of neutron star
called a magnetar and designated SGR 1935+2154. This magnetar, located
30,000 light-years away, has intense magnetic fields, and astronomers
believe that flares of activity by such stars could produce the FRBs
detected by radio astronomers. (11/5)

Impact Craters on Earth
(Source: Space Daily)
The formation of craters by asteroid and comet impact has always been a
fundamental process in the solar system, explains Kenkmann. As the
planets developed along with their moons, these impacts played an
important part in accreting planetary mass, shaping the surfaces of
planetary bodies, and later also influencing their development. And
larger meteorite impacts eventually affected the development of life on
Earth.
Today, mapping of what can still be seen of the impact structures on
the Earth's surface can be done by satellites in low Earth orbit. From
2010 to 2016, the DLR successfully measured the Earth's surface with
the radar satellites of the TanDEM-X mission. The acquired data
allowed, for the first time, to derive a worldwide terrain model with a
height accuracy of up to one meter. From this global digital elevation
model the authors have been able to produce this complete topographic
atlas of 600 pages with information about all terrestrial impact
craters known to date. Click here.

Microbial Space Travel on a Molecular
Scale (Source: Space Daily)
Since the dawn of space exploration, humankind has been fascinated by
survival of terrestrial life in outer space. Outer space is a hostile
environment for any form of life, but some extraordinarily resistant
microorganisms can survive. Such extremophiles may migrate between
planets and distribute life across the Universe, underlying the
panspermia hypothesis or interplanetary transfer of life.
The extremophilic bacterium Deinococcus radiodurans withstands the
drastic influence of outer space: galactic cosmic and solar UV
radiation, extreme vacuum, temperature fluctuations, desiccation,
freezing, and microgravity. A recent study examined the influence of
outer space on this unique microbe on a molecular level. After 1 year
of exposure to low Earth orbit (LEO) outside the International Space
Station during the Tanpopo space Mission, researches found that D.
radiodurans escaped morphological damage and produced numerous outer
membrane vesicles. (11/5)
