Pluto's Strange Ice Patterns Explained
by New Theory (Source: Nature)
In 2015, NASA’s New Horizons probe sent back some intriguing images of
Pluto. Huge polygonal patterns could be seen on the surface of a
nitrogen-ice ice filled basin known as Sputnik Planitia. This week, a
team put forward a new theory to explain these perplexing patterns. "We
find that sublimation-driven convection readily produces the observed
polygonal structures if we assume a smaller heat flux (~0.3 mW m−2) at
the base of the ice layer than the commonly accepted value of
2–3 mW m−2 (ref. 7). Sustaining this regime with the latter value is
also possible, but would require a stronger viscosity contrast (~3,000)
than the nominal value (~100) considered in this study. (12/15)

How to Prevent Conflicts on the Way to
Mars (Source: The Economist)
The early days of the American space program—days of white-knuckle test
flights and solo orbital missions—called for pilots with qualities such
as supreme self-confidence, unflinching bravado and ice in their veins.
Or, to put it less kindly, “narcissism, arrogance and interpersonal
insensitivity.” That was the assessment of one of NASA’s first staff
psychiatrists, Patricia Santy. Mars astronauts must survive not only
deep space but one another’s company. It took Apollo 11 about three
days to get to the Moon and two days to make it back.
A voyage to Mars will probably be an 18-month round trip in a
spacecraft no larger than a small house, as well as perhaps a year
spent on the planet. Humans are more complicated than spacecraft. But
Dr. Noshir Contractor likens his work to weather-forecasting. Weather
is a complex, non-linear interaction of factors including air
temperature, pressure and wind speed. Yet models can reliably predict
next week’s temperatures and chances of rain. Avoiding conflict can
discourage the creative friction that can generate new or better ideas.
Conflict associated with tasks is different from that associated with
personalities. Conflict over ideas can be helpful. But when conflicts
get personal, things can get ugly.
NASA believes it can now feed prospective crew members’ physical,
intellectual and personality traits into its model and, with 75%
accuracy, predict who will clash with whom during a mission. Equipped
with such information, Dr Contractor’s team is trying to come up with
ways to mitigate problems, including by tweaking the “playbook” given
to crew members. This is the hour-by-hour schedule that lays out
details of tasks, including who will work when with whom. (12/18)

Could This Space Rock Reveal the
Origins of Life? (Source: Daily Beast)
A volunteer meteorite-hunter made an incredible discovery in March this
year while scouring an English field and pleading to the spirit of his
late father for assistance. Derek Robson found one of the oldest,
rarest space rocks in humanity’s possession partially buried in a
horse’s muddy hoofprint. This 4.6-billion-year-old hunk of olivine and
phyllosilicates had apparently fallen to Earth a few weeks earlier
after traveling from some distant point beyond Mars. Now scientists at
Loughborough University, in central England, are gently probing the
fragile, two-inch rock.
The meteorite’s uncontaminated insides could surrender vital clues
about some of the deepest mysteries of our solar system’s early
history. Scientists have begun scrutinizing the meteorite using a
dizzying array of methods and instruments: “vibrational spectroscopy to
identify functional groups, powder x-ray diffraction to identify
different mineralogical phases and elemental analysis to determine the
relation proportions of the chemical elements within the sample.”
They're looking for evidence of amino acids. These acids, which can
survive for billions of years inside meteors, form the proteins that
are found in all living things. The acids are, in other words, the
building blocks of life. To be clear, amino acids have turned up in
other meteorites. But every time scientists find these prebiotics in
some old space rock, they have to ask themselves—was the acid there
before the rock hit Earth? “It is important to be mindful that
terrestrial contamination can be possible.” (12/16)

Science Fiction Revisited: Space
Ramjet Propulsion (Source: Phys.org)
In science fiction stories about contact with extraterrestrial
civilizations, there is a problem: What kind of propulsion system could
make it possible to bridge the enormous distances between the stars? It
cannot be done with ordinary rockets like those used to travel to the
moon or Mars. Many more or less speculative ideas about this have been
put forward—one of them is the "Bussard collector" or "Ramjet
propulsion". It involves capturing protons in interstellar space and
then using them for a nuclear fusion reactor.
Researchers have now analyzed this concept in more detail. The result
is unfortunately disappointing for fans of interstellar travel: it
cannot work the way Robert Bussard, the inventor of this propulsion
system, thought it up in 1960. It was envisioned that particles can be
collected in the proposed magnetic field and guided into a fusion
reactor, allowing acceleration up to relativistic speeds. However, when
the size of the magnetic funnel is calculated, hopes of a visit to our
galactic neighbors quickly fade. To achieve a thrust of 10 million
newtons—equivalent to twice the main propulsion of the Space
Shuttle—the funnel would have to have a diameter of almost 4000

NASA's SLS Rocket Just Got $3.2
Billion More Expensive (Source: Motley Fool)
At an estimated $1.55 billion in cost per launch, and $209 billion
total over its 30-year history, the U.S. Space Shuttle program was
easily NASA's most expensive project since the Apollo Moon Program --
but NASA's next project is going to make it look like a bargain. Two
years ago, an investigation by the U.S. Office of Management and Budget
(OMB) estimated that each time NASA launches its new Space Launch
System (SLS), taxpayers will ante up "over $2 billion." s it turns out,
OMB was being optimistic.
Last week, NASA awarded Northrop Grumman a $3.2 billion contract to
build booster rockets for five SLS rockets that will participate in the
Project Artemis moon program. For each of the Artemis IV, V, VI, VII,
and VIII, Northrop Grumman will build a pair of rocket boosters to help
lift the massive rockets into orbit, then send them on to the moon. The
company will also build a test booster for the Artemis IX "Booster
Obsolescence and Life Extension" (BOLE) program -- so 11 boosters in
all. These boosters are essential to the Artemis program, providing
"more than 75% of the thrust for each SLS launch," as NASA explains,
but they do come at a cost.
Specifically, each rocket booster will cost taxpayers -- and benefit
Northrop Grumman -- more than $290 million. To put that number in
context, when NASA hired SpaceX to launch its Geostationary Operational
Environmental Satellite (GOES) U spacecraft in September, the total
cost of the Falcon Heavy rocket that will do the work -- including the
core stage and two side boosters (all of which are reusable) was just

Launching in August 2022 and arriving at the asteroid belt in 2026,
NASA's Psyche spacecraft will orbit a world we can barely pinpoint from

metal-rich asteroid, also called Psyche, in the main belt between Mars

space-based telescopes, the asteroid appears as a fuzzy blur. What
scientists do know, from radar data, is that it's shaped somewhat like
a potato and that it spins on its side.
By analyzing light reflected off the asteroid, scientists hypothesize
that asteroid Psyche is unusually rich in metal. One possible
explanation is that it formed early in our solar system, either as a
core of a planetesimal—a piece of a planet—or as primordial material
that never melted. This mission aims to find out, and in the process of
doing so, they expect to help answer fundamental questions about the

Artemis I Integrated Testing Update
(Source: NASA)
NASA’s Space Launch System (SLS) rocket and Orion spacecraft are
undergoing integrated testing at the Cape Canaveral Spaceport to ensure
they are “go” for launch of the Artemis I mission early next year.
After stacking the Orion atop the SLS rocket, the engineers completed
several tests to ensure the rocket and spacecraft are ready ahead of
the Artemis I wet dress rehearsal. These tests included ensuring Orion,
the core stage, and boosters can communicate with the ground systems
and verification testing to make sure all the pieces of the rocket and
spacecraft can power up and connect to the consoles in the Launch
control Center.
During a recent core stage power test, engineers identified an issue
with one of the RS-25 engine flight controllers. The flight controller
works as the “brain” for each RS-25 engine, communicating with the SLS
rocket to provide precision control of the engine as well as internal
health diagnostics. Each controller is equipped with two channels so
that there is a back-up, should an issue arise with one of the channels
during launch or ascent. In the recent testing, channel B of the
controller on engine four failed to power up consistently. The
controller had powered up and communicated successfully with the
rocket’s computers during preliminary integrated testing, in addition
to performing a full duration hot fire during Green Run testing with
all four RS-25 engines earlier this year at NASA’s Stennis Space
Center.
NASA and lead contractor for the RS-25 engines, Aerojet Rocketdyne,
also test all RS-25 engines and flight controllers for Artemis missions
at Stennis prior to integration with the rocket. After performing a
series of inspections and troubleshooting, engineers determined the
best course of action is to replace the engine controller, returning
the rocket to full functionality and redundancy while continuing to
investigate and identify a root cause. (12/17)

minimal inspections.
The vehicle does feature an engine that looks “very different from
conventional engines,” Lapsa said, but didn’t reveal design details.
That design will enable it to operate both at low altitudes and in
vacuum. “It’ll be by far the highest performing rocket engine for any

Space Force Marks Second Anniversary
(Source: Space News)
The U.S. Space Force marks its second anniversary. Over the past two
years its ranks have grown to more than 6,500 uniformed members known
as guardians, and about an equal number of civilian employees. Lt. Gen.
Nina Armagno, director of the Space Force staff, said last week that
the service got off to a rough start as the public did not understand
why a military branch for space was needed. She suggested that a
drumbeat of news reports about China's technological advances in space
and hypersonic missiles, and Russia's ASAT test last month, provided
clear illustrations of the role that space plays in national security.

China's New Heavy-Lift Human-Rated
Rocket Testing Planned in 2026 (Source: Space News)
China could conduct the first test flight of a heavy-lift rocket
intended to support human lunar exploration as soon as 2026. Long
Lehao, a senior space industry figure and Long March launch vehicle
designer, told state media that schedule earlier this month. The
envisioned crew-rated rocket would be capable of sending 27 metric tons
into lunar transfer orbit and uses technologies developed for the Long
March 5. The new rocket may offer a faster approach to human lunar
missions than the larger Long March 9 slated to make its first launch
late this decade. (12/20)
Boeing Starliner Test Flight Could
Launch in May 2022 (Source: Space News)
A CST-100 Starliner uncrewed test flight delayed from August could take
place next May. NASA and Boeing announced last week that they will
switch service modules for that OFT-2 test flight, with OFT-2 now using
the service module originally constructed for the Starliner's crewed
test flight, with a May launch of OFT-2 now under consideration. That
will allow engineers to continue to investigate the cause of stuck
valves in the original OFT-2 service module that postponed an August
launch of the mission. (12/20)
Axiom to Send Second Private Astronaut
Mission to ISS (Source: Space News)
NASA selected Axiom Space for a second in a series of private astronaut
missions to the ISS. The Ax-2 mission will launch between the fall of
2022 and late spring of 2023, spending up to two weeks on the station.
The Crew Dragon spacecraft for Ax-2 will be commanded by former NASA
astronaut Peggy Whitson with an Axiom customer, John Shoffner, serving
as pilot. Axiom is gearing up for the Ax-1 mission to the station
scheduled for launch no earlier than Feb. 21. (12/20)
Malaysia Developing Space Engagement
Plan (Source: Space News)
Malaysia is developing a national space blueprint to drive the growth
of its space sector. The "Malaysia Space Exploration 2030" blueprint,
presented by a government minister at a parliamentary hearing last
week, focuses on the manufacturing of remote-sensing satellites,
satellite components and data-driven downstream services. The plan also
includes bolstering international cooperation by signing MOUs with
"agencies of excellence in developed countries in the field of space
technology." (12/20)
Texas Mayor Reassures Residents That
Noise From SpaceX Engine Testing Will Abate Soon (Source: KXXV)
Residents near a SpaceX Texas test site will have to put up with
additional noise from engine testing for a few more weeks. In a letter
last week, the mayor of McGregor, Texas, said the increased noise from
the SpaceX engine test site there was because of a switch to tests of
Raptor 2 engines on a horizontal test stand. SpaceX is working to
complete a second vertical test stand, which will reduce the noise
residents hear, but the mayor said that new test stand would take two
to three more weeks to complete. (12/20)

Florida Tech Astrophysicist Ready for
Webb Telescope’s Answers (Source: Florida Tech)
A fledgling astronomer since early childhood and now an accomplished
astrophysicist at one of the country’s leading research institutions,
Florida Tech’s Eric Perlman is excited about Dec. 24. That’s when the
$10 billion James Webb Space Telescope is scheduled to launch from
French Guiana. About six months later, after the device’s deployment
and checkout from its position more than one million miles from Earth,
the quest for answers to some of the biggest astrophysical mysteries
should be underway.
Over his nearly 30-year career, Perlman has been awarded time on major
telescopes including the Chandra X-ray Observatory and the Hubble Space
Telescope. The latter had been the most powerful tool for space-based
observations. However, with its 21-foot diameter mirror (the Hubble’s
was 8 feet), Webb can make an observation similar to Hubble’s famous
Ultra Deep Field observation, which took 16 days, in a speedy seven
hours. More importantly, it can peer far deeper into space – more than
13 billion years ago. (12/15)

AFRL Jumpstarts Early Research on
Cislunar Monitoring, Satellite Servicing (Source: Breaking
Defense)
The Air Force Research Laboratory has chosen the first two winning
teams in its new Space University Research Initiative (SURI) program,
with research projects designed to build on-orbit servicing
capabilities and improve space monitoring, including in cislunar space
beyond Earth’s orbit. Maj. Gen. Heather Pringle, AFRL director, told
reporters today that the SURI program “started out as a pilot” and is
aimed at transitioning “high-risk, high-reward ideas in science” to
“applied technology and advanced technology development. SURI is being
managed by AFRL’s Air Force Office of Scientific Research (AFOSR), and
is aimed at combining so-called 6.1 basic research with early 6.2
applied research.
In March 2021, the lab issued a notice of the first funding opportunity
under SURI, with “awards of up to $1,000,000 per year per award
spanning three to five years in the areas of Space Logistics and
Mobility and Space Domain Awareness (SDA).” The winning proposal in the
logistics and mobility arena is called “Breaking the ‘Launch Once, Use
Once’ Paradigm.” Its goal is to develop “fundamental and applied
research” for On-orbit Servicing, Assembly, and Manufacturing that can
be transitioned to AFRL’s Space Vehicles Directorate and Northrop
Grumman.
In the Space Domain Awareness (SDA) category, the winning proposal is
titled “Space Object Understanding and Reconnaissance of Complex Events
(SOURCE).” SOURCE will push “techniques for analyzing sensor data” as
it researches “how to build more efficient algorithms for sampling
modeling and predicting dynamics in orbit.” (12/20)
