Company That Aims to Race SpaceX to
Mars Plays with Fire (Source: Ars Technica)
There's a small rocket company based in eastern California named Pythom
Space. And like a lot of space startups, it has big dreams. In this
case, co-founders Tina and Tom Sjögren have the goal of flying to Mars
in 2024—and if not then, by 2026. This seems naïve, of course. Even
SpaceX, which from the beginning was well-funded and able to hire
excellent early employees, is still years away from sending humans to
Mars after its founding in 2002.
So Pythom Space is pressing ahead with its ambitious goal of building a
rocket, a spacecraft, and a Mars lander. The company's first step is to
build a small rocket, Eiger, with the capability to lift 150 kg to low
Earth orbit. According to the company's website, 90 percent of a
rocket's cost in the traditional space industry is related to
personnel. Accordingly, the website says, "Pythom runs small teams and
tight facilities, building in the spirit of early explorers such as
Lewis & Clark and Roald Amundsen."
One area in which Pythom appears to be saving personnel costs is its
safety and mission assurance department. On March 19, the company
conducted a hold-down test of the first stage of its Eiger rocket with
a single engine. (The complete first stage will have nine small
engines.) The video shows a number of instances in which Pythom
employees appear to be handling the Eiger rocket and its hypergolic
propellants (furfuryl alcohol and nitric acid) with less than
industry-standard care. (4/11)
Houston Astros Launch New 'Space City'
Uniforms with Nods to NASA (Source: CollectSpace)
The Houston Astros are celebrating their home city's connection to
space exploration with a new uniform inspired in part by NASA's
astronaut wear and materials. The Major League Baseball team debuted
their new Nike City Connect uniforms ahead of the players wearing them
for the first time when they face the Los Angeles Angels on April 20.
The new uniform's jersey features "Space City" stenciled boldly across
the chest in a font inspired by NASA's logotype affectionally known as
the "worm." Houston adopted "Space City" as its official nickname in
1967 after NASA established its Manned Spacecraft Center (today,
Johnson Space Center) in southeast Houston. (4/10)
South Korea Needs a National Space
Policy (Source: JoongAng Daily)
“Does Korea have a space policy?” a U.S. official asked me when I
visited the State Department a few years ago. He knew of the government
research projects on space exploration in Korea, but was unable to
identify a specific space-related public policy. The official had been
handling space-related affairs for decades, but his counterpart in
Seoul was replaced every one or two years.
Space development can demonstrate full national capabilities as it is
connected and coordinated with science and technology and industrial,
military, political and diplomatic capabilities. Over 70 governments
have state agencies devoted to space development. Korea does not have
one. It merely has a space technology division at the Ministry of
Science and ICT. This is why a U.S. State Department official can ask
if Korea has a space policy.
The government must ready a space vision timed with the 100th
anniversary of liberation in 2045. The new president must establish a
government office on space programs to guide the country’s next
century. Korea is No. 10 in terms of GDP. Russia, a space powerhouse,
is 11th. (4/10)

The leaders of the House Science Committee have asked the White House
to withdraw controversial proposed spaceflight regulations by NTSB. In
a letter to President Biden last week, the chair and ranking member of
the committee said the proposed regulations by NTSB that would allow it
to investigate any commercial launch or reentry accident were “plainly
unlawful” since federal law delegates that responsibility to the FAA
through the Secretary of Transportation. Much of the industry
criticized the regulations as disruptive and duplicative during a
public comment period earlier this year. (4/11)
ULA Buys 116 RL10C-X Upper Stage
Engines from Aerojet Rocketdyne (Source: Aerojet Rocketdyne)
ULA has awarded the largest RL10 contract ever to Aerojet Rocketdyne to
deliver 116 RL10C-X engines for its Vulcan Centaur rocket. The new
engines will support ULA as it works to fulfill its commitments under a
contract they recently received from Amazon to support the launch of
its Kuiper satellite constellation.
The RL10C-X uses a 3D-printed main injector and main combustion
chamber, as well as a 94-inch monolithic lightweight composite
(carbon-carbon) nozzle. The specific impulse, or Isp, of the RL10C-X is
461 seconds, which puts it near the very top of the RL10 engine family
in terms of performance. Similar to gas mileage in a car, specific
impulse measures the amount of thrust generated by a rocket engine per
unit of propellant consumed per second. (4/11)
Space Force is Releasing Decades of
Tracking Data on a Thousand Bright Meteor Fireballs (Source:
Universe Today)
When a meteoroid enters the Earth’s atmosphere at a very high speed it
heats up. This heating up produces a streak of light and is termed a
meteor. When a meteor is bright enough, about the brightness of Venus
or brighter, it becomes a fireball. Sometimes these fireballs explode
in the atmosphere, becoming bolides. These bolides are bright enough to
be seen even during the day.
Studying bolides as they pass through the atmosphere can help model
larger asteroids, something of interest to the Planetary Defense
Coordination Office (PDCO) which is run by NASA. These asteroids can be
deadly if they are large enough, and learning how to predict their
behavior is essential to protecting our planet from a devastating
impact with long-term implications for the survival of many species on
Earth.
Information on these bolides is collected by U.S. government sensors
run by the U.S Space Force and is shared with the NASA Jet Propulsion
Laboratory’s Center for Near Earth Object Studies (CNEOS). NASA has
been tasked with detecting and categorizing near-Earth Objects (NEOs)
that may be detrimental to our planet in an effort to find ways to
divert or otherwise remove the threat they pose. The information they
have for nearly one thousand bolide events goes back to 1988. (4/10)

Is the Origin of Dark Matter Gravity
Itself? (Source: Space.com)
A new model of the very early universe proposes that the graviton, the
quantum mechanical force carrier of gravity, flooded the cosmos with
dark matter before normal matter even had a chance to get started. The
proposal could be a way to connect two of the biggest outstanding
puzzles in modern cosmology: the nature of dark matter and the history
of cosmic inflation.
When inflation ended, it triggered the creation of all known particles.
So, presumably, that same event also manufactured dark matter.
Cosmologists aren't sure what dark matter is made of, but an abundance
of evidence suggests that it's some new, unknown kind of particle.
Whatever this particle is, it accounts for over 80% of all the matter
in the universe.
Now, a pair of physicists proposed a new mechanism to generate lots of
dark matter in the early universe, even if the inflaton didn't like to
produce dark matter. And that new mechanism relies purely on gravity.
This mechanism, which the physicists outlined in a paper in the
preprint database arXiv, assumes that the inflaton and the dark matter
don't talk to each other, so the dark matter particle isn't produced in
the normal way at the end of inflation. (4/10)

Ten New Gravitational Waves Found in
LIGO-Virgo's O3a Data (Source: Space Daily)
In the last seven years, scientists at the LIGO-Virgo Collaboration
(LVC) have detected 90 gravitational waves signals. Gravitational waves
are perturbations in the fabric of spacetime that race outwards from
cataclysmic events like the merger of binary black holes (BBH). In
observations from the first half of the most recent experimental run,
which continued for six months in 2019, the collaboration reported
signals from 44 BBH events.
But outliers were hiding in the data. Expanding the search, an
international group of astrophysicists re-examined the data and found
10 additional black hole mergers, all outside the detection threshold
of the LVC's original analysis. The new mergers hint at exotic
astrophysical scenarios that, for now, are only possible to study using
gravitational wave astronomy.
Notably, the observations included phenomena from both high- and
low-mass black holes, filling in predicted gaps in the black hole mass
spectrum where few sources have been detected. Most nuclear physics
models suggest that stars can't collapse to black holes with masses
between about 50 and 150 times the mass of the sun. (4/8)
Differences Between the Moon's Near
and Far Sides Linked to Colossal Ancient Impact (Source: Space
Daily)
The face that the Moon shows to Earth looks far different from the one
it hides on its far side. The nearside is dominated by the lunar mare -
the vast, dark-colored remnants of ancient lava flows. The
crater-pocked far side, on the other hand, is virtually devoid of
large-scale mare features. Why the two sides are so different is one of
the Moon's most enduring mysteries.
Now, researchers have a new explanation for the two-faced Moon - one
that relates to a giant impact billions of years ago near the Moon's
south pole. A new study shows that the impact that formed the Moon's
giant South Pole-Aitken (SPA) basin would have created a massive plume
of heat that propagated through the lunar interior. That plume would
have carried certain materials - a suite of rare-Earth and
heat-producing elements - to the Moon's nearside. That concentration of
elements would have contributed to the volcanism that created the
nearside volcanic plains. (4/8)
New Message Prepared for Sending to

An updated, binary-coded message has been developed for transmission to
extraterrestrial intelligences in the Milky Way galaxy. The proposed
message includes basic mathematical and physical concepts to establish
a universal means of communication followed by information on the
biochemical composition of life on Earth, the Solar System's
time-stamped position in the Milky Way relative to known globular
clusters, as well as digitized depictions of the Solar System, and
Earth's surface.
The message concludes with digitized images of the human form, along
with an invitation for any receiving intelligences to respond.
Calculation of the optimal timing during a given calendar year is
specified for potential future transmission from both the
Five-hundred-meter Aperture Spherical radio Telescope in China and the

selected region of the Milky Way which has been proposed as the most
likely for life to have developed. (4/8)
