GAO: NASA Needs to Improve Artemis
Management as New Schedule Delays Likely (Source: Parabolic Arc)
NASA needs to strengthen its management oversight of the lunar landing
program to minimize delays and cost overruns as the space agency moves
beyond the Artemis I flight test scheduled for November 2021, according
to a new report from the Government Accountability Office (GAO). GAO’s
program review also found that schedule for the maiden flight of the
Space Launch System and second Orion spacecraft does not account for
delays resulting from the ongoing COVID-19 pandemic.
“Due in part to COVID-19, manufacturing delays, and remaining risks,
there is already risk that this new launch date will not be met. NASA
has successfully completed some key test events to evaluate readiness
to support the first uncrewed test flight, but complex SLS core stage
testing, integration of the SLS and Orion spacecraft, and final
integrated testing remain to be completed prior to the Artemis I
launch,” the report stated. GAO’s report and recommendations to NASA
are largely focused on improving program beyond the Artemis I mission,
which is focused on a lengthy automated flight of the Orion crew
vehicle. (1/4)
The Surface of the Moon is a Galactic
Time Capsule (Source: Space.com)
You wouldn't know it by looking at it, but the moon is a time capsule.
Its surface has been completely exposed to vacuum for almost 4.5
billion years; meanwhile, it has been soaked by particles from the sun
and beyond the solar system. Those particles remain, buried under the
lunar surface, providing a detailed record of the history of our solar
system and even our entire galaxy. It's all right there. We just need
to dig it up.
Back when the moon was molten it may have sported a temporary magnetic
field, but that's in the distant past. For all these billions of years,
the moon has been steadily soaking up solar wind particles, absorbing
them into its regolith. Faced with that nonstop onslaught, the regolith
has changed. The high-energy particles may have disrupted the chemical
composition of the lunar surface. Elements like potassium, which should
be found in abundance, seem to have been turned into other elements,
which then floated away.
The lunar dust has also been sunburnt: Even though each individual
particle is super tiny, the moon has no atmosphere and so no erosion,
leaving the same dirt to face the sun again and again. Each little
solar particle tears a microscopic hole in the dirt, so by studying
the structure of the regolith, we can see a record of the sun's
glare. (12/31)
SpaceX May Try to Catch a Falling
Rocket With a Launch Tower (Source: Ars Technica)
If SpaceX can design a launch tower arm, or pair of arms, to grab the
Super Heavy booster, it might be moved rather quickly back onto the
launch mount. Such a rocket might then—and this would require years of
refinement and experimentation—be rapidly inspected, refueled, and
launched again. Perhaps even within an hour, Musk said.
It is unclear whether this is even possible. But in theory, a Super
Heavy booster could descend under the power of a subset of its 28
engines, come very nearly to a hover, and arms from the launch tower
could extend to grab the booster. This does sound like a rather crazy
maneuver, but a few years ago so did dispatching an autonomous drone
ship into the Atlantic Ocean to catch falling rockets.
Whether this all works out remains to be seen. SpaceX has tried many
things in the past in regard to rockets only to discard these ideas.
This is one of the keys to success for Musk and his leadership style.
He asks his employees to do nearly impossible things—such as building a
fully reusable orbital launch system. And then he gives them the
freedom to experiment and, sometimes, to fail. (1/4)
How the Biden Administration Can Make
DoD an Innovation Powerhouse (Source: FNN)
DoD needs to seriously dig into its efforts to harness innovation,
instead of just dipping in a toe, if it wants to continue to stay ahead
of China and Russia. To do that, DoD has to start taking software
seriously, put bigger bets on contracting unconventional technologies
with nontraditional defense businesses and work on changing the culture
of the Pentagon from relying on legacy systems and old-guard defense
companies.
“You have to squint hard to see something that isn’t a legacy in DoD’s
acquisition plans. I’m not suggesting they’re all wrong, I’m asking
where are the new things that will get us ahead. That’s the innovation
dilemma of DoD. They’re still operating under the McNamara era in
1960s: contained cost, lifecycle management, etc.”
“We need to hold more competitions for the best technology and actually
reward the winners of those competitions,” Stephens said. “If you say,
‘We’re going to have a competition for some new piece of technology,
and here are like three exercises that we’re going to hold.’ At the end
of those three exercises, if you don’t give out a meaningful contract,
then people are going to start losing trust in your willingness to
actually reward people’s work. That’s highly problematic.” (1/1)
Preparing for “Earth to Earth” Space
Travel and a Competition with Supersonic Airliners (Source:

Commercial spaceflight companies are preparing to enter a new market:
suborbital flights from one place to another on Earth. Aiming for fast
transportation for passengers and cargo, these systems are being
developed by a combination of established companies, such as SpaceX and
Virgin Galactic, and new ones like Astra. Technical and business
challenges lie ahead for this new frontier, and an important piece is
the coming wave of supersonic aircraft which could offer safer but
slower alternatives to spaceflight. These two different approaches
could face off in the 2020s to be the future of transportation on
Earth. Click here.

SpinLaunch to Expand at Spaceport
America (Source: Albuquerque Journal)
California-based SpinLaunch Inc. is expanding its operations at
Spaceport America in southern New Mexico, where it plans to test new
technology to literally fling rockets into space. The company already
built a $7 million, 10,000-square-foot facility at the Spaceport after
announcing plans last year to conduct all testing there on its new
technology. Now, the company is doubling down, with plans to hire an
additional 59 people and invest another $46 million over 10 years.
The state Economic Development Department will support the expansion
with $4 million in Local Economic Development Act funding, said EDD
Secretary Alicia J. Keyes. “SpinLaunch is part of a growing community
of businesses creating jobs and innovating new technologies at New
Mexico’s Spaceport America,” Keyes said in a statement. “We see the
state’s space cluster as an important economic driver to diversify the
economy with higher-paying jobs in southern New Mexico.”
SpinLaunch is headquartered in Long Beach, Califonia, where it operates
a 140,000-square-foot test and manufacturing facility. The company,
which launched in 2014, has raised about $80 million in venture
investment to date, including a $35 million round of funding in January
2020. SpinLaunch is developing a unique centrifuge system that rapidly
spins a rocket around on the ground until it reaches hypersonic speeds.
It then releases the vehicle like a catapult to hurl it to the edge of
space. (12/15)
Ten Companies Bid for NASA Small
Launch Vehicle Contract (Source: Space News)
A NASA small launch vehicle competition attracted bids from 10
companies, but half of them were effectively disqualified because of
deficiencies or other problems. NASA announced Dec. 11 it was awarding
contracts to Astra Space, Firefly Aerospace, and Relativity Space for
its Venture Class Launch Services (VCLS) Demo 2 program. The contracts,
with a combined value of $16.7 million, include one launch by each
company carrying clusters of cubesats as part of a NASA effort to help
demonstrate new small launch vehicles. NASA did not disclose the number
of bidders for the VCLS Demo 2 competition at the time of the contract
award.
It did, though, release a source selection statement Dec. 23 that
outlined the agency’s assessment of the proposals it received and why
it selected the three companies for contracts. Under terms of the VCLS
Demo 2 solicitation, companies had to submit proposals for one of two
distinct missions. “Mission One” would be a dedicated launch of 30
kilograms of cubesats to a 500-kilometer mid-inclination orbit.
“Mission Two” called for launching 95 kilograms of cubesats as a
primary payload, with 75 kilograms of cubesats going to one
sun-synchronous orbit at 550 kilometers and the other 20 kilograms to a
similar orbit but in a plane at least 10 degrees apart.
Seven companies submitted proposals for Mission One: Aevum, Astra,
Gloyer-Taylor Laboratories, Interorbital Systems, Phantom Space
Corporation, Phoenix Launch Systems and Relativity. Two submitted
proposals for Mission Two: Firefly Black, the government services arm
of Firefly Aerospace, and Momentus. A tenth bidder was Wagner Star
Industries, a startup that, according to its LinkedIn page, is
developing a “spaceplane drone.” (1/3)
A New Frontier is Opening in the
Search for Extraterrestrial Life (Source: Washington Post)
On Dec. 18, the world learned that Breakthrough Listen, a privately
funded search for extraterrestrial intelligence, had found its first
official candidate signal. The signal’s existence lit up the Internet.
Was BLC-1, as it’s called, finally our moment of contact? Breakthrough
Listen scientists, now hard at work on a paper about their findings,
were quick to explain that the answer was probably “no”: Given the
wealth of human-made radio signal interference out there, BLC-1 will
probably turn out to be of human origin.
Their preliminary conclusion, however, does not defuse the excitement
of BLC-1. The fact that there’s a candidate at all is cause for
celebration. That’s because something remarkable is happening in the
science of life and intelligence beyond Earth. The age of
“technosignatures” is dawning. NASA has been an essential part of this
recognition: At the behest of Congress, the space agency convened its
first meeting on what is now called “Technosignatures Science" in 2018.
In 2019, my colleagues and I were awarded NASA’s first-ever research
grant to study atmospheric technosignatures, and this year, NASA funded
two other technosignature studies. (12/31)
Solar Ring Mission Proposal: A New
Concept of Space Exploration (Source: SciTech Daily)
This concept for the first time proposes to deploy six spacecraft,
grouped in three pairs, in three elliptical orbits between the earth
and Venus around the Sun to observe and study the Sun and the inner
heliosphere in a full 360-degree perspective. The separation angle
between two spacecraft in each group is about 30 degrees, and that
between every two groups is about 120 degrees. Through this
configuration, the mission will be able to image the vast area from the
photosphere to the inner heliosphere with high resolution, and perform
the in situ measurements.
Three unprecedented capabilities will be established: (1) determine the
photospheric vector magnetic field with unambiguity, (2) provide
360-degree maps of the Sun and the inner heliosphere routinely, and (3)
resolve the solar wind structures at multiple scales and multiple
longitudes. With these capabilities, the Solar Ring mission aims to
address the origin of solar cycle, the origin of solar eruptions, the
origin of solar wind transients and the origin of severe space weather
events. (6/2/20)
Pace Steps Down From Space Council
(Source: Space News)
The executive secretary of the National Space Council, which led
development of that strategy and other space policies, has stepped
down. Scott Pace announced Thursday he was leaving government to return
to George Washington University, where he previously led its Space
Policy Institute. Pace's departure, while expected, comes as the future
of the council itself remains uncertain. The incoming Biden
administration has not stated if it will retain the council, which the
Trump administration reestablished in 2017 after a hiatus of nearly a
quarter-century. Some in the space community recommend that the Biden
administration keep the council to continue the work it did to
coordinate national space policy. (1/3)
Quasars Rip Across Galaxies Like
Tsunamis (Source: SciTech Daily)
Using the unique capabilities of NASA’s Hubble Space Telescope, a team
of astronomers has discovered the most energetic outflows ever
witnessed in the universe. They emanate from quasars and tear across
interstellar space like tsunamis, wreaking havoc on the galaxies in
which the quasars live. Using the unique capabilities of Hubble,
astronomers have discovered that blistering radiation pressure from the
vicinity of the black hole pushes material away from the galaxy’s
center at a fraction of the speed of light. The “quasar winds” are
propelling hundreds of solar masses of material each year. This affects
the entire galaxy as the material snowplows into surrounding gas and
dust. (1/1)
Does The Expanding Universe Break The
Speed Of Light? (Source: Forbes)
If you have no mass and you’re traveling through completely empty
space, there’s no other speed you’re allowed to move at; you must move
at the speed of light. And yet, if you think about how big the
observable Universe is, we know it’s grown to 92 billion light-years in
diameter in just 13.8 billion years. Moreover, by the time just one
second elapsed since the Big Bang, the Universe was already multiple
light-years across! How is this possible without breaking the laws of
physics?
If you want to understand what’s going on, you’re going to have to bend
your brain a little bit, because both things are simultaneously true:
the Universe really does grow in this fashion, and yet nothing can
travel faster than light. Let’s unpack how this happens. Click here.

Supercomputer Simulation Re-enacts the
Birth of the Moon (Source: TNW)
The formation of the Moon billions of years ago is cloaked in mystery.
Most astronomers believe the young Earth, still cooling off from its
formation, was struck by a mars-sized body called Theia, roughly 4.5
billion years ago. As the proto-Moon orbited Earth, it cooled, and
gathered debris from the surrounding region of space. At the time, the
Moon was much closer to Earth than it is today. Over billions of years,
gravitational forces between the Earth and the Moon resulted in our
planetary companion moving further away from our home world.
Researchers at Durham University developed supercomputer simulations,
showing how this ancient collision may have unfolded. The velocity of
Theia and the angle of impact affected the collision, as did the
rotational rate of the body. The team of investigators examined a wide
range of possible conditions, ranging from no spin to a quick rotation,
and from glancing blows to more direct impacts. Interestingly, when
simulations tested the effect of a non-spinning version of Theia, the
impact resulted in a satellite with roughly 80 percent of the mass of
the Moon. Adding just a small amount of spin resulted in a second Moon
in orbit around Earth. (1/3)
