GM and Lockheed Martin's New Lunar
Rover, Rendered (Source: Motor Trend)
We're going back to the moon and General Motors is coming along, too.
Just as it did with Boeing back in the 1960s, GM is teaming up with the
aerospace experts at Lockheed Martin for the newest versions of the
moon buggy. This time, however, much of the technology used in these
buggies are coming from the same Ultium EV tech used in the GMC Hummer
and Chevrolet Silverado EV trucks.
Fortunately, technology has taken some great leaps and bounds since
Apollo 17. According to GM back in May of 2021, these next-generation
lunar rover vehicles are being designed to drive even farther distances
to support the first excursions of the Moon's south pole. These new
LRVs will also need better technology beyond their capacities as the
south pole is dark, making it much colder with much more rugged terrain
and the sunlit surfaces the Apollo missions landed in.
Fortunately, GM's Ultium technologies will most likely help create the
drive and battery packs these new rovers need. These new rovers will
also be autonomous, allowing them to launch prior to the human
landings. This is needed to help prepare for "commercial payload
services and enhance the range and utility of scientific payloads and
experiments" according to GM. Click here.

It’s Time for a Global Ban on
Destructive Antisatellite Testing (Source: Scientific American)
Although the prospects of a new multilateral treaty banning the
existence of space weapons are dim, there are other things that can be
done to minimize the dangerous consequences of these weapons. First and
foremost, the countries that are developing and testing such
weapons—China, India, Russia, and the United States—can unilaterally
declare a moratorium on further testing that creates orbital debris.
Doing so would send a strong signal to the international community that
they are committed to the long-term sustainability of space and for
delegitimizing the testing of these weapons against satellites.
Second, all countries should participate in and contribute to the OEWG
on space threats to discuss how to move towards a global ban on
destructive ASAT testing. Countries should come to the table with ideas
for addressing other pressing threats to space security. This includes
nonconsensual close encounters with another country’s satellites and
attempts to disrupt satellite operations by targeting them with
ground-based lasers. Although less obviously threatening than kinetic
attacks where a satellite is physically destroyed, such acts are
increasing in frequency and could inflame tensions, potentially leading
to misperceptions or mistakes that then spark actual armed, hostile
conflict in space. (1/14)
No Evidence of Life in Mars Meteorite
Found in Antarctica (Source: Orlando Sentinel)
A 4 billion-year-old meteorite from Mars that caused a splash here on
Earth decades ago contains no evidence of ancient, primitive Martian
life after all, scientists reported Thursday. In 1996, a NASA-led team
announced that organic compounds in the rock appeared to have been left
by living creatures. Other scientists were skeptical and researchers
chipped away at that premise over the decades, most recently by a team
led by the Carnegie Institution for Science’s Andrew Steele.
Tiny samples from the meteorite show the carbon-rich compounds are
actually the result of water — most likely salty, or briny, water —
flowing over the rock for a prolonged period, Steele said. The findings
appear in the journal Science. During Mars’ wet and early past, at
least two impacts occurred near the rock, heating the planet’s
surrounding surface, before a third impact bounced it off the red
planet and into space millions of years ago. The 4-pound rock was found
in Antarctica in 1984. (1/13)
Using High Temperature Composites For
Sustainable Space Travel (Source: Space Daily)
On the ground, sound waves travel at around 340 metres per second. An
aircraft is Supersonic when it exceeds the speed of sound. Hypersonic
speed is more than five times the speed of sound - or 'Mach 5' - which
is just over 6,000 kilometres per hour. At Mach 5 and above, friction
caused by molecules flowing over the hypersonic aircraft can generate
temperatures in excess of 2000 Celsius. Suffice to say that
Brisbane-based aerospace engineering start-up, Hypersonix Launch
Systems, is choosing its materials to cope with these extremes.
Founded in 2019, Hypersonix Launch Systems aims to provide sustainable
satellite launch services from Australia using hypersonic scramjet
technology. In a short time, and in the shadow of the pandemic, the
Hypersonix team of close to 20 aerospace engineers and material
specialists has developed reusable scramjet engine technology for
engines that are powered by sustainable green hydrogen fuel. (1/14)
NASA, White House Initiative to Spur
Entrepreneurial Spirit of HBCU Scholars (Source: NASA)
NASA and the Department of Education are collaborating to enhance the
federal Historically Black Colleges and Universities (HBCU) Scholar
Recognition Program using NASA entrepreneurial expertise. Beginning in
2022, a NASA pitch competition for students at higher education
institutions will officially become part of the HBCU Scholar
Recognition Program, part of the White House Initiative on Advancing
Educational Equity, Excellence, and Economic Opportunity. The
competition will be a small-scale version of NASA’s Minority University
Education and Research Program (MUREP) Innovation and Tech Transfer
Idea Competition (MITTIC). (1/12)
