Do We Still Have the Right Stuff? (Source:
City Journal)
It’s an exciting time for space travel—or it should be. The space
industry’s second Golden Age has not captured the public imagination.
As the rockets climb toward the heavens, in fact, much of the media and
political commentary has been startlingly negative. Oligarchs and their
toys! What about world hunger? We need a wealth tax. What about climate
change? We need a wealth tax. What about universal health care? Time
for a wealth tax!
Apathy, cynicism, bitterness: Why is this the way so many Americans,
especially among the progressive elite, react to such stunning feats of
imagination, perseverance, and ingenuity? The response suggests a
stunted view of the human condition, and it raises an unsettling
question: Does the United States still have what it takes to lead the
world into space? Do we still have the right stuff? Click here.

How Could The Big Bang Arise From
Nothing? (Source: IFL Science)
Some cosmologists believe a previous, cold dark empty universe like the
one which lies in our far future could have been the source of our very
own Big Bang. Quantum field theory tells us that even a vacuum,
supposedly corresponding to empty spacetime, is full of physical
activity in the form of energy fluctuations. These fluctuations can
give rise to particles popping out, only to be disappear shortly after.
This may sound like a mathematical quirk rather than real physics, but
such particles have been spotted in countless experiments.
The spacetime vacuum state is seething with particles constantly being
created and destroyed, apparently “out of nothing”. But perhaps all
this really tells us is that the quantum vacuum is (despite its name) a
something rather than a nothing. (12/9)
Life Might Have Been Possible Just
Seconds After the Big Bang (Source: Space.com)
Perhaps it's possible to have life without chemistry. It's hard to
imagine what these creatures might be like. But if we take our broad
definition — that life is anything subject to evolution — then we don't
need chemicals to make it happen. Sure, chemistry is a convenient way
to store information, extract energy and interact with the environment,
but there are other hypothetical pathways.
For example, 95% of the energy contents of the universe are unknown to
physics, literally sitting outside the known elements. Scientists
aren't sure what these mysterious components of the universe, known as
dark matter and dark energy, are made of.
Perhaps there are additional forces of nature that work only on dark
matter and dark energy. Maybe there are multiple "species" of dark
matter — an entire "dark matter periodic table." Who knows what
interactions and what dark chemistry play out in the vast expanses
between the stars? Hypothetical "dark life" may have appeared in the
extremely early universe, well before the emergence of the first stars,
powered and mediated by forces we do not yet understand. (12/10)
Henry Kissinger and the Birth of Space
Diplomacy (Source: The Hill)
Henry Kissinger, former national security advisor and secretary of
State, recently died at the age of 100 years. He was famous for the
opening of mainland China, the Paris Peace Accords that ended American
involvement in the Vietnam War and the negotiated end of the Yom Kippur
War between Israel and several Arab states.
Admired by some, reviled by others, he bestrode the last third of the
20th century like a colossus where foreign policy was concerned.
Kissinger also had a role in creating space exploration as a tool of
diplomacy. The strategy fit neatly into the policy of détente that he
and President Richard Nixon devised to manage the Cold War between the
United States and the Soviet Union. (12/10)
Artemis' Next Giant Leap: Orbital
Refueling (Source: Hackaday)
Both SpaceX and Blue Origin have essentially the same problem: their
landers, when you include the propellant they’ll need to land on the
Moon and lift back off again, are simply too heavy to launch. Both
companies are developing heavyweight boosters to get their respective
landers out of Earth’s gravity well and into low Earth orbit, but
that’s the best they can do. So how will they get astronauts to the
Moon?
While the techniques differ slightly, both companies will need to load
their landers with the propellants necessary to complete the missions
while they are already in space. And in both cases, the lander’s human
crew wouldn’t launch from Earth until their ride to the lunar surface
is fueled up and waiting for them. If Artemis is going to return
astronauts to the Moon, this is a problem that needs to be solved
quickly.
Despite the fact that both Blue Origin and SpaceX have hung the success
of their respective lunar landers on the ability to quickly and safely
refuel them while in orbit, there’s simply no precedent for such an
operation. Studies so far have focused on refueling small satellites,
using relatively simple monopropellants like hydrazine. But topping off
the tanks on Starship or Blue Moon will mean autonomously moving
hundreds of tons of cryogenic liquid oxygen, methane, and hydrogen
between spacecraft. The couplings, pumps, piping, valves, and
insulation required to facilitate that sort of propellant transfer have
never been tested in space and could take many iterations to perfect.

Rail Industry Urged to Consider Safety
Risks of Space Weather (Source: Lancaster University)
Train accidents could be caused by solar storms switching signalling
from red to green according to new research examining the impact of
space weather. Solar storms can trigger powerful magnetic disturbances
on Earth, creating geomagnetically induced currents (GICs) which could
potentially interfere with electricity transmission and distribution
grids.
A team led by PhD researcher Cameron Patterson and Professor Jim Wild
from Lancaster University modelled how GICs flowed through the track
circuits of AC electrified lines powered with overhead cables. Using
two routes - the Preston to Lancaster section of the West Coast Main
Line, and the Glasgow to Edinburgh line – the team modelled how GICs
induced in the rails could cause rail signalling to malfunction. (12/11)
GHGSat to Measure Greenhouse Emissions
at Every Industrial Site, Worldwide, Every Day (Source: Spectra)
GHGSat, the global leader in greenhouse gas emissions intelligence,
today announced plans to measure methane and carbon dioxide emissions
at every major industrial site worldwide, every day, by 2026. These
will include oil & gas production and storage facilities, waste
management centres, coal mines, power stations, steel mills, aluminium
smelters, chemical plants and cement works. The goal is to provide
accurate, independent and site-specific data on a global basis, so
industrial operators, governments and other stakeholders can better
understand, control and reduce emissions.
GHGSat will take over 2 million facility measurements this year using
its unique fleet of 12 space-based high-resolution sensors - the
biggest greenhouse gas monitoring constellation in the world. The
company also provides data to the United Nations, NASA, the UK Space
Agency and the European Space Agency. GHGSat’s monitoring ambition
leans on the rapid expansion of its constellation and deployment of new
proprietary technologies and combines their measurements with
third-party information in order to cover c.5m+ industrial locations
worldwide. (12/3)
Rethink the Mars Program
(Source: Space News)
NASA’s robotic Mars exploration program is in crisis. A recent review
of the plan of its flagship Mars Sample Return (MSR) mission pegged its
cost at $10 billion, a price tag that threatens to preclude funding any
other exploration missions to the Red Planet for the next decade and a
half. While the decadal plan issued by a National Academy of Science
committee identifies the MSR mission as the top priority for NASA’s
Mars exploration program, given the cost and schedule numbers now
available, it is time for the rest of us to question whether the
program of record still makes sense.
Let us consider the alternative. For the same $10 billion now projected
to be spent on the MSR mission over the next 15 years, we could send 20
missions averaging $500 million each in cost. These could include
landers, rovers, orbiters, drillers, highly capable helicopters, and
possibly balloons or other more novel exploration vehicles as well.
Instead of being limited to one exploration site, these could be
targeted to 20 sites and carry a vast array of new instruments provided
by hundreds of teams of investigators from around the world. (12/7)

The Race to the Moon: The Urgent Need
for U.S. Innovation in Lunar Colonization (Source: LinkedIn)
Each day, the race for lunar colonization gains momentum, yet the U.S.
finds itself increasingly at risk of falling behind. The recent
collaboration between China and Russia in establishing a lunar base
underscores a pivotal moment: the U.S. must urgently innovate its
approach to lunar colonization or risk losing its position as a leader
in space exploration.
The International Lunar Research Station, a joint venture between
China's National Space Agency and Russia's Roscosmos, represents a
significant leap in lunar exploration. This partnership benefits from
China's advancements in bioregenerative life support systems (BLSS),
such as the Beijing Lunar Palace, and Russia's decades of space
exploration experience. Meanwhile, the U.S., having diverted funds from
life support research to the SLS/Orion transportation system, now faces
a daunting catch-up game.
To remain a key player in space exploration and reap the potential
economic and geopolitical benefits, the U.S. must prioritize the
development of innovative life support and colonization technologies
for the Moon. Click here.

Momentus' Failed Satellite Deployment
Questioned (Source: Space News)
Momentus said three satellites it launched last month failed to deploy,
but one of its customers thinks otherwise. Momentus said last week that
a problem with a third-party deployer likely prevented three cubesats
from deploying from the Falcon 9 upper stage during the Transporter-9
launch. The satellites would have been destroyed when the upper stage
reentered hours after launch. One of the customers affected, Lunasonde,
had earlier claimed its Picacho cubesat had deployed and unfurled its
antenna. Lunasonde now says that while telemetry suggests its cubesat
might not have deployed, it is still searching for it. The other
affected cubesats were from Oman and South Korea. (12/11)
