NASA to Push Back moon Mission
Timelines Amid Spacecraft Delays (Source: Reuters)
NASA is set to delay its next few missions to the moon under a key
program as technical hurdles mount with the various spacecraft it
intends to use to get there, according to four people familiar with
NASA's plans. The U.S. space agency is expected to announce the plans
on Tuesday after spending months tracking progress with contractors and
considering changes to the Artemis program, a multi-billion dollar
effort that includes returning the first astronauts to the moon since
the last Apollo mission in 1972. (1/8)
Eugene Shoemaker Is The Only Human To
Be Buried On The Moon (Source: IFL Science)
Despite controversy, human remains are on their way to the Moon today,
after Space burial firm Celestis, which promises to launch the remains
of loved ones into space, purchased space on board private firm
Astrobotic's Peregrine lunar lander. The mission has been criticized by
the Navajo Nation (amongst others) for ignoring the sacred position the
Moon has in many indigenous cultures, with the President of the Navajo
Nation describing it as a “desecration of this sacred space.”
Surprisingly, though this is not the first commercial mission to place
remains on the lunar surface; there are already human remains "buried"
on the Moon. They belong to Eugene Shoemaker, whose ashes were launched
to his final resting place by Celestis on January 6, 1998. Twenty-eight
grams (1 ounce) of Shoemaker's ashes were sent on board NASA's Lunar
Prospector, inside a small vacuum-sealed polycarbonate capsule. (1/8)

Far above the planet, thousands of satellites are orbiting Earth. Some
are taking high-resolution photographs and beaming them back to ground
stations, allowing companies like San Francisco-based Planet Labs to
count how many ships are in a port. The spate of viral satellite images
of Evergreen Marine’s Ever Given, grounded in the Suez Canal in March
2021, cemented the importance of satellites for tracking and
documenting the global shipping fleet.
Other satellites provide television and phone service and,
increasingly, Internet access to remote corners of the planet. More and
more, these spaceborne sentinels are linking up with the maritime
sector. CMS began installing Starlink on ships in 2022. Litt, who
already had Starlink at his house, was asked by Maersk Line if his
company could put it on a ship, and the first installation occurred in
May of 2022. That first ship ended up becoming a test platform for
Starlink, whose engineers set sail with CMS for a week while they
performed operational and functional tests. (1/7)
Private Moon Lander Peregrine Is
Already in Big Trouble (Sources: Gizmodo, Space News)
“Unfortunately, it appears the failure within the propulsion system is
causing a critical loss of propellant,” the company noted on X. “The
team is working to try and stabilize this loss, but given the
situation, we have prioritized maximizing the science and data we can
capture.” What’s more, and as a result of this apparent critical
failure, Astrobotic is now brainstorming “alternative mission profiles”
for Peregrine in an attempt to salvage the project and explore
different avenues for achieving at least some objectives despite the
setback."
Astrobotic said late Monday that those thrusters will run out of fuel
in about 40 hours, after which it will start to tumble and lose power,
effectively ending the mission. That rules out a landing on the moon,
with Astrobotic hoping to instead operate the spacecraft "as close to
lunar distance as we can" before losing power. Astrobotic was carrying
20 payloads from NASA and other customers on Peregrine, the first in a
series of commercial lander missions backed by the agency. (1/8)
Moon Mission Carries Sports Drink and
Human Remains - is This Compatible with Science? (Source: Sky
News)
NASA hopes the innovation of tech start-ups will bring down the costs
of transporting equipment to the moon. It paid Astrobotic $108m (£85m)
to put five experiments on the lunar surface. That's a bargain. It's
also a gamble. Astrobotic's shed-sized lunar lander, called Peregrine,
is untested, as was the rocket that launched it towards the heavens.
But while NASA celebrates the value for money from involving commercial
know-how, there is a cost. To make the sums add up, Astrobotic has sold
space to other companies with aims that are far from scientific. One
company is sending a can of its sports drink in a powdered form so
future astronauts can mix it with lunar water. And even more
controversially there are capsules containing cremated human remains
and DNA. That's angered the Navajo Nation of indigenous Americans, who
regard the moon as sacred.
Even those with no spiritual connection to the moon might feel a little
uneasy over commercial missions. For decades it has been a giant
science lab - a time capsule that could tell us something about the
solar system's history - and in future it could be a location for new
radio telescopes that could peer into space without interference from
Earth. (1/8)
New Dark Energy Measurements
(Source: The Conversation)
In a new study soon to be published in the Astronomical Journal, we
have measured the properties of dark energy in more detail than ever
before. Our results show it may be a hypothetical vacuum energy first
proposed by Einstein – or it may be something stranger and more
complicated that changes over time. Since those initial measurements,
we’ve been using supernovae and other probes to measure the nature of
dark energy. Until now, these results have shown the density of dark
energy in the universe appears to be constant.
Finally, after more than a decade of work and studying around 1,500
Type Ia supernovae, the Dark Energy Survey has produced a new best
measurement of w. We found w = –0.80 ± 0.18, so it’s somewhere between
–0.62 and –0.98. This is a very interesting result. It is close to –1,
but not quite exactly there. To be the cosmological constant, or the
energy of empty space, it would need to be exactly –1. (1/8)
NASA Just Spotted an Exploded Star
Blasting Vital Elements Into Space (Source: Mashable)
Around 3,000 years ago, a star 15 times bigger than our sun exploded.
Now, scientists are watching it blast valuable elements into space.
Astronomers have a powerful new observatory orbiting Earth, the Japan
Aerospace Exploration Agency-led XRISM (X-ray Imaging and Spectroscopy

unprecedented view of this exploded star, now called "supernova remnant
N132D," located some 160,000 light-years away.
Massive stars forge elements deep inside their hot, pressurized cores,
and can also create elements during a violent stellar blast that occurs
when they run out of fuel and collapse. The XRISM observatory picked up
evidence of iron, calcium, sulfur, silicon, and argon. (1/6)

Examining One of the Largest Stars in
the Milky Way as it Fades From View (Source: Phys.org)
Astronomers have captured the first close-up images of a massive star
known as RW Cephei that recently experienced a strange fading event.
The images are providing new clues about what's happening around the
massive star approximately 16,000 light years from Earth. Scientists
were surprised last year by the fading of the enormous star, which is
an example of a "cool hypergiant," a star that has grown to huge
dimensions as it approaches the end of its life. RW Cephei is so large
that if it were placed at the sun's location, its outer layers would
reach beyond the orbit of Jupiter.
Despite its huge size, RW Cephei is so far away that it appears as a
pinpoint even using the largest of conventional telescopes. To see the
star close up required the remarkable abilities of the Center for High
Angular Resolution Astronomy (CHARA) Array telescopes. The final
pictures show a star convulsed by motions in its outer layers that
create fainter and brighter patches across its surface. Furthermore,
the appearance changed significantly over the 10-month period of
observations that coincided with the transition from its faintest state
to a slow recovery toward its former brightness. (1/8)

One crucial area where new missions and enabling technologies are
needed is the long-duration storage of cryogenic propellants in various
space environments; relevant propellants include liquid Hydrogen (LH2)
for high specific impulse Nuclear Thermal Propulsion (NTP) which can be
deployed in strategic locations in advance of a mission. Such LH2
storage tanks could be used to refill a crewed Mars Transfer Vehicle

We propose a breakthrough mission concept: a cryogenic liquid storage
depot capable of storing LH2 with ZBO even in the severe and
fluctuating thermal environment of LEO. Our innovative storage depot
mission employs thin, lightweight, all-solid-state panels attached to
the tank’s deep-space-facing surfaces that utilize a long-understood

Cooling (ELC) to reject heat from cold solid surfaces as
non-equilibrium thermal radiation with orders of magnitude more power

Stolen and Destroyed Moon May Have

Venus is truly an odd twin of Earth. Despite its similar size, the
planet has such a thick, hot atmosphere that it would crush you and
cook you if you were to stand on its surface. And the space oddities
don’t end there. As all the other planets spin anticlockwise on their
axes, Venus spins clockwise. The reason is unclear, but a new proposal
sees Venus capturing and then destroying a moon.
Researchers want us to cast our eyes back to near the beginning of the
Solar System. It was a time when the rocky planets had assembled most
of their mass, but there were still plenty of building blocks hanging
about. A planetesimal could have been captured by Venus. The research
duo looked at hundreds of thousands of simulations and found scenarios
that they deem both possible, and with the power to explain the
properties of Venus today. First of all, the moon capture would have
been retrograde. This means that was going around Venus in the opposite
direction.
The assumption is that Venus at that point was spinning in the same
direction as the other planets. The captured moon in the scenario was
kept thanks to the presence of material around Venus that removed
orbital energy. (1/8)
