The U.S. is once again trying to beat another nation to landing astronauts on the moon, and NASA officials and U.S. lawmakers say the stakes are even higher than they were in the 1960s.
AIAA Aerospace America story by Leonard David and Cat Hofacker explore the implications of this 21st century space race.

China’s next robotic explorer of the Moon – Chang’e-7 – is now at the Wenchang Spacecraft Launch Site in the southern island province of Hainan.
To be launched in the second half of this year, the China Manned Space Agency (CMSA) added that pre-launch tests will begin shortly.
According to China Central Television (CCTV), the Chang’e-7 mission aims to achieve several key technological breakthroughs, such as:
- A high-precision soft landing on the lunar surface
- Walking with its legs
- Leaping across the lunar surface
- Exploration of permanently shadowed craters

“The mission will adopt an integrated exploration approach, combining orbiting, landing, roving, and hopping, to survey the environment and resources of the lunar south pole, while also carrying out international cooperation,” added CCTV.

As the four-person Artemis II crew heads back to Earth, there’s a heavy breathing, nail-bitter ahead.
It is a wait-a-minute moment regarding the Orion spacecraft heat shield.
The high-speed, safe return to Earth from lunar distance of the Artemis II crew depends on the thermal protection system of Orion’s crew module. It must endure blistering temperatures to keep crew members safe.

However, following the flight of the uncrewed Artemis I lunar flight test in late 2022, it was found that ablative thermal protective material had unexpectedly chipped away from the Orion heat shield during its plunge through Earth’s atmosphere.

In 2024, NASA’s Office of Inspector General (OIG) issued a report – “NASA’s Readiness for the Artemis II Crewed Mission to Lunar Orbit” – calling attention to the heat shield issue.

Post-flight analysis
In a post-flight analysis of the Artemis 1 heat shield, NASA identified more than 100 locations where ablative thermal protective material was liberated during its speedy reentry.
NASA, along with contractors and an independent review team, an investigation was launched to establish the technical cause of the issue. An analysis was done, including over a 100 tests at unique facilities across the country.
Arc Jet Complex at NASA’s Ames Research Center in California’s Silicon Valley has been used to study unexpected heat shield issues found after Orion capsule’s Artemis I flight in 2022.

That extensive analysis, determined the heat shield on Artemis I did not allow for enough of the gases generated inside a material called Avcoat to escape, which caused some of the material to crack and break off.

Four astronauts have been selected for NASA’s Artemis II mission: Commander Reid Wiseman, pilot Victor Glover, mission specialist Jeremy Hansen from the Canadian Space Agency, and mission specialist Christina Koch from NASA.

The Artemis 2 quartet will be the first humans to get an up-close look at the Moon in more than 50 years.
That eye-full view has not been possible since the Apollo 17 astronauts departed the Moon back in 1972, now over 50 years ago!
A lunar observations campaign for the Artemis II crew has been plotted out, becoming the first humans to survey certain areas of the Moon’s far side as they speed by.
The four-person crew — NASA astronauts Christina Koch, Reid Wiseman, Victor Glover, and Canadian Space Agency astronaut Jeremy Hansen – will snag images, make observations, and detail their views via crew tablets and crew-to-Earth communications.

The Planetary Society urges Congress to reject historic cuts to NASA, again.
They have issued the following statement in response to the release of the FY 2027 top-line budget request for NASA, which would cut the agency by 23% and slash the Science Mission Directorate by 47%, from $7.25 billion to $3.9 billion.

A cinematic shot for the mind. Steven Spielberg’s Disclosure Day movie, set for release this June.

For sure the truth is reportedly out there. But in the case of flying saucers and unidentified anomalous phenomena what’s truly going on seems elusive to down-to-Earth explanation.
“The appetite for disclosure is likely to never be satisfied,” explains one expert.
But “disclosure” — in whatever form it takes — could indeed ignite a possible powder keg of implications.
Likely to strike a match to an explosive, eye-opening encounter with the truth is Steven Spielberg’s Disclosure Day movie, set for release this June.
Space.com reached out to a diversity of experts on the topic, obtaining a wide swath of swing and sway.

On the Horizon: Three Science and Technology Trends That Could Affect Society.
The Government Accountability Office (GAO) examined how these three technologies could evolve over the next decade. These transformative technologies are trending toward maturity and may need congressional attention over the next 10 years.
These technologies are:
- Neural implants for human augmentation.
- General purpose robots.
- Orbital debris removal technologies.
Orbital debris
Image credit: GAO
GAO reports that there are more than 15,000 pieces of orbital debris currently tracked, with more than a million pieces that are too small to track but can still damage satellites and other spacecraft that provide important services.
Technology is in development to actively remove, relocate, or repurpose large, non-tumbling debris. This could reduce the risk of a catastrophic cascade of collisions, but would not eliminate it because small or tumbling debris constitute the vast majority of dangerous debris.
Legal difficulties
Further development and use of novel technologies may be hampered by possible legal difficulties posed by the Outer Space Treaty.

Policymakers could consider a variety of options, including supporting targeted research to fill technological gaps or initiating legal analyses to develop solutions to legal difficulties.
GAO is not making recommendations but has identified several policy considerations for the Congress and others to weigh as these technologies continue developing.

Once the Artemis II crew is beyond the defensive environments of Earth’s atmosphere and magnetic field, they are subject to space radiation.
While en route to and from the moon, the Artemis II crew will be vigil, eyeing radiation monitoring detectors, listening for caution and warning alarms, and they would be outfitted with active dosimeters – a device for measuring and checking exposure to doses of radiation, such as X-rays or gamma rays.
Hot spot
The Artemis crew riding in their Orion spacecraft is relatively highly shielded. However, dealing with a worrisome solar event, Artemis flight rules would have the astronauts establish a shelter utilizing central stowage bays emptied of contents.
Tucked inside their Orion spacecraft, the Artemis II crew is seen in a pre-launch rehearsal.

Doing so would create a lower dose region within capsule confines. Stowage from the central bays would be moved to a known “hot spot” within Orion, to help reduce the dose rate exposure of the four-person crew. “
“If an event is particularly bad,” explains one expert, “there are some places in the capsule, such as storage bays and down by the toilet, that the crew can go to.”
