Lunar caves would provide a temperate, stable, and safe thermal environment for long term exploration and habitation of the Moon.
Indeed, people could potentially live and work in lunar pits and caves with steady temperatures in the 60s.
That’s the bottom line from researchers at the University of California, Los Angeles (UCLA).
Tyler Horvath, a UCLA doctoral student in planetary science, led the new research recently published in the American Geophysical Union’s Geophysical Research Letters. The research team also included UCLA professor of planetary science David Paige and Paul Hayne of the University of Colorado Boulder.

Desirable habitat
“For long term colonization and exploration of the Moon, pits may provide a desirable habitat: they are largely free from the constant threats of harmful radiation, impacts, and extreme temperatures,” states the paper. “Thus, pits and caves may offer greater mission safety than other potential base station locales, providing a valuable stepping stone for sustaining human life beyond Earth.”
Since the discovery of pits on the Moon by the Japan Aerospace Exploration Agency (JAXA) SELENE spacecraft in 2009, there has been interest in whether they provide access to caves that could be explored by rovers and astronauts.

Prominent pit
Using data from the Diviner instrument aboard the Lunar Reconnaissance Orbiter (LRO), which has been continuously measuring the temperature of the lunar surface for over 11 years, the researchers methodically characterized the environment of one prominent pit located in Mare Tranquillitatis.

The pit’s thermal environment is more hospitable compared to anywhere else on the Moon, with temperatures varying minimally around a comfortable 17°C (or 63° F) wherever the Sun does not shine directly, explains the research paper.
“Humans evolved living in caves, and to caves we might return when we live on the Moon,” said Paige in a UCLA press statement. Paige leads the Diviner Lunar Radiometer Experiment.
Horvath and Paige are science team members for a new lunar-bound thermal camera led by Paul Hayne named the Lunar Compact Infrared Imaging System (L-CIRiS) which will head to the lunar south pole in late 2023 to get the first ground-based thermal images.

Increasing attention is being paid to the repercussion of rocket launches and space debris reentries on Earth’s fragile atmosphere, coupled to impacts on global climate and stratospheric ozone.
Exacerbating the situation is the rise of worldwide launch rates and the hurling of mega-constellations of satellites into Earth orbit. Then there’s the associated clutter of deceased spacecraft, discarded booster stages, and countless pieces of human-made refuse, from solid rocket motor effluents to stray nuts and bolts, tiny paint chips and droplets bubbling out of spacecraft coolant systems.

In short, it’s a heavenly mess – with long-term consequences.
The state of affairs has already been characterized by orbital debris experts as a “tragedy of the commons.”

China’s Tianzhou-3 cargo craft re-entered the atmosphere “in a controlled manner” Wednesday, reports the China Manned Space Agency (CMSA).
Meanwhile, all eyes are on the “uncontrolled” re-entry of the hefty Long March-5 rocket body, now predicted to fall to Earth July 31 ± 22 hours, according to re-entry experts at The Aerospace Corporation. This Long March-5 leftover hurled the Wentian, the first lab module of China’s space station.

As for the Tianzhou-3 cargo craft, it was launched on September 20, 2021, delivering roughly 6 tons of supplies to the in-construction station site. While in orbit, the cargo craft conducted two rendezvous and docking operations with the combination of the Tianhe core module, and carried out a test flight circling the space station.
Space technology tests
After its separation from the Tianhe combination on July 17, Tianzhou-3 carried out space technology tests, accumulating important experience for the in-orbit construction as well as the operation and management of the space station, according to a China Central Television (CCTV) report.

The Tianzhou-3 cargo craft flew independently during the rendezvous and docking between the Wentian lab module and the Tianhe core module. If any failure occurred during the docking process, Tianzhou-3 would have re-docked with the space station to provide living space for the astronauts, CCTV noted.
The CMSA explained that, as for the demise of the cargo vehicle, most of the spacecraft’s components burned up during re-entry, and a small amount of its debris fell into the scheduled safe waters.

There is promising new work underway to pursue a deep space robotic interstellar mission. An Interstellar Probe venture can capture a unified view of our heliosphere, out into nearby interstellar space.
All of that sounds exceedingly lofty, ambitious, and tough-to-do.
But there’s no need to wait for new technology say advocates – it’s here, and one booster of choice for the mission could be NASA’s Space Launch System (SLS).
“It isn’t about where we are going. It’s about the journey out there. And it is a journey now long overdue,” says one leading advocate.

The first lunar mission of the Korean Aerospace Research Institute is slated for an upcoming SpaceX Falcon 9 boost.
The Korea Pathfinder Lunar Orbiter, KPLO for short, is viewed as the first step of the country’s deep space agenda that includes a future first robotic landing onto the moon by 2030, as well as a sample collecting asteroid mission.
In May of this year, the KPLO was officially named “Danuri” – a blend of two Korean words for moon and “nurida” that means enjoy.

Launched on Sunday, the lab module flew to the station construction site, a process that took roughly 13 hours, according to the China Manned Space Agency (CMSA).
It was the first time that China’s two 20-ton-level spacecrafts conducted rendezvous and docking in orbit, and also the first time that a space rendezvous and docking were carried out during the astronauts’ in-orbit stay in the space station, the CMSA said.

Experiment racks
Like the Tianhe, the Wentian lab module is also equipped with living facilities for the astronauts, including three sleeping areas, a toilet and a kitchen. It has an airlock cabin which will become the main exit-entry point for extravehicular activities (EVAs) once active, replacing the role now played by the Tianhe docking hub.
The astronauts are slated to conduct in-orbit work such as the attitude control of the combination of the space station, small mechanical arm crawling and the test of the complex of big and small arms.
They will also use the airlock cabin and the small mechanical arm of Wentian to carry out extravehicular activities.
Station complete is set for year’s end.

Wentian’s main role is hosting experiment racks for science experiments, while also providing backups to the life support and control functions of the core module that was launched in April 2021.
Mengtian, the final component of the space station, is scheduled to arrive in October.
Crew handover
The new crew facilities will allow China to perform a first crew handover. This will take place when the current Shenzhou-14 crew — commander Chen Dong and co-astronauts Liu Yang and Cai Xuzhe — greet three new astronauts aboard Shenzhou-15 in December.
The fully-built Tiangong (Heavenly Palace) station will then host six astronauts for a period of days.
