NASA has updated its list of potential landing sites for the next human visit to the moon, which is planned for 2026. The Artemis III mission will see the first crewed lunar landing since the Apollo era, and the plan is for astronauts to explore the moon’s South Pole region where there is thought to be water ice on the lunar surface.
NASA shared a list of 13 candidate landing locations for Artemis III in 2022, but has now updated its list to nine candidates. Some of these were on the list previously, while others have been added such as the Mons Mouton mountain and plateau, which is particularly interesting to scientists because the height of the mountain means that there are permanently shadowed regions nearby. These places, where sunlight never touches, are particularly good candidates when it comes to looking for water ice.
“The Moon’s South Pole is a completely different environment than where we landed during the Apollo missions,” said Sarah Noble, Artemis lunar science lead at NASA Headquarters, in a statement. “It offers access to some of the moon’s oldest terrain, as well as cold, shadowed regions that may contain water and other compounds. Any of these landing regions will enable us to do amazing science and make new discoveries.”
This image shows nine candidate landing regions for NASA’s Artemis III mission, with each region containing multiple potential sites for the first crewed landing on the moon in more than 50 years. NASAWhen choosing a landing site, NASA tries to find a balance between areas that are scientifically interesting and those that are safe and easier to land on. The site selectors also need to consider practicalities such as communications with Earth and what launch windows would be required to reach a site.
“Artemis III will be the first time that astronauts will land in the south polar region of the moon. They will be flying on a new lander into a terrain that is unique from our past Apollo experience,” said Jacob Bleacher, NASA’s chief exploration scientist. “Finding the right locations for this historic moment begins with identifying safe places for this first landing, and then trying to match that with opportunities for science from this new place on the moon.”
The location of water ice is particularly important for two reasons: firstly, as an object of scientific study, but also as a resource for lunar explorers. NASA has plans for long-term visits to the moon, counted in weeks or months rather than the days that have been the norm in the past, and this requires considerable resources to keep astronauts healthy. If the early missions can identify resources like available water ice, it could help sustain longer missions in the future.

Boeing Starliner lands safely back on Earth without its crew
After an unexpectedly long time spent in orbit, the Boeing Starliner spacecraft has returned safely to Earth after three months. Although it was designed to carry astronauts to and from the International Space Station (ISS), the spacecraft returned home without crew following a problem with its thrusters.
The Starliner landed in White Sands Space Harbor in New Mexico just after midnight ET on September 7, bringing to an end its first crewed test flight. Its reentry through the atmosphere went to plan, and it performed a parachute-assisted landing in the desert that was cushioned with airbags. However, during the return flight, there were more minor issues with its thrusters, including two of the 27 reaction control thrusters getting hotter than expected, and one thruster on the crew module that failed -- although it was covered by a redundant thruster.

Intuitive Machines to carry NASA experiments to the moon in 2027
Intuitive Machines, the company that earlier this year managed the first lunar landing by a commercial entity (partly successfully) will be returning to the moon with more NASA payloads. As part of NASA's CLPS (Commercial Lunar Payload Services) program, Intuitive Machines will design and build a lander to launch to the moon's south pole, and NASA will pay $117 million for it to carry six science payloads.
This is part of NASA's broader effort to embrace the burgeoning private space industry by becoming a customer of space companies rather than designing and building its own spacecraft. The aim is for Intuitive Machines to arrive at the moon's south pole in 2027, ahead of the Artemis missions that will see humans return to the lunar surface. The company will also be launching another lunar lander called Athena later this year, with a third launch planned next year as well.
