China is launching a moon mission to find water ice

China is launching the Chang'e-7 mission to search for water ice on the moon. The mission will test new methods for lunar exploration, including an orbiter, lander, rover, and hopper. The hopper is designed to navigate through difficult terrain and enter craters where sunlight never reaches. The mission is expected to launch in August 2026, though a recent rocket failure has caused some uncertainty. The mission aims to determine where water ice is located, its form, and its concentration, and whether it can be accessed. This marks a shift from simply exploring the moon to determining if its resources can be used. The mission is part of China's lunar program, named after the ancient Chinese goddess of the moon, and uses the Queqiao-2 relay satellite for communication.

• The mission will land on or near an illuminated ridge close to Shackleton crater in the lunar south pole's Aitken region.
• The hopper is designed to leap over broken terrain and descend into craters where sunlight never reaches.
• The mission will use the already operational Queqiao-2 infrastructure for communication.

Other countries are also pursuing similar objectives. The United States is using its Commercial Lunar Payload Services (CLPS) program to develop a lunar marketplace, while China is focusing on coordinated state missions. NASA's Artemis program aims to support sustained lunar exploration, but its approach differs from China's. The mission highlights the challenges of lunar exploration, including the need for autonomous navigation, communications, and accessing resources in permanently shadowed areas. The South Pole is a key target, but the mission's success will depend on the ability to reach and operate in such environments. The mission is part of a broader effort to understand how to live and work on the moon, with future plans for crewed exploration and the International Lunar Research Station.
