Manned lunar exploration missions are indeed steadily progressing, with several significant aspects:
1. NASA's Artemis Program
Objectives
Return humans to the Moon: The Artemis program aims to land the first woman and the next man on the lunar surface by 2025. This is a significant step in resuming human lunar exploration after the Apollo missions ended in 1972.
Establish a sustainable presence: NASA plans to build a lunar base near the Moon's south pole in the long term. The region is of particular interest due to the presence of water ice, which can be used for various purposes, such as providing drinking water for astronauts, and can be broken down into hydrogen and oxygen for use as rocket fuel.
Progress
Spacecraft development: The Orion spacecraft has been developed as part of the Artemis program. Orion is designed to carry astronauts on deep space missions, including to the Moon. It has successfully completed several test flights, such as the uncrewed Artemis I mission in 2022, which orbited the Moon and returned to Earth, demonstrating the spacecraft's capabilities for future crewed missions.
Rocket technology: The Space Launch System (SLS) has been developed to launch Orion and other payloads on lunar missions. The SLS is a powerful rocket that can provide the necessary thrust to send spacecraft on lunar trajectories.
2. China's Lunar Exploration Program
Objectives
Lunar scientific research: China's lunar exploration program, named Chang'e, focuses on conducting comprehensive scientific investigations of the Moon. This includes studying the lunar geology, topography, and the composition of the lunar surface.
Technology demonstration: The program also aims to demonstrate key technologies for lunar exploration and future deep space exploration, such as lunar orbit insertion, soft landing, and lunar rover operation.
Progress
Chang'e missions: China has achieved a series of successful lunar missions. Chang'e 3, launched in 2013, made China the third country to soft land on the Moon and deploy a lunar rover. Chang'e 4, in 2019, was the first mission to land on the far side of the Moon, providing valuable data about this previously unexplored region. Chang'e 5, in 2020, successfully returned lunar samples to Earth, which is a major accomplishment for lunar exploration.
3. International Collaboration
Future possibilities: There are also discussions about international collaboration in lunar exploration. For example, NASA has expressed interest in working with other countries, including commercial partners, on aspects of the Artemis program. This could include sharing technology, conducting joint scientific research, and potentially establishing a more inclusive lunar exploration effort.
