NASA is advancing its preparations for the return of humans to the Moon, targeting a landing in 2028, in collaboration with commercial lander providers Blue Origin and SpaceX. The agency has streamlined the designs and operational concepts of its future crewed lunar landers.
Redefined Mission Objectives
Since partnering with Blue Origin and SpaceX for crewed lunar missions, NASA has redefined its Artemis III mission to demonstrate docking capabilities between landers from both companies and the Orion spacecraft in low Earth orbit. In addition, the companies are developing crew and cargo versions of their landers for upcoming Artemis missions.
He emphasized the agency’s commitment to an energetic and proactive approach in achieving its goals.
Launch and Operations Overview
The Artemis astronauts will launch aboard the Orion spacecraft, which is set on the Space Launch System (SLS) rocket from NASA’s Kennedy Space Center in Florida. During each mission, a commercial lander will rendezvous with Orion, transporting two crew members to the Moon while the other two remain with Orion. To expedite the 2028 landing, the Artemis landers will now meet Orion in varying orbits dictated by each partner’s systems, rather than in a previously planned halo orbit around the Moon.
Both providers will conduct uncrewed demonstration missions with their landers prior to the crewed missions to ensure safety and operational readiness.
SpaceX’s Starship Operations
SpaceX is developing a method for in-space propellant transfer to fuel its Starship Human Landing System (HLS). The plan involves launching multiple Starships into low Earth orbit to create a “tanker” fleet that will refuel a depot Starship before its mission to the Moon. This revised approach will allow the Starship to rendezvous with Orion in Earth orbit and perform a trans-lunar injection burn to reach low lunar orbit efficiently.
The new operational framework aims to reduce propellant needs and shorten the time required for astronauts to return to Orion after lunar surface operations.
Blue Origin’s Blue Moon Strategy
Blue Origin intends to utilize a multistage rocket design for its Blue Moon Mark 2 Alpha Lander. Unlike prior plans, the lander will use three transfer stages, allowing quicker returns from the Moon to Orion. The design is based on existing hardware and is expected to maximize the performance of the SLS while minimizing propellant requirements.
Blue Origin will also leverage insights from previous robotic missions to enhance its lander operations and will conduct an uncrewed demonstration mission to validate its approach.
Future Landings and Astronaut Missions
NASA plans to determine which company will first deliver astronauts to the lunar surface based on the readiness of the landers. Initial missions will include approximately two hours of Moonwalks for astronauts to collect samples and test new spacesuit capabilities.
This year, NASA revised its contracts with both Blue Origin and SpaceX to align their human landing systems with the agency’s accelerated lunar mission goals. Now, both companies will play a role in the Artemis III mission without specific assignments to particular lunar landings.
Jeremy Parsons, NASA’s Artemis program manager, highlighted the collaborative efforts with Blue Origin and SpaceX to ensure a successful return of astronauts to the Moon by 2028. Enhancements to the development milestones by both companies will provide NASA with greater insight into their preparations, contributing to astronaut safety and mission success.
Through these efforts, NASA aims to establish a sustained human presence on the Moon, paving the way for future missions, including potential crewed missions to Mars.
