NASA’s Artemis III mission is poised to mark a significant milestone in human space exploration. Scheduled for no earlier than summer 2027, this mission will see astronauts docking with both a Blue Origin lander and a SpaceX Starship lander in low-Earth orbit. The mission’s complexity and the intricate details surrounding it have sparked considerable interest and discussion within the space community.
In a recent announcement, NASA revealed the crew for the Artemis III mission and provided insights into the mission’s objectives and challenges. The crew will undertake a series of critical tests in Earth orbit, essential for the subsequent Artemis IV mission, which aims to land the first crewed mission at the lunar South Pole in 2028.
The Artemis III Crew and Mission Objectives
The Artemis III crew consists of NASA astronauts Randy Bresnik (commander), Andre Douglas (mission specialist), and Frank Rubio (mission specialist), along with ESA astronaut Luca Parmitano (pilot). NASA astronaut Bob Hines has been named as the backup crew member. This diverse team will be responsible for conducting a series of challenging tests in Earth orbit, including rendezvous and docking capabilities with test versions of the commercial human landing systems developed by Blue Origin and SpaceX.
The mission will involve a multi-launch campaign of the world’s most powerful rockets, testing integrated hardware between the Orion spacecraft and the landers. This includes system interfaces, software, propulsion, and communications. The crew will also demonstrate the capability to dock with both the Blue Origin lander and the SpaceX Starship lander, a critical step toward achieving the mission’s goals.
The Space Launch System and Orion Preparations
NASA’s Space Launch System (SLS) rocket and the Orion spacecraft are central to the Artemis III mission. Following the successful Artemis II launch in April 2026, the mobile launcher is in excellent condition, with modifications between Artemis I and II proving highly successful. The boosters have arrived at the rotation processing surge facility and are being prepared for stacking. The mobile launcher, which sustained some damage during the launch, is undergoing repairs, with 90% of the work already completed.
One of the key components for the Artemis III mission is the second stage simulator, known as the spacer. This component is crucial for the mission, as it replaces the Interim Cryogenic Propulsion Stage (ICPS) upper stage. The spacer design is already complete, and metal is being bump-formed at United Launch Alliance. It is expected to arrive at Kennedy Space Center no later than December, allowing for the stacking of the Orion spacecraft on top of it.
The Lunar Landers: Blue Origin and SpaceX
The Artemis III mission will feature two lunar landers: one developed by Blue Origin and the other by SpaceX. The Blue Origin lander, referred to as a lander test articleis an intermediate version between the Mk 1 and Mk 2. It includes the same lunar crew module, avionics, and flight software as the final lander but uses storable propellants and a reaction control system instead of the BE-7 engines. This test article will allow NASA to conduct component testing and evaluate the environmental control and life support system (ECLSS).
The Blue Origin lander for Artemis III can be launched on the existing 7×2 variant of the New Glenn rocket. Despite a recent pad explosion, Blue Origin remains confident in meeting the mission’s timeline. The company is working on two launch pads capable of handling the larger 9×4 version of the New Glenn rocket. NASA is closely monitoring the situation and has considered alternative launch vehicles, such as Vulcan or Falcon Heavy, if necessary.
The SpaceX Starship will also play a crucial role in the Artemis III mission. Unlike the Blue Moon lander, the Starship will not carry astronauts inside it. Instead, it will focus on integrated stack control and avionics flight software integration. These tests are essential for reducing the risk associated with the lunar landing mission. The Starship’s large size and the smaller Orion spacecraft present unique challenges that need to be addressed before the mission.
NASA’s Artemis III mission represents a significant step forward in lunar exploration. With the crew, landers, and mission objectives in place, the space agency is poised to achieve another historic milestone in its journey back to the Moon.
