NASA’s Artemis II Crew Training Ramps Up for Lunar Flyby

The countdown to humanity’s return to the Moon is ticking, and the preparation has moved from theoretical classrooms to the open ocean. NASA’s Artemis II crew is currently deep in the execution phase of their training, focusing heavily on water recovery and critical capsule operations to ensure they are ready for their scheduled September 2025 launch.

From Classroom to the Pacific Ocean

For the four astronauts selected for this historic mission, the training wheels are off. Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialists Christina Koch and Jeremy Hansen have spent recent months conducting rigorous recovery drills. This phase is vital because Artemis II marks the first time humans will ride the Orion capsule.

The crew recently completed a major milestone known as Underway Recovery Test 11 (URT-11). This exercise took place in the Pacific Ocean off the coast of San Diego. Unlike previous tests that used test dummies or empty capsules, this drill involved the actual flight crew working alongside the U.S. Navy.

During these operations, the astronauts practiced the intricate process of exiting the Orion capsule after splashdown. The capsule bobs in the ocean waves, which can be a nauseating experience after days in zero gravity. The team worked directly with Navy divers and crew members aboard the USS San Diego (LPD-22). They rehearsed the “open water” extraction where they exit the side hatch, inflate a “front porch” raft, and are hoisted by helicopter or brought onto the recovery ship.

Why Water Recovery is Critical

Splashdown is one of the most dangerous phases of spaceflight. Once the heat shield survives the fiery reentry through Earth’s atmosphere, the physical safety of the crew depends on a swift retrieval. The training ensures that:

  • Medical evaluations start immediately: Flight surgeons need to access the crew within minutes of recovery.
  • Capsule integrity is maintained: The team practices securing the capsule so it does not take on water or sink before recovery.
  • Coordination is seamless: The communication loop between the astronauts, the recovery divers, and Mission Control in Houston must be perfect.

Inside the Orion Simulator

While the ocean drills handle the end of the mission, much of the crew’s time is spent at the Johnson Space Center in Houston, Texas. Here, they utilize high-fidelity simulators to practice every second of the 10-day mission profile.

The training team creates specific scenarios to test the crew’s reaction times. These are not just routine flight checks. The simulation supervisors, often called “Sim Sups,” inject complex failures into the system. The crew must respond to:

  • Communication blackouts: Losing contact with the Deep Space Network.
  • Life support failures: Managing drops in cabin pressure or issues with the carbon dioxide scrubbers.
  • trajectory errors: Making manual adjustments if the automated guidance computers fail during the Trans-Lunar Injection (TLI) burn.

Because Artemis II is a “free-return trajectory” mission, the crew will fly around the Moon and let gravity sling them back to Earth. They will not enter a low lunar orbit or attempt a landing. This profile allows them to focus entirely on testing the life support systems of the Orion spacecraft, which were not fully active during the uncrewed Artemis I flight.

Emergency Egress at Kennedy Space Center

Training also takes place on the ground at the launch site. The crew has conducted emergency egress drills at Launch Pad 39B at the Kennedy Space Center in Florida.

If a dangerous anomaly occurs with the Space Launch System (SLS) rocket before liftoff, the crew needs a way to escape the top of the tower rapidly. NASA has installed a new emergency egress system involving slide-wire baskets that resemble high-speed ski gondolas.

During these drills, the astronauts practice:

  1. Unstrapping from their seats in the Orion capsule.
  2. Opening the hatch manually.
  3. Sprinting across the crew access arm (the bridge connecting the rocket to the tower).
  4. Loading into the escape baskets which slide down cables to a safe bunker area on the ground.

The Crew Configuration

The dynamic of this specific crew is a major part of the training. Each member brings a specific background that influences how they handle operations:

  • Reid Wiseman (Commander): A naval aviator and test pilot who previously served as Chief of the Astronaut Office. He is responsible for overall mission success and safety.
  • Victor Glover (Pilot): An experienced F/A-18 pilot who flew the first operational SpaceX Crew Dragon mission. He will monitor systems and execute manual control if necessary.
  • Christina Koch (Mission Specialist): She holds the record for the longest single spaceflight by a woman (328 days). Her focus is on the science payloads and stowage operations.
  • Jeremy Hansen (Mission Specialist): Representing the Canadian Space Agency (CSA), Hansen is the first non-American to leave low-Earth orbit. He manages timeline execution and assists with navigation checks.

Looking Toward September 2025

NASA initially targeted late 2024 for this mission, but the date was pushed to September 2025 to allow more time for safety checks on the Orion heat shield and electrical systems. The crew is using this extra time to refine their coordination.

The current training block is designed to build “muscle memory.” When the crew is 230,000 miles from Earth, they cannot rely solely on instructions from the ground due to light-speed communication delays. They must know the Orion capsule inside and out. The combination of water recovery practice, simulator stress tests, and launch pad drills ensures that when the SLS rocket finally ignites, the human element of the system is as ready as the hardware.

Frequently Asked Questions

When will Artemis II launch? NASA is currently targeting September 2025 for the launch of Artemis II. This date allows engineers to resolve issues found with the heat shield and life support circuitry during the Artemis I analysis.

Will the Artemis II crew land on the Moon? No. Artemis II is a lunar flyby mission. The crew will travel around the Moon to test the spacecraft’s systems and return to Earth. The actual lunar landing is scheduled for the Artemis III mission.

Where does the water recovery training take place? The open water recovery training occurs in the Pacific Ocean, typically off the coast of San Diego, California. They also train in the Neutral Buoyancy Laboratory (a giant pool) at the Johnson Space Center.

What ship is used to recover the capsule? NASA partners with the US Navy for recovery operations. Recent tests used the USS San Diego (LPD-22), an amphibious transport dock ship capable of bringing the Orion capsule into its well deck.
