Artemis II Crew to Conduct Moon Observations, Equipment Tests on Day 3

NASA’s Artemis II astronauts began their journey toward the moon after a trans-lunar injection burn. The burn occurred on April 2 and pushed Orion beyond high Earth orbit.

Engine burn and service module

The Orion spacecraft’s main engine fired from the European Service Module on April 2. That module supplies power, thrust, and life support to the crew.

Trajectory adjustments and mission timeline

Teams followed the main burn with smaller outbound trajectory correction firings. The first of three smaller engine burns ensured Orion stayed on course.

April 3 marks the mission’s third day. The crew moved from basic operations to planned investigations.

Day 3 activities

Mission schedules released under the heading Artemis II Crew to Conduct Moon Observations, Equipment Tests on Day 3 outline planned tasks. Astronauts will run equipment checks and begin science rehearsals.

They will also practice procedures intended for the close lunar flyby on day six. These rehearsals focus on observation and data collection techniques.

Lunar observation preparations

Crew members will rehearse how to observe and document lunar surface features. Human vision can reveal details and colors cameras may miss.

Some views will be unique compared with Apollo-era observations. Apollo missions mostly saw the near side when it was fully sunlit.

Exercise and health routines

Athletes in microgravity lose muscle quickly. The crew will use a flywheel exercise device for resistance and aerobic workouts.

These sessions help preserve strength in Orion’s confined living space.

Medical and safety drills

Astronauts will perform medical demonstrations like CPR. They will inspect items in the onboard medical kit.

• Thermometer
• Blood pressure monitor
• Stethoscope
• Otoscope

Specific tasks are assigned to crew members. Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialist Jeremy Hansen will lead medical checks.

Mission Specialist Christina Koch will test Orion’s emergency communications with the Deep Space Network. The DSN uses large antennas in California, Spain, and Australia.

Upcoming milestones

Artemis II will arrive near the moon on the mission’s fifth day. The crew will not land.

On day six, they will swing around the far side for their closest lunar pass. They will be the first humans to travel that far since Apollo 17 in 1972.
