NASA personnel breathed a collective sigh of relief on Wednesday following the flawless launch of the highly anticipated Artemis II mission. With the safety of four astronauts, the agency's prestige, and America's standing in the modern space race all on the line, the stakes could not be higher.
Now, the focus shifts from clearing the launchpad to surviving the cosmos. Here is an inside look at the crew's critical first day in space.
Orbiting Earth and Pushing Limits
Currently stationed approximately 42,500 miles above Earth, astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen are actively putting the Orion spacecraft through its paces. Shortly after escaping the atmosphere, the minibus-sized capsule successfully deployed its solar arrays, securing the necessary power for the historic voyage ahead.
Because Orion has never carried human passengers into space before, pilot Victor Glover is dedicating the mission's early stages to rigorously testing its capabilities. NASA engineers need absolute certainty that the vessel is fully functional before the crew commits to deep space, a realm where emergency returns are nearly impossible. In a worst-case scenario, however, the astronauts are equipped with advanced survival suits capable of keeping them alive for roughly six days.
Squats, Snacks, and Space Pajamas
Unlike the Apollo era, the Artemis II journey is heavily documented, with NASA livestreaming the crew's activities. Audiences have tuned in to watch the astronauts check monitors, press control panels, and float through the cabin.
Roughly eight hours post-launch, the strict daily schedule dictated by Mission Control permitted the crew to rest. Commander Reid Wiseman famously radioed in to request the team's "comfort garments"—space pajamas—before they grabbed their first four-hour nap. Adapting to weightlessness can make sleeping difficult, requiring the astronauts to strap themselves securely to the walls.
Physical health is equally managed down to the minute. To combat the loss of bone density and muscle mass caused by zero gravity, the crew must exercise for half an hour daily. Wiseman and Glover were the first to test out Orion's compact "flywheel" device, while Koch and Hansen were slated to use it later for squats, deadlifts, and rowing exercises.
Dining in space has also seen some modern upgrades, though refrigeration remains absent. The crew pre-selected their freeze-dried menus, hydrating meals like beef brisket and macaroni and cheese using onboard water dispensers, all washed down with their daily ration of coffee or chocolate breakfast drinks—and flavored with five different hot sauces.
A Bathroom Crisis Averted
Perhaps the most relatable triumph of the mission thus far involves the spacecraft's plumbing. During the launch phase, the onboard toilet malfunctioned, sparking fears that the crew would endure a grueling 10-day flight without proper facilities. Thankfully, under guidance from Mission Control, Christina Koch successfully repaired the specialized commode. Ground teams humorously radioed their confirmation that the toilet was operational, advising the crew to let the system reach full operating speed before "donating fluid."
The Final Push to the Moon
With basic survival and comfort secured, the crew is now preparing for the critical "trans-lunar injection" burn. Scheduled for Thursday evening (UK time), this massive engine firing is designed to violently push the capsule out of Earth's orbit and hurl it toward the Moon.
Any delay or cancellation of this burn would represent a massive blow to the United States' goal of returning humans to the lunar surface by 2028. However, if the six-minute propulsion goes exactly as planned, Artemis II will embark on a trajectory that uses the Moon's gravity to catapult the spacecraft back home.
By Monday, April 6, the crew is expected to fly roughly 6,400 miles beyond the lunar far side. While uncrewed probes from nations like China and India have explored this perpetually shadowed region, the Artemis II astronauts will be the first humans to lay eyes on it directly, capturing vital observations and photographs for the world to see.
