Artemis II Crew Answers Questions Mid-Flight on Journey to Moon

Four astronauts hurtling toward the Moon in a spacecraft named Integrity fielded questions from reporters Thursday as NASA's Artemis II mission entered its third day of flight, offering a rare live window into what the agency is genuinely testing on humanity's first crewed lunar journey in more than 50 years.

Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialist Christina Koch, all with NASA, along with Canadian Space Agency Mission Specialist Jeremy Hansen, participated in the first downlink event of their mission, answering questions as Orion pressed on toward the Moon.

The milestone that put the crew on its lunar trajectory came Thursday evening, when Orion's main engine fired for five minutes and 50 seconds beginning at 7:49 p.m. EDT to complete the translunar injection burn, sending the spacecraft out of Earth orbit. Orion's engine produces up to 6,000 pounds of thrust, enough to accelerate a car from zero to 60 mph in about 2.7 seconds. At the time of the burn, Orion's mass was 58,000 pounds, and the spacecraft burned approximately 1,000 pounds of fuel during the firing.

The Q&A separated mission color from mission stakes. Hansen, the only crew member making his spaceflight debut and the first Canadian ever to venture toward the Moon, described his first days in weightlessness with unguarded enthusiasm: "I just kept saying to them yesterday, like I really like it up here. I wish I could have got here sooner. It's just such a tremendous place to be." But behind the awe, the crew was also working through early technical surprises. Koch said the eight-minute ascent was surprisingly smooth, described as a steady rumble and a great ride, though Glover noted the temperature inside Orion ran cold enough that he wished the crew had brought different sleeping bags. Mission control was working with the crew to warm the cabin.

Earlier in the mission, the crew called down to report a blinking fault light during a checkout of the spacecraft's toilet. A communication problem between Eastern Range and the flight termination system had also surfaced before launch, as did a temperature spike in one of the two batteries in the Launch Abort System, which engineers determined was an instrumentation sensor failure rather than an actual battery issue.

Each of those "hiccups," as NASA engineers framed them, carries direct implications for Artemis III, the mission that would put boots on the lunar surface. This flight is the first crewed test of Orion's life support systems, and it will push the spacecraft through reentry velocities that represent genuinely new territory. NASA Administrator Jared Isaacman underscored the point: "The velocities that that spacecraft is going to reenter at — it's gonna be new territory for us. We want to get our arms around that completely."

The Orion heat shield, which suffered unexpected damage on the uncrewed Artemis I flight in 2022, remains under scrutiny. NASA decided to proceed with Artemis II using the existing shield after a design review, with modifications to address AVCOAT permeability issues planned for the Artemis III heat shield.

Flight Day 3 added further technical work to the agenda, including the first outbound trajectory correction burn, for which Hansen was tasked with preparation, as well as CPR procedures in weightlessness, a medical kit checkout, and an emergency communications system test using the Deep Space Network.

The mission is expected to surpass the record for the farthest distance humans have ever traveled from Earth, set by the Apollo 13 crew at 248,655 miles, before the crew loops around the Moon and begins its return to Earth for splashdown. How cleanly Orion performs that reentry will determine how quickly NASA can clear Artemis III for its lunar surface attempt.
