The Artemis II astronauts who ignited a lunar renaissance are giving high marks to their moonship for its performance during reentry — especially the heat shield. They held their first news conference Thursday since returning to Earth. Speaking from Houston, the three Americans and one Canadian said their lunar flyby puts NASA in a better position to land a crew on the moon in just two years and set up an eventual moon base. The first lunar crew in more than a half-century launched April 1 and became the most distant travelers ever from Earth as they whipped around the moon's far side.

Once there, the spacecraft will orbit the giant gas planet, sneaking close to Europa during dozens of flybys.
