The Artemis II astronauts are chatting it up with their friends aboard the International Space Station. Still aglow from their triumphant lunar flyby, the three Americans and one Canadian put in a call to their station colleagues Tuesday while heading home from the moon. It's the first such moonship-to-spaceship radio linkup ever. "We have been waiting for this like you can't imagine," the commander Reid Wiseman said. NASA's Apollo moonshots had no off-the-planet company back in the 1960s and 1970s. For Artemis II's Christina Koch and the station's Jessica Meir, it was a joyous space reunion despite being 230,000 miles apart. The two teamed up for the world's first all-female spacewalk in 2019.

The replacements for the astronauts involved in NASA's first medical evacuation are on their way to the International Space Station. SpaceX launched the fresh crew on Friday from Florida. The four astronauts are representing the U.S., France and Russia and should reach the orbiting lab Saturday. They'll fill the vacancies left by their evacuated colleagues. NASA had to put spacewalks on hold and defer other duties after an unidentified astronaut experienced a serious medical issue in January. The entire crew returned to Earth more than a month early, leaving three astronauts in orbit.
