[b]Long Distance Call, First Return Correction Burn[/b] Four International Space Station (ISS) Expedition 74 astronauts had a ship-to-ship call with the four Artemis II astronauts on Tuesday (April 7) after the latter flew around the moon. The station crewmates called Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen, who are returning to Earth aboard the spacecraft Integrity, for a short conversation. The station crew expressed their curiosity about the difference between the two spacecraft, while the Artemis II crewmates shared their experience seeing the moon up close. Koch, who performed a pair of station spacewalks with Jessica Meir in January 2020 and who is now back on the station now, remarked, "Every single thing that we learned on ISS is up here." At 8:03 p.m. EDT, Integrity ignited its thrusters for 15 seconds, producing a change in velocity of 1.6 feet-per-second and guiding the Artemis II crew toward Earth. NASA astronaut Christina Koch and CSA (Canadian Space Agency) astronaut Jeremy Hansen reviewed procedures and monitored the spacecraft's configuration and navigation data. Wiseman, Glover, Koch and Hansen also tested an orthostatic intolerance garment — specialized equipment designed to help astronauts maintain blood pressure and circulation during the transition back to Earth's gravity. The crew also took manual control of Integrity, using the spacecraft's field of view to center a designated target before guiding Orion to a tail to Sun attitude and comparing its control modes. The manual piloting demonstration began at 10:00 p.m. EDT.
