Artemis II’s Christina Koch speaks with “astro sister” Jessica Meir in rare ship-to-ship call

During a 15-minute ship-to-ship, audio-only call on April 7, 2026, the Artemis II crew spoke with NASA astronauts Jessica Meir, Jack Hathaway, and Chris Williams, and ESA (European Space Agency) astronaut Sophie Adenot aboard the International Space Station. Jessica Meir and Christina Koch both served together as NASA astronauts aboard ISS during Expedition 61 in 2019–2020. During that mission, they made history by conducting the first all‑female spacewalks alongside each other.
