Artemis II Astronauts Chat With ISS From Moon's Edge
8 Apr
Summary
- Artemis II crew communicated with the ISS during their journey home.
- Astronauts discussed Earth's beauty and the vastness of space.
- New laser communication system transmitted data 20 gigabytes in under an hour.

The Artemis II mission has concluded its journey around the moon and is now heading back to Earth. The spacecraft Integrity, carrying four astronauts, departed lunar influence on Tuesday afternoon, accelerating towards a splashdown in the Pacific Ocean on Friday. During their return, the crew engaged in a 12-minute conversation with colleagues aboard the International Space Station (ISS).
Astronauts on the ISS inquired about the crew's perspective of Earth from lunar proximity. Christina Koch described observing Earth's beauty against the immense blackness of space. The conversation, hampered by a 2.5-second communication delay, also touched upon the limited space within the Orion capsule compared to the ISS.
Further observations from the mission include potential meteor impacts on the moon's dark side, described as momentary flashes without noticeable color. Data transmitted via a new laser communication system proved highly efficient, sending 20 gigabytes in just over 45 minutes. Scientists are now actively analyzing the vast amount of new information and imagery collected during the mission.
