After returning to Earth, Artemis II commander Reid Wiseman said the journey was not without tense moments. Artemis II was designed as a full-scale test of the systems required for deep-space exploration. Reid Wiseman was selected as a NASA astronaut in 2009 and served as commander of the Artemis II mission. The Artemis II crew spoke with President Donald J. Trump following their historic lunar flyby. Artemis II also demonstrated that modern lunar missions rely on much broader international cooperation than the Apollo program did.
