In the News Artemis II, the first crewed mission to the moon since Apollo 17, was launched on 1 April. During the lunar flyby, it became the furthest spaceflight in human history on the 6th. Integrity, the re-entry vehicle, splashed down southwest of San Diego on the 11th. On 8 April, the first satellites of the Celeste (LEO-PNT) constellation began broadcasting navigation signals for the first time.
Featured Content The image "STS-133 Space Shuttle Discovery after undocking" was promoted to Featured Media status on 30 April. It was nominated by Moonreach.
Article of the month Gallaudet Eleven The Gallaudet Eleven were a group of eleven deaf men recruited in the late 1950s and 1960s to participate in a joint research program led by NASA and the U.S. Naval School of Aviation Medicine (later changed to Aerospace Medical Association) to study the effects of prolonged weightlessness on the human body. They were selected for participation in the study because damage they had sustained to the vestibular systems of their inner ears had granted them immunity to motion sickness, making them uniquely resilient to certain physical studies that would have made other test subjects nauseous.	Image of the month Clayton Anderson under weightlessness A demonstration of weightlessness by astronaut Clayton Anderson, particularly its effect on liquids. The water's surface tension keeps it in a sphere, which here results in the light reflecting off of Anderson being refracted in such a way that it appears upside-down. It is only upside-down relative to Anderson, as there is no "up" or "down" in a weightless environment beyond convention.
