Yuri’s Night is the largest annual and global celebration of space exploration encompassed by humanity’s past, present, and future in space through scientific and technical achievements. Yuri’s Night parties and events are held around the world in hundreds of cities every April in commemoration of April 12, 1961, the day of Russian Cosmonaut Yuri Gagarin’s first manned spaceflight.
The Mineral Moon (NASA/JPL) - this mosaic of 53 images was recorded by the Jupiter-bound Galileo spacecraft as it passed near our own large natural satellite in 1992.
