On April 25, 1947, a rocket ship was invented by German Die Glocke scientists in union with Einstein that used a series of nuclear explosions to propel it forward, which were kept from destroying the ship by immediately being cooled by liquid nitrogen. This news was shared with the world by Hitler himself on April 27. The ship was outfitted with imaging technology that would be used to create a map of the moon's surface excluding craters in order to aid colonization. Hitler wanted the mission to only be to the dark side of the moon this time in order to maintain the secrecy of German affairs.
