Moon tree Moon tree Moon trees are trees grown from 500 seeds taken into orbit around the Moon by Stuart Roosa during the Apollo 14 mission in 1971. As the Command Module Pilot on the Apollo 14 mission, and as he had been a smoke jumper, Roosa was contacted by Ed Cliff, who was the Chief of the Forest Service at the time, and who proposed the idea of taking the seeds along. Seeds for the experiment were chosen from five different types of trees: loblolly pine, sycamore, sweetgum, redwood, and Douglas fir. The seeds orbited the moon, but were not landed
Huygens (spacecraft) Huygens (spacecraft) Huygens was an atmospheric entry probe that landed successfully on Saturn's moon Titan in 2005. Built and operated by the European Space Agency (ESA), it was part of the "Cassini–Huygens" mission and became the first spacecraft ever to land on Titan and the farthest landing from Earth a spacecraft has ever made. The probe was named after the Dutch 17th-century astronomer Christiaan Huygens, who discovered Titan in 1655. The combined "Cassini–Huygens" spacecraft was launched from Earth on October 15, 1997. "Huygens" separated from the "Cassini" orbiter on December 25, 2004, and landed on Titan on January 14, 2005
