__ Hubble __ __ Explorer 1 __
 * Hubble is a giant telescope that orbits around the Solar System and takes pictures of planets, stars, asteroids, and other objects in space.
 * The main reason they sent Hubble out was to act as a celestial observatory.
 * Launched in April 1990
 * They were able to observe other planets and celestial objects
 * They’ve had to send up multiple maintenance crews every couple of years
 * They’re sending the last maintenance crew out on August 28, 2008
 * Sent out to measure cosmic rays in Earth’s orbit
 * January 31st, 1958 is when it was launched
 * Dr. James Van Allen discovered with Explorer 1 that there’s a much lower cosmic ray count than was expected
 * It burned up while entering the Earth’s atmosphere
 * 3 more versions of Explorer were launched after Explorer 1

__ XMM-Newton __
 * Sent out to answer mysteries such as enigmatic black holes and the formation of galaxies
 * Launched December 10th, 1999
 * There have been no problems with Newton
 * Because of Newton’s highly eccentric orbit, scientists are going to be able to see deep into space
