Exploration Missions
Main article: Exploration of MarsIn addition to observation from Earth, some of the latest Mars information comes from five active probes on or in orbit around Mars including three orbiters and two rovers. This includes 2001 Mars Odyssey, Mars Express, Mars Reconnaissance Orbiter, Opportunity rover, and Curiosity rover.
Dozens of unmanned spacecraft, including orbiters, landers, and rovers, have been sent to Mars by the Soviet Union, the United States, Europe, and Japan to study the planet's surface, climate, and geology. The public can request images of Mars via the HiWish program.
The Mars Science Laboratory, named Curiosity, launched on November 26, 2011, reached Mars on August 6, 2012 UTC. It is larger and more advanced than the Mars Exploration Rovers, with a movement rate up to 90 m (300 ft) per hour. Experiments include a laser chemical sampler that can deduce the make-up of rocks at a distance of 7 m (23 ft).

Famous quotes containing the words exploration and/or missions:
“For women who do not love us, as for the “disappeared”, knowing that we no longer have any hope does not prevent us form continuing to wait. We live on our guard, on watch; women whose son has gone asea on a dangerous exploration imagine at any minute, although it has long been certain that he has perished, that he will enter, miraculously saved, and healthy.”
—Marcel Proust (1871–1922)
“There was only one catch and that was Catch-22, which specified that a concern for one’s own safety in the face of dangers that were real and immediate was the process of a rational mind.... Orr would be crazy to fly more missions and sane if he didn’t, but if he was sane he had to fly them. If he flew them he was crazy and didn’t have to; but if he didn’t want to he was sane and had to.”
—Joseph Heller (b. 1923)
