Human Activities in Space
NASA’s future exploration plans include outposts on the Moon, though many of the details and specifications for these habitats are yet to be determined. According to NASA: “Astronauts will set up a lunar outpost — possibly near a south pole site called Shackleton Crater — where they’ll conduct scientific research, as well as test technologies and techniques for possible exploration of Mars and other destinations.”
Surface systems are those systems that operate on the surface of a planet. Current operational surface systems include the NASA Jet Propulsion Laboratory (JPL) Mars Rovers, Spirit and Opportunity. These robots were launched in June and July 2003, with the purpose of understanding the history of water on Mars.
