NASA's reach spans the universe. The rover Opportunity is still studying Mars after arriving with its twin Spirit in 2004. Cassini orbits around Saturn, as Juno makes its way to Jupiter. The Hubble Space Telescope continues to explore the deepest reaches of the cosmos. The crew of the International Space Station is extending the permanent human presence in space. Earth Science satellites are sending unprecedented data on Earth's oceans, climate and other features. NASA's aeronautics team is working with other government organizations, universities, and industry to fundamentally improve the air transportation experience and retain our nation's leadership in global aviation.
