Latest Dawn Stories
NASA said on Wednesday its Dawn spacecraft has revealed new details about the surface of the asteroid Vesta.
Since last July, NASA's Dawn spacecraft has been orbiting the asteroid Vesta, and capturing images and other data that are providing surprising results to the delight and amazement of researchers.
Why does NASA sometimes schedule a rocket launch for the middle of the night, or aim for a liftoff time when weather is notoriously unlikely to cooperate?
Though generally thought to be quite dry, roughly half of the giant asteroid Vesta is expected to be so cold and to receive so little sunlight that water ice could have survived there for billions of years.
No one expected a 13-mile high mountain, two and a half times higher than Mount Everest.
NASA's Dawn spacecraft has sent back the first images of the giant asteroid Vesta from its low-altitude mapping orbit. The images, obtained by the framing camera, show the stippled and lumpy surface in detail never seen before.
In 2011, NASA began developing a heavy-lift rocket for the human exploration of deep space, helped foster a new era of commercial spaceflight and technology breakthroughs, fully utilized a newly complete space station, and made major discoveries about the universe we live in, many of which will benefit life on Earth.
NASA's Dawn spacecraft successfully maneuvered into its closest orbit around the giant asteroid Vesta on Monday, Dec. 12, beginning a new phase of science observations.
NEAR-Shoemaker Mission -- The Near Earth Asteroid Rendezvous - Shoemaker (NEAR Shoemaker), renamed after its launch in honor of Gene Shoemaker, is an unmanned spacecraft designed to study the near-Earth asteroid Eros from close orbit over a period of a year. The primary scientific objectives of NEAR were to return data on the bulk properties, composition, mineralogy, morphology, internal mass distribution and magnetic field of Eros. Secondary objectives include studies of regolith...
