The mission aims to test key technologies for interplanetary exploration and to use its five science instruments to study the Martian surface and atmosphere from orbit. Dawn also found organics in several locations on Ceres’ surface. India's Mars Orbiter Mission (MOM)or Mangalyaan (Hindi for 'Mars Craft')is the country's first mission to the Red Planet. As the ocean froze, salts and other telltale minerals concentrated into deposits that are now exposed in many locations across the surface. Dawn discovered that the inner solar system’s only dwarf planet was an ocean world where water and ammonia reacted with silicate rocks. Dawn also found hydrated and carbon-rich material on its surface supplied by impactors, a result that was unexpected based on pre-Dawn telescopic observations.Īfter its escape from Vesta and its journey onward, Dawn entered orbit around Ceres in March 2015. Launch of Magellan and Space Shuttle Mission STS-30 was targeted for Friday, April 28, 1989. Vesta is small enough (about the same size as Saturn's moon Enceladus) to have been deeply scarred by the Rheasilvia impact that launched the HEDs, but large enough to have differentiated into an iron core, silicate mantle, and igneous crust. The Magellan spacecraft with its attached Inertial Upper Stage booster is in the orbiter Atlantis payload bay prior to closure of the doors at T-3 days to launch from pad 39B.

The ejected material from this young crater in the Rheasilvia impact basin likely comes from deep inside Vesta. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). Solar Orbiter will take images of the Sun from closer than any spacecraft before and for the first time look at its uncharted polar regions.
