What color is Pluto? The answer, revealed in the first maps made from New Horizons data, turns out to be shades of reddish brown. Although this is reminiscent of Mars, the cause is almost certainly very different. On Mars the coloring agent is iron oxide, commonly known as rust. On the dwarf planet Pluto, the reddish color is likely caused by hydrocarbon molecules that are formed when cosmic rays and solar ultraviolet light interact with methane in Pluto’s atmosphere and on its surface.
BALTIMORE, Md. (JHU APL PR) — After 18 months in orbit — months longer than typical for spacecraft in their class — the twin ORS Tech 1 and 2 CubeSats recently completed their final trip into Earth’s atmosphere.
The agency is working on two concepts for the mission. The first concept would fully capture a very small asteroid in free space and the other would retrieve a boulder off of a much larger asteroid. Both concepts would redirect an asteroid mass less than 10 meters in size to orbit the moon. Astronauts aboard the Orion spacecraft launched on the Space Launch System (SLS) would rendezvous with the captured asteroid mass in lunar orbit and collect samples for return to Earth.
