NASA's Robotic Missions
NASA selected three finalists to be the agency’s next cheap, robotic exploration mission. Depending on which wins, a probe will head for Venus, the moon, or a near-Earth object no later than 2018.

Name: The Surface and Atmosphere Geochemical Explorer (SAGE)
Destination: Venus
Principal Investigator: Larry Esposito of the University of Colorado in Boulder
Plan: The SAGE mission would release a probe that would descend through Venus’ thick atmosphere to its surface. There, it would dig into the crust and measure its composition, not unlike what the Phoenix Lander did on Mars.
Why: “Venus is like a twin sister of the Earth, and it’s gone terribly bad,” Esposito told Colorado Daily. Scientists want to know what happened.
Name: Origins Spectral Interpretation Resource Identification Security Regolith Explorer (Osiris-Rex)
Destination: A “primitive asteroid”
Principal Investigator: Michael Drake, of the University of Arizona in Tucson
Plan: Osiris-Rex would fly to a primitive asteroid, orbit it, and then land on it. After collecting two ounces of material, it would fly the samples back to Earth. It’s a bit like Russia’s planned Phobos-Grunt mission, which would return samples from a Martian moon. (Osiris is pictured above.)
Why: “A primary motivation for an asteroid sample return mission is the desire to both acquire samples with known geologic context and to return materials that are either unlikely to survive passage to Earth (e.g., friable, volatile-rich material) or would be compromised by terrestrial contamination upon their fall (e.g.,
extraterrestrial organics).” — according to a description of the mission plan [pdf]
Name: MoonRise
Destination: Aitken Basin, at the Moon’s south pole
Principal Investigator: Bradley Jolliff, of Washington University in St. Louis
Plan: The mission would place a lander in a south polar lunar basin, where it would excavate about two pounds of lunar material. The samples would be returned to Earth.
Why: The area where MoonRise would dig is believed to be composed of rocks from the moon’s mantle conveniently exposed by a massive meteorite strike. Understanding the interior of the moon could help explain a lot about the formation of the solar system.
Final Decision will be up in 2011
Till then let us see what the CEans like if they have to choose
Which out of three will you select guys? and Why?
