NASA Dawn Asteroid Mission Told To ‘Stand Down’ .
The decision to stand down, according to SPACE.com sources, appears related to budget-related measures and workforce cutbacks at the Jet Propulsion Laboratory (JPL) in Pasadena, California. http://www.space.com/missionlaunches/051107_dawn_qown.html Rakhir |

That possibility has been considered for Dawn in the past, and rejected as not cost-effective -- it cuts the total cost of the mission only slightly. (Also, of the two asteroids, Vesta is consisently ranked higher priority scientifically, being more unique.)

(Also, of the two asteroids, Vesta is consisently ranked higher priority scientifically, being more unique.) How do you get to be "more unique" than something else? Okay, forget the sucky semantics of the phrasing -- the implication is that Ceres is in a class with some other object or objects which we've already studied, so we can expect to learn less that is new at Ceres than at Vesta. But what other objects is Ceres in a class with? I wasn't under the impression that it was particularly like anything else. |
