In its fiscal 2015 budget, NASA has included a small deposit on a possible mission to one of the solar system's potentially most habitable spots: Jupiter's ice-sheathed moon Europa. <\/p>\n
The agency is asking Congress for $15 million to officially begin identifying affordable concepts for a Europa mission, noted Elizabeth Robinson, NASA's chief financial officer, at a briefing on Tuesday. <\/p>\n
At the moment, the agency has no official cost estimate for such a mission and a launch date no more specific than sometime in the mid-2020s. But a 2012 study commissioned by NASA highlighted three approaches that carried price tags ranging from $1.8 billion to $3 billion. Of those, the study team identified a $2.1 billion mission as the one that would return the most science for the best price. It consisted of a spacecraft performing multiple flybys of Europa. <\/p>\n
While $15 million may seem like chump change against a potential price tag of $2 billion, give or take, putting the figure in the budget \"is significant, it means we're getting serious,\" says James Green, who heads NASA's planetary science division. <\/p>\n
Congress has already delivered $80 million to NASA to begin spadework on a mission to Europa in mind. Now, by putting the mission in the budget, the Office of Management and Budget (OMB) is giving the program a new level of concreteness, since it must include spending estimates for an additional four years beyond fiscal 2015. <\/p>\n
\"The fact that OMB put it in as line item by name says that administration finally got the message that Congress was going to insist on this and they might as well go ahead and put it in the budget,\" says Scott Hubbard, former head of NASA's Mars exploration program and now a consulting professor of aeronautics and astronautics at Stanford University in Palo Alto, Calif. <\/p>\n
