The quest to explore Jupiter's ocean-harboring moon Europa has taken a big step forward. <\/p>\n
The White House's fiscal year 2016 budget request for NASA, which was released Monday (Feb. 2), allocates $18.5 billion to the space agency, including $30 million to formulate a mission to Europa, perhaps the solar system's best bet to host alien life. NASA has been studying a potential Europa mission for a while now, but the new budget proposal signals a commitment from the White House that wasn't there before. <\/p>\n
\"For the first time, the budget supports the formulation and development of a Europa Mission, allowing NASA to begin project formulation, Phase A,\"NASA officials wrotein a summary of the proposed budget. [Photos: Europa, Mysterious Icy Moon of Jupiter] <\/p>\n
Indeed, the new budget request assumes multiple years of funding for a Europa mission, said NASA Chief Financial Officer David Radzanowski. <\/p>\n
\"The current funding profile would assume a launch in the mid-2020s,\" Radzanowskitold reporters during a conference call Monday. <\/p>\n
It's unclear at the moment just how much NASA and the Europa project will actually get in the 2016 fiscal year (FY), which begins Oct. 1, 2015. Congress must approve the final budget, which often looks quite different than the one proposed by the White House. <\/p>\n
For example, the Obama administration allocated $15 million for early work on a potential Europa mission in its FY 2015 budget request, but Congress later upped that to $100 million. <\/p>\n
NASA appears to be zeroing in on a mission that would feature multiple flybys of Europa perhaps something along the lines of theEuropa Clipper, a concept being developed by agency scientists and engineers.Once in orbit around Jupiter, the Clipper would make 45 flybys of the 1,900-mile-wide (3,100 kilometers) Europa over the course of 3.5 years, as the concept is currently envisioned. <\/p>\n
Europa is thought to possess an ocean of liquid water under its icy shell. During its many flybys, the Clipper would confirm and study that ocean, yielding insights about its depth, salinity and conductivity, among other characteristics. <\/p>\n
The Clipper would also measure and map Europa's ice shell, returning data that could be useful for a potential future mission to the moon's surface. <\/p>\n
