NASA would get $5 billion for its Science Mission Directorate under a bill approved today by the Senate Appropriations Subcommittee on Commerce, Justice, Science and Related Agencies. That is slightly above the president's $4.92 billion request and $69 million less than the level appropriated in fiscal year 2012. The markup restores $100 million of a proposed $227 million cut the Administration had proposed to make to the account for Mars robotic exploration.
It's not clear yet if this restored funding—if the bill should become law—will in fact restore components of the 2016 and 2018 Mars missions that NASA had originally intended to undertake in collaboration with the European Space Agency. More details to come on ScienceInsider.
