According to internal documents about the 2015 budget request, NASA will ask for funding for “pre-formulation” studies of a Europa mission as well as a Wide Field Infrared Survey Telescope/Astrophysics Focused Telescope Asset mission. The ISS would also be given funding for its extension, and the Commercial Crew Program would receive funds at a level permitting certification by 2017. Other funds are being requested for advanced solar electric propulsion and non-toxic ‘green’ spacecraft propellant. (Image Credit: NASA-JPL)
