"We have come up with what Paul Hertz asked us to do, which is to come up with a probe mission at the cost cap of $1 billion," said Karl Stapelfeldt of NASA Goddard in a presentation about Exo-C at the ExoPAG meeting.
An independent cost estimate of an earlier iteration of the mission concept, performed by the Aerospace Corporation in September, came out to be $1.1 billion, he said. An updated design, submitted to Aerospace for costing in December, should be less, he said.
Exo-C would make use of the Kepler spacecraft bus, equipped with a 1.4-meter telescope and a coronagraph to allow direct imaging of exoplanets. The use of the Kepler-heritage technology, plus a launch on a SpaceX Falcon 9 rocket, allows the mission to fit into the $1 billion cost cap, he said. "Even if we don't get to fly this mission, we've done the community a service by showing that there does exist at least one probe mission concept in this $1 billion cost cap level," Stapelfeldt said.
