Jeff Foust, DENVER – NASA has selected missions to return samples from a comet and to explore Titan with a drone as finalists for the next New Frontiers medium-class planetary science mission. The two missions, selected from a pool of 12 proposals and announced by NASA Dec. 20, will receive funding for additional studies through 2018 before NASA picks one of them in the spring of 2019 for full development and launch in 2025. One, called Comet Astrobiology Exploration SAmple Return, or CAESAR, would visit the comet 67P/Churyumov-Gerasimenko and collect a sample from its nucleus for return to Earth, the first such sample return mission. The mission would be managed by NASA's Goddard Space Flight Center using a spacecraft built by Orbital ATK. The other, Dragonfly, would send a spacecraft to land on Titan, Saturn's largest moon and a world with a dense atmosphere. That spacecraft, similar to a quadcopter drone, would be able to fly to several locations on the surface, tens to hundreds of kilometers apart, to study its composition and habitability. The mission would be managed by the Applied Physics Laboratory (APL) of Johns Hopkins University, which would also build the spacecraft. |
