Comet Hopper (CHopper) was a proposed lander to NASA's Discovery Program that, had it been selected, would have orbited and landed multiple times on Comet Wirtanen as it approaches the Sun. The proposed mission is led by Jessica Sunshine of the UMD, working with Lockheed Martin to build the spacecraft and the NASA Goddard Spaceflight Center to manage the mission.〔(【引用サイトリンク】publisher=NASA )〕 ==History== The Comet Hopper mission was one of three Discovery Program finalists that received USD$3 million in May 2011 to develop a detailed concept study. The other two missions were InSight and Titan Mare Explorer. After a review in August 2012, NASA selected the InSight mission.〔(NASA will send robot drill to Mars in 2016 ), Washington Post, By Brian Vastag, Monday, August 20〕
