Titan Mare Explorer (TiME) is a proposed design for a lander for Saturn's moon Titan.〔 TiME is a relatively low-cost, outer-planet mission designed to measure the organic constituents on Titan and would have performed the first nautical exploration of an extraterrestrial sea, analyze its nature and, possibly, observe its shoreline. As a Discovery-class mission it was designed to be cost-capped at US$425 million, not counting launch vehicle funding.〔 It was proposed to NASA in 2009 by Proxemy Research as a scout-like pioneering mission, originally as part of NASA's Discovery Program. The TiME mission design reached the finalist stage during that Discovery mission selection, but was not selected. Although TiME got another possibility in late 2013 to obtain funding, NASA has since cancelled the development of the power source that would be required, advanced Stirling radioisotope generators. == Discovery-class finalist == TiME was one of three Discovery Mission finalists that received US$3 million in May 2011 to develop a detailed concept study. The other two missions were InSight and Comet Hopper. After a review in Summer 2012, NASA announced in August 2012 the selection of the InSight mission to Mars. Missions to land in Titan's lakes or seas were also considered by the Solar System Decadal Survey. Additionally, the flagship Titan Saturn System Mission, which was proposed in 2009 for launch in the 2020s, included a short-lived battery-powered lake lander.〔
