Chief engineer, NASA’s Space Technology Mission Directorate, Jeff Sheehy, gives remarks via remote during a NASA Perseverance rover mission engineering and technology overview, Tuesday, Feb. 16, 2021, at NASA's Jet Propulsion Laboratory in Pasadena, California. The Perseverance Mars rover is due to land on Mars Thursday, Feb. 18, 2021. A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith.

Jeff Sheehy, Space Technology Mission Directorate, NASA Headquarters, participates in a Mars 2020 Mission Tech and Humans to Mars Briefing at NASA’s Kennedy Space Center in Florida on July 28, 2020. The Mars Perseverance rover is scheduled to launch July 30, on a United Launch Alliance Atlas V 541 rocket from Space Launch Complex 41 at nearby Cape Canaveral Air Force Station. The rover is part of NASA’s Mars Exploration Program, a long-term effort of robotic exploration of the Red Planet. The rover will search for habitable conditions in the ancient past and signs of past microbial life on Mars. The Launch Services Program at Kennedy is responsible for launch management.

CAPE CANAVERAL, Fla. – Members of NASA’s International Space Station science team brief news media representatives in the Kennedy Space Center’s Press Site auditorium in preparation for the launch of the SpaceX CRS-4 mission to resupply the International Space Station. Jeff Sheehy, senior technologist for the Space Technology Mission Directorate, participated in the briefing. The mission is the fourth of 12 SpaceX flights NASA contracted with the company to resupply the space station. It will be the fifth trip by a Dragon spacecraft to the orbiting laboratory. The spacecraft’s 2.5 tons of supplies, science experiments, and technology demonstrations include critical materials to support 255 science and research investigations that will occur during the station's Expeditions 41 and 42. Liftoff is targeted for an instantaneous window at 2:14 a.m. EDT.
