  • US space agency, NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander successfully touched down on the Red Planet on November 26, 2018 after an almost seven-month, 300-million-mile (458-million-kilometer) journey from Earth. 
  • InSight’s two-year mission will be to study the deep interior of Mars to learn how all celestial bodies with rocky surfaces, including Earth and the Moon, formed. 
  • InSight was launched from Vandenberg Air Force Base in California May 5,2018. The lander touched down  near Mars’ equator on the western side of a flat, smooth expanse of lava called Elysium Planitia, with a signal affirming a completed landing sequence at 11:52 a.m. PST (2:52 p.m. EST). 
  • The landing signal was relayed to NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, via NASA’s two small experimental Mars Cube One (MarCO) CubeSats, which launched on the same rocket as InSight and followed the lander to Mars.
  • They are the first CubeSats sent into deep space. After successfully carrying out a number of communications and in-flight navigation experiments, the twin MarCOs were set in position to receive transmissions during InSight’s entry, descent and landing.
