The Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight)[1] mission was a robotic lander designed to study the deep interior of the planet Mars.[1][11][12] It was manufactured by Lockheed Martin Space, was managed by NASA's Jet Propulsion Laboratory (JPL),[13] and two of its three scientific instruments were built by European agencies.[14] The mission launched on 5 May 2018 at 11:05:01 UTC aboard an Atlas V-401 launch vehicle[15] and successfully landed[16] at Elysium Planitia on Mars on 26 November 2018 at 19:52:59 UTC.[17][18][15][19] InSight was active on Mars for 1440 sols (1480 days; 4 years, 19 days).

InSight's objectives were to place a seismometer, called Seismic Experiment for Interior Structure (SEIS), on the surface of Mars to measure seismic activity and provide accurate 3D models of the planet's interior; and measure internal heat transfer using a heat probe called HP3 to study Mars' early geological evolution.[20] This was intended to provide a new understanding of how the Solar System's terrestrial planetsMercury, Venus, Earth, Mars – and Earth's Moon formed and evolved.

The lander was originally planned for launch in March 2016.[12][21] An instrument problem delayed the launch beyond the 2016 launch window. NASA officials rescheduled the InSight launch to May 2018[22] and during the wait the instrument was repaired. This increased the total cost from US$675 million to US$830 million.[23][24]

InSight successfully landed on Mars on 26 November 2018. Due to excessive dust on its solar panels preventing it from recharging, NASA put InSight in low-power mode for detecting seismic events in July 2022 and continued monitoring the lander through the operational period ending in December 2022.[25][26] On 20 December 2022, NASA announced that the InSight lander had lost communications with Earth on 15 December 2022, with the end of the mission being declared on 21 December 2022.[5][6][27]
