InSight is a robotic lander designed to study the interior of the planet Mars. The mission launched on 5 May 2018 at 11:05 UTC and is expected to land on the surface of Mars at Elysium Planitia on 26 November 2018, where it will deploy a seismometer and burrow a heat probe. It will also perform a radio science experiment to study the internal structure of Mars. (via Wikipedia)

Hayabusa2 is an asteroid sample-return mission operated by the Japanese space agency, JAXA. It follows on from Hayabusa and addresses weak points identified in that mission. Hayabusa2 was launched on 3 December 2014 and rendezvoused at near-Earth asteroid 162173 Ryugu on 27 June 2018. It is intended to survey the asteroid for a year and a half, depart in December 2019, and return to Earth in December 2020.

Hayabusa2 carries multiple payloads for science: remote sensing, sampling, and lander/rovers—four small probes that will investigate the asteroid surface. (via Wikipedia)
