Mars Exploration Rover NASA's twin rovers, named Spirit and Opportunity, launched separately in 2003 and landed three weeks apart in January 2004. They made important discoveries about wet environments on ancient Mars that may have been favorable for supporting microbial life. Although Spirit ceased communicating with Earth in March 2010, Opportunity continues its work on the Red Planet.
Was launched into low Earth orbit April 24th, 1990. Operating outside the distortion of the Earth’s atmosphere it is able to take extremely high-resolution visible-light images. Hubble has recorded some of the most detailed visible-light images ever, allowing a deep view into space and time.
InSight, short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is a robotic lander designed to study the deep interior of the planet Mars. InSight launched on May 5, 2018 and successfully landed on Mars on Nov. 26, 2018.
Its finding are expected to shed light on the processes responsible for the formation of Mars, Earth, and even rocky exoplanets more than 4 billion years ago.
