ExoMars 2028 is a second mission of two-part European Space Agency astrobiology project to search for evidence of life on Mars. The primary objective is to land the rover at a site with high potential for finding well-preserved organic material, particularly from the very early history of the planet. The rover is expected to travel several kilometers during its mission. The European rover will be the first mission to combine the capability to move across the surface and to study Mars at depth. It will collect samples with a drill down to a depth of 2 m and analyze them with next-generation instruments in an onboard laboratory. Underground samples are more likely to include biomarkers, since the tenuous martian atmosphere offers little protection from radiation and photochemistry at the surface.

The Falcon Heavy is a variant of the Falcon 9 full thrust launch vehicle and consists of a standard Falcon 9 rocket core, with two additional boosters derived from the Falcon 9 first stage.

Space Exploration Technologies Corp., known as SpaceX, is an American aerospace manufacturer and space transport services company headquartered in Hawthorne, California. It was founded in 2002 by entrepreneur Elon Musk with the goal of reducing space transportation costs and enabling the colonization of Mars. SpaceX operates from many pads, on the East Coast of the US they operate from SLC-40 at Cape Canaveral Space Force Station and historic LC-39A at Kennedy Space Center. They also operate from SLC-4E at Vandenberg Space Force Base, California, usually for polar launches. Another launch site is being developed at Boca Chica, Texas.
