NASA is targeting 7:50 a.m. EDT Thursday, July 30, for the launch of its Mars 2020 Perseverance rover on a United Launch Alliance Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida. The launch window is approximately two hours, with a launch opportunity every five minutes.
Live launch coverage will begin at 7 a.m., on NASA Television and the agency’s website.
The mission – designed to better understand the geology and climate of Mars and seek signs of ancient life on the Red Planet – will use the robotic scientist, which weighs just under 2,300 pounds (1,043 kilograms) and is the size of a small car, to collect and store a set of rock and soil samples that could be returned to Earth by future Mars sample return missions. It also will test new technologies to benefit future robotic and human exploration of Mars.
NASA’s Jet Propulsion Laboratory, managed by Caltech in Southern California, built the Perseverance rover and will manage mission operations for NASA. The agency’s Launch Services Program, based at NASA’s Kennedy Space Center in Florida, is responsible for launch management.
Mars 2020 Perseverance is part of America’s larger Moon to Mars exploration approach that includes missions to the Moon as a way to prepare for human exploration of the Red Planet. Charged with sending the first woman and next man to the Moon by 2024, NASA will establish a sustained human presence on and around the Moon by 2028 through NASA’s Artemis program.
Due to the coronavirus (COVID-19) pandemic, media participation in news conferences will be remote. Only a limited number of media, who already have been accredited, will be accommodated at Kennedy. For the protection of media and Kennedy employees, the Kennedy Press Site News Center facilities will remain closed to all media throughout these events.
Questions may be asked via social media with the hashtag #CountdownToMars.
