“We are proud to launch the Mars 2020 mission to orbit,” said Gary Wentz, ULA vice president of Government and Commercial Programs. “The discoveries from the Mars 2020 mission will provide crucial science and research that will help inform NASA’s future plans to put humans on the Moon and Mars. We look forward to continuing the Mars mission legacy with our NASA partners.”
One of the most powerful rockets in the Atlas V fleet, the 541 configuration, with four solid rocket boosters, provides optimum performance to precisely deliver a range of mission types. In addition to three national security and two weather satellites, an Atlas V 541 rocket launched NASA’s Curiosity rover on its 10-month, 354 million-mile journey to the surface of Mars.
This Atlas V 541 configuration vehicle includes a 5-meter payload fairing (PLF) and stands 197 ft. tall. The Atlas booster for this mission is powered by the RD AMROSS RD-180 engine. Aerojet Rocketdyne provided the four AJ-60A SRBs and RL10C-1 engine for the Centaur upper stage.
NASA’s Launch Services Program (LSP) at the agency’s Kennedy Space Center in Florida selected United Launch Alliance’s (ULA’s) proven Atlas V vehicle for this mission and is responsible for management and oversight of the Atlas V launch services. LSP selected this rocket because it has the right liftoff capability for the “heavy weight” requirements for NASA’s Mars 2020 Perseverance rover launch.
To date ULA has launched 139 times with 100 percent mission success.
With more than a century of combined heritage, ULA is the world’s most experienced and reliable launch service provider. ULA has successfully launched more than 135 missions to orbit that provide Earth observation capabilities, enable global communications, unlock the mysteries of our solar system, and support life-saving technology.
