Media Affairs Specialist, JPL, DC Agle, moderates a NASA Perseverance rover mission engineering and technology overview, Tuesday, Feb. 16, 2021, at NASA's Jet Propulsion Laboratory in Pasadena, California. The Perseverance Mars rover is due to land on Mars Thursday, Feb. 18, 2021. A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith.

DC Agle, with NASA’s Jet Propulsion Laboratory, moderates a Mars 2020 Mission Engineering and Science Briefing at NASA’s Kennedy Space Center in Florida on July 27, 2020. The Mars Perseverance rover is scheduled to launch July 30, on a United Launch Alliance Atlas V 541 rocket from Space Launch Complex 41 at nearby Cape Canaveral Air Force Station. The rover is part of NASA’s Mars Exploration Program, a long-term effort of robotic exploration of the Red Planet. The rover will search for habitable conditions in the ancient past and signs of past microbial life on Mars. The Launch Services Program at Kennedy is responsible for launch management.

CAPE CANAVERAL, Fla. – – A Gravity Recovery and Interior Laboratory (GRAIL) mission science briefing is held in the NASA Press Site auditorium at NASA's Kennedy Space Center in Florida. From left are DC Agle, NASA Public Affairs; Robert Fogel, NASA’s GRAIL program scientist; Maria Zuber, GRAIL principal investigator with the Massachusetts Institute of Technology; Sami Asmar, GRAIL deputy project scientist, NASA’s Jet Propulsion Laboratory; and Leesa Hubbard, teacher in residence, Sally Ride Science, San Diego. GRAIL is scheduled to launch Sept. 8 aboard a United Launch Alliance Delta II Heavy rocket from Cape Canaveral Air Force Station in Florida. GRAIL will fly twin spacecraft in tandem around the moon to precisely measure and map variations in the moon's gravitational field. The mission will provide the most accurate global gravity field to date for any planet, including Earth. This detailed information will reveal differences in the density of the moon's crust and mantle and will help answer fundamental questions about the moon's internal structure, thermal evolution, and history of collisions with asteroids. The aim is to map the moon's gravity field so completely that future moon vehicles can safely navigate anywhere on the moon’s surface. For more information, visit http://www.nasa.gov/grail.
