From left, Lori Glaze, Tom Statler, Andy Rivkin, Betsy Congdon, and Simone Pirrotte participate in an engineering briefing for the agency’s Double Asteroid Redirection Test (DART) mission at Vandenberg Space Force Base in California on Nov. 21, 2021. DART is the first mission to test technologies for preventing an impact of Earth by a hazardous asteroid. The mission is scheduled to launch no earlier than 1:21 a.m. EST Wednesday, Nov. 24 (10:21 p.m. PST Tuesday, Nov. 23), aboard a SpaceX Falcon 9 rocket from Vandenberg. NASA's Launch Services Program based at Kennedy Space Center in Florida, America's multi-user spaceport, is managing the launch.

In the Kennedy Space Center’s Press Site auditorium, on Friday, July 20, 2018, Betsy Congdon, Thermal Protection System engineer with the Johns Hopkins University Applied Physics Laboratory, right, demonstrates the ability of the Parker Solar Probe's heat shield to protect the spacecraft. The presentation for the media took place during a prelaunch mission briefing for the Parker Solar Probe mission. The Parker Solar Probe will lift off on a United Launch Alliance Delta IV Heavy rocket from Space Launch Complex 37 at Cape Canaveral Air Force Station in Florida. The spacecraft was built by Applied Physics Laboratory of Johns Hopkins University in Laurel in Maryland. The mission will perform the closest-ever observations of a star when it travels through the Sun's atmosphere, called the corona. The probe will rely on measurements and imaging to revolutionize understanding of the corona and the Sun-Earth connection.
