Justin Hall assembles parts of a cradle for a rotorcraft that will air launch a proposed atmospheric probe in summer 2024 at NASA’s Armstrong Flight Research Center in Edwards, California. Hall is a designer, technician, and pilot at the center’s Dale Reed Subscale Flight Research Laboratory.

The atmospheric probe model on a stand is prepped for flight and release from a quad rotor remotely piloted aircraft. The probe successfully flew on Oct. 22, 2024, above Rogers Dry Lake, a flight area adjacent to NASA’s Armstrong Flight Research Center in Edwards, California. The probe was designed and built at the center. In the background from left are Justin Hall, chief pilot of small, unmanned aircraft systems; Justin Link, small unmanned aircraft systems pilot; communications writer Jay Levine; and John Bodylski, atmospheric probe principal investigator.

Antenna's on NASA's Parker Solar Probe are deployed for testing at the Astrotech processing facility in Titusville, Florida, near NASA's Kennedy Space Center on Thursday, April 19, 2018. The Parker Solar Probe will launch on a United Launch Alliance Delta IV Heavy rocket from Space Launch Complex 37 at Cape Canaveral Air Force Station in Florida no earlier than Aug. 4, 2018. 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 our understanding of the corona and the Sun-Earth connection.

On Friday, Aug. 10, 2018, at Cape Canaveral Air Force Station in Florida, the United Launch Alliance Delta IV Heavy rocket stands ready to boost NASA's Parker Solar Probe on a mission to study the Sun following rollback of the Mobile Service Tower gantry at Space Launch Complex 37.

Parker Solar Probe is humanity’s first-ever mission into a part of the Sun’s atmosphere called the corona. Here it will directly explore solar processes that are key to understanding and forecasting space weather events that can impact life on Earth. Photo Credit: (NASA/Bill Ingalls)
