The Tropospheric Doppler Radar Wind Profiler, located on five acres near the Launch and Landing Facility at Kennedy Space Center in Florida, is shown during an Artemis I weather simulation on Nov. 3, 2021. The simulation involved teams from Kennedy, Cape Canaveral Space Force Station, Johnson Space Center in Texas, and Marshall Space Flight Center in Alabama. The radar wind profiler consists of 640 antennae and delivers data – from 6,000 to 62,000 feet – every five minutes. The instrument will be used as the primary upper level wind instrument for NASA’s Artemis missions, including Artemis I, the first launch of the agency’s Space Launch System rocket and the Orion spacecraft on a flight beyond the Moon.
