All clear ☀️ In this image, the Tropospheric Doppler Radar Wind Profiler is shown during an #Artemis I weather simulation on Nov. 3, 2021. This instrument is located on five acres near the Launch and Landing Facility at Kennedy Space Center in Florida. The wind profiler will serve as the primary upper level wind instrument for NASA’s Artemis missions. The 640 antennae deliver data from 6,000 to 62,000 feet high (2,000 to 19,000 meters high) every five minutes. The instrument works by shooting radar beams into the sky, where it detects particles of dust, clouds, and moisture within turbulent eddies. The instrument’s radar aligns with the rocket’s flight path, providing more rapid and reliable wind measurements than traditional weather balloons. Teams will use real-time weather data from the wind profiler and weather balloons to design vehicle steering commands, upload the commands onto vehicle flight computers, and verify that vehicle constraints remain within acceptable limits durin...
