Embry-Riddle Aeronautical University SmallSat Launched with NOAA-20
EagleSat-1 is a scientific investigation from Embry-Riddle Aeronautical University in Prescott, Arizona, that flew on the JPSS-1 (now NOAA-20) mission. It attempted to measure the decay of the satellite’s orbit over time by the means of an unlocked Global Positioning System (GPS) receiver in the space environment. The primary experiment concerned the use of supercapacitors for the battery bank. The satellite is composed of structures, power, communications, GPS experiment, and onboard computer (OBC) subsystems. The radio transmitter within the satellite was donated by Wood & Douglas, part of the Ultra Electronics group in the United Kingdom.
Northrop Grumman Space Systems
Contractor for the JPSS-2, -3 and -4 spacecraft. Northrop Grumman is responsible for the design, production and integration of JPSS spacecraft, full satellite environmental testing, and support to launch/early orbit checkout.
VIIRS Sees Museum Fire Near Flagstaff in Summer 2019
In July 2019, NOAA-20 imaged the Museum Fire, just 2 miles north of Flagstaff, AZ. By the time it was 100 percent contained in mid-August, the fire had burned 1,961 miles in the Dry Lake Hills area. These images were captured in the very early morning using the VIIRS instrument’s Day/Night Band sensor, which can see in very low light conditions, like moonlight or atmospheric airglow. Fire events pose dangers to life as well as the potential for property loss. VIIRS data and products can improve emergency personnel’s situational awareness of wildfire events.
