5,400-Pound NASA Satellite Falls Back to Earth After 38 Years in Space – By Amanda Kooser (CNET) / Jan 9, 2023
NASA expected some satellite components to survive the reentry.
Here’s one for the “what goes up must come down” file. NASA’s Earth Radiation Budget Satellite got a blazing welcome back to Earth on Sunday after nearly four decades in space. On Monday, NASA said the Department of Defense confirmed the 5,400-pound (2,450-kilogram) satellite had reentered over the Bering Sea.
ERBS made contributions to climate and weather science. Atmospheric reentry as a retirement present was a long time coming for the old satellite, which originally launched from the Space Shuttle Challenger in late 1984.
The satellite had an expected two-year-service life, but it blew past that mark. “For 21 of its years in orbit, the ERBS actively investigated how the Earth absorbed and radiated energy from the Sun, and made measurements of stratospheric ozone, water vapor, nitrogen dioxide, and aerosols,” NASA said.
