How NASA’s Spitzer has stayed alive for so long
After nearly 16 years of exploring the cosmos in infrared light, NASA’s Spitzer Space Telescope will be switched off permanently on Jan. 30, 2020. By then, the spacecraft will have operated for more than 11 years beyond its prime mission, thanks to the Spitzer engineering team’s ability to address unique challenges as the telescope slips farther and farther from Earth.
