The James Webb Space Telescope (JWST) is one of NASA’s latest telescopes that hopes to better understand the universe. But how does the JWST stay on? The JSWT utilizes solar panels to power its internal systems. Satellites were one of the first uses for Solar Panels, and the Vanguard 1 satellite was one of the first to be powered by solar energy. The JWST consists of (5) solar panels that make up a 2kW system, but its still enough to power the onboard systems. The use of solar panels has allowed us to look further into the universe and learn more about ourselves. See the articles below for more information about the solar panels on the JWST, or to see breathtaking photos captured by the telescope.
