NASA's Cute Companion to Accompany James Webb on Space Mission.

NASA has selected a cubesat called MANTIS to accompany the James Webb Space Telescope on its mission to study exoplanets. MANTIS will observe stars in the full range of ultraviolet light, including extreme UV light, which will help the cubesat study stars that burn dozens of light-years away from Earth. MANTIS will fill in the blanks for the much larger telescope, providing important context on the stellar environments in which these planets live. The mission is scheduled to launch in 2026.
