A #CosmicVision mission, #ESACheops was launched in 2019. Cheops is the first space mission dedicated to studying bright, nearby stars that are already known to host #exoplanets. It's also the first in a trio of ESA missions dedicated to exploring exoplanets. 1/ 🔭 #CM25

SWOOSH! 🧹 When a meteoroid struck Mars, it triggered ~100 dust avalanches down an ancient volcano's slopes. @esa.int's ExoMars Trace Gas Orbiter captured the dramatic effect of the rare cascade. A new @nature.com study examines the most common causes of these streaks. www.esa.int/ESA_Multimed...
