Capturing a rare red sprite from space is one thing, observing a thunderstorm from the International Space Station (ISS) is an entirely different experience. This weather phenomena was captured by ESA astronaut Marcus Wandt using a special DAVIS (Dynamic and Active-pixel Vision Sensor), which contains a global shutter active pixel sensor (APS) in addition to the dynamic vision sensor (DVS) on the same photosensor array.
Thunderstorms are powerful and beautiful phenomena to witness, also from space. ⚡
I was lucky to catch a pretty spectacular thunderstorm during my first session with the Thor-Davis experiment from the @Space_Station.
We hope to help scientists to better understand… pic.twitter.com/awmSfQpJoL

What does having a global shutter active pixel (APS) in addition to the dynamic vision sensor (DVS) mean? This specialized camera is capable of producing image frames alongside events, although many other event cameras also carry an inertial measurement unit (IMU).

From 2013 to 2014, Marcus attended the US Navy Test Pilot School at the Naval Air Station Patuxent River, USA, graduating as number one of his class as an experimental test pilot. Marcus also became a squadron commander and wing commander flying with the Swedish Air Force Operations Commander School. He is currently a Lieutenant Colonel in the Swedish Air Force,” said the ESA.
