NASA astronaut Jonny Kim has posted his first time-lapse video of Earth from the International Space Station (ISS), showcasing stunning auroras, lightning storms and city lights illuminating the night-side of our planet’s surface.
The former U.S. Marine launched to the ISS on April 8 earlier this year aboard a Russian-built Soyuz spacecraft, beginning an eight month tour of duty as flight engineer for Expedition 73. Prior to capturing his first time-lapse footage of Earth, Kim sought advice from fellow crewmember Nichole “Viper” Ayers, who regularly posts stunning astrophotography on her social accounts that showcases the natural splendor of our ‘Blue Marble’.
“Thanks to some instruction and tips from @Astro_Ayers, I caught my first aurora,” wrote Kim in a Twitter/X post accompanying the time-lapse video. “After seeing the result, I told her this felt like fishing. Prepping the camera, the angle, the settings, the mount, then setting your timer and coming back to hope you got a catch. And after catching my first fish, I think I’m hooked. Thanks, Vapor!”
Kim’s time-lapse captures a dizzying blend of natural phenomena and city lights on Earth’s surface, as the space station’s solar panels shifted position to gather the precious sunlight used to power the orbital outpost.
The footage begins with the sun setting behind Earth’s disk, heralding the onset of night aboard the ISS – the 45 minute period when the station passes through our planet’s shadow. Stars can be seen shining above the outline of our planet’s dense, gaseous atmosphere as the sun sets, while city lights and lightning storms play across the cloudy vista below.
Vivid green auroras are captured rippling across the night sky towards the end of the video, as the station passed over southeastern Asia and Australia. These colorful displays arise when energetic particles carried by the solar wind collide with our planet, exciting oxygen and nitrogen particles in the upper atmosphere, causing them to shine, according to NASA’s Jet Propulsion Laboratory.
Kim’s time-lapse ends as the station passes back into the day-side of our planet, with its solar panels basking in direct sunlight. The ISS completes 16 laps of our planet every 24 hours while travelling at an average speed of 17,500 mph ( 28,000 km/h).
