Alexander Gerst was once a geophysicist in Germany before the European Space Agency offered him to become an astronaut in 2009. His previous experience was very useful for the Internal Space Station’s mission “Blue Dot”. It’s about a six-month research program, in cooperation with ESA, designed to “improve life on Earth, or prepare for a further study of the solar system.”
During the mission, which lasted from May to November, Gerst was involved in experiments in physics, biology, human physiology and radiation. He was responsible for docking the spacecraft and unloading goods.
Gerst also had a hobby on the side. He often set up his camera in automatic mode, which constantly filmed the Earth below. Now ESA has used 12,500 of these images to create an ultra-HD video timelapse.
In just six minutes the clip covers most of our planet’s beautiful wonders, including the northern lights, sunrises, clouds, stars, oceans, the Milky Way, the International Space Station, lightning, cities at night, spacecraft, and the thin strip of atmosphere that protects us from space.
