Earth Images from ESA Astronaut Alexander Gerst

This timelapse video was made from images taken by ESA astronaut Alexander Gerst orbiting Earth on the International Space Station. The video is offered in Ultra High Definition, the highest available to consumers. Be sure to change the settings in YouTube if your computer or television can handle it for the full effect. The montage is made from a long sequence of still photographs taken at a resolution of 4256 x 2832 pixels at a rate of one every second. The high resolution allowed the ESA production team to create a 3840 x 2160 pixel movie, also known as Ultra HD or 4K. Playing these sequences at 25 frames per second, the film runs 25 times faster than it looks for the astronauts in space. The artistic effects of the light trails from stars and cities at night are created by superimposing the individual images and fading them out slowly. Alexander Gerst is a member of the International Space Station Expedition 40 crew. He is spending five and a half months living and working on the ISS for his Blue Dot mission.

Radar satellite missions can measure millimetre-scale changes in Earth’s surface following an earthquake. On 24 August 2014, an earthquake struck California’s Napa Valley. By processing two images from the Sentinel-1A radar satellite, which were acquired on 7 August and 31 August 2014 over this wine-producing region, an 'interferogram' was generated showing ground deformation.

Ball Aerospace has been involved with the commercial and government sides of Earth-observation satellites for some time, including instrument and satellite construction for DigitalGlobe as well as the primary imager for the Landsat 8 satellite. Earth Imaging Journal spoke with Cory Springer, director of weather and environment at Ball Aerospace, about the prospects for environmental monitoring, the need to continue the data record for the Landsat program, the CAVIS instrument on DigitalGlobe’s WorldView-3 satellite that removes the impact of weather on the image, and the motivating role of the International Space Symposium.
