Polar Auroras In High-Definition ISS Time Lapse Video By German Astronaut

 

 

 

 

 

 

” A German astronaut has captured stunning images of polar auroras as he orbited Earth on the International Space Station. Alexander Gerst’s images led to the creation of the Ultra-HD – or ‘4K’ time lapse video, running at 25 frames per second.

  The photographs were taken at a resolution of 4,256 x 2,832 pixels and depict Gerst’s orbit around the Earth alongside his fellow ISS Space Station expedition 40 crewmembers.

  His journey shows the rippling greenish lights characteristic of the electrically-charged sun particle collisions, bright city lights in the nighttime, the different hues of the Earth’s atmosphere and a satellite launch. “

 

 

The description from ESA’s Youtube page provides more detail on the creation of the Ultra High Def video :

 

” 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. “

Air Force’s Mysterious X-37B Space Plane Nears One Year In Orbit

 

 

 

 

” The unmanned X-37B spacecraft — flying a mission known as Orbital Test Vehicle 3 (OTV-3) — launched into space atop an Atlas 5 rocket from Florida’s Cape Canaveral Air Force Station on Dec. 11, 2012. What payloads the space plane is toting and the overall mission goals on its confidential cruise are classified.

  But it is known that the OTV-3 mission signals a milestone for the X-37B program. “
