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.

50 years ago, NASA launched Nimbus to study Earth from space. Now, experts at the National Snow and Ice Data Center (part of CIRES), are recovering valuable data and images from old, long-lost film, and expanding their understanding of sea ice in the Arctic and Antarctic. Learn more from CIRES on the 1-year anniversary of Nimbus' first image:

Australia has a combined land and sea territory of more than 8 million square kilometers. Yet most of this is currently out of the reach of affordable communication. Now the University of South Australia's Institute for Telecommunications Research has turned this on its head, with the development of the Global Sensor Network. The Global Sensor Network is an innovative signal processing system which provides low cost, two-way, simultaeneous satellite communications to multiple users.

Re/code visits NASA's Silicon Valley research center, where a pair of startups are working together to democratize satellite data. Aquila Space is building a fleet of satellites while its partner Astro Digital is developing software tools that allow anyone to process and analyze the data. Among other things, the information could be used to help inform policy and responses for ecological disasters, including the droughts and wildfires plaguing California.
NASA’s Earth Minute: Mission to Earth?
0 Views0 Comments0 Likes
NASA doesn't just explore outer space! Since 1959, with the launch of the first weather satellite, NASA has been studying our home planet on a global scale. NASA monitors Earth's vital signs via satellites and airplanes, sends scientists to the far corners of the land and under the ocean, and develops computer models of Earth's climate processes. Why? Because Earth is the only planet that nearly eight billion people call "home sweet home."
TOPEX/JASON Sees 22-Year Sea Level Rise

This visualization shows total sea level change between 1992 and 2014, based on data collected from the TOPEX/Poseidon, Jason-1, and Jason-2 satellites. Blue regions are where sea level has gone down, and orange/red regions are where sea level has gone up. Since 1992, seas around the world have risen an average of nearly 3 inches. The color range for this visualization is -7 cm to +7 cm (-2.76 inches to +2.76 inches), though measured data extends above and below 7cm(2.76 inches). This particular range was chosen to highlight variations in sea level change. Download the visualization: http://svs.gsfc.nasa.gov/cgi-bin/deta....
