NASA Now Streaming Live HD Camera Views of Earth from Space (Video)

Editor's note:  The live video stream above is from NASA's International Space Station feed on Ustream. It is accompanied by audio conversations between the space station's astronaut crew and Mission Control during worktimes, and video is only available when the station is in contact with Mission Control. If you see a blue screen, the station has experienced a temporary loss of signal with the ground.

The video above is NOT from NASA's High Definition Earth Viewing (HDEV) experiment, which is no longer active. The HDEV live video experiment ran from 2014 to October 2019 and is no longer in service. Our original story on the HDEV experiment is below.


Daydreaming about being an astronaut just got a whole lot easier.

NASA is now live-streaming views of Earth from space captured by four commercial high-definition video cameras that were installed on the exterior of the International Space Station last month. The project, known as the High Definition Earth Viewing (HDEV) experiment, aims to test how cameras perform in the space environment. You can see the live HD views of Earth from space above.

"The cameras are enclosed in a temperature-specific housing and are exposed to the harsh radiation of space," NASA officials write in an online description of the HDEV experiment. "Analysis of the effect of space on the video quality, over the time HDEV is operational, may help engineers decide which cameras are the best types to use on future missions.

Some of the cameras' components were designed by high school students as part of the High Schools United with NASA to Create Hardware, according to a NASA description of the experiment. The students are also operating the experiment.

You can follow NASA's stream directly here: http://www.ustream.tv/channel/iss-hdev-payload. If the screen is black, don't worry — the space station is likely just on Earth's night side. (The station completes one orbit every 90 minutes, so you won't have to wait too long for our gorgeous planet to roll into view once again.) 

The webcast of HD Earth video feed is also on Space.com, and will be accompanied by other live space broadcasts as events warrant.

The HDEV gear arrived at the orbiting lab aboard SpaceX's robotic Dragon capsule, which blasted off on its third contracted cargo mission on April 18. (SpaceX holds a $1.6 billion deal with NASA to make 12 such resupply flights.) Astronauts then installed the cameras on the space station, and they became operational on April 30.

HDEV isn't the only Earth-imaging project aboard on the International Space Station.

The Vancouver-based company UrtheCast (pronounced "Earthcast") has two HD cameras on the orbiting lab. One of them, known as Theia, takes pictures with a resolution of 16.5 feet (5 meters), while the other camera records video that can resolve details as small as 3 feet (1 m) across.

These two cameras, which together cost $17 million, were installed by spacewalking cosmonauts in January. UrtheCast released the first images from Theia last month and plans to begin streaming near-realtime views of Earth from orbit soon, bringing lots of viewers to their website.

UrtheCast also aims to sell its imagery to a variety of customers, including government agencies interested in tracking resource use and private companies that want to keep tabs on their operations (and perhaps the operations of their competitors).

This story was updated on May 8 to include details on the student participation in the HD Earth Viewing experiment.
