  • Life science was the main science topic aboard the International Space Station on Wednesday. The Expedition 65 crew is also packing a U.S. Cargo ship and maintaining orbital lab systems today. Four astronauts, who rode to the station aboard the SpaceX Crew Dragon Endeavour, kicked off the day with the first health checkup of their expedition today.
  • The Expedition One crew spent a relatively quiet day today aboard the International Space Station (ISS) as they prepare for the arrival of an unmanned resupply craft late next week. The crew will be given three days off Saturday, Sunday and Monday to relax following a busy period of activity since launch on October 31.

  • This is a chronological list of expeditions to the International Space Station (ISS). All permanent ISS crews are named 'Expedition n ', where n is sequentially increased with each expedition. Resupply mission crews and space tourists are excluded (see List of human spaceflights to the ISS for details).

Observing of the International Space Station

The International Space Station (ISS) can easily be spotted with the naked eye. Because of its size (110m x 100m x 30m), it reflects a large amount of sunlight.

When will nasa retire iss today

The best time to observe the ISS is when it is nighttime at your location, and the Space Station is sunlit. Often, such a viewing situation occurs in the morning before sunrise, or in the evening after sunset.

Formerly the site for the High Definition Earth-Viewing System (HDEV) : Operational: April 30, 2014 – End of Life: August 22, 2019.
See more information below.

Currently, live video of Earth is streaming from an external HD camera mounted on the ISS. The camera is looking toward Earth with an occasional solar panel passing through the view.

  • Black = on the nighttime side of the Earth
  • Gray = The ground support computer has stopped sending video to USTREAM (IBM Video) and will be reset shortly.
  • Moving spots of light in the dark = lights on the surface of the Earth. This camera can see cities at night (if not cloudy)
  • Non-moving spots in the image = damaged or bad pixels

ISS High Definition Live Streaming Video of the Earth

After HDEV stopped sending any data on July 18, 2019, it was declared, on August 22, 2019, to have reached its end of life. Thank You to all who shared in experiencing and using the HDEV views of Earth from the ISS to make HDEV so much more than a Technology Demonstration Payload!

The High Definition Earth Viewing (HDEV) experiment mounted on the ISS External Payload Facility of the European Space Agency’s Columbus module was activated April 30, 2014 and after 5 years and 79 days was viewed by more than 318 million viewers across the globe on USTREAM (now IBM Video) alone.

Human Space Flight Sighting Opportunities

As the HDEV feed is not usually recorded and publically archived, we suggest the use of open-source or commercially available screen recording software for capture of video segments.
