從太空看地球

ISS太空站4/30開始拍攝地球即時視訊 可上網收看

** 很漂亮,不看可惜喔! **

依官方消息是為了測試各牌攝影機的性能,任務資訊詳官網:

建議對照 ISS 位置,

若 ISS 飛入地球陰影,視訊畫面是黑色的,
如果視訊畫面是灰色, 表示在切換鏡頭。

Commercial HDTV Streaming Live from ISS

Now, live from space, it's Earth all the time! A new experiment
called the High Definition Earth Viewing (HDEV) was launched on April
18, 2014 in the "trunk" on the SpaceX Dragon spacecraft and has been
set up outside the International Space Station.

The set of four commercial HD video cameras and is now operational,
after being installed on the External Payload Facility of the ESA
Columbus module this week. The cameras and electronics are enclosed
in a pressurized box to provide protection to the equipment from the
harsh environment of space.

Watch the view from the ISS live on-line at:
http://www.ustream.tv/channel/iss-hdev-payload

Please note that the screen will appear black when the ISS is in
orbital night. There also has been some downtime off and on that I've
noted while watching this morning. This may be due to some initial
setup/operation issues, or some occurrences of loss of signal.

(Editor Note: This is not the HAMTV experiment.)


官網說明:

***QUICK NOTES ABOUT HDEV VIDEO***
Black Image = International Space Station (ISS) is on the night side of the Earth.
Gray Image = Switching between cameras, or communications with the ISS is not available.
No Audio = Normal. There is no audio on purpose. Add your own soundtrack.

For a display of the real time ISS location plus the HDEV imagery, visit here: http://eol.jsc.nasa.gov/HDEV/

The High Definition Earth Viewing (HDEV) experiment aboard the ISS was activated April 30, 2014. It is mounted on the External Payload Facility of the European Space Agency’s Columbus module. This experiment includes several commercial HD video cameras aimed at the earth which are enclosed in a pressurized and temperature controlled housing. Video from these cameras is transmitted back to earth and also streamed live on this channel. While the experiment is operational, views will typically sequence though the different cameras. Between camera switches, a gray and then black color slate will briefly appear. Since the ISS is in darkness during part of each orbit, the images will be dark at those times. During periods of loss of signal with the ground or when HDEV is not operating, a gray color slate or previously recorded video may be seen.
Analysis of this experiment will be conducted to assess the effects of the space environment on the equipment and video quality which may help decisions about cameras for future missions. High school students helped with the design of some of the HDEV components through the High Schools United with NASA to Create Hardware (HUNCH) program. Student teams will also help operate the experiment. To learn more about the HDEV experiment, visit here: http://www.nasa.gov/mission_pages/station/research/experiments/917.html


祝 收視愉快 !
