Remember the movie “Men in Black”, where Agent Kay looked through an orbital camera at his beloved watering flowers in the courtyard? The opportunity to see what our Earth looks like from a satellite in real time attracts people from all over the world. Today we will tell you - and show you! - the best fruits modern technologies on Earth observation.
Attention! If you see a dark screen, it means the cameras are in the shadows. Screensaver or gray screen- no signal.
Usually we only get static satellite maps, frozen in time - details have not been updated for years, and an eternal summer day reigns outside. Isn't it interesting to see how beautiful the Earth is from a satellite online in winter or at night? In addition, the quality of images of some regions of Russia and the CIS leaves much to be desired. But now all this can be solved in one fell swoop - thanks to , Earth online from a satellite in real time is no longer science fiction. Right on this page you can join thousands of people who are now observing the planet.
At an altitude of 400 kilometers above the planet, where the station is permanently located, NASA installed one developed by private companies. The astronauts themselves or at the commands of the Mission Control Center direct the cameras from which data is transmitted. Thanks to manual control, we can see what the Earth looks like from a satellite online from all sides - its atmosphere, mountains, cities and oceans. And the mobility of the station allows you to view half of the globe in an hour.
How does the broadcast happen?
Thanks to the fact that the cameras are located at the International Station, even minor details are visible to us, which are commented on by scientists, astronauts and professional journalists. However, our Earth is visible online from a satellite in real time thanks to the work of a whole complex of people and machines - in addition to the already mentioned astronauts and the Control Center, satellite communication technologies are involved in the process, solar panels power supply and technical specialists involved in data translation and decoding. Accordingly, the broadcast has its own nuances - knowing them will help you see more and better understand what is happening on the screen.
Our observation point, the orbital station, moves at enormous speed - almost 28 thousand kilometers per hour, and circles the Earth in 90-92 minutes. Half of this time, 45 minutes, the station hangs on the night side. And although on approach the solar panels of the cameras can be powered by sunset light, in the depths the electricity disappears - therefore it is not always available from the satellite. At such moments, the broadcast screen turns gray; Just wait a little and you will be watching the sunrise with the astronauts.
In order to find best time for observations, you will need our special map of the Earth from a satellite - it marks not only the time of passage of the space station, but also its exact position. This way you can find out when to see your city from space heights, or find a station in the sky with binoculars or a telescope!
We have already mentioned that astronauts and ground control can change the aiming of cameras - they perform not only an entertaining, but also a scientific function. At such moments, planet Earth is not accessible from a satellite in real time - a black or blue screensaver appears on the screen, or already captured moments are repeated. If there are no interruptions in satellite communications, the station is located on the day side of the planet, and the background suddenly changes, then the cameras are filming areas inaccessible to the public due to international treaties. Secret objects and forbidden territories are closed on static maps, skillfully hidden by photo editors or simply erased. All that remains is to wait for the moment when the situation in the world relaxes, and there will be no secrets from ordinary citizens.
Hidden Features
But don't be upset if the camera isn't working right now! When planet Earth cannot be shown online from satellite, astronauts and NASA find other entertainment for viewers. You will see life inside the International Space Station, astronauts in zero gravity, who talk about their work and what kind of satellite view of the Earth will be shown next. They even allow you to look into the impressively large Mission Control Center. The only negative is that even the speech of Russian cosmonauts is translated into English so that it can be understood by the American employees who manage the Center. It is currently not possible to turn off translation. Also, don’t be surprised by the silence - comments are not always appropriate, and there is no constant sound accompaniment yet.
For those who are predicting the route of cameras using the capabilities provided by a real-time satellite map of the Earth, we have advice - check the date and time settings on your computer. The server that updates the map uses the given International Station motion formula and the time zone of your IP address to predict the position of the orbital cameras. What does the Earth look like from a satellite? online map judges solely by device time. If your clock is slow or fast relative to the time zone, the station will move east or west accordingly. The use of proxy servers and anonymizers will also affect the results.
You are a participant in a scientific program
Surely you have noticed that the quality of the image of planet Earth from space, live broadcast from a satellite, often changes - the image is covered with squares or lags behind audio track. In most cases, it is enough to check the speed of your Internet connection, disable other videos and programs for downloading files, or click on the HD button in the broadcast window. However, if there are interruptions, it is worth remembering that the planet is visible alive only thanks to a large-scale scientific experiment.
Yes, yes - the video on this page is transmitted for a reason. The cameras installed on the International Space Station are part of the High Definition Earth Viewing program (from English: view of the Earth from a satellite in high resolution), which is still being improved and developed. The cameras are installed by astronauts in conditions isolated from cold and dust, but they are exposed to harsh radiation from the outside. Scientists are experimenting with the difficulties of seamless data transmission in space, ensuring that a map of the Earth from a satellite good quality existed not only motionless, but also living, dynamic. The results will help improve existing channels and create new ones - even in Mars orbit in the foreseeable future.
So let's stay in touch - new things appear in the world of space every day!
