First of all, do you know what ISS is? The International Space Station is a large science lab floating in the lower orbit of the Earth. Scientists from America, Russia, Europe, Japan, and Canada have built it together. It is about 400 kilometers above the earth and revolves around the earth at a speed of 28000 kilometers per hour. From this, you can understand that it revolves around the whole earth in just 90 minutes. This means that the people present there see sunrise and sunset once every one and a half hours.

The sun comes and goes every 90 minutes.

Now let's come to the main question. Suppose it is 6 am in India. This means that the sun is rising, but what will be happening on the ISS at that time? The ISS is constantly rotating. It may or may not be above India at that time. If it is above India, the sun may also be out there. But if it is above the dark part of the Earth, like the Atlantic Ocean or South America, then it will be night there. This means that there is no permanent cycle of day and night on the ISS as it is on Earth. There the sun comes and goes every 90 minutes.

What will Shubhanshu Shukla see?

If Shubhanshu Shukla is in the International Space Station, he will be able to see the difference between day and night very quickly. He can see the sun rising and then setting every 45 minutes. Now know what the view will be like? So Shubhanshu will see the sun very bright. There will be no haze on it. From there, the surface of the earth will be seen with a blue-green glow. At sunrise, a bright orange line is seen on the edge of the earth, which is called a thermosphere glow. At night, when the ISS is in darkness, the lights of cities on earth are visible. It seems as if a string of lights is spread.

How do astronauts see time?

On the International Space Station, day and night are counted according to Coordinated Universal Time. That is, the local time zone of any country does not apply here. The crew there gets a fixed schedule. Their time of sleeping, waking up, working, and eating is fixed. Light and darkness on the space station are controlled by artificial lighting.

How is day and night felt?

Because the sun comes and goes every 90 minutes in the ISS, so the sense of day and night is not from the light, but from the program and body clock. Shubhanshu Shukla and his fellow astronauts have been given special clocks and alarms to keep track of time. Biological clocks can get disturbed in space, so they are given scientific simulations of light and darkness.
