Sunita Williams Return: इंटरनेशनल स्पेस स्टेशन वो अंतरिक्ष में मौजूद वो प्लेटफॉर्म है जहां अंतरिक्ष जाने वाली 'सवारियां' उतरती हैं, यहां पर रहती हैं और विज्ञान के बड़-बड़े एक्सपेरिमेंट करती हैं. लेकिन धरती से यहां की जिंदगी एकदम ही अलग है. आप ये जानकर अचंभित हो सकते हैं कि इंटरनेशनल स्पेस स्टेशन में 24 घंटे में 16 बार सूर्योदय और 16 बार सूर्यास्त होता है. ऐसा क्यों होता है हम आपको आगे बताएंगे?

00:00International Space Station is a platform in space where astronauts land, stay here and do big science experiments, but the life here is completely different from that of the earth.
00:16You may be surprised to know that there are 16 sunrises and sunsets in 24 hours at the International Space Station.
00:24We will tell you why this happens in the video.
00:28Sunita Williams, an Indian astronaut, has been stuck in this International Space Station for 9 months and is waiting to return to earth.
00:36The good news is that she is about to return to earth soon.
00:40So how is this International Space Station, what is its size and what are the full details, let's know in this video.
00:47So if you think that the International Space Station is a stationary structure like New Delhi Railway Station or Delhi Airport, then you are wrong.
00:56Actually, the International Space Station is not a constant structure, but it is a spacecraft that rotates continuously.
01:04The International Space Station continues to orbit the earth.
01:07If we talk about its height, then the International Space Station is at an altitude of 403 km from the earth and it continues to orbit the earth.
01:16During this time, astronauts are present in it, that is, Sunita Williams has been orbiting the earth continuously for the past 9 months.
01:23If we talk about its speed, then its speed is the most surprising thing.
01:28The International Space Station orbits the earth at a speed of 17,500 miles per hour.
01:35If we say in kilometers, it means that the International Space Station orbits the earth at a speed of 28,163 km per hour.
01:46If we talk about the size, then according to NASA, the size of the International Space Station is as much as a 5-bedroom house or two Boeing 747 jetliners.
01:55A team of 6 people and some guests can stay here.
01:58If we talk about the current situation, then 8 people are present in the space station at this time.
02:02The weight of the space station on earth is 10 lakh pounds, that is, 4,53,592.37 kg.
02:11If all its parts are combined and its size is measured, then its length will be equal to a football field.
02:18The space station includes the experimental module of America, Russia, Japan and Europe.
02:24We were talking that it has 16 sunrises and 16 sunsets.
02:29Let's know why this happens once.
02:31In the International Space Station, you get the experience of seeing 16 sunrises and 16 sunsets in 24 hours.
02:37You can say it in this way that there is a day of 90 minutes here and a night of 90 minutes.
02:43And this happens 16 times in 24 hours.
02:46This happens because the size of the earth is due to the very fast pace of the International Space Station.
02:52The International Space Station orbits the earth at a speed of about 28,000 km per hour.
02:58It takes 90 minutes in this, that is, it took 90 minutes to orbit one.
03:03This means that in 24 hours, 16 circles are placed all around the earth.
03:08Because the International Space Station completes a cycle every 90 minutes,
03:12it means that during each cycle, this space station stays for about 45 minutes day and 45 minutes night.
03:18That is why in every cycle, the International Space Station once sunrises when it enters from night to day,
03:24and once sunsets when it enters from day to night.
03:29Because the ISS orbits 16 times in 24 hours, that is why it sees 16 sunrises and 16 sunsets.
03:36The size of the earth, which is 12,742 km in diameter and the height of the room of the space station is 400 km,
03:44decides how fast the ISS can rotate around the earth.
03:49If the earth is very big, then it takes more time to complete one cycle and the number of sunrises and sunsets can be reduced by 16.
03:58The balance of the earth's shape and the room of the ISS is such that the ISS crosses the day and night parts of the earth every 90 minutes,
04:06which makes it a unique experience.
04:09Now, how old is this International Space Station?
04:14Its first part was launched in November 1998.
04:18A Russian rocket launched the Russian Zarya control module.
04:23After 1.2 weeks, the space shuttle Endeavour and Zarya met.
04:27The space shuttle was taking the US Unity Node.
04:30The crew members connected the Unity Node to Zarya.
04:33In the next two years, more parts were added to the space station until it was ready to stay.
04:39The first group of drivers to the International Space Station arrived on November 2, 2000.
04:46Since then, people have been staying at the space station.
04:50NASA and many partners around the world completed the construction of the space station in 2011.
04:59Meanwhile, there is good news about Sunita Williams.
05:02NASA has confirmed the date of her return.
05:05In a statement on Sunday evening, it was said that space travelers are expected to land on the Florida coast.
05:12According to the time of India, Wednesday was extended to 3.27 am.
05:19Sunita Williams and Butch Wilmore have been stuck at the International Space Station since June.
05:27She had some technical problems with the Boeing airliner.
05:32After that, she could not return to Earth and stayed there for nine months.
05:37So that's all in this video.
05:38In this video, you learned how the International Space Station is.
05:42How big it is and how fast it rotates.
