On March 12, 2025, all preparations were done at NASA’s Kennedy Space Center. Four astronauts were also seated in the Falcon Nine rocket of SpaceX. After a journey of 9 hours, they were to reach the International Space Station, and Sunita Williams was to return from there, but the launch was stopped on the spot, and Sunita’s return was put on hold for 9 months. Once again, why the search for Sunita’s return mission, when will she be able to return to Earth, and why even the world’s richest man, Elon Musk, cannot bring her back? We will know
NASA and Elon Musk’s company Space One together planned the return of Sunita Williams and Bhuj Wilmer, for which Space’s Dragon capsule was to be used, in which Space’s rocket Falcon Nine would be sent into space, but there was a problem with the hydraulic system with the ground clamp R of the Falcon 9 rocket. With its help, the rocket is made to stand upright in the launch position, and energy is obtained for that takeoff. How does the rocket system work? Due to a fault, the mission was aborted one hour before launch. After this, all four astronauts, including McLaren and Nicol, came out of the Dragon capsule. So will Sunita Williams never be able to return to Earth? Sunita’s return will happen as planned. There is only a delay of two days in this. According to NASA, the Falcon 9 rocket will dock with the International Space Station at 7:00 pm on March 14 as per US time and at 11:30 pm on March 15. If everything goes well, Sunita and Bhuj can be brought back to Earth by March 19. US President Donald Trump had entrusted Elon Musk with the responsibility of bringing back Sunita and Bhuj, who were in space. In such a situation, the question arises whether Mast is also failing to bring Sunita back. On this, experts say that it is not that Mast is proving unsuccessful in bringing Sunita back. The reason for the delay in this mission is technical problems. Musk started working on it only after the order of President Trump. Now let us understand what is the distance of this return to Earth. The distance of the Earth is 400 kilometers. It takes about 3 hours for the spacecraft to reach from here. After unlocking it, the direction and speed is given by the system. At the time of re-entry into the Earth’s atmosphere, the speed of the spacecraft is 28000 kilometers per hour. If the angle of the spacecraft is wrong during this time, then it will not be able to enter the Earth’s atmosphere and will remain in space for eternity. The temperature of the spacecraft due to friction in the Earth’s atmosphere reaches up to 1500 degrees Celsius. In such a situation, if there is a technical fault in the spacecraft, it can burn. Even after returning on 19 March, things will not be easy for Sunita. After spending 9 months in space, it may take her a year to become normal. That’s all in today’s accident.
Falcon-9 Rocket takes off to bring Sunita Williams and Barry Wilmore back to Earth
NASA and SpaceX have launched the Crew-10 mission to bring back stranded astronauts Sunita Williams and Butch Wilmore. In this mission, the Falcon 9 rocket carrying the Dragon spacecraft took off from NASA’s Kennedy Space Center. A Crew Dragon capsule was launched with a Falcon 9 rocket from the Kennedy Space Center in Florida. In this mission, a team of four members began their journey toward their target.
Efforts to bring back American astronauts Sunita Williams and Butch Wilmers are continuing. The American space agency NASA and SpaceX have launched a mission to bring back the two scientists on 433. In the mission, the Falcon-9 rocket carried the Dragon spacecraft under the Crew 10 mission. Four new astronauts have also been sent on this mission. Sunita Williams and Butch Wilmers have spent 281 days in space so far and according to the information that is coming out, their health has started deteriorating and in the midst of all this, now a rocket has been sent from here to rescue them. Astronaut Sunita Williams has come one step closer to returning home. SpaceX’s Falcon-9 rocket was launched into space with Crew Dragon. This SpaceX rocket Falcon-9 and Crew Dragon from America were critical because it has the replacement crew after whose departure, astronaut Sunita Williams and astronaut Butch Wilmers will be able to return to Earth. The rocket’s leap off happened perfectly, and after 10 minutes, four astronauts, two American, one Japanese, and one Russian cosmonaut reached space. Now they will travel in space for 28 hours, of orbit, and then on Sunday morning, they will dock at the International Space Station. So this is a big step for the return of Astronaut Sunita Williams and Astronaut Butch Wilmore. Let me tell you that Indian astronaut Sunita Williams has been in space for more than a month now. She went to space on the maiden flight of the Boeing Star Liner, which they had built. Something went wrong in the Boeing Star Liner and after that NASA returned it empty-handed and placed Astronaut Sunita Williams and Butch Wilmore in space on the International Space Station which is the size of a football field for an extended stay. This was an eight-day mission of Astronaut Sunita Williams Butch Wilmore. Now it grew to eight months and then nine months. Now, 28 hours after this launch SpaceX Crew Dragon will dock at the space station, and after a few days, astronauts Sunita Williams and Wilmore will return from space. NASA believes it will happen now, so it will happen on March 19 or 20, Indian time. According to this, astronauts Sunita Williams and Wilmore will be able to return to Earth, so a space mission has been sent from here by NASA to rescue Sunita Williams and her companions.
Sunita Williams returned to Earth, this is the detailed account of her return from space to Earth
Astronaut Sunita Williams and Bhuj Wilmar and two other astronauts have returned to Earth in Space One’s Dragon capsule. These two astronauts, who went to the International Space Station for just eight days in June last year, have been able to return after 9 months. The Boeing Starliner that was going to bring them back to Earth had malfunctioned, so they had to wait so long. They finally landed safely on the coast of Florida. After being unlocked from the International Space Station, it took a long 17 hours to reach Earth.
Know how the journey was and what happened after the capsule was pulsed down. The parachute opened and then Splash Town. According to Indian time, at 3:27 am on Wednesday, the capsule carrying the astronauts landed in the sea near the coast of Florida. After coming to the surface of the sea, the control center welcomed the astronauts and said, Nick Alex Bhuj Sunny, welcome home from Space One. Commander Nick replied happily, everyone’s faces in the capsule lit up But there is a smile on what happened just before this placid downfall? While entering the earth’s atmosphere, the speed of the Dragon capsule was 17000 miles per hour, which was rapidly slowed down at intervals of a few minutes. The temperature of 2000 degrees and the heat shield was so dangerous that this journey was so dangerous that when the capsule entered the earth’s atmosphere, the communication blacked out, which was around 3:20 after entering the atmosphere. The temperature of the plasma shield of the spacecraft reached 1927 degrees Celsius, but the heat shield proved to help protect the astronauts from such intense heat. At around 3:21 minutes it became autonomous, that is, the astronauts were not controlling it. During this time, they were able to see all the activities on the touch screen in front of them. At around 3:24, two parachutes of the Dragon capsule opened, which slowed down its speed further. During this, there was a strong shock and the speed of the capsule slowed down further. After this, two more parachutes opened. What happened after landing in the sea? Just after the capsule landed in the sea, dolphins were seen circling the capsule in the water. The recovery team present on the spot reached the capsule from the fast board and first took stock of the security and then removed the parachute. After this, SpaceX’s recovery port was reached, which was stopped at a distance of 2 miles from the landing side. When the spacecraft was returning, the sky was completely clear and blue. After this, the capsule was brought to the safety boat with the help of the zodiac signs. When the dragon’s side of the capsule opened, the whole world started waiting to get a glimpse of the astronauts. After this, through NASA’s live pictures, people around the world saw Sunita Williams and her companions coming out. Just before coming out of the capsule, Sunita Williams and Wilmer expressed their happiness by waving their hands in the air towards the camera. After spending about 286 days in space, Sunita Williams and Bujh Wilmer breathed fresh air on Earth. While living on the International Space Station for about 9 months, both the passengers saw sunrise and sunset 16 times every day and it can be imagined how challenging it must have been for them to adjust to this. How is the health of the astronauts?
Steve Stich, manager of NASA’s Commercial Group Program, said that the health of the astronauts is fine. He said that the astronauts will stay on the recovery ship for some time and then they will be taken to the spacecraft. He thanked his team and praised American billionaire Elon Musk’s company Space One for adapting itself according to NASA’s needs. However, the astronauts are undergoing medical checkups and after this process is completed, they will be allowed to meet their families. Deputy Associate Administrator of NASA Space Operation Mission Director S Jayal Mental Bano said that while on this mission, they did research for 900 hours and during this time 150 scientific experiments were done. She described the experiments done by the NASA astronauts as beneficial for the country and expressed hope that these would prove helpful in achieving the goal of landing humans on Mars by the end of this decade.

Sunita Williams and Butch Wilmore were kept under medical supervision after returning from Space-Explained
Sunita Williams Are Which Will More Mahesh went on a mission of 8 days but due to technical problems, this mission was stuck for 9 months i.e. Sunita Williams and Bhuj Bill Mal remained in space for 286 days but the record of staying in space for a long time is in the name of Russian astronaut Valery Pulia. According to the New Mexico Museum of Space History, Valery had spent 437 days 17 hours, and 38 minutes in space. During this time, he orbited the Earth 7075 times. Valery Pulia had studied astronautical medicine at the Moscow Institute of Medical and Biological Problems. Pulia is considered very important for the study of the effect of space on the human body.
What is the effect of microgravity? 62-year-old Wilmer and 59-year-old Williams said they are happy to stay in space for a long time. Both are retired Navy captains and have vast experience in space. Sunita Williams and Although Wilmod has returned safely to Earth from space, he will not be able to live a normal life yet. After returning from space, one has to go through a complete recovery process. Both were brought directly from the capsule on a stretcher and sent for medical supervision. This is a routine process because in microgravity the muscles start weakening, the balance of the body gets disturbed and fluids start shifting in the body. Microgravity is the state in which humans and objects become weightless. Since gravity does not work in space, that is why astronauts become weightless, but what is its effect? Experts say that staying in space for a long time has a direct effect on health. Staying in space for a month changes the body and psychology of a person. The biggest change comes when the astronauts are in microgravity. In this situation, the astronauts start floating inside or outside the spacecraft, that is, they are seen hanging in the air. During this time the muscles start weakening because they are not used. You cannot even use any exercise equipment in such a situation. NASA says that due to this the bones also start weakening. It handles the outside of the body and provides support, but in space, without the gravity of the Earth, the bones lose an average of one percent to 1.5 percent of their mineral density every month. Apart from this, without proper diet and exercise, the muscles of astronauts in microgravity start becoming thinner than on Earth. NASA also says that in microgravity, the blood and cerebrospinal fluid start shifting from bottom to top. In such a situation, there is a strong possibility of change in the shape of the eye and brain. There is also a risk of kidney stones due to dehydration or calcium removal from the bones. After staying in microgravity for a long time, it is very difficult to adjust to the gravity of the earth. In such a situation, as soon as the astronauts come to Earth, they are kept under medical supervision. Balancing the body in gravity from microgravity and behaving accordingly is a difficult test. For this, the challenge of walking straight, standing straight, and maintaining the balance of the body has to be faced every day.
Why was Sunita Williams taken out of the Dragon capsule and carried on a stretcher?
Do you have decided that it is open for the first time set in September Astronaut Sunita Williams has returned to Earth after spending 286 days on the International Space Station. On March 19, according to Indian time, at around 3:27 in the morning, with Will Moore and two other astronauts, she came to Earth from Space One’s Dragon spacecraft. After press dawn, NASA’s rescue team took the astronauts out on stretchers from the Dragon capsule, but why was the structure needed? Just as returning to Earth is a challenging journey, in the same way, after spending a long time in space, astronauts face many difficulties on returning to Earth. According to scientists, after spending a long time in space, astronauts are often unable to stand or walk normally, so immediately after coming to Earth, they cannot even go home to meet their families. Now we know what changes take place in the bodies of astronauts after returning to Earth from space, how they recover from it, and how much time it takes. Astronauts live in space in zero gravity. They see the sunrise every 90 minutes. This means that the International Space Station The station orbits the Earth every 90 minutes. This sounds interesting, but it causes many problems in the bodies of astronauts, which can take days, weeks, or even months to recover from. NASA astronauts Scott Kelly and Christina Koch are the first Americans to spend almost a year on the space station. A study called Twin Study was conducted on Scott Kelly and his twin brother and retired scientist Mar Curry to investigate the changes in the body during time in space. Much new information was obtained from this study. Astronauts who spend a long time in space mainly face the problem of weakening of bones. This is because due to the zero gravity of space, the heart and hips are not used as much as they are on Earth, so as the day passes, the pain decreases by one to one and a half percent every month. Loose muscles and flat feet are also a big problem. Due to the lack of gravity in space, the fluid in the body moves upwards towards the head. This can cause eye pressure and vision problems. According to NASA, long-term space travel causes weight loss. Apart from this, neurological changes, vision problems, and skin problems are also caused. Indian Space Dr. S. Pandian, former director of Satish Dhawan Space Center of research organization ISRO, says that when we are in space, our height increases. On Earth, gravity pulls the spine downward because there is no gravity in space, so the disc is pulled upward, due to which the height increases. NASA told on its website that if caution is not taken, then there is a possibility of kidney stones due to dehydration in the body. According to NASA, even after returning to Earth, astronauts can feel as if they are floating in space while they are on Earth. Apart from this, it is also possible that neural tube defects may occur due to pressure on the eardrum. Dr. Pandey says that after a long space journey, astronauts are not able to stand straight, so they have to be taken on a stretcher. So what treatment and training is given to astronauts? Astronauts are kept in NASA’s center for about 45 days. They are given training to be physically and mentally healthy. Dr. Pandian says that astronauts are given different training in four stages. The first stage is warm-up, after this, they are given stretching. Then training is given in cardiovascular exercises. After this, the passengers do the same exercises that they have been doing on the space station. All this is done under the supervision of a team of medical experts. Dr. Pandey says that it takes about 6 months for the astronauts to recover completely. However, according to NASA, it is not possible to completely compensate for the damage to the bones due to staying in space. According to the space agency, the risk of fracture always remains. Apart from this, if we talk about mental health, then the level of hormones in the body increases due to many reasons in space. Due to this, mental fatigue occurs in space. Staying away from family for a long time and not being able to participate in emotional moments with family members can also affect the mental health of astronauts.
Sunita Williams: What difficulties do astronauts face in sleeping after returning to Earth from space?
For 9 months, space was their home. Now that two NASA astronauts Sunita Williams and Bhuj Bill Moore have set foot on Earth, everyone has heaved a sigh of relief. But for these two astronauts who stayed away from Earth for so many months, will everything be the same as before or will they have to make new adjustments? The first glimpse of the SpaceX capsule was returning to Earth. After the third entry into the Earth’s atmosphere, the parachutes opened and while coming down, its speed started slowing down. Inside it is Witch Will Moore. Sunita Williams and her two companions from the Karoo. Sunita has finally come home. The NASA astronauts had reached the International Space Station in June last year. They were supposed to spend a week there, but due to a technical fault in their speechcraft, they had to stay there for a long time. They made full use of their time, but both of them admitted that they kept missing the little things in life. I think you miss the smell of grass and such little things which you don’t get here. I am waiting to meet my family and dog and to go for a walk in the ocean. I am waiting to spend 286 days in space. Sunita’s health must have been affected as well. Despite exercising in the space, her muscle and bone density must have decreased which will take some time to recover. But there are some benefits of being weightless in space. When you return from space, it is very difficult to sleep because you have been swimming for 6 months and are getting a good sleep. There is no stress on the body. Then when you take it initially, you feel the pressure points. It is a problem but then you get used to it. Apart from the rescue team, a group of dolphins also reached there. The spacecraft along with the astronauts present in it left from there and finally, they breathed fresh air. Sunita looked very happy after returning after a long time. There is a smile on Bhuj’s face too and he is very happy to return home. The capsule has done its job. Now he and Sunita have returned to their family.
Sunita Williams What will health and life be like when she returns to Earth from Space?
Sunita Williams and Buchwel Mor spent 286 days in space, the longest. NASA astronaut Frank Rubio spent 371 days in space. In September 2024, two Russian cosmonauts, Anton and Niko Laitchaev, returned from 374 days in space at the International Space Station. But who knows who has stayed in the space station for the longest time? Russian Cosmonaut Gallery Polykop In the 1990s, they spent 437 days in the Mir space station. What are the effects on the body after staying in space for such a long time? What happens to these astronauts after returning to Earth? We will understand whether they can immediately resume their normal lives after staying in space for a long time. The muscles in the astronauts’ bodies, brains, eyes, and all of these are affected by a long stay in space. Due to the lack of gravity, the amount of muscle mass in the limbs and bone density starts to decrease. There is not much that helps us to maintain a straight posture. The muscles in our back, neck, stomach, and thighs are most affected. The muscles do not work and they start to weaken. After just two weeks in space, the bone mass decreases by 20 percent, and after two to six months, it can decrease by 30 percent. In addition, the skeleton does not have the same workload on the bones as on Earth, so the bones start to become brittle and their strength starts to decrease. Six astronauts lose up to ten percent of their bone mass, which increases the risk of fractures and takes longer to heal. After 371 days in space, it can take four years for the bones in the body to fully recover, and that is why astronauts focus on exercising for two and a half hours a day while in space. On Earth, gravity causes the blood in our bodies to flow downward, but in space, this process is disrupted and more blood than usual accumulates in the head. Some of this fluid can accumulate in the back of the eye and around the optic nerve, causing swelling. This can affect or affect the structure of the eyes. This can start to happen after a short stay in space, but this risk also increases with increasing duration. NASA’s Frank Stearns, who participated in a study during his 371 days in space, was given some exercise tips. This study was about how much fitness can be maintained with the help of these devices because in the future, when long-distance space missions are launched, astronauts will be able to carry only small, lightweight devices. Due to the lack of gravity in space, astronauts may feel a little taller or have increased height because their spines expand slightly. This can lead to back pain while in space and slipped discs after returning to Earth. Maintaining weight in space is also a challenge, and that is why NASA tries to provide these astronauts with nutrients. NASA astronaut Scott Kelly has a twin brother Kelly was on the International Space Station for 340 days. When he returned to Earth, he had lost 7% of his body mass compared to his twin brother on Earth. In space, 3 million red blood cells are destroyed every second, while on the ground, only 200,000 cells are destroyed, but the body replenishes them if this does not happen, astronauts become seriously ill in space. After returning to Earth, these astronauts experience weakness and fatigue. They become aware of this, so their muscle strength also decreases. The magnetic field around the Earth protects them from radiation in space, but they have to face a large amount of radiation, which affects DNA. The risk of cancer also increases. Neurological damage occurs, meaning that the nerves in the nervous system are affected. It can have side effects. Heart function is also likely to be affected. The immune system is also likely to be affected. So what is done after the astronauts return to Earth? After landing, the recovery team takes the astronauts out of their floating capsule into the sea. This team also includes a medical team. During these days, they are brought to the space station and then a reconditioning plan is drawn up for about 45 days, meaning that the exhausted body is helped to adapt to the Earth’s environment once again. During this period, the changes in the body of these people are recorded. Studies are also conducted to try to bring their bodies back to the physical level that the astronauts had before going to space. Although most of the recovery takes place within 45 days, it is necessary to repair the bone damage and to recover from the time they were in space. However, the process of reabsorbing the lost calcium can take time, and this process continues for the next few years.
ISS Shutting Down: Why is ISS shutting down?
American National Sunita Williams and Will More have returned to Earth after 9 months. Sunita Williams and her companion Burj Will More were on the International Space Station for 9 months. Now NASA wants to shut down the ISS i.e. International Space Station, but why? Let us know. The International Space Station is once again in the news and this time the discussion is that the mission of the International Space Station will end in 2031. ISS has been a symbol of the progress of the space industry since 1998. The International Space Station is located at an altitude of about 400 to 415 km from the Earth. It is 109 meters long, almost equal to a football field, and weighs 4 lakh kg which is 400 tons i.e. about 80 African elephants. It is also considered a six-bedroom apartment. More than 40 space programs have taken things from the Earth and deposited them in space, so what will happen if this huge space station gets damaged? Well, the International Space Station rotates at a speed of 17,500 miles per hour, which means it revolves around the Earth about 16 times daily. It revolves around 100 km, that is, it completes one revolution every 90 minutes. Such a large structure rotating at such a high speed and suddenly going out of control and entering the Earth’s atmosphere sounds very terrifying and to avoid such dangerous situations, NASA has decided to shut down the International Space Station by 2031. Why will the ISS be shut down? Well, the reason for this is quite clear. The International Space Station is getting old now. Think for yourself that it was built in 1998. Russia, America, Canada, Japan, and many European countries together built this space station in 1998. Later, it was also updated in many different phases. It was initially designed to run for only 15 years, but given the success of scientific research and international cooperation in the space industry, its time was extended. Finally, during the administration of former American President Joe Biden, in 2021, it was decided to extend its time till 2030. However, in 2021 Itself a warning was issued by Russia Regarding the space station, Russia had said that the condition of its hardware and devices may be such that it cannot be repaired. Russian cosmonaut Vladimir Solvoy said that 80% of the instrumentation system of the Russian segment of the ISS has become outdated and small cracks are also visible which will increase with time. Meanwhile, Elon Musk posted on X in February that the ISS should not be given time till 2030, but it should be closed in just two years. He wrote that President Trump should decide on this. Elon Musk wrote Court unquote Now it is necessary to start the work of removing the ISS from the orbit. The purpose for which it was built has now been completed. Now we should focus on Mars. So how will the ISS be destroyed? As already said the International Space Station is the size of a six bedroom. When it revolves around the Earth, its orbit is gradually affected by the drag of the atmosphere. If it is left like this, then due to the effect of the Sun, it will move away from its orbit within one or two years and start falling towards the Earth. This can become a big threat to the people living on Earth. Therefore, the reboost process is being carried out so that the space station can be kept functional. NASA says that the work of shutting down the ISS will begin soon. As a first step, the ISS will be allowed to fall slowly on its own due to the drag of the atmosphere, meaning the reboot process will be gradually reduced. Along with this, the work of slowing down the speed of the ISS will also begin. For this, the spacecraft and the other proportion modules like the Progress Russian spacecraft present in the space station will be used. Its non-essential modules will be separated and removed one by one in orbit. From 2026 to 2030, the height of the ISS will be gradually reduced by 415 km. It will be reduced to 100 km. After that, after reaching 280 km, it will be brought down to 120 km with the help of a special spacecraft. If this plan works properly, the ISS will reach a height of 120 km. From there, the ISS will collide with the Earth’s atmosphere at a tremendous speed of 2900 km/hour. But NASA says that as soon as it collides with the atmosphere, most parts of the ISS will burn and get destroyed due to the extreme temperature and heat. The remaining part will fall at Point Nemoor, a place in the Pacific Ocean. NASA says that there is no human population here, so it will not be dangerous for anyone. Most unwanted spacecraft are also dropped here. Well, in June 2024, NASA chose Elon Musk’s company Spcex to remove and destroy the ISS from orbit. For this, a contract of 843 billion has also been signed with SpaceX. Well, if the ISS ends, what will be its alternative? NASA says that before the ISS is closed, private space stations will become operational. This will enable commercial space services to start in low Earth orbit. For this, agreements are being made with companies like Axiom Space and Blue Origin. NASA also says that after 2031, it will focus on going out of low Earth orbit, such as sending human operations to the Moon and Mars. Other countries are also preparing to build their space stations. India is also included in this. India is planning to build its own space station Indian Space Station by 2035. Former ISRO Chairman S Somnath had said last year that its first part will start functioning by 2028. Part is launched India will be able to fully operate its space center China sent the first module of its space station Tigong which means Heavenly Palace into orbit in 2022 While the ISS has been built by many countries together, China built its space station alone China says that their Tigong Well is ready to replace the ISS after 2031 The ISS is a home in space for astronauts The ISS is equipped with oxygen generating units Talking about water, there is such technology in the ISS that captures moisture in space and converts it into water There is even such equipment that can convert urine into potable water Currently, there is enough ration in the ISS to handle the demands of the current astronauts and all the food supplied to the ISS is cooked at NASA’s Space Food Systems Laboratory in Houston, especially keeping in mind the nutritional requirements and appetite I hope you understood from this That would be why NASA wants to dismantle the ISS
What happens to the clothes and items astronauts use in space? Explained
Pokemon Board After spending 9 months in the International Space Station, Sunita Williams returned to Earth on March 19. How did she stay in space for so long? What could be the effect on her health? All these things are being discussed a lot, but one question is also what happened to the clothes she wore and the things she used in space? Now clothes cannot be washed in space, so astronauts change their underwear every 2 days and other clothes every few days or once a week. There is no facility to reuse the dirty clothes used during the stay in space, so eventually they turn into garbage. Along with clothes, the things that astronauts use for their coffee and food also turn into garbage. Water and shield locks are provided to astronauts with straws. Juice and coffee are also drunk in similar bags, but all these are disposable and eventually turn into garbage. Similarly, food items are packed and sent in airtight containers, which are designed in such a way that they do not spoil for a long time. That is why later these containers also go into the garbage. Apart from this, urine and stool also get deposited as waste. In this, urine is filtered and reused as water, but stool gets deposited as waste. According to NASA, four astronauts who spend a year in space produce about 2500 kg of waste i.e. garbage.
Now let us understand what happens to all this garbage. A lot of garbage accumulated on the International Space Station, which includes the clothes worn by the astronauts, leftover food, their stuff, old batteries thrown away, and other things. Usually, the necessary things for the astronauts living on the space station and other things are sent from the spacecraft from time to time. When the cargo of the spacecraft being sent gets empty, they keep their garbage in it and then it is unlocked. The spacecraft filled with garbage or which is outside the dock keeps orbiting the Earth, sometimes it enters the orbit and falls on the Earth. Many such incidents have come to the fore. In this way, urban pieces of debris are floating in space. Dealing with this space debris is a big challenge. 4 October In 1957, the first rocket was launched into space. Space yoga started with the launch of the Sputnik One satellite. Since then, man has sent more than 10,000 spacecraft into space. Every time a spacecraft is sent in this way, a lot of garbage accumulates in space. There was always a fear that if the debris continued to accumulate in space like this, an accident may happen and this also happened. On 11 February 2001, satellites Cosmo 2251 and Iridium 33 collided with each other. Every time a rocket is launched into space, a lot of garbage accumulates there. Not only this but thousands of satellites are also orbiting as junk. Every satellite launched into space has a life span. After their life ends, they turn into garbage. The United States launched a satellite called Vanguard Two in 1958, which is still floating in space as junk. How will this garbage be dealt with? ISRO has made some efforts for this because millions of pieces of debris are circling in space. Therefore, there are apprehensions that they will collide with each other and accidents may occur. The satellites operating on it may be affected. The space station may also be damaged by this. Keeping this in mind, discussions were held at the international level and the main discussion was about what should be done with those satellites which have become inactive and whose service life has ended. As a solution, it was suggested that if the satellite is launched in the direction of the Earth’s atmosphere and is orbited, then it will face continuous friction and will burn completely. Apart from this, efforts are being made to create a web-like system in space so that all the debris can be collected and removed simultaneously.
How to Become an Astronaut? How to become an astronaut in NASA, ISRO?
When someone asked you when you were a child what you wanted to be when you grew up, what should you do to get a sure answer? If you want to go into space and work floating in space, what do you have to do and what education do you have to get? Let’s understand exactly how ISRO and NASA astronauts are selected. NASA carefully selects astronauts for its various human space missions. When NASA invites applications for human space programs, American citizens and employees of all three branches of the military can apply. The Astronaut Selection Board is responsible for selecting astronauts in NASA. Often, armed forces personnel and officers are selected as NASA astronauts, but along with them, ordinary citizens can also be eligible for space missions. So what are the qualifications for that? The qualifications for becoming a NASA astronaut are that the applicant must be an American citizen. He must have a bachelor’s degree in science, technology, engineering, or mathematics from a recognized college.
Along with this, degrees in biological science, physical science, and or computer science are also equally important. They are also considered bad for this. A medical degree is also considered bad for this. After graduation, it is enough. Work experience is also necessary. After graduation, at least two years of experience as a pilot in command of a jet aircraft or 1000 hours of experience or a flying application should be required. To fly in space for a long time, you have to pass a NASA physical test. In this test, your vision is checked, along with blood pressure and height are also measured. Interviews of candidates are held at NASA’s Johnson Space Center in the United States, and after the interview, new NASA astronauts are selected and then sent for training. This training is given at the Johnson Space Center and it is two years. It includes spacewalking, how the work on the space station works, flying the T38 jet aircraft, and how to use robotic hands, i.e. robotic arms. Apart from this, many other skills including space work, and life-long living school timing are taught. These astronauts are also given microgravity training in a modified jet aircraft to withstand the stress of the environment. This training is very important because there is no gravity in space. If there is any malfunction in the system, then how to identify it and how to repair it is also given in this training. A model of the ISS has been prepared for training at the Johnson Space Center. ISS stands for International Space Station. Important information is also given here about how to prepare food in space, use and maintain equipment, use cameras, and do various other tasks. If someone completes this training, he is appointed as an astronaut in NASA. But yes, those who could not complete this training are also given work in other departments at NASA. When Sunita Williams was selected for NASA in 1998, she had been working in the US Navy for 11 years and had flying experience flying thirty different aircraft. She has a degree in Physical Science from the US Naval Academy and has also done graduate studies as a Sect of Technology. All this happened at NASA, but if we want to become an astronaut in ISRO, what is ISRO currently doing? The mission is being prepared and this will be India’s first human space mission, in which three astronauts will participate who will stay in space for three days and return to Earth. Four pilots of the Indian Air Force have been selected as the first astronauts for this mission. Prashant Sair, Ajit Krishna, Angad Pratap, and Shubanshu Shukla have been selected for this mission after a long selection process. These astronauts have been trained in Russia for 13 months and are now undergoing training at ISRO’s Astronaut Training Center. After this Gagan mission, ISRO plans to send astronauts to the moon by 2040.
