Everyone knows that fire is also an element among the five elements. You must also know that a lot of oxygen is required for fire to burn. Burning of fire is not possible without air/oxygen. Fire is one of the greatest discoveries of human civilization. If fire had not been discovered today then it is not known how far human civilization would have reached. Now think, what will happen if this fire starts not on earth but in space? It sounds like a science fiction film, but in reality scientists have done in-depth research on this mystery. Let us know.

Can fire occur in space?

For fire to burn on Earth, three things are necessary – oxygen, fuel and heat. Together these three complete the process of combustion. But the environment of space is completely different, because there is no oxygen there. That means, under normal circumstances, fire cannot occur there. Nevertheless, when humans work in a closed system like a space station, air i.e. oxygen is present there and this is where the risk of fire begins.

What is a space fire like?

NASA and other space agencies have conducted experiments with fire in space many times. During a mission, in the Flame Extinguishment Experiment (FLEX), scientists found that the fire burning in space is round in shape, whereas on Earth it rises up in the form of flames. The reason is that there is no gravity in space, so the hot air does not go up and instead of spreading, the flames remain limited to one place.

Extinguishing fire in space is a big challenge

For this reason, it is very difficult to extinguish a fire in space. The gases present in fire extinguishers are specially designed so that they can work even without air. Scientists say that the biggest challenge of fire in space is its slow burning. Because without air, fire does not spread, but it also does not get extinguished, it keeps burning for a long time.

Accidents happened twice in ISS

There were two such accidents in the International Space Station (ISS) in 1997 and 2011 when sparks of fire arose in small equipment. However, due to prompt control system and monitoring, there was no major loss. That is why astronauts are given special training in fire safety and every station has an airlock system, so that if needed, the affected area can be sealed immediately.

The US space agency NASA has banned Chinese citizens from its prestigious research centers. This decision has been taken keeping in mind security, due to which Chinese scientists and students are not able to reach NASA facilities, content and network. This step has come amid growing space competition between the US and China.

New ban on Chinese citizens
NASA said on 5 September that Chinese citizens who have legitimate visas of America were completely denied NASA system and facilities. These people could only work in NASA as a contractor or a student who contributed to research. NASA confirmed that the step has been taken to “ensure the safety of our work”.

Stress increased due to space competition
China’s rapidly growing space plan is worrying America. Already Chinese astronauts are deprived of the International Space Station (ISS), as the US has prevented NASA from sharing data with China. The new ban will also affect scientific cooperation between the two countries.

Charges of visa and espionage
Recently, many Chinese citizens in America have also been accused of espionage. Especially it has become difficult for students studying in science and technology to get visas and enter America. Some Chinese citizens were also suddenly denied participation in NASA’s data system and meetings.

Official statement of NASA
NASA’s press secretary Bethany Stevens said that “we have taken internal action related to Chinese citizens, including restricting physical and cyber security access to our facilities.” NASA executive administrator Sean Dafi said, “We are currently in the second space race. Chinese want to stop us from going to the moon first. It will not be allowed to happen.”

China’s response
The technical director of China’s manned space agency said last year said that American concern is “unnecessary” and Chinese space exploration is the collective mission of humanity. In the US Senate, lawmaker Chandra Abhiyan has also insisted on the need to transport the US before China.

Competition for resources on the moon
This race is not only to reach the moon, but also to control the resources there. The moon contains minerals such as iron, titanium, rare earth metals and helium, which are used in superconductor and medical devices.

The Indian Space Research Organization (ISRO) unveiled a model of the Indian Space Station (BAS) module during the two -day National Space Day celebrations started in New Delhi on Friday (August 22, 2025). India plans to launch the first module of its own manufactured space station, BAS by 2028. With this, India will join the group of selected countries that operate orbital laboratories.

Currently, there are two orbital laboratories- the International Space Station (ISS) operated by five space agencies and the Tiangong space station of China. Under its ambitious plans for the space sector, India is planning to set up five modules of the Indian space station by 2035.

450 km above will be installed in the lower orbit of the earth

The BAS-01 module is expected to weigh 10 tonnes and will be installed in the lower orbit of the Earth 450 km above the Earth. Its main features include indigenously developed environmental control and life support system (ECLSS), India Docking System, India Birthing Mechanism, Automatic Hatch System, Micro -Gravity Research and Platforms for Technology Performance, Scientific Imaging and Audowment for Covenant’s Entertainment.

The Indian space station will also have all the things like propulsion and ECLSS fluid recurrence, radiation, thermal and subtle meteorial orbital debris (MMOD) protection, space suits.

Will give a chance to test the necessary techniques

The BAS is expected to act as a research platform for the study of various aspects of space, life science, medical and internal explorations. This will provide an opportunity to study the effects of subtle gravity on human health and test the techniques required for long -term human presence in space.

Space station will promote space tourism

This space station will promote space tourism and India will enter the commercial space sector by taking advantage of the resources of this orbital laboratory. The BAS will contribute to the ongoing international cooperation and will act as a center for scientific research and inspire the younger generation to make a career in space science and technology.

A huge BAS-01 model of 3.8 meter times 8 meters at the National Space Day celebrations at Bharat Mandapam in New Delhi was the center of attraction.

PM Modi on Shubhanshu Shukla Return from ISS: Prime Minister Narendra Modi welcomed Group Captain Shubhanshu Shukla, who returned from space, on behalf of the country. He said, “I join the country and welcome Group Captain Shubhanshu Shukla, who has returned to Earth after his historical space mission.” Shubhanshu Shukla has become the first astronaut of India to visit the International Space Station (ISS).

PM Modi said that he has inspired more than one billion dreams with his dedication, courage and leading spirit. He described it as another important milestone in the direction of his human space mission ‘Gaganyaan’ in India.

Successful return of 18 -day historical space mission
India’s Group Captain Shubhanshu Shukla has returned safely to Earth after staying at the International Space Station (ISS) for 18 days. He completed this journey under the Axiom-4 mission, which is considered a historical achievement in Indian space history.

Dragon ‘Grace’ returns from spacecraft
Along with Shubhanshu Shukla, the mission also included American experienced astronaut commander Pagi Whitson, Hungary’s Tibor Kapu and Slavos Ujnanski-Visnevsky of Poland. Dragon ‘Grace’ spacecraft flew from ISS at 4:45 pm Indian time on Monday 14 July and did a safe splashdown on earth after a journey of about 22.5 hours on Monday 14 July.

Defense Minister Rajnath Singh congratulated
India’s Defense Minister Rajnath Singh also congratulated Shubhanshu Shukla on his return. He wrote on X, “Successful return from Group Captain Shubhanshu Shukla’s Axiom-4 mission is a proud moment for every Indian. He has not just touched space, but has given a new height to India’s ambitions. His journey is not just personal, but a big achievement of India’s space trip. Many wishes for the future.”

India’s space ambitions got a new dimension
This mission of Shubhanshu Shukla is not only a moment of pride for India, but it is also a strong inspiration for our Gaganyaan and other future space plans. This journey is proving to be a big step towards India’s growing space operations.

After spending 18 days on the International Space Station i.e. ISS, Indian Astronaut Shubhanshu Shukla left for Earth on July 14 at 3 pm. He will land on Earth on 15 July. However, the question arises that after spending so many days in space, Shubhanshu Shukla can fall prey to which disease? Now what are the dangers for them in the Earth’s atmosphere?

How dangerous is the space travel for health?

Space travel is an extraordinary experience for the human body, but it also poses a risk of many physical and mental problems. According to European Space Agency (ESA) flight surgeon Dr. Brigit Goddard, astronauts may have many problems due to micrograti. These include fluid shifts, reduction in bone density, muscles loss and space motion sickness. Shubhanshu Shukla may also face these dangers.

Space Motion Sickness

According to Dr. Goddard, Shubhanshu Shukla experienced space motion sickness in the first days in space, including problems such as heaviness and dizziness. This condition is caused by microgravity, where the balance and direction of the body is affected. At the same time, astronauts may have such problems even after returning to Earth. Usually these problems are cured in a few days, but in some cases this condition may remain for a long time.

According to NASA’s recent research, about 70 % astronauts have to face this condition. However, Shubhanshu is a fighter pilot. In such a situation, his experience has been helpful in dealing with this condition. Despite this, after coming to Earth, he will be monitored in a seven -day rehabilitation program.

Bone and muscles loss

Space in space has a poor effect on bones and muscles. Shubhanshu during his mission performed an experiment called ‘Myogenesis’, in which the process of weakening of the muscles was done in microgravity. Bone density in space may decrease at the rate of 1-2% per month. There is a risk of problems like osteoporosis.

Radiation danger

There is also a risk of radiation in space. Shubhanshu made experiments during his mission to deal with the risk of radiation, which are important for the long future missions. According to Dr. Elizabeth Johns, working at Houston, NASA Johnson Space Center in Texas, cosmic raj and solar radiation in space may increase the risk of DNA loss and cancer. Shubhanshu and his partner Estrainots checked radiation using ‘Red Nano Dosterimeter’, which will provide better security to astronauts in future.

Mental Health and Tension

Mental health is also affected by staying in space for a long time. Shubhanshu made several experiments during his mission, in which the blood flow of the brain and the speed of the eye was studied. These research will help in understanding mental health and neurological effects.

Shubhanshu Shukla, a astronaut of Indian origin, is now ready to return to Earth after spending 18 days at the International Space Station (ISS) and carrying out many important scientific experiments. Under the Axiom-4 mission, he and three other astronauts will start a return journey on July 14. According to NASA, his safe landing on Earth is scheduled on July 15 at 3:00 pm (Indian time).

Dragon vehicle is bringing ‘scientific treasury’ from space

NASA has informed that many rare and important scientific materials involved in this mission are returning from space. These include 580 pounds (about 263 kg) scientific equipment, NASA’s space hardware and data of more than 60 science experiments. These experiments have been done in space and the future space is considered very important for technology and medical science.

Crew return process begins

All scientific experiments of Axiom-4 crew have been completed. Now the process of their return has started. The process of ‘Undocking’ will start from the space station from the space station from 4:35 pm on July 14 at 4:35 pm on July 14.

Who are in the Axiom-4 team?

• The four -member team of this mission is included.
• Pagi Whitson- Mission Commander
• Shubhanshu Shukla- Pilot
• Slavose Uznansky-Visnivsky- Mission Specialist
• Tibor Kapu – Mission Specialist

Shukla arrived with mango juice and carrot pudding in space

This space journey was special for Shubhanshu Shukla in many ways. He has become the first Indian to reach the International Space Station (ISS). Earlier, in 1984, Rakesh Sharma flew into space under Soviet Russia’s Salute-7 mission. Now Shukla has become another Indian to travel space.

In this historic journey, Shukla also took the special sweetness of India with her. Mango juice and carrot pudding. It was the taste of the house for him, who was also supporting him in space.

Dragon spacecraft launched on 25 June

The Dragon Spacecraft was launched on 25 June from the Canedi Space Center in Florida, USA under the AXIOM-4 mission. After a journey of about 28 hours, the vehicle reached the international space station on 26 June.

Indian scientist Shubhanshu Shukla is soon going to return from space to Earth. Shubhanshu, who visited the International Space Station (ISS) under the Exium-4 mission, can land on Earth at around 3 pm on July 15. Union Minister Dr. Jitendra Singh informed that the ignorant process of crew dragon spacecraft will begin on July 14 at 4:30 pm. Now the question arises that how will this exciting journey to return from space to Earth will be completed? Let’s know

1. Urdaccing: Vehicle will be different from space station

Crew Dragon Spacecraft will slowly separate from ISS. This process is called ignorant. It is completely automated, but astronauts monitor it vigilance.

2. Preparation to return to Earth

After ignorance, the spacecraft will move towards the Earth. Then rocket firing will be done through Retrograde Burn so that the vehicle can enter the gravitational area of the Earth.

3. Entry and tremendous friction in the atmosphere

As soon as the vehicle enters the Earth’s atmosphere, it will have to face tremendous heat and friction. At this time the speed of the vehicle will be around 28,000 km/h, which will gradually decrease while descending.

4. Parachute safe landing

After entering the atmosphere, first small and then large parachutes will open, which will significantly reduce the speed of the vehicle. This process ensures the safe splashdown landing of the vehicle.

According to NASA, if the weather remains favorable, Shubhanshu Shukla and his party will land in the sea near the California coast. NASA will also broadcast this landing live.

5. Return time and recovery

The process ranging from ignorant to splashdown may take a total of 12 to 16 hours. The crew dragon usually descends into the Atlantic Ocean or Gulf of Mexico. The recovery team of Space X immediately arrives and lifts the vehicle on the ship and takes the passengers out safely.

6. What is Shubhanshu Shukla bringing?

About 263 kg of scientific equipment and data are being brought together in the dragon vehicle. These include NASA’s hardware and data related to more than 60 space experiments.
