The distance from Earth to the International Space Station (ISS) is only 400 km but Shubhanshu Shukla’s spacecraft dragon will have to travel about 28.5 to 29 hours to cover this distance. So you must be wondering why it will take 29 hours to decide the 400 km journey. The answer is that this spacecraft will require a lot of speed and energy to avoid the gravity of the Earth and enter the right orbit as well as docking of spacecraft with ISS is a very accurate and complex process in which any mistake made can be dangerous. Therefore, the spacecraft must gradually get closer to the ISS, so that safe docking is ensured.

The AXIOM-4 mission on Wednesday, June 25 at 12.01 pm Indian at 12.01 pm Indian time has left for Spacex’s Falcon 9 Rocket Space with 4 crew members from Complex 39A, launched from Complex 39A in Florida, which will reach the space space station after 28 to 29 hours of flight. The launch of the rocket from the Kennedy Space Center in Florida was completely successful. But do you know why it will take about 28 hours for Shubhanshu Shukla to reach ISS in this journey?

Why will it take more than 28 hours to reach ISS?
- First of all, let’s know about the space station located in space, it is located at an altitude of about 400 km from the Earth. It revolves around the earth at a speed of 27,800 kmph. That is, the space station makes a round of the earth every 90 minutes.
- Any spacecraft has to travel at a very fast pace to beat the earth’s gravity and enter the classroom.
- The spacecraft has to accurately prepare to enter the right class, which takes time and energy. After the projection, the spacecraft has to remain on its way using guidance systems, which are complex processes.
- To ensure safety of astronauts and equipment, the journey has to be carefully carried out in a planned manner.
- The time taken for traveling different types of spacecraft (eg soyuz, dragon) vary, some may take up to 6 hours, while others more than 3 hours and some even for several hours.
- It takes several hours due to the speed, guidance, and safety requirements required to travel in space.

These challenges have to face
The spacecraft may face a variety of challenges in reaching the space station, including the problems of spacecraft, navigation problems, and health problems of spacecraft.
Spacecraft
- During the launch or on the way, the system of the spacecraft may cause malfunction, such as engine malfunction, fuel leak, or problem in the communication system.
- Accurate navigation is required to reach the space station. If the spacecraft is not in the right direction or is unable to control its speed, it can miss the space station.
- Space can adversely affect the health of astronauts due to microgravity (low gravity). This can cause muscle and bone weakness, and may cause problems such as dizziness or vomiting.
- Space has a high level of radiation, which can be harmful to astronauts and spacecraft.
- Space also contains small debris pieces, which rotate at a very fast speed. These debris pieces can cause damage by hitting a spacecraft or space station.
- Despite all these challenges, scientists and engineers are working continuously to reduce these problems and safely transport the astronauts to the space station.

Why is a dragon spacecraft special?
- The spacecraft carrying four people including Shubhanshu Shukla into space is very special. According to Spacex’s site, the Dragon spacecraft has completed a total of 51 missions so far and has now flew for its 52nd mission. Earlier, 46 times this has gone to international space station and 31 times it has traveled to space again after returning to Earth.
- The Dragon spacecraft is capable of taking 7 astronauts at a time to the Earth’s orbit or beyond and its most important thing is that it not only goes to space but it also comes back and can also be used again.
- The dragon has Drako thrusters and these thrusters also allow the dragon to change their direction while living in an orbit. Along with this, it has 8 superdrecoses that strengthen the launch escape system of the spacecraft.
- Its height is 8.1 meters, it is 4 meters wide, while launching its payload weighs 6000 kg, while when returning to the earth, it becomes half weight i.e. 3000 kg payload.
