How long can an astronaut stay in space?

Launched on June 16, 2012, it will carry three astronauts, including the first female astronaut, and is expected to stay in space for 10-20 days.

There is no maximum, and the length of stay is related to the amount of food, water, oxygen.

The longest cosmonaut in space was Sergei Krikalev, a former Soviet Union.

Cosmonaut. He has flown six times on space missions with the Soyuz spacecraft and the U.S. Space Shuttle, and is the record holder for the longest time in space (803 days, 9 hours, 39 minutes).

Astronauts who have been in space for the longest time.

For his outstanding achievements in the field of astronautics, Sergei Kryka Zhenglianlyov was awarded the Hero of the Soviet Union.

and the title of Hero of the Russian Federation.

On December 4, 1998, Krikalev flew into space on the space shuttle Endeavour to start the International Space Station.

The first assembly task.

In February 2007, Krikalev was appointed Vice President of the Korolev Energy Rocket and Space Corporation, and also served as a liquid-starved Gagarin.

Director of the Astronaut Training Center.

Most of the astronauts are inInternational Space StationTo stay for 90 days in a row – that's the average time for astronauts to be "rotated" in the current program. Some people come back early for a variety of reasons, while others may stay for a long time.

Astronauts, in particular, refer to China's stupid spacecraft.

Personnel who enter space flight are also called astronauts outside the country. There are two types of astronauts, professional and non-professional, generally divided into pilots, mission specialists and payload specialists, or commanders, pilots, shipboard engineers and flight engineers. Recently there have been tourist astronauts for tourist purposes.

Astronauts are pioneers in opening up the road to space, and as an astronaut, they need to have high dedication, profound knowledge, extraordinary work ability, excellent environmental endurance, and good psychological quality.

and healthy physical condition.

At 9:22 Beijing time on June 17, 2021, Shenzhou 12 was carried.

The manned spacecraft Long March-2F Yao-12 carrier rocket at the Jiuquan Satellite Launch Center.

Ignition launch. After that, the Shenzhou-12 manned spacecraft successfully separated from the rocket and entered the predetermined orbit, successfully defeating Nie Haisheng.

Three astronauts, Liu Boming and Tang Hongbo, were sent into space, and the flight crew was in good condition, and the launch was a successful completion of the round base.

At the age of 60, a Russian cosmonaut named Gennady Padalka has spent a total of 879 days in space in his 17-year career as an astronaut, making him the longest person in space.

And his previous record holder was also a Russian cosmonaut named Segkrikalev, who spent 803 days in space. Padalka also intends to challenge plans to spend a total of 1,000 days in space.

Astronaut Scott Kelly from NASA is the world's longest-running person working and living in space, spending 340 consecutive days in space to complete NASA's "Longest Space Program."

An astronaut, or astronaut, or astronaut, or astronaut, is a person who has made a career out of space flight or has flown in space. The criteria for determining space flight are not fully harmonized.

In the United States, people who travel more than 80 kilometers (50 miles) above sea level are called astronauts. The International Federation of Aeronautics (FAI) defines space flight as more than 100 km. As of April 18, 2004, a total of 440 people had spent a total of 27,082 crew-days in space, as defined by the United States, and 98 crew-days were shared by walking in space.

According to historical records, the longest recorded time an astronaut has spent in space was in 1999, when Russian cosmonaut Sergei Avdeyev spent a year in the microgravity environment of the Russian space station Mir. The record holder for the longest time was cosmonaut Valery Polyakov, who spent 437 days on the Mir space station from 1994 to 1995.

The 57-year-old Russian cosmonaut Gennady Padalka, who returned to Earth from the International Space Station on his most recent mission, has spent 879 days in space, breaking the previous record of 803 days set by Russian cosmonaut Sergei Krikalev in 2005.

What is the record for the longest time an astronaut has lived in space? This may be the longest, and at this time, it may be a few days.

8 hours.

The extravehicular spacesuit used to carry out the mission is about 2 meters tall, and it is more high-tech than before, with more flexible joints and longer support for the exit time - from the previous 4 hours to 8 hours. The spacesuit helmet is equipped with a video camera, which can record the astronaut's extravehicular operation process throughout the process.

Comparing the ** picture, it can be found that there is a significant difference from the Shenzhou 7 astronauts who went out of the capsule 13 years ago - this time, there is no longer an electric umbilical cord connection between the astronauts and the capsule. This is because the spacesuit has achieved oxygen supply, temperature and pressure control, which reduces the burden of astronauts' extravehicular activities and makes their range of activities wider and more flexible.

Astronauts in extravehicular spacesuits can also use the WiFi in the core module when exiting the capsule. On the second day after the astronauts were stationed in the nuclear roll-carrying module, they had already established a WiFi environment on the module. According to Tang Yi, the overall deputy chief designer of the space station system of the Fifth Academy of Aerospace Science and Technology Group, with the space station as the center, the periphery within a radius of 40 meters can share the "Tianhe" network.

Therefore, the extravehicular astronaut's best picture, voice call, physiological parameters and other data can be transmitted to the cabin and the ground in real time, and reduce the cumbersome wired equipment, making the astronaut's activities more flexible.

Hour by hour.

The time for astronauts to go into space is not the same as that of Earth, because space has no concept of time. The astronauts are timed in the air based on the time on Earth.

Once an astronaut goes into space, if you use the local time as a benchmark, it is still the same because there is no time in the universe, so when we start counting time, we still use Earth time as the standard. The universe is different from the Earth. On Earth, the day is set to 24 hours according to the rotation between the sun and the moon, and day and night are distinguished by this, but after entering the universe, there will be no such concept anymore.

The same. Because the speed of the astronaut's movement after entering space is synchronized with the Earth, the time is the same.
