What is the maximum time an astronaut can stay in space?

The longest known time an astronaut could stay in space was 366 days, 19 hours and 20 minutes, a record set by two cosmonauts from the former Soviet Union.

It should be basically about four hours, depending on the individual's physical condition, a good body can stay for a long time, and a poor body is relatively short.

Astronauts have been in space for the longest time in a row for nearly a year, and the longest time they have lived for more than two years, and they continue to push the limits of human beings.

At present, I have stayed for a maximum of 803 days, and the length of stay mainly depends on whether the oxygen is enough, and now the technology is becoming more and more developed, and I believe that the time in space will be longer and longer in the future.

The length of time an astronaut can stay in space is not clearly stated. However, the highest record was more than 400 days.

The longest recorded time an astronaut has spent in space is 879 days.

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. The former space station commander returned to Earth on Saturday and landed in central Kazakhstan for his fifth trip to space.

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.

There is no specific time, but on December 21, 1988, Titov and Manarov set a record for 366 days, 19 hours and 20 minutes of space life.

There is no exact time, but some astronauts have been in space for nearly a year for the longest time, and more than 2 years for the longest time!

Astronauts who stay in space for a long time and return to Earth will have all kinds of discomfort, so they have to return to Earth every six months for recovery training.

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.

Most astronauts are riding on the International Space Station.

To stay for 90 days in a row – that's the average time for astronauts to be "rotated" in the current program. Astronauts spend different hours on the space station, with some astronauts spending up to a week, a month, and even a year.

Some come back early for a variety of reasons, while others may stay for a long time, especially when it comes to providing a basis for human exploration of Mars and flying long hours to conduct medical research on the lives and work of astronauts. It is worth mentioning that the longest stay in space was made by Dr. Valerypolyakov, an internist in Russia, who set this record in 1994 with a stay of 438 days (141 2 months) on the space station, and before that, a record of 241 days of flight set in 1988. The longest time an American has lived in space is 188 days, which is also the world record for a female astronaut, and it was set by Dr. Shannonlucid.
