Why can't Ai Lisha come back?

In order to migrate to Mars, Ai Lisha will live alone on Mars for a period of time, and complete all the tasks assigned to her by NASA before leaving, waiting for the instructions to return to Earth on Mars. However, there are too many unknowns about life on Mars.

It is very likely that Ai Lisha will not be able to return to Earth in the end, which is the most tragic ending of her trip to Mars. Of course, for Ai Lisha herself, she has already prepared herself psychologically.

Ai Lisha:

Ai Lisha, a girl of 13 years old in Louisiana, made a plan 20 years later, that is to become the first "Martian" from the earth. Ai Lisha is currently on the shortlist of NASA.

Ai Lisha said that she has been training in space for nine years, which means that she has been training in space since she was four years old, so she can adapt to weightlessness and be locked in a small space capsule. Now Ai Lisha continues to receive special training organized by NASA.

Ai Lisha said that she hopes to complete the mission of landing on Mars in 2033. She is studying math, science, Chinese and English at present. But this trip to Mars is likely to make Ai Lisha a Martian forever and never return to Earth. Her father said that she had discussed the problem with Ai Lisha, but Ai Lisha insisted on going to Mars.

According to the British Metropolis Daily, NASA is planning to train a group of "astronauts" to be sent to Mars for exploration in the future.
