The construction of the Chinese space station has been officially started. Commercial spaceflight is in full swing. People on earth fly into space more and more frequently. Just as we could not imagine a smart phone 20 years ago, the speed of technological development is often much faster than expected. Maybe 30 years later, ordinary people can travel in space as easily and conveniently as by plane.
However, we can't always think of the good. It's inevitable that people will be delayed when flying. In the more mysterious space, it's inevitable that there will be some accidents when flying on spacecraft. It's very important to make a plan.

Imagine that when you fly to a place of travel in space, you are wearing an extravehicular spacesuit to experience a vacuum, or you are enjoying the vastness of the galaxy in front of the window of the spacecraft on the journey, but you encounter a space "storm" (the space weather forecast will only be more unreliable than the earth), you can't move on time, and the food you bring when you leave is almost finished. What should you do?
In other words, how can we get supplies if we are stranded somewhere in space due to special circumstances?
Many people must blurt out: "grow potatoes!"
Yes, science fiction shows us a lot, which can be divided into two categories.
First, space capsule planting and breeding. In recent years, Chinese spacecraft have carried earth's crop seeds to the sky for many times. With the help of the special space environment, researchers carry out various experiments. Thanks to the "vegetable loving gene" of China's big agricultural country, China has finally built a renewable life insurance system that can be reused, that is, vegetables can be replanted in the space capsule.
Imagine the future. In addition to carrying food products that do not affect the safety of human body and equipment, space tourists will certainly be able to eat fresh leafy vegetables.
Astronauts of the international space station have tasted the space chili corn cake. As the space capsule planting business climbs to a new height, more and more plants are harvested. It is not impossible to breed little sheep in the space capsule. You may have an unexpected blessing in space.

Second, planting and breeding on other planets. Chinese and foreign scientific research teams have successfully cultivated plants by using lunar soil. with the space power generation project providing more and more sufficient energy, considering the chemical and biological technological progress of the earth, it may be very close to the large-scale cultivation of potatoes and other crops in lunar soil**
Astronomers have been trying to find sources of water, soil and oxygen on nearby planets. After all, water and oxygen are important basic materials for life on earth. The scientific research team has found active compounds in lunar soil, which is expected to help synthesize oxygen, hydrogen, methane, methanol and other fuels.
Perhaps in the near future, using the materials from other planets and the "secret recipe for deployment", people on earth can really learn from "astronaut markwatney" to develop a suitable environment and plant fast-growing plants in Mars and other space travel places. Improve the quality of life. If local building conditions permit, it is also possible to breed animals.
Are these ideas wonderful? In fact, the earth people who do this are "diligent and honest people".
There is no shortage of food service areas near airports and highways today. It is likely that 24-hour convenience stores will be opened during future space travel. Supplies will be regularly supplied by spacecraft, and the inventory will be enough for space tourists to consume for a long time.
If the inventory is limited, space tourists can send a signal to the earth or the nearby space city for help. It is believed that China's reusable cargo spacecraft, which was mature at that time, will send supplies as soon as possible. This should be the most reliable way. After all, space tourists are not necessarily experts in growing vegetables.
With the continuous improvement of the reusable capacity of the cargo spacecraft, the comprehensive benefits of China's transportation of space materials will be further improved. It will not be a distant dream to enjoy hot pot, barbecue and crayfish on the space station.
