1. Preparation materials: according to the design and requirements of the work, prepare the required materials, such as paper, glue, scissors, markers, etc. Design works: design sketches or models of works according to themes and requirements. It can be designed by painting, manual or computer-aided design.

2. Cutting and folding: according to the design, cut paper or other materials into the required shape and size with scissors and fold them. Stick and fix: stick all parts together and fix them by other fixing methods. Use colored pencils, pigments or other decorative methods to decorate and improve the works to make them more artistic and attractive.

3. Signature and numbering: Sign and number the work to prove its authenticity and uniqueness. Because of the particularity of space environment, astronauts need to consider the materials, sizes and weights of handmade works to ensure that they can be transported and displayed safely.

In the process of mission implementation, astronauts need to cooperate closely with other members to complete various tasks as planned, including driving spacecraft, conducting scientific experiments and maintaining equipment.

2. Scientific experiments and observation: astronauts carry out various scientific experiments and observation tasks in space, including observing and studying the background of the earth, the sun and the universe, conducting experiments in the fields of physics, chemistry and biology, and obtaining more space and cosmic information. The work of astronauts is very complicated and diverse, which requires a high degree of professional knowledge and skills.

3. Medical monitoring and experiments: Astronauts need to carry out various medical monitoring and experiments in space, including physical condition monitoring, physiological index measurement and drug use. These medical monitoring and experiments are helpful to understand the adaptability and reaction of human body in space environment and provide more medical basis for future space exploration.
