At 5:42 on November 30, 2022, the Shenzhou 15 manned spacecraft successfully rendezvous and docked with the space station assembly, thus forming a "three cabin and three ship" configuration of the Chinese space station, including the Tianhe core module, the Tianwen experimental module, the Mengtian experimental module and the Tianzhou 5 cargo spacecraft, the Shenzhou XIV manned spacecraft and the Shenzhou 15 manned spacecraft. This manned flight mission not only enabled the "Shenzhou XIV" and "Shenzhou XV" to achieve the "cosmic level same frame", but also achieved the first on orbit rotation of astronauts in China's space history. The successful completion of this historical mission is inseparable from the many "magic tools" on the spaceship. They not only play an important role in the successful launch of the spaceship, but also are closely related to the normal work of the spaceship on orbit and the life safety of astronauts. Fast leak detector for cabin door: check whether the cabin door is well sealed. "The cabin door is closed and you can take off the spacesuit." Such simple and clear instructions are actually the warm care of the hatch rapid leak detector for astronauts. Its internal core sensing system can sense the changes of pressure and temperature, judge whether the cabin door is closed well in a short time, complete the detection of the sealing state of the cabin door of the spacecraft, and provide relevant instructions to the astronauts. In the early days, Shenzhou spacecraft judged the tightness of the cabin door by detecting the change of the cabin pressure. This method was accurate and reliable, but the disadvantage was that it took a long time. "It is on this basis that the rapid leak detector for the hatch has been improved to achieve rapid and accurate leak detection for the hatch and docking surface of Shenzhou spaceship, filling the gap in this field in China." Dong Yipeng, a senior engineer in the Mechanical and Electrical Products Business Department of the Fifth Academy of Aerospace Science and Technology Group, said. At present, the rapid leak detector for cabin door has been productized, forming a type spectrum product that includes fixed and portable, rich gas path and data interface, and has broad application prospects in the field of sealing detection of door or cavity with similar environment. Lighting equipment: light up the Shenzhou interstellar exploration road When flying in orbit, the Shenzhou 15 manned spacecraft will periodically pass through the Earth's shadow area. Therefore, it is very important to have stable and efficient lighting in hand with the space station assembly. The cabin lighting equipment (near distance flood lighting) and rendezvous and docking lighting equipment (long distance light transmission lighting) of manned spacecraft developed by Institute 510 of the Fifth Academy of Aerospace Science and Technology Group not only provide astronauts with cabin work and life lighting, but also provide camera assisted lighting for the rendezvous and docking of spacecraft and space station assembly in the shadow area. In order to meet the use requirements of complex and harsh space environment, the Shenzhou 15 cabin lighting equipment and rendezvous and docking lighting equipment all use advanced solid-state lighting sources. According to Yang Jun, senior engineer of the mechanical and electrical products division of the institute, the advantages of this light source are impact resistance, vibration resistance, low power consumption and high stability. However, due to the performance of luminous materials, solid-state lighting is sensitive to ambient temperature. Joystick: a powerful control tool to get rid of the constraints of gravity. During the launch and return of the spaceship, the astronaut's body is firmly bound to the seat. Even if all kinds of equipment are close, it is "beyond reach". How to solve this problem? The joystick developed by the 510 Institute of the Fifth Academy of Aerospace Science and Technology Group can help a lot. "The handle of the joystick is shaped according to the normal grasp state of the astronaut's palm, and the external contour surface is
