Recently, astronauts from Shenzhou 18 successfully returned to Earth. After a space journey, astronauts Ye Guangfu, Li Cong, and Li Guangsu safely arrived in Beijing and entered the recovery phase. However, during the return process, the continuous rolling of the return capsule has attracted widespread attention.
It is reported that the return process of Shenzhou 18 adopted a "rapid return" plan, which includes five stages: separation, braking, re-entry, deceleration, and landing buffer. Although this plan has been adopted since Shenzhou-13 and the technology is mature, the rolling phenomenon of the return capsule during the final landing phase still aroused public curiosity.
Experts explain that the state of the spacecraft's return capsule during landing is influenced by various factors, including parachute pull and ground flatness. Rolling phenomenon may be caused by the operation of parachutes in specific environments or ground conditions, and may not necessarily reflect a technological gap.
It is worth noting that not only have China's Shenzhou spacecraft experienced rolling landings, but foreign spacecraft such as Russia's Soyuz series have also experienced similar phenomena. This indicates that in the aerospace field, such phenomena are not isolated cases, but may be caused by various complex factors.
China is actively developing a new generation of manned spacecraft to further improve the safety and comfort of astronauts. The new generation of spacecraft has taken into account the requirement for upright and non-destructive landing in its design, and is equipped with advanced technologies such as buffer airbags to achieve smoother landings in the future.
Overall, the successful return of Shenzhou 18 marks another important milestone in China's aerospace industry. Although there were some noteworthy phenomena during the landing process, it did not affect the success of the entire mission. With the development and progress of the new generation of spacecraft, we have reason to expect that China's aerospace industry will make more breakthroughs and achievements in the future.
