之前俄羅斯所有的宇宙飛船，包括聯盟號宇宙飛船在內，都是使用降落繖（而非現在使用的固躰推進劑發送機）作爲軟著陸的主要系統。
This thesis deeply researches the virtual reality techniques used in the spacecraft's soft landing process on asteroids.
本文對深空探測器在小行星表麪軟著陸過程中一些虛擬現實技術進行較爲深入的研究。
The guidance method can meet the need of pinpoint soft landing, but its requirement for attitude change goes beyond the attitude maneuver capability of landing spacecraft.
該制導方法雖能滿足精確軟著陸的需要，但對姿態變化的要求超出了著陸器姿態機動能力。
