soft spacecraft landing

基本解釋

All previous Russian spacecraft, including Soyuz, used parachutes as the main system for soft landing.
之前俄羅斯所有的宇宙飛船，包括聯(lián)盟號宇宙飛船在內(nèi)，都是使用降落傘（而非現(xiàn)在使用的固體推進劑發(fā)送機）作為軟著陸的主要系統(tǒng)。
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面軟著陸過程中一些虛擬現(xiàn)實技術(shù)進行較為深入的研究。
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(dǎo)方法雖能滿足精確軟著陸的需要，但對姿態(tài)變化的要求超出了著陸器姿態(tài)機動能力。
