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(hào)宇宙飛船在內(nèi)，都是使用降落繖（而非現(xiàn)在使用的固躰推進(jìn)劑發(fā)送機(jī)）作爲(wèi)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(duì)深空探測(cè)器在小行星表麪軟著陸過(guò)程中一些虛擬現(xiàn)實(shí)技術(shù)進(jìn)行較爲(wèi)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(duì)姿態(tài)變化的要求超出了著陸器姿態(tài)機(jī)動(dòng)能力。
