China’s successful launch of the Shenzhou VII and subsequent spacewalk further reflect how the nation’s space program has risen on the bootstraps of Russian technology. Although the Chinese press has touted the supposedly home-grown Feitian space suit, the mission still relies on Russian advisors, who in addition to technical support provided Russian Orlan space suits. The Long March 2F rocket was also optimized with Russian assistance. The boosters use UDMH/N204 (nitrogen tetroxide) and consist of a two stage core vehicle with four strap-on stages. Four YF5-1 chamber motors with swinging nozzles have 75,500kg of thrust for the first stage. The second stage has a YF20-1 (75,600kg thrust) rocket motor with fixed nozzles and a YG21-1 swiveling venire motor with four chamber motors (4,813kg total thrust). The four strap-on stages are single 75,500kg thrust YF5-1 engines with fixed nozzles. The walk marks the second stage in China’s goal of building a spacelab by 2020. After the spacewalk, Chinese astronauts will attempt capsule docking. In 2010, Shenzhou VIII, IX, and X will be launched in rapid succession of one month intervals. The first two launches will be unmanned, carrying laboratory equipment.
