PolyU-made space tool sets for inter-planetary mission
A Russian spacecraft carrying the state-of-the-art space tool made by The Hong Kong Polytechnic University (PolyU) embarked on a one-year space journey to the Red Planet at the Baikonur Cosmodrome in Kazakhstan in November. This historical mission, also known as the “Phobos-Grunt” (which means soil of Phobos, the largest moon of Mars), marks the first strategic interplanetary collaboration between China and Russia. This is also the first interplanetary mission of Russia after the dissolution of the former Soviet Union. PolyU has been entrusted with the responsibility of designing a mission-critical space tool known as the “Soil Preparation System” (SOPSYS) for the Sino-Russian Mars Mission. Of interest to the scientific community will be the mission’s first bold attempt in the history of mankind to land on the Martian moon Phobos and collect soil sample for in-situ analysis. If the mission goes as planned, the spacecraft carrying both PolyU-made space tool and Chinese satellite Yinghuo-1 will go near the Red Planet in November 2012. The explorer will then release Yinghuo-1 into orbit around Mars; and seek to release the Lander carrying PolyU-made SOPSYS onto the surface of the potato-shaped Martian moon Phobos. SOPSYS weighs merely 400 grams and measures slightly larger than a cigarette pack. It is capable of grinding and sifting Phobos rock to the size of less than 1mm in diameter and then from it into a plug of measured size for in situ analysis. This procedure is considered a crucial step in understanding the evolution of the universe and the formation of the planet Mars. PolyU researchers have been working closely with IKI (Space Research Institute of the Russian Academy of Science) and the Russian aerospace company NPO Lavochkin in testing the functionality of SOPSYS under extreme environment.
