Update 2 October 2011 9.50 am Daylight Savings Australian Eastern Time: The Chinese Space Agency changed the orbit of Tiangong 1 overnight (circularised it). This means that the predictions from the Heavens-Above.com site (linked to below) will be incorrect until its database has been updated. The site is based in Germany and we will need to wait till the owner wakes up for that to happen.
Original post 1 October 2011: Depending on where you live, you will be able to see the new Tiangong 1 Chinese test module pass overhead. The exact viewing times will depend on where you are. From Australia, Tiangong 1 is presently visible in the predawn sky. Instructions on how to generate viewing information for your location can be found here on this website.
(Text from Wikipedia) Tiangong-1 (Chinese: 天宫一号; pinyin: Tiāngōng yīhào; literally “Heavenly Palace 1” or “Sky Palace 1”) is the first Chinese space station, intended as a testbed to develop the rendezvous and docking capabilities needed to support a larger space station complex. It is part of the Tiangong program, also known as Project 921-2, which aims to place a larger, semi-permanently crewed modular station into orbit by 2020. Launched unmanned aboard a Long March 2F/G rocket on September 29, 2011, Tiangong-1 is expected to be visited by three Shenzhou missions: the unmanned Shenzhou 8 in 2011, and the manned Shenzhou 9 and 10 in 2012.
My interpretation of the information available indicates that Tiangong-1 is the forerunner of a robotic space freighter similiar to the Russian Progress spacecraft which are used to automatically refuel the International Space Station.
