China's Space Lab Tiangong-2 launches Micro-Satellite Banxing-2
China’s experimental space lab Tiangong-2 orbiting the Earth with two astronauts on board has successfully launched a micro-satellite Banxing-2.
The two astronauts were launched into space onboard of the Shenzhou-11 spacecraft carried two astronauts on 11 October 2016. It docked with Tiangong-2 on 13 October 2016.
- The micro-satellite Banxing-2 is roughly the size of a desktop printer and the media has nicknamed “Selfie Stick”. It weighs 47 kilogrammes.
- It has series of visible light cameras, including a 25 megapixel camera and wide-angle imagers. It also has an infrared camera that is temperature-sensitive.
- Its mission is to take photographs of Tiangong II and the Shenzhou 11 spacecraft, which has been docked with the lab.
- The micro-satellite has three solar panels which generates enough power to adjust its orbit to shoot pictures of the lab and spacecraft.
- its predecessor, Banxing-1, accomplished the same mission for Shenzhou VII in 2008.
- Banxing-2 is new model of its predecessor Banxing-1 which had accomplished the same mission for Shenzhou VII in 2008. However Banxing-1 is smaller and has a higher capacity.
