China's experimental space lab Tiangong-2 orbiting the Earth with two astronauts on board has successfully launched a micro-satellite, roughly the size of a desktop printer. <br/><br/>Weighing 47 kilogrammes, the micro satellite has a series of visible light cameras, including a 25 megapixel camera and wide-angle imagers. Its mission is to take photographs of Tiangong II and the Shenzhou 11 spacecraft, which docked with the lab on Wednesday.<br/><br/>The Tiangong II space laboratory released its companion satellite, Banxing-2 yesterday. The satellite, which the media has nicknamed "Selfie Stick", also has an infrared camera that is temperature – sensitive. <br/><br/>With three solar panels, the satellite can also generate enough power to adjust its orbit to shoot pictures of the lab and spacecraft. The Shenzhou-11 spacecraft carried two astronauts into space on the 17th of this month. It docked with Tiangong-2 two days later.
