Coinciding with the country achieving its first ever docking in space between the unmanned Shenzhou 8 spacecraft and Tiangong-1 space lab module, the "China Post Space Office" opened for business both on the ground in Beijing Aerospace City and, at least virtually, on board the newly established orbital complex.
Located on the ground near China's mission control, the Beijing Aerospace Command and Control Center (BACC), the new space post office even has its own zip code that extends into orbit: 901001.
