The U.S. Air Force's top secret X-37B Space Plane made a not-so-secret return to Earth this morning, landing at Vandenberg Air Force Base in California after an impressive 674 days in orbit.
While it's the International Space Station that tends to take all the glory, there is in fact another: China's Tiangong-1, which went into low-Earth orbit in 2011. In this amazing pictures, you can see it silhouetted against the Sun.
China has successfully launched the Tiangong-1, its first space lab. It's the first of a series of small test stations, and the first step towards the country's goal of having a 60-ton space station in orbit by 2020.
China is close to launching its own space station. They are preparing the first module, called Tiangong-1 ("heavenly palace"). It will be first of many and it will launch later this year.
