It landed at Vandenberg Air Base in California on October 17 morning local time.

US Air Force officials say the X-37B was born to test advanced technologies for the future generation of " reusable " shuttles in the future.

However, some doubts say it is used to monitor a Chinese space lab that has not been recently appreciated by experts.

According to the BBC, this is the third time the US Air Force has put the X-37B into orbit. The previous two flights of X-37B were in April 2010 (returning after 8 months) and in March 2011 (returning after 15 months).

The fourth X-37B flight is expected to take place next year from Cape Canaveral, Florida.
