NASA’s long term orbital drone, the X-37B Orbital Test Vehicle, made an unannounced (at least to the public) landing at NASA’s Kennedy Space Center Shuttle Landing Facility on Saturday.  The unmanned spacecraft that bears a striking resemblance to the now defunct space shuttle, first made its presence known to the community surrounding Kennedy Space Center on Saturday morning as it broke the sound barrier during re-entry, prompting a number of Tweets directed at NASA attempting to determine where, or what, the boom may have come from.

The ship has been in orbit around the earth for a whopping 718 days during this mission, bringing the total number of days the X-37B orbiter program has spent in space up to 2,085 days.

“Today marks an incredibly exciting day for the 45th Space Wing as we continue to break barriers,” said Brig. Gen. Wayne Monteith, the 45th SW commander in a press release. “Our team has been preparing for this event for several years, and I am extremely proud to see our hard work and dedication culminate in today’s safe and successful landing of the X-37B.”
