Astronomer photographs secretive space plane on classified mission
Noted astronomer and satellite expert Ralf Vandebergh of Nijswiller, Limburg, Netherlands, spent months searching the skies for one of the Holy Grails of sky spotting, the secretive U.S. Air Force Boeing X-37B Orbital Test Vehicle. In May 2019, he finally succeeded.
Remarkably, on June 30 and July 2, 2019, that Vandebergh finally captured some rare photos of the secret military spacecraft. Fifty-year veteran space journalist and author of the new book, "Moon Rush: The New Space Race", Leonard David broke the story about Vandebergh's sighting and photos on Saturday, July 6, 2019 on LiveScience.com. The photos are now being republished and shared around the world.

Journalist Leonard David quoted astronomer Ralf Vandebergh in his story on LiveScience.com as saying, "When I tried to observe it again [in] mid-June, it didn't meet the predicted time and path." Vandebergh went on to tell Leonard David in his article that, "It turned out to have maneuvered to another orbit. Thanks to the amateur satellite observers' network, it was rapidly found in orbit again, and I was able to take some images on June 30 and July 2."
The Air Force's X-37B began as a test project with NASA in 1999 but was acquired by the U.S. Department of Defense in 2004. Most sources list two operational X-37B spacecraft and a single X-37A. The fact that only three exist, their missions and roles are classified and they operate in space makes them incredibly difficult to get photos of, especially when performing an active mission as in Vandebergh's photos.
Even more remarkably, according to Vandebergh's photo analysis, he may have actually captured the X-37B with its cargo bay door open, performing some type of experiment or operation.
Vandebergh told reporters, "It is really a small object, even at only 300 kilometers [186 miles] altitude, so don't expect the detail level of ground-based images of the real space shuttle. We can recognize a bit of the nose, payload bay and tail of this mini-shuttle, with even a sign of some smaller detail."
Vandebergh used a 10-inch F/4,8 aperture Newtonian telescope fitted with an Astrolumina ALccd 5L-11 mono CMOS camera to capture his photos. He tracked his elusive quarry across the sky by hand using a small 6×30 spotting scope to line up his telescope for the photos.

Little is known about the current role of the two X-37Bs and the single X-37A. Most likely the X-37Bs are in some form of "operational test" use with the USAF while the X-37A reportedly remains a combined Defense Advanced Research Projects Agency (DARPA) and NASA spacecraft with an equally secretive role.
While most information in the public domain lists both the X-37B and X-37A as "test" vehicles, the X-37B has performed unusually long duration space flights for testing. Remarkably, the current mission being performed by the X-37B in Vandebergh's photos is designated "Mission OTV-5". This mission began 670 days ago on September 7, 2017 when it was boosted into orbit on the SpaceX Falcon 9 orbital delivery spacecraft that launched from the NASA facility at Kennedy Space Center in Florida.
While little is known about the actual mission of this current X-37B flight, author Leonard David may provide some insights in his report for LiveScience.com where he wrote:
"X-37B missions are carried out under the auspices of the Air Force Rapid Capabilities Office, and mission control for OTV flights is handled by the 3rd Space Experimentation Squadron at Schriever Air Force Base in Colorado. This squadron oversees operations of the X-37B and is tagged as the Air Force Space Command's premier organization for space-based demonstrations, pathfinders and experiment testing, gathering information on objects high above Earth and carrying out other intelligence-gathering duties."
