Skywatcher and Satellite Tracker Photographs US Air Force’s Secret Space Plane in Orbit!

Ever since it started taking to space, there has been a lot of mystery and controversy surrounding the USAF’s X-37B space plane. Despite the fact that this militarized-version of NASA’s orbital vehicle has conducted several spaceflights since its first in 2010, we still have no idea what its true purpose is. But so far, the smart money appears to be on it being an advanced spy plane.

Hoping to gather clues to this question, skywatcher and satellite tracker Ralf Vandebergh of the Netherlands has spent the past few months hunting for this space plane in the night sky. Recently, he was fortunate enough to not only locate the elusive X-37B in the sky but also managed to snap some photographs of it. Given its diminutive size and secretive-nature, this was no small feat!

Progress for the Skylon. Europe agrees to continue working on the air-breathing SABRE engine

When it comes to the future of space exploration, the name of the game is “save money”. To do this, space agencies and aerospace companies around the world are investing in things like reusable rockets, single-stage-to-orbit (SSTO) rockets, and reusable space planes. This last concept builds on the tradition established by the Space Shuttle and Buran spacecraft, two reusable vehicles designed to make space launches more affordable.

The one drawback of these spacecraft was the fact that it still took two rocket boosters and a huge external fuel tank to put them into orbit. This is where the Synergetic Air Breathing Rocket Engine (SABRE) comes into play. With the help of the European Space Agency (ESA) and the UK Space Agency (UKSA), this revolutionary hypersonic engine recently took a big step towards fruition.
