Reaction Engines Goes Into Bankruptcy, Taking the Hypersonic SABRE Engine With it

Scale model. Skylon is a British design for an unmanned Single Stage to Orbit (SSTO) spaceplane designed to reach Earth orbit where it would deploy and retrieve satellites. It was intended to be completely reusable, with the objective of cutting the cost of launches dramatically. It was envisaged that some 30 Skylon vehicles would be built, and operated by commercial companies, and it was planned that Skylon could be adapted for carrying passengers, or ‘space tourists’. At the heart of the Skylon concept were its two innovatory Synergestic Air Breathing and Rocket Engines (SABREs) which were designed to draw oxygen directly from the atmosphere. Skylon is one example of several SSTO launcher concepts considered worldwide in the 1990s.

Rarely does something get developed which is a real game changer in space exploration. One example is the Skylon reusable single-stage-to-orbit spaceplane. Powered by the hypersonic SABRE engine it operates like a jet engine at low altitude and more like a conventional rocket at high altitude. Sadly, ‘Reaction Engines’ the company that designs the engines has filed for bankruptcy.

Shhh, NASA Reveals its New Quiet Supersonic Aircraft

NASA’s X-59 quiet supersonic research aircraft sits on the apron outside Lockheed Martin’s Skunk Works facility at dawn in Palmdale, California. The X-59 is the centerpiece of NASA’s Quesst mission, which seeks to address one of the primary challenges to supersonic flight over land by making sonic booms quieter. Lockheed Martin Skunk Works

The term space plane conjurs up all sorts of images and NASA, with their new X-59 (even the name sounds mysterious) they have definitely not dissapointed. Their new quiet supersonic aircraft has been designed to minimise the sonic boom it creates when it crosses the speed of sound. It will fly at 1.4 times the speed of sound and is set for its maiden flight later this year.

A year ago, the high-altitude launch company Stratolaunch flew the world’s largest aircraft. Now, Stratolaunch has revealed the designs of two hypersonic aircraft plus a reusable space plane that will be launched from its giant Carrier Aircraft launch plane. The company hopes to begin test flights of these vehicles by 2022.

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.
