The European Space Agency is throwing its weight behind a design effort for a hypersonic spaceplane, with hopes of getting the ultimate idea airborne (and spaceborne) by 2031. The ESA is putting up funding for the Invictus research program, which wants to realize considered one of the space industry’s most coveted breakthroughs: The flexibility for a spacecraft to launch horizontally off a runway, like a traditional plane, after which land back there multi functional piece. There have been several attempts over the many years to construct a so-called Single Stage to Orbit (SSTO) vehicle, but to date, none have succeeded.
Invictus (Latin for “invincible”) is hoping to unravel the engineering puzzle, which might make spaceflight radically cheaper and simpler than it’s today. This system is headed by Frazer-Nash Consultancy, with support from Spirit AeroSystems, Cranfield University, and a couple of smaller firms. Critically, the project has hired a bunch of staff from Response Engines Ltd, a British company that had been working on spaceplane engines for many years before going bankrupt last yr. Response’s core innovation was pre-cooling technology, which it at all times said was the important thing to unlocking hypersonic and orbital travel. While the corporate itself didn’t live long enough to seek out out, with the ESA’s money, Invictus goes to try to seek out out needless to say.
Pre-cooling air before it hits the engine
Going to space is pricey. You would like an enormous rocket that launches vertically, which requires a launch pad and launch tower. Rockets are often multi-stage, and most (if not all) of those stages are discarded throughout the flight. SpaceX is developing ways to make those stages fly home for later reuse, however it’s still a massively complex endeavor.
Spaceplanes are a much simpler and theoretically cheaper idea — just take off and land like a plane! — however the trick is constructing cost-effective engines that may power each air and space flight. Extraordinary jet engines need oxygen to burn, which they pull out of the air. But to succeed in the speeds needed to interrupt orbit, hypersonic speeds of Mach 5+, the sheer heat of air friction hitting the engine would actually melt it. Pretty bad!
Response’s purpose in life was kind of to work out a option to get the air temperature down before it hit the engine, a process called pre-cooling. With that system installed, even traditional jet engines should, theoretically, give you the option to succeed in speeds over 15,000 mph, enough to get anywhere on the planet in only a couple of hours. Then, if the craft goes up past the atmosphere and into space, the engines would switch over to onboard oxygen tanks. If all of it works, it should give you the option to ferry cargo to space for radically lower than current systems and to other places on Earth at much faster speed.
The spaceplane race
The ESA, it must be clear, is simply putting €7 million of its money into Invictus, which won’t exactly construct a working plane. This investment is to see if the Invictus team can provide you with a workable design inside 12 months. If not, well, game once again. In the event that they can, nevertheless, then humanity has an exciting future ahead of it.
Meanwhile, there are a lot of other projects around the globe attempting to get their very own spaceplanes off the bottom. Startup company Sierra Space has been working on its Dream Chaser design since 2015, which is getting near having the ability to fly to the ISS. China has flown the Shenlong a couple of times since 2023. The U.S. Space Force has been flying the remotely operated X-37B since 2010, a program that just got a $1 billion from the Big Beautiful Bill. All of those are experimental and never in any form of energetic use just yet. If any of them prepare for showtime, then the times of the huge rocket on a launchpad could also be numbered.
