The European Space Agency’s Intermediate eXperimental Vehicle (IXV) is an interesting platform, ostensibly sharing some inspiration from the United States Air Force’s X-37B but with a very different purpose in mind. The IXV is set to be more of a general purpose craft, one that’s capable of testing new space technologies and running experiments that might not otherwise be feasible. It’s also set to be ESA’s first fully automated craft that’s capable of re-entry, an incredible technological feat that will inevitably find its way into other craft around the world. Today marks the completion of the IXV’s maiden flight, completing a sub-orbital journey that was, by all accounts, wildly successful.
This flight was meant to be conducted towards the end of last year but was delayed due to the novel launch profile that the IXV flight required, something which the launch system wasn’t typically used for. The mission profile remained the same however, serving as a shakedown of all the key systems as well as providing a wealth of flight data around how all the systems functioned during the flight. This included things such as the automated guidance system, avionics and the thermal shielding that coats the bottom of the craft. The total flight time was approximately 100 minutes with the craft making a parachute assisted landing in the Pacific Ocean where it was retrieved by a recovery craft (pictured above).
Whilst the IXV platform is likely to see many more launches in the future it’s actually a stepping stone between a previous craft, the Atmospheric Reentry Demonstrator (ARD), and a future space plane called the Program for Reusable In-orbit Demonstrator in Europe (PRIDE). The ultimate goal of this program is to develop a fully reusable craft that the ESA can use for its missions in space and judging by the design of the IXV it’s a safe bet that it will likely end up looking something like the Space Shuttle. The IXV will never take human passengers to orbit, it’s simply too small to accomplish that feat, however much of the technology used to create it could be easily repurposed to a man rated craft.
I think the ESA has the right approach when it comes to developing these craft, opting for smaller, purpose built craft rather than a jack-of-all trades type which, as we’ve seen in the past, often results in complexity and cost. The total cost of the IXV craft (excluding the launcher) came out to a total of $170 million which is actually cheaper than the X-37B by a small margin. It will be interesting to see if the ESA gets as much use out of their IXV though as whilst it’s a reusable craft I haven’t heard talk of any further flights being planned anytime soon.
It’s great to see multiple nations pursuing novel ways of travelling to and from space as the increasing number of options means that there’s more and more opportunities for us to do work out there in the infinite void. The IXV might not become the iconic craft that it emulates but it will hopefully be the platform that enables the ESA to extend their capabilities far beyond their current station. The next few years are going to be ones of envelope pushing for the ESA and I, for one, am excited to see what they can accomplish.
