ESA: Full-sized model of its Space Rider reusable capsule is ready for landing drop tests

My heart be still! The European Space Agency (ESA) yesterday announced that a full-sized model of its Space Rider reusable capsule is now ready for landing drop tests from a helicopter.
The avionics – Space Rider’s ‘brain’ – were installed in the second week of March. This computer hosts the Guidance, Navigation and Control algorithms that will steer the parafoil, adapting to the wind – including any gusts– to guide Space Rider to a soft landing.
Roughly the size of a mini-van, the drop-test model is a full-size stand-in for the 4.6-m long reentry module, Space Rider lands on skis with the landing gear permanently open on this model as the mechanism is not part of the drop test.
To get an idea how unserious ESA is, we need to review this project’s overall schedule. This reusable capsule concept — which appears to be a variation of either Varda’s returnable capsule or Boeing’s X-37B — was first tested by ESA in 2015. By 2017 the agency was promising it would be flying commercially by 2025. A decade later and they have not yet begun testing a full scale spacecraft.
And the development pace now is glacial. Last summer ESA did helicopter drop tests of just the “brain” and parafoil. It is now going to do those drop tests again, a year later, with this full scale model. Expect another year to pass — at a minimum — before it tries another set of helicopter drop tests, this time with the first actual Space Rider capsule.
At this pace, Space Rider might fly by 2030, maybe. In the meantime, expect at least a half dozen private capsules to fly commercially, for profit. Following Varda’s success investment capital has poured into this industry. All will go from a blank sheet of paper to a flight model in less than five years.
And even if ESA finally gets Space Rider operational, it has established some very complex rules about who can use it commercially, rules so complex I predict few will be interested.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Too bad this is in the EU.
Space Rider is a pretty cool name.
Well, it’s a pretty ship, and a pretty render. So there’s that.
This thing is a lot bigger than Varda’s capsules but will also be a lot more expensive to launch. Varda buys space on SpaceX’s Transporter rideshare missions to put its capsules up.
Unlike Varda’s capsules, Space Rider is intended to be reusable as is the X-37B. The X-37B is much larger than Space Rider but is also entirely unavailable for commercial purposes. I think Space Rider’s main competition is likely to be the Exploration Company’s reusable Nyx capsule. Or maybe I should restate that the other way around as Nyx seems likely to fly sooner than Space Rider.
