JP Aerospace updates

Do not know if this really belongs there, but they are somewhat regularly flying to the edge of space.

They just posted this

Saturday Tandem soared to 95,085 feet.  She flew perfect. We fired up the propellers and drove her around then softly touched down three hours later.

Gorgeous pics !

Oh, and this is definitely "Commercial", as shown by the spectacular Samsung Mobile space balloon project they did.

Call in with your questions.
Jeff Bezos has billions to spend on rockets and can go at whatever pace he likes! Wow! What pace is he going at? The slowest possible.

That's tomorrow. I expect a good review of what they've been up to in the last 2 years and some hints of what's next.

It's an hour before the interview. Any questions anyone has before it starts?

I'd love to hear how the Samsung Galaxy project came about.

Samsung has seen our work on the Toshiba Chair project. We got the call and pretty intensely worked for it.  It just won the Media Arts Festival's Grand prize in Tokyo. I just got back yesterday and am still a little jet lagged.

Great show. People living in the sky is a concept that really sizzles.

I've always thought that the idea was very cool. Balloon to the top of the atmosphere. Transfer to another craft that would use an ion drive to orbit. That could be a crazy reduction in surface to LEO costs.

I don't know how close we are to materials that would support large, long-lived balloon structures in space and near space.

95,000 feet?
That can be considered the boundary region near space.
Air density and pressure at those altitudes are comparable to a
good highschool vacuum belljar.

JP Aerospace reached a significant milestone on Sunday:

Quote
Ascender 26 Flies!

Sunday June 14th our 26 foot Ascender airship took to the sky in Northern Nevada. This vehicle is smaller than some of our other vehicles, but it is extremely important. It is a test bed for an entire new internal structure and new internal helium cell interface.  It was intended to be a short hop to 1000 feet above the ground. However everything was going so well we let her run and flew to 2585 feet above the ground (6,708 feet above sea level). We had the combination inner cell fill volumes and balance off by about six ounces and we floated tail up about twenty degrees most of the way. It slowed the climb rate a bit but didnít detract from an excellent flight.

The Ascender is a pretty complex system with four helium inner cells, servo control vents, an outer envelope pressurization system, a carbon truss internal structure, full unlink command and tracking system and independent backup gas release systems.  The real value of this test flight was learning to deploy this complex of a system in the field. We still have goose bumps on how great the flight went. This is the vehicle that paves the way for the next generation of Ascenders to come.

I believe they are now past the half-way point in their airship to orbit programme. It may not seem like it because so much of what they are doing is technology development (eg MHD generators) but with Ascender 26 now flying things feel a bit more concrete now.

There's no way they're past the halfway point to orbit.  They don't even have a credible plan to get to orbit.

They've only done things so far that everyone always believed were doable.  They've never shown the slightest bit of evidence, or theory, for how they can do the part that most people who understand basic physics think they can't do: accelerating to orbital speed with a low-thrust engine.

Lift and drag scale together.  If they are in a part of the atmosphere where they are getting enough lift to significantly offset gravity, they will have significant drag.  And drag scales horribly with speed.  To get to orbital speed, they would need lift-to-drag that is orders of magnitude better than anything anyone knows.

I'd say it a different way: if JP knows how to get this thing to orbit, he's not telling us :)

Last time I heard anyone ask (The Space Show, last year) he was saying he had ideas how to do it, but figured they were probably wrong, but was going to try anyway. i.e., it's a science project, not an engineering project.

Even rudimentary analysis is telling that the thing isn't going anywhere near orbit.

The science here is determining if valiant effort warms the hearts of well known physical laws making them look the other way just this one time.

Having said that the PongSat program for kids is great stuff.

Yes. Absolutely. Still, if he wants to try something new and it:s self-funding. Who cares?
