Mission: Tenacity | Dream Chaser Propulsion Systems

We are committed to developing and implementing innovative and low-cost, in-space, upper stage, and boost propulsion systems.

We provide patented rocket propulsion technologies, state-of-the-art testing and analysis services, and decades of experience in the use of planetary resources for civil space, commercial space, and military operations.

Our propulsion team has designed, manufactured, and tested multiple thrust chamber assemblies in the 1 lbf to 35,000 lbf thrust class range with a variety of propellant combinations, such as Peroxide/RP1, LOX/kerosene, LOX/propane, LOX/Hydrogen and N2O/propane.

What an amazing video to showcase the efforts of your engineering and product development teams!

After seeing many space projects get funded and cancelled over the decades I highly respect Sierra Space for continuing their Dream Chaser vision. "Tenacity" is a great name!

When Ben Riggles was introduced I had to rewind and pause the video to make sure I read "Badger Test Manager" correctly. I thought for sure it was badge test manager and my brain was having a Monday.... Nope, dude really is a badger tester and I now have a new career aspiration.

I realise this video was probably NOT a result of my previous comment about more frequent content, but this was exactly what I asked for, so... thank you.
More please :)

Love the narrator's voice, it's so retro-cool. Classic feel to it, couldn't be better. excellent.

YT algorithm brought me here! Finally! The Chaser look is so sci-fi. Brilliant to see the details for the rocket engine.
More video updates please.

My mother was an outgoing inspector for Sperry ad the space shuttle avionics, so your program has a special place in my heart. I can’t wait to see how the next decades takes your amazing work and takes it from one of prototyping to masproduction.

4:36 The Vortex combustion chamber is revolutionary... That wasn't lost on me! ;)
Sounds like a very clever design, well done!

I have been looking forward to this since the 90's. This design is descendant of many models of lifting bodies that have been tested by many different companies and agencies. That new RCS tech is really exciting. And it only gets better from here.

Looking forward to Dream Chaser flying!

It's inspiring to see such a young group of Can-Do Engineers working on this!
I believe the average age of Apollo Engineers and Techs was under 35 years old and look what they did!
I can't wait to see Dream Chaser fly!
Returning to Earth in a Dream Chaser will be a lot safer and more practical than in a Starship!

[DavidGalich]

That much be such a rad gig...launching into a new era of space exploration. Good to be alive.

[DigDougDig]

Looking forward to seeing the Dream Chaser fly.

[swapshots]

I've been waiting anxiously for a long time to see this become a routine flyer.

[jerryarcher]

Great job, you guys seem to be very excited about what you all have developed. Being a retired controls engineer, I never stop learning new things. Can’t wait to see Dream Chaser in action.

[MrFranklitalien]

looking forward to see it take off atop the vulcan centaur early next year hopefuly :) keep it up you guys, all your hard work will soon pay off

[Xerethane]

Dream Chaser is the dark horse I've been hoping to see for years now. I'm really looking forward to seeing you launch!

[Nick-uwtx]

Awesome! Keep up the great work. All eyes will be on you when Dram Chaser flies. Can't wait!

[jimcabezola]

Looking forward to Tenacity's first flight!

[plasticmug]

That was actually quite good exciting production good engineering advert, keep up the good work
