Dream Chaser - The Dream Of Lifting Body Space Planes

Thank you for sharing the journey of our Dream Chaser spaceplane. We look forward to the launch of Tenacity!

[@DawnPetrichor1]

Heya, nice to see your organization interacting with the community. I’m just starting to learn about Dream Chaser, I’d previously only vaguely heard about it, but it seems like an interesting concept! I’d previously dismissed it as another project with way-too-high ambitions, but it’s looking good, as far as I can tell, and the mission goals seem pretty solid. To DreamChaser!

This Soviet system is quite unique. It used metal for heat shielding and ceramic joints (hinges of special design) in order to isolate cold volume inside of the ship from hot metal shielding.

Another test pilot who was slated to fly Dyna-Soar was Albert Crews. He still volunteers as a docent at the Sands Space History Center just outside the gates of CCSFS and I highly recommend taking a tour if you ever happen to be in the area. He was also chosen as an astronaut for the MOL program before it too was cancelled. Really fascinating individual to talk to if you happen to run into him at the museum. Honestly, most of the docents have worked at the Cape in some capacity and all have great stories to tell.

I could have talked about pianos instead to make the same point. The shuttle and Buran did generate lift from their fuselage shape.

[@sanchorim8014]

@@Julius_Hardware There's a debate? Buran is clearly based on Shuttle. I still find it funny that the Soviets decided that the American vehicle was so ridiculous that we wouldn't use it unless we knew something they didn't, and decided to copy that.

I really hope Dream Chaser finds lots of success, though really only because of my nostalgia for the shuttle. I grew up on the space coast, and that beautiful black and white bird was plastered on everything. Everyone used to be so proud to even be part of the support structure for the people who made those things fly. I have no control over what systems get used for future spaceflight missions, but I hope they involve lots more tiled lifting bodies.

[@wilboersma9441]

Same! I relate to that so much. The Shuttle gets bashed by so many people so often who can only see the price tag and say that "it's refurbishable, not reusable" which is true, but they just can't appreciate it's affect on people's imaginations and their way of viewing space. Space went from something only highly-trained professional test pilots can do, to something you can literally "hop on a shuttle" nd go to a space station. It will forever be the first true spaceship.

[@keiyakins]

Honestly the biggest problem with the shuttle is the enormous cost and juuust enough refurbishability meant we couldn't really iterate on them.

[@wilboersma9441]

@@keiyakins Yeah, once the shuttle was operational they never got enough funding to make them better, no "Shuttle V2" or an Energya-like launch vehicle. Hopefully Starship can escape the same fate because now private companies are doing the developing in a competitive atmosphere, not a political vacuum (see what I did there).

[@Blaze6108]

Well, while lifting bodies are harder to make than classical rockets, they do have the advantage of being able to land without having to waste 30-40% of their delta-v on retropropulsion. So in the future, when advanced materials and shapes become more practiceable, they might become more commonplace.

[@ronjon7942]

A reply to another comment about using ‘outdated’ tech: ​ That’s a good point. It’s a little sad to hear so many criticize the DC, and fault the Shuttle’s safety record due to it’s design, which just isn’t true. The Challenger o-ring issue and Columbia’s foam issue seem more related to installation and operational problems, poor assumptions…you obviously know the story. But to criticize the Dream Chaser for using tiles and ‘old’ manufacturing techniques that are based on prior NASA and Shuttle evolution and experience is just ignorant of safety and reliability first, over cutting edge and using technology that, while great and seems to be working well, just doesn’t have the maturity of all the DC is using. OK, I’m off my high horse. Actually, I’m a SpaceX fanboy and think they’ve done and are doing phenomenal work; same w RocketLab, Firefly, now Relativity, Orbital, even Astra - hopefully they can get back on track. But no one at NASA is going to risk their careers (and manslaughter charges) by ditching Sierra and going w some 3d printed designs, endangering lives w the latest. Really, I’m surprised NASA went with Dragon so quickly - turned out to be a good call in the end, but whew.

[@snower13]

The large wings on the space shuttle were needed to give the aircraft large amounts of crossrange. That was needed because the military wanted to do one orbit flights, and return to the launch site. Probably to capture USSR satellites. I feel like Scott did a video on this?

Last summer I found myself driving near one of their facilities here in Colorado and I'm excited to see them bring that bird to life.

[@taraswertelecki3786]

Hopefully, they can get Dreamchaser, or a successor to the point where if the need arises, one can be aloft within hours to rescue a crew in trouble aboard ISS or some other space station. The threat to the lives of astronauts from equipment failures or collisions with space junk are very real, and the more people are in space for longer periods of time, the sooner one of more people will die up there without a rescue vehicle on the way to save them.

[@rocketsocks]

I think one of the major benefits of having a space station is being able to run this development cycle for pressurized spacecraft of doing a cargo vehicle of a new design first then doing a crewed vehicle. It's definitely been advantageous for SpaceX's dragon, you can see the design and operational maturity in the crew dragon from the lessons of running the cargo program, and, perhaps, the lack of that maturity in Starliner.

[@whidzee]

The origins of the lifting body concept dates back further than that. Look at Burnelli's designs. He created planes that had fuselages shaped like aerofoils which had amazing performance properties. the last one around exists in the New England Air Museum, called the Burnelli CBY3 - Loadmaster

[@edwinkania5286]

Glad to see the shout out for test pilot Steve Austin. Eventually he got hardware upgrades and became Scott Manley.

[@tomersde]

You forgot to mention the X-38, the closest we got to an operational lifting body craft until now. The prototype was over 90% complete with a reservation on a Shuttle to bring it up to the ISS. It was suppose to be a lifeboat first, but anyone with eyes could see that it was a viable crew transport. With Ariane 5 already man-rated and Atlas 5 coming online in a few short years you'd think that there's no way it wouldn't become operational, but in pre-Columbia days anything that was risk to Shuttle's supply chain ended up going nowhere and so did the X-38

[@Nowhereman10]

No, that last part simply wasn't true at all. The reason it was cancelled was to save money on the ISS program which was suffering from cost overruns. Those cuts also extended to the cancelling of actual full modules for the UOS that were also far along in construction, namely the Habitation and the Centrifuge modules. The second of the two Boeing-built node modules was left grounded in favor of a barter agreement with ESA to have them build additional nodes in exchange for a Shuttle launch of the Columbus module and other hardware.

[@antigravityworkshop1436]

Thanks for mentioning that. The SAC Museum west of Omaha has one of the X-38 test articles. I was explaining to my tour companion the whole life boat for ISS story at a Space Station model. We rounded a corner and - there she was. The X-38! It would have been really cool but the traditional aerospace industry (Boeing, Lockheed, etc.) just can't keep a program on time or on budget. It's a shame. Could have been a great vehicle.

[@Nowhereman10]

@@antigravityworkshop1436 The X-38 orbital vehicle that was nearly complete at the time of cancellation was not being built by LockMart or Boeing, it was being built in-house at Johnson Space Center. Scaled Composites built the shells and some of the hardware for the atmospheric test craft. In the end, X-38 was blanket cancelled along with the Hab, Centrifuge modules, and grounding the Boeing-built Node-2, etc to cover cost overruns in the program.

9:13 This somewhat vindicates Buran and Tu-144 which were always accused of being just copies of the Shuttle and Concorde. The shapes were clearly copied to a large extent, in spite of denials by Russia. But the similarity was only skin deep which not everyone realizes. I'm sure other than the shape, Dream Chaser has little in common with the MiG-105. Although one feature that would be good to copy from the MiG-105 is the jettisonable crew capsule that would have brought the crew down by parachute in case of an abort.

[@Nowhereman10]

Ah, you skipped one of the other important lifting body developments, the X-38 which was to have been the U.S. contribution to the Assured Crew Return capability, in addition to Russia and Roscosmos' Soyuz. It was cancelled in the early 2000s just as first spaceflight capable vehicle was nearing completion in order to save money, and despite a good number of test flights with subsonic flight articles showing the vehicle not only could fly, but it had a rather unique parafoil system that would allow for very gentle and slow touchdowns without the need for large amounts of runway. Unfortunate that happened since the X-38 ARCV was capable of carrying the entire 7 person crew back and it was being built so that it could stay on orbit for years, thus reducing the need for a launch every 6 months as is the case for the current crew vehicles.

[@thomasackerman5399]

Yeah, X-38 ARCV's loss is now coming back to bite NASA and Roscosmos with this latest little incident involving the MS-22 Soyuz, especially with the first flight vehicle about 93% complete!

[@Wordsmiths]

@@thomasackerman5399 Sad and true. They sowed a minimal crew-return policy, and they reaped a crew-return crisis. Again. It's a testament to how well the operational side has been handled that they haven't had more frequent and more serious crew-return crises over the years, honestly. If we're going to make any progress in cislunar space development (involving human crews), we have got to have more options, more "dissimilar redundancy" in crew launch and crew return vehicles. Here's hoping that an X-37B crewed variant (or a resurrected X-38?) will follow the Dream Chaser to offer yet another option with yet another set of capabilities distinct from the other options. (...but first let's get Dream Chaser operational!)

[@kevinrusch3627]

I've always loved the idea of that thing.

[@DeadBaron]

I remember learning about Dreamchaser years ago and thought it was a dead project, I'm glad to see it's still around

[@odysseusrex5908]

Sierra had bid Dream Chaser for the Commercial crew contract. They were a finalist but lost out to SpaceX and Boeing. Boy, I bet somebody at NASA wishes they had picked Dream Chaser over Starliner. Anyway, after that, on their own dime, they modified the design to an unmanned one and bid on the resupply contract which they won a piece of. They are still, on their own dime, developing a new manned variant. Sierra doesn't let anything hold them back.

Oh man, the clips at 5:35 bring back memories! I had that VHS growing up and wore it out…. Great stuff!!

[@sadham2668]

Do you remember what is was called?

[@ryanhamstra49]

“Space shuttle in the beginning” It’s part of a 5 cassette set, which I have recorded and plan to upload, just haven’t got to it yet. Just need to take an evening to upload them.

[@sylak2112]

Remid me of the European Space shuttle that never come true. I thought it was cool at the time.

[@richardstansbury7847]

Dream chaser has been a sleeping giant for the private space industry my personal favorite for space tourism as long as it test out as I would expect it will

I got interested in lifting body aircraft after watching Interstellar and falling instantly in love with the Ranger craft. Can't wait to see Dream Chaser fly and hopefully get greenlit for manned missions. Great video!

[@ruairidhmunro]

Dreamchaser is such a cool looking concept. It's a shame that they were not awarded a contract as part of CRS/CCT and NASA (read Congress) decided to subsidise Beoing Starliner. I've a feeling Dreamchaser would have flown long ago had it not been for politics.

[@tomamberg5361]

Back when the contracts were awarded, Boeing was not the mess it's been the past few years. (We all hope they're crawling out of their woes, for the good of the country, at least...)

Always the best content

[@leonbarnes1402]

im 100% for dreamchaser, it does need to get a crew rating though. way better than dropping people back to earth in a tin can with parachutes. though it does remind me of farscape 1 from farscape, but its clear where their inspiration came from. id rather see it launch on a falcon though

[@ghost307]

I always thought that Farscape 1 was inspired by the rescue craft in the movie 'Marooned'.

[@lordgarion514]

And how many people have died in tin cans with parachutes, compared to the space shuttle?

[@TheEvilmooseofdoom]

@@lordgarion514 I think it's 1:1 in terms of mission lost. Different on body count but that's because nothing else carried as many bodies as the shuttle.

[@HellToupee1]

@@TheEvilmooseofdoom difference is those tin can failures happened in the first generation craft when lessons were still being learnt while both failure modes of the shuttle were unlikely to happen to a capsule while capsules have proven to survive aborting booster failures on the pad and inflight.

[@ronjon7942]

I’m guessing it’d eventually ride on the F9, but Sierra, ULA, and NASA have been working on this together for a long time: prolly since Sierra’s inception in 2004 with NASA, and maybe as early as 2006 when ULA was founded. Looking at the executives, it seems to me several people likely knew each for even longer. Since the Vulcan already has 70 Vulcan missions sold, including 7 for Tenacity, Vulcan’s prolly going to be first choice for Sierra for some time, especially as it obtains it’s human rating. My prediction is the Ariane 6 will be certified for the Dream Chaser next, well before Falcon9, so the ESA can contribute it’s resources to replenishing and remanning the ISS.

An excellent, clear, and fascinating look at the history of lifting body space planes and the genesis of the Dream Chaser. Thanks, Scott.

[@Gogreenoo3]

Excellent video Scott! Great compilation of clips and history. You got so much more correct about the Dream Chaser and it's history than any other reporting or commenting I've seen over the years.

[@bob19611000]

Granted unmanned but the "X-23 Prime" was also a lifting body subscale that made it to space and returned.

[@PedroRafael]

These are good news. Fingers crossed it makes in maiden voyage this year, that would be cool. Thank you for the details and bits of history!

I've always been fascinated by the old lifting body X-planes. It's cool to see that the concept will finally make it into an operational spacecraft!

[@AKknapper]

My uncle worked on the X36 for a while in his time at NASA, it's nice to see that not everything from that development was thrown out when it was defunded!
