Wonderful Video David! As a founding member of the DIRECT team I certainly appreciate how well you conveyed the history of our efforts. The only thing I would add is that I wish you had touched a little on the presentation to the Augustine Commission, and that from day one DIRECT was about preserving and re-tasking the incredible NASA workforce that brought us the Space Shuttle Program. Thank you again.
Hi Philip, I made a companion to this video that goes a little more in depth into the design history and thought behind the team's proposal(s).
You can watch it here if you'd like czcams.com/video/tui0bJqhK_4/video.html
I can confirm it is a good video!
@@DavidWillisSLS SLS rockets and Orion capsules are essentially very old technologies, they are repeating the technologies of Apollo-Saturn. Why doesn't NASA use new technologies such as space refueling depots, in-orbit assembly, space tugs, and nuclear or plasma propulsion systems?
@@powerfulstrong5673 they need to keep shuttle jobs and congress wouldnt let them, and hey whatever works, works right?
@@landonrounsavall1125 The Space Shuttle should not be canceled!
SLS descended directly from Jupiter…I remember their website …was a worthy idea.. great vid that was overdue!!
Nice video! Really wish original Jupiter rockets became a real thing
Engine section is really curse though lol
Keep watching the video ;)
@@DavidWillisSLS lol omg no way
Very cool so as I understand directs Jupiter was never meant to fly but instead show NASA what it could design.
YOOOOOOOOOOOOOO THE BEST ROCKET THAT NEVER HAPPENED
*coughs
@@Plab1402 ok so maybe i did forget about sea dragon
*coughs again
@@Plab1402 bro nothing beats Sea Dragon what you talking bout
@@HypersonicWyvern *coughs as well
Oh my.....wow! This is the SINGLE VIDEO ABOUT DIRECT JUPITER that I found and takes those informations seriously, and makes about it VERY SERIOUS video! WOW! THANK YOU SOOOOO MUCH!
Extremely well-made video! Congrats David, I hope there is more to come!
I come back to this video every now and then just to imagine what could have been
This!
Thanks David, great video!
THANKS FOR UPLOADING THIS ! ! ! I HAD COMPLETELY FORGOTTEN ABOUT DIRECT AND IT WAS GOOD TO SEE THIS VIDEO AND REMIND MYSELF WHAT THIS PROGRAM WAS ABOUT ! ! ! 👍👍👍👍👍👍👍
Megapoggers, mate. Your videos are underrated.
For DIRECT, I think it had some structural problems meaning that the tanks needed the modifications done on SLS. The LH2 tank was essentially "hanging" from the SRB strut, which meant that it was quite flimsy but lightweight. Compare its weight to the Energia core and you'll know what I mean. It likely would've broken apart with RS-25s on the bottom, or at least come uncomfortably close. The margins in general were just too close and it had some overtly optimistic assumptions, which is why going with SLS instead of DIRECT was the right call.
Great video! Thanks David! Martin from Space Intelligence
My daily dose of NASA content,love it.
Nice, love it
Very nice!
Good stuff!
Great video! DIRECT certainly was an interesting program.
Too bad the Direct Team didn't head the SLS program instead, cause it's definitely not getting $4,800/kg now (it's ~$15,400/kg for the first three, not including dev costs). 😅
Well that number was assuming 5 flights per year. Not sure what 1 launch per year would’ve been. The PDF didn’t say
Now I know where the name Jupiter IV for SLS comes from
Nicely done my friend! :D
Thank you Matt!
Amazing, can’t wait for the launch of sls
Narration speed is perfect now. Your earlier videos were a bit too fast.
lets give him some views boys (EDIT: finished watching, its worth it. Good job Willis!)
superior launch system
Good information...great music too ;-)
Thank you!
Beautiful
Nice!
Great!
Very epic
Thank you!
Nice
Great video but I'm going to point out that there were SDVs being studied since before shuttle flew.
Yup! But DIRECT was the last one ever! (Cuz I doubt there will be any others after SLS)
banger vid
Thank you!
nice
Do the two launches fight or something? ;) (6:30)
OOF oh my god. im such an idiot
Very awesome and informative video! Do you plan on making other videos for other SDLV's?
Perhaps sometime in the future yeah!

Do one on the Jupiter III
I’ll consider that for sure!
Anyone have a link for the ''mood'' music used in this video cause i cant find it anywhere :(
Question what if the Orbiter was modified and put on top of the Jupiter stage?
The aerodynamics wouldn’t work. Your center of lift would be well forward of your center of mass
DIRECT Team used the worm, they were Based.
Hmm, if SLS is direct, then uh, i'm afraid something did not go according to the plan lol
Well the differences between direct and SLS, mainly stretching the rocket, were what caused the plan of direct to be thrown out.
Extremely based video David
My counterpart to this video is now up czcams.com/video/tui0bJqhK_4/video.html
Please skip #6. Go 1, 2, 3, 4, 5, 7... if you must, but not 6.
So you are telling me that SLS is just Jupiter III.
no lmao. that was something... else... haha!
USING THE ROCKET EQUATION IS THERE A LIMIT AS TO HOW BIG YOU CAN BUILD A ROCKET TO LAUNCH BIGGER PAYLOADS AND STILL GET IT OFF THE GROUND ? ? ? 👍👍👍👍👍👍👍
I.e. some curve drawn by the rocket equation creates a vertical asymptote (as opposed to increasingly fast increasing line, like you get from a parabola)? Nope. No theoretical limit, but there certainly are PRACTICAL limits.
There is no limit, however, as MrZ said, it becomes impractical. At some point, small increases in payload require ridiculous increases in fuel. The solution is to not use traditional chemical propulsion.
Why'd Orion's panels get changed from 2 circles to 4 rectangles?
Change from an American to a European Service module I belive
@@DavidWillisSLS Yeah, ESM is ATV derived so they are using the same panels.
The reason that so little progress had been made on the Constellation program 1:30 is simple - it was chronically underfunded. Congress and the Executive branch directed NASA to build the Constellation system, but gave them a ridiculously low budget to do so 😒😒
Underfunded or... Is it perhaps significantly over budget?
WE WERE ROBBED
Hey I heard you have a Discord server?
I do! Links in. The video description!
@@DavidWillisSLS Oh how did I missed that

Dual /= duel
already been pointed out. i made a spelling error. cant fix it now
What about the Jupiter III
that was something else lol
@@DavidWillisSLS 2 Shuttles launching a Saturn V
@@kommandantgalileo Godam why does everything point back to the idea of an orbital construction of the LV that puts the part there.
It's like the Saturn V launching prices of the Saturn V to increase the range.
IDK why my mind is like this.
Ok

This… would have worked. Followed its website & CZcams channel. Shame
