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 kzfaq.info/get/bejne/qtuZY8V71s6vj2g.html

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.

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). 😅

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 ? ? ? 👍👍👍👍👍👍👍

@vulture4117 2 жыл бұрын

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.

@jamese9283 2 жыл бұрын

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.

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 😒😒
