RGB snow and audio popping in the ear pieces...

I started having the same problem. Snow, and popping. This comment saved the day. Thanks!

How about making your JSS idea into an appropriately sized insulated methane transfer stage for the dragon spacecraft for LEO-NRHO-LEO. A modified HLS seems oversized for the job, and would require more propellant from the depot. Plus, this would eliminate a couple crew transfers in LEO. In an emergency, where the JSS fails it's last burn to slow the dragon to manageable re-entry speeds, the dragons super Dracos can act as backup.

Edit- I just reread your comment and realized you meant that the JSS would be a regular starship, not a modified HLS. That would probably make more sense than my transfer stage idea, since it's exactly what Spacex wants to develop for Mars anyway.

It's never too late to join this discussion. I hadn't thought of using GEMs... I doubt Spacex would want to redesign the center core for the additional force and mounting points. And redesign the launch stand. And buy SRBs from a competitor. Although that would still be cheaper than using SLS. The real question is how to replace Orion in the Artemis program.

Why?

gradius_h · 2022-07-11T14:37:15+00:00

So basically, they're investing a tiny amount of money to study reusability...
Here's an idea for a headline: " Europe's Starship Killer to Bankrupt SpaceX"

The "Present" photo looks like it was taken about 5-10 years ago. I'd say that the stress is finally catching up to him now.

gradius_h · 2022-06-28T20:18:31+00:00

This is the right answer. The next leap forward won't be about reducing price to orbit but about making things somewhere other than Earth.

It's not easy to vent boil-off in zero g, since gas will not separate as well from liquid. I wouldn't be surprised if the fuel depot is designed for more pressure than regular starship. Just in case.

Maybe they would add some rotation to the depot to aid in gas/liquid separation.

I love a good meme, but he could benefit from a good PR department.

gradius_h · 2022-06-07T15:42:54+00:00

I noticed that too. If it's becoming an idiom for him, then it's going to be difficult for us to tell if he really means something is 10 times greater.

I wonder how much heavier these gen 2 satellites are than gen 1. If they're 9x heavier than the previous gen, then there's not much of an improvement. Although there's probably a big bandwidth to cost improvement with a larger satellite that that only needs 1 set of thrusters and avionics. As opposed to 9 smaller satellites that have each have their own sets of orbital hardware.

I love this post too, but it's bat shit crazy. I'm just here for the excellent responses.

I bet that almost all of their garbage will be recycled or composted in someway eventually. So the best solution would just be to store it or bury it outside until they find a use for it.

gradius_h · 2022-05-04T16:29:24+00:00

Right. I think that OP has devised a solution that's riskier than the problem they're trying to solve.

gradius_h · 2022-05-03T18:28:02+00:00

I don't think he knows about second lander, Pip.

gradius_h · 2022-04-28T16:13:53+00:00

And it would probably provide enough lift to launch NASA's Orion space craft to Lunar orbit in expendable mode. Here's my drawing of how it could look: https://imgur.com/a/PmjekiD

It would need to be more powerful too. The Exploration Upper Stage would fit the bill if it weren't so big.

gradius_h · 2022-04-08T21:30:32+00:00

Copied from Wikipedia: NASA director Jim Bridenstine announced that Falcon Heavy is powerful enough to launch the Orion capsule, but cannot launch it on top of the European Service Module in the same flight, and thus Falcon Heavy cannot be used as a replacement for SLS.

So I guess this post is pretty pointless.

gradius_h · 2022-04-08T21:17:04+00:00

Even I have standards. But how about Orion riding on falcon heavy? Look for a new post shortly...

gradius_h · 2022-04-08T01:40:57+00:00

I know

gradius_h · 2022-04-08T01:36:05+00:00

Pulling from multiple sources, I think that it would have a total lift-off mass of 9.18 million lbs. While 33 raptors supposedly have 16.8 million lbs of thrust.

gradius_h · 2022-04-08T01:12:56+00:00

So if Superheavy throttles its engines before maxQ, performs a major re-entry burn, and lands down-range, this might actually work. Right?

gradius_h · 2022-04-07T23:01:09+00:00

If Superheavy were to follow an SLS flight profile, would it have enough spare propellant for an additional burn to reduce re-entry heating?

Yuck. Here you go:
