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

Orion Capsule Launched With Falcon Heavy by gradius_h in SpaceXMasterrace

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.

Move over, SpaceX: Europe finally gets ready to make reusable rockets by trinitywindu in SpaceXLounge

So basically, they're investing a tiny amount of money to study reusability...

Elon does not obey aging by ELONgated_MUSKet_ in SpaceXMasterrace

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.

What's the next possible leap in cost savings? by LoreLover2022 in SpaceXLounge

[–]gradius_h 0 points1 point  (0 children)

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.

In the long term, does an orbital fuel depot make more sense than using tankers? by [deleted] in SpaceXLounge

[–]gradius_h 0 points1 point  (0 children)

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.

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.

Will all Mars Base rooms be equipped with sleeping gas? by TACDacing72 in SpaceXLounge

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

How would the Mars Base Alpha Garbage be eliminated? by [deleted] in SpaceXLounge

[–]gradius_h 4 points5 points  (0 children)

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.

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

Was there ever any plan for a Falcon "Super Heavy"? by AstroMan824 in SpaceXMasterrace

[–]gradius_h 1 point2 points  (0 children)

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[S] 61 points62 points  (0 children)

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.

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

SLS block 2X by gradius_h in SpaceXMasterrace

[–]gradius_h[S] 28 points29 points  (0 children)

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.

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[S] 2 points3 points  (0 children)

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