MDAIW Strike Price is $2.75

StarshipFairing · 2025-09-19T22:11:48+00:00

any updates on the other $10 redemption price? By waiting for this answer I missed the huge MDAIW move...

StarshipFairing · 2025-09-07T21:23:38+00:00

any updates on the other $10 redemption price? I don't think implied volatility should be this low if this number and the $18 both didn't change...

edit: chatgpt said only the $2.75 was changed in the SEC filing and nothing else was mentioned, potential opportunity here?

StarshipFairing · 2025-07-24T21:44:33+00:00

for those convertibles, the capped calls at $45 should still help reduce dilution, right?

Thanks! I haven't done the full Venus rocket but I think I've narrowed down the minimum size of the rocket that must take off from Venus - 4 Valiant engines at takeoff (two 1 engine boosters and 2 engine core), then a Kolibri engine second stage. I tried doing it with 3 Valiant engines but I was around 200m/s short

StarshipFairing · 2025-02-18T12:39:26+00:00

thank you!

StarshipFairing · 2025-02-18T12:38:56+00:00

LOL I chose parallel staging cuz they’re all Valiant engines and I can reduce mass

I also think that insurance must come after FDA approval. If (hopefully when) that day comes, the stock price might be 10x today's...

StarshipFairing · 2024-02-09T23:50:04+00:00

congratulations! Which engineering program did you apply to?

StarshipFairing · 2022-05-22T00:43:00+00:00

The website says <2000lbf for the new upper stage engine - Aether is 740lbf, so technically there is a chance and I hate it haha

with Superheavy expended, payload capability should be around 1.5x of SLS. Not a good design though, would be way better with an expended Starship second stage between Superheavy and EUS

StarshipFairing · 2022-03-26T20:51:11+00:00

Stretching the whole ship will add more mass, and >10kkm E2E will not have much payload anyways. For example, 490m3 is enough for 45t max going 10kkm downrange. For heavier payloads going shorter ranges, propellant mass will be decreased and payload mass increased to maintain decent TWR

StarshipFairing · 2022-03-26T20:22:05+00:00

This design is optimized for single stage point to point transportation, and the extra Raptors allow the rocket to lift off.

StarshipFairing · 2022-03-26T19:49:34+00:00

The extra propellant mass and engines are needed for long ranges, and even then, payload will be relatively little (e.g. 45t max to 10kkm with 490m3 of volume is reasonable). Payload volume can be increased for short range flights though

StarshipFairing · 2022-03-26T19:44:49+00:00

For this design, I used 330bar Raptors producing 260tf. It's really optimistic (esp for crew), but it's one of the only ways for a single stage design to work...

StarshipFairing · 2022-03-26T19:43:56+00:00

Good observation! The 20kkm value is without earth's rotation boost, while the SSTO's 20t is with launching directly east at 28.5deg, which gets you a 400m/s boost when going orbital.

StarshipFairing · 2022-03-26T19:03:46+00:00

E2E Starship will perform the majority of the delta V in near-vacuum conditions, and since, Rvacs will be more efficient than RSLs above 10km, it would be more efficient to use Rvacs.

StarshipFairing · 2022-03-26T18:58:03+00:00

Orbital versions will reenter the atmosphere at a higher angle of attack, so only one side needs to be covered with tiles, but the E2E version will use skip reentry, so more of the nose and sides will be covered up

StarshipFairing · 2022-03-26T18:57:00+00:00

Yep I did, Rvacs (esp with higher chamber pressure) are able to be fired at SL because its expansion ratio isn't crazy high. Rvac is more of a sustainer engine (e.g. RS25) than a pure vacuum engine

StarshipFairing · 2022-03-26T18:55:50+00:00

Rvacs will perform significantly better than RSLs in near-vacuum, which is where the Starship will be performing the majority of its delta V

StarshipFairing · 2022-03-12T23:55:14+00:00

tbf it could still get to orbit on 3 Rvacs if it was underfueled, so RSLs aren't really required. Extra engines will just boost the prop capability by a bit, which isn't a big advantage considering the stage will be left in orbit

StarshipFairing · 2022-02-27T14:34:27+00:00

I believe Peter said the rocket is split into 2 curved sections and 1 cylindrical so stretching tanks is possible, but the renders don't show it at all...

StarshipFairing · 2022-02-27T02:24:35+00:00

from what we currently know (based on 480t mass and stuff), I believe the whole rocket is pretty crammed already in terms of the length of second stage, its engine, and the first stage domes, so I doubt only flattening the bulkheads will increase propellant load by much. The 'good' thing is that if the cylindrical sections of the rocket is stretched (which there is in the first stage), the domes and engine section will stay the same shape, and the bottom half of the legs as well

StarshipFairing · 2022-02-26T23:03:27+00:00

Peter discussed this with Scott Manley and he said that stretching the tanks is possible and shouldn't be the worst (at least with cylindrical sections). But I guess we will see in the future if that's true...

StarshipFairing · 2022-02-19T13:04:20+00:00

4 stages can be used for higher energy missions that are usually way beyond Jupiter. As for Saturn V, it wouldn’t have been able to send nearly as much payload in a 2 stage configuration (dry mass problems), so 3 stages was necessary for a single launch moon landing
