Comment on Starship Orbital Test Flight Raises Serious Questions by Jim Hillhouse

In reply to spacerfirstclass.

NASA Folks

Let’s start with the NASA folks you disparage. They, not SpaceX, very nearly flawlessly launched a rocket (ok, an elevator door in the MLP was wrecked) that sent a crew-designed spacecraft to the Moon and farther in space that any crew-designed spacecraft has ever gone, then safely returned to Earth.

So maybe when the folks who manage to do this when none other have know that of which they opine.

Replacing SpaceX Lunar Lander

The point I unsuccessfully made to you was that NASA, by hitching its Artemis III lunar landing to SpaceX’s Starship program, has boxed itself in. ESDMD head Free’s recent comments underscore that point.

And NASA has no recourse but to either hope SpaceX gets back on track, which doesn’t look likely at this point, accelerate Blue Origin’s development of its lunar lander by moving its schedule 3-4 years to the left, which also is unlikely, or retask Artemis III and IV.

Know How

The other point I tried (unsuccessfully) to make about “know-how” was that SpaceX owns its lander IP, all of it. Were SpaceX a NASA contractor building a gov’t owned system such as Orion or SLS, that wouldn’t be the case. Case in point, SLS’s blue-prints, digital, paper, or otherwise, as well as the factory, machinery, etc. are the property of NASA. If NASA turned over the construction of SLS to another contractor, the people building SLS would just transfer to that new contractor.

Yes, those employees’ know-how is critical. And NASA largely succeeded in preserving the Shuttle workforce at Michoud in hopes of retaining its know-how to help with the construction of SLS. But it turns-out that SLS was much more difficult to build than Shuttle’s simple External Tank. The last time a first stage booster with engines was built at Michoud was in 1971, the Saturn S-IC. That was the know-how, which retired decades ago, that would have been more relevant to building SLS’s Core Stage.

Starship Lunar Lander Descent Abort Capability

You previously stated that the Starship lunar lander concept has a descent abort capability. You stated,

“Attachment A01 “Human Landing System Concept of Operations” of the HLS BAA, page 10 “Descent Abort””

First, when you mention a gov’t document to support your claim like that, link it.

And you’re right; Starship should not have been awarded its lunar lander contract. The award was very controversial because a disqualifying point was no descent abort capability.

Here’s something you can do, contact SpaceX and ask for information specifically on the lander’s descent abort capability.

Starship Abort Capability

“Because if they separate the ship from the booster too early, the ship doesn’t have enough delta-v to reach the planned splash down point near Hawaii, I don’t know why this is hard to understand.”

You are saying that having the abort system would have meant that the aborting Starship wouldn’t have had enough delta-V to make it to Hawaii?

It’s also true that if the launch of Artemis I had gone badly, the Orion spacecraft’s abort would have interfered with its eventual successful lunar mission. That’s not the point of a launch abort system.

When a launch abort system engages, the mission is done and it’s just about getting the payload, crew, to a place hopefully far enough away from where the rest of the launcher’s debris is landing. SpaceX lost a valuable piece of hardware because Starship didn’t abort.

You mention that SpaceX’s (NEPA?) statement only covered a splash-down in Hawaii. Ok, so Starship had enough fuel to provide sufficient delta-V eject from SHB and land in Hawaii but not enough to abort from launch and land elsewhere, say at Starbase?

I think Elon’s BS get you all twisted in a knot that prevents you from seeing the forest for the debris he throws up.

Abort System Is A Crucial Path

Pad and launch abort systems are a critical path and are usually tested long before an all-up test flight. Apollo’s first pad abort test was on Nov. 7, 1963. It was used on the Apollo 4 test flight in Nov. 1967. Orion’s first pad abort test was on May 6, 2010. Orion’s abort system was available on last year’s Artemis I test flight. The fact that Starship could, after a successful launch, separate and then land in Hawaii means that the abort system either the capability doesn’t exist, wasn’t activated or failed. I will wait for the FAA mishap report to learn which it was.

SHB FTS

Elon Musk has said that SHB did activate its FTS. If true, that’s good news. And if the FAA mishap report confirms that claim, then I stand corrected. The bad news is that it didn’t work very well. And if SpaceX already redesigned and tested the new FTS, then more good news. Hopefully this new FTS on SHB will destroy the launcher in less than the nearly 2 minutes it took for the first version to do so.

Red Dragon

I knew enough about Red Dragon to read that AIAA paper, among others, in confirming a source’s claim that the mission was BS. So, why don’t you take the trouble to read the paper I referenced (AIAA 2011-7216 is available at https://arc.aiaa.org/doi/pdf/10.2514/6.2011-7216 where you can purchase a copy), focus on page 16, do some of the patched-conic math (see Vallejo’s “Fundamentals of Astrodynamics and Applications, 5th Ed.”, available at https://www.amazon.com/Fundamentals-Astrodynamics-Applications-Fifth-Vallado/dp/1881883221) to get you from LEO, heliocentric, Mars capture, and powered-descent phases, and learn for yourself that Red Dragon, even stripped-down, would never have even made it to Mars with sufficient fuel mass to for a landing in the time frame SpaceX was considering. That’s why Elon eventually canceled it in 2017.

NASA Space Act Agreements

A Space Act Agreement with NASA only means that it will help a company with the resources to the extent the agency can and for the agreed upon sum sufficient to pay for that assistance. That’s all.

Don’t agree with that? Well, then contact NASA HQ’s PAO and ask.

CyberTruck

Hey, I was also on Twitter and saw that CyberTruck won’t be in production later this year. Here’s a link (https://www.motortrend.com/news/tesla-cybertruck-issues-delayed-development-leaked-report-2023/).

FSD?

Comment on Starship Orbital Test Flight Raises Serious Questions by spacerfirstclass

In reply to Jim Hillhouse.

“That’s not the way I see it. Nor increasingly by people within NASA that I talk to. Far from it.”

There has always been a faction inside NASA that opposes private and commercial space, they tried to revolt 10 years ago when Obama proposed Commercial Crew, they’re up to their old tricks now. They were wrong back then, they are wrong today.

“Blue Origin’s contract is for a lander for later Artemis missions starting in 2029. Which leaves about a 2-3 year gap”

Blue Origin’s contract was awarded 2 years later than SpaceX, so of course there’s a 2-3 year gap, that doesn’t change the fact that Blue is proposing a similar architecture as Starship and requires similar (if not harder) tech development. So it’s completely disingenuous to portrait NASA selecting Starship as some sort of mistake while at the same time praising NASA for selecting Blue, you can’t have it both ways.

“You should take to guys at NASA who work with SpaceX. They need help. A lot of help. With Starship. Filling-in craters is one thing. Getting permission to launch again is another.”

You’re moving the goal post, my original comment about “SpaceX doesn’t need gov’t help” is in reply to your claim that there’re “a lot of infrastructure work before the next launch. Some of that work may, likely will, require additional federal government participation.”, you moved the goal post to all the work related to Starship development and launch, that is not what I was replying to.

“Not so with SHB. And why not?”

You’re trying to change the topic again, your original claim is that a GNC failure prevented FTS from being triggered, that’s wrong, it looks like you know it’s wrong and now just trying to change the topic to something else.

Of course they need to investigate why FTS explosive didn’t destroy the booster immediately and fix it. They have already carried out additional FTS test on the ground to aid in the investigation and fix.

“So, let me see if I get this straight. Elon said that the abort capability of Starship wasn’t enabled because that would affect its mission to land in Hawaii? Seriously? How?”

Because if they separate the ship from the booster too early, the ship doesn’t have enough delta-v to reach the planned splash down point near Hawaii, I don’t know why this is hard to understand.

Their environmental assessment only assessed splash down near Hawaii, the exclusive zones they declared is around the splash down point, they’re trying to avoid crashing the ship into somewhere they were not planning to crash into.

“that SpaceX doesn’t yet have the launch abort capability enabled because it hasn’t yet been developed? More likely than not, that’s the reason.”

Sure, that’s a possibility too, it doesn’t contradict what I said. SpaceX concentrates on the critical path, if the launch abort capability is not needed in the near term, there’s no reason to spend resource on it yet.

“Did you know that all of those elements are owned by the government, NASA in particular? That SLS is produced in a government owned facility, Michoud? That the government could take the blue prints of any one of those systems, give those to another contractor, and award a contract to build that system?”

Of course I know that, but there’s this thing called “know-how” that can’t be transferred, isn’t this the reason Congress gave for wanting to preserve the Shuttle workforce? That once the employees are laid off, the knowledge is lost? You can’t have it both ways, either employee know-how is important in which case losing a contractor would be a major blow, if not a death sentence, for SLS/Orion; or employee know-how is not important, in which case since NASA already has all the Shuttle blueprints and facilities, then Congress is wrong for wanting to preserve the Shuttle workforce.

“If SpaceX tomorrow decided to cease Dragon development, absent a clause in the lunar lander contract with NASA, the space agency would be at a complete loss and back to square one on a lunar lander.”

Given that without SpaceX’s bid, NASA wouldn’t be able to afford any lunar lander any way, I don’t see this as a big loss.

And US government depends on commercial vendors on a lot of things, things much more important than lunar lander, so this is hardly a situation unique to SpaceX/NASA. If Microsoft decides to stop supporting Windows and Office, what do you think will happen to all the government computers running them? If Boeing decided to stop supporting 747, what do you think will happen to Air Force One?

“Well, given where SpaceX is, NASA sorta already is.”

So you’re betting HLS Starship won’t happen, is that it? How much are you willing to bet on this?

“Really? What would that be. I’d sure like a document referencing it because my NASA sources at several centers tell me otherwise. But I am 110% confident you don’t have such a document because the descent abort capability doesn’t exist.”

Attachment A01 “Human Landing System Concept of Operations” of the HLS BAA, page 10 “Descent Abort”

It’s part of the HLS conops requirement, you can’t win the contract without it.

This just goes to show how much credibility your NASA sources have…

“Having followed him since the early 2000’s, I can say he is pretty much a constant stream of BS. Don’t agree?”

Oh really? Last time I checked, since early 2000’s he has accomplished pretty much everything he set out to do. He promised Falcon 1, Falcon 9, Falcon Heavy, reusability, Cargo Dragon, Crew Dragon, Starlink, and he got all of them done and done exceptionally well.

“For a vehicle even half as heavy as a stripped-down Dragon, during 2015-2019 it would have been extraordinarily difficult if not impossible for even a FH to launch Red Dragon with enough propellant to enter and land on Mars and then have a smaller payload launch from Mars and get back to Earth.”

You don’t seem to know much about Red Dragon. SpaceX’s own Red Dragon plan doesn’t include sample return from Mars to Earth, the sample return concept called “Red Dragon” is a separate proposal by researchers at NASA Ames, not SpaceX.

SpaceX’s own plan that is called “Red Dragon” is an one way lander, and they have a Space Act Agreement with NASA on this, so clearly NASA doesn’t think this is physically impossible to do.

“Where’s Red Dragon?”

You do realize NASA has way more abandoned plans than Musk ever has? Where is Space Task Group’s plan to land humans on Mars in 1980s? Where is SEI, First Lunar Outpost, Constellation? Where is Shuttle II, Orbital Space Plane, X-33, X-34?

“Probably same place as Cyber Truck, FSD, Twitter, and so on.”

Hehe, I’m using Twitter right now, and Cybertruck will be in production later this year. FSD is very much delayed, but making progress as well, the beta has been distributed to 400,000 Tesla owners in the US.

Comment on Starship Orbital Test Flight Raises Serious Questions by Jim Hillhouse

In reply to spacerfirstclass.

That’s not the way I see it. Nor increasingly by people within NASA that I talk to. Far from it.

Here are my point-by-point rebuttals.

– Blue Origin’s contract is for a lander for later Artemis missions starting in 2029. Which leaves about a 2-3 year gap, if all goes well for Blue, between SpaceX’s scheduled landing for Artemis III sometime in 2026 or so. I do applaud NASA making this agreement.

– SpaceX doesn’t need gov’t help
You should take to guys at NASA who work with SpaceX. They need help. A lot of help. With Starship. Filling-in craters is one thing. Getting permission to launch again is another. Are you on the FAA mishap team? Me neither. So let’s wait and see on this. Also, keep an eye on the DC Circuit Court.

– SHB FTS activated after all
How long did it take the Booster FTS to actually destroy the vehicle? A minute? A minute and a half? Two minutes? And given that time gap, how far would the Booster travel had it been oriented on a trajectory towards say, Brownsville? Most…no, all FTS’s seem able to disassemble a launch vehicle in a few seconds because they have strip charges that split the vehicle wide-open. Not so with SHB. And why not?

– Starship Abort Capability
So, let me see if I get this straight. Elon said that the abort capability of Starship wasn’t enabled because that would affect its mission to land in Hawaii? Seriously? How? I mean, Orion has a LAS, and its service module is a later stage of launch abort system, and that doesn’t seem to affect its ability to orbit the Moon. How does enabling the abort system of Starship affect its ability to subsequently proceed in other mission activities? Or are you telling me, without realizing it, that SpaceX doesn’t yet have the launch abort capability enabled because it hasn’t yet been developed? More likely than not, that’s the reason.

– Orion depends on Lockheed Martin – a single company, SLS core stage depends on Boeing – a simple company, SLS booster depends on Northrop Grumman
Did you know that all of those elements are owned by the government, NASA in particular? That SLS is produced in a government owned facility, Michoud? That the government could take the blue prints of any one of those systems, give those to another contractor, and award a contract to build that system? That is patently not the case with any of the commercial entities save only if companies file for dissolution, provided that a substantial amount of their funding came from NASA. If SpaceX tomorrow decided to cease Dragon development, absent a clause in the lunar lander contract with NASA, the space agency would be at a complete loss and back to square one on a lunar lander. Well, given where SpaceX is, NASA sorta already is.

–Starship Lunar Lander has a descent abort capability
Really? What would that be. I’d sure like a document referencing it because my NASA sources at several centers tell me otherwise. But I am 110% confident you don’t have such a document because the descent abort capability doesn’t exist. Instead, if something goes wrong on a Starship Lunar Lander during descent, the abort capability is for the astronauts to (hopefully) have enough time to say good-bye to their families while they wait to become permanent monuments to human spaceflight.

I’m going to penultimately close by noting that Elon is about as straight a talker as a circle. Breathlessly repeating what he says as your “evidence” isn’t going to change many minds, save his fan club. Having followed him since the early 2000’s, I can say he is pretty much a constant stream of BS. Don’t agree?

Let’s walk down memory lane towards several years ago, to 2015, to recall Elon’s Red Dragon PR stunt. Why is it BS? If you know the optimal trajectory windows for Earth-Mars missions, you needn’t ask. See AIAA 2011-7216. Per that paper, “The orbital mechanics cycle of the Earth and Mars has a period of 15 years, and a minimal delta-V phase of the cycle in the early 2030’s.” For a vehicle even half as heavy as a stripped-down Dragon, during 2015-2019 it would have been extraordinarily difficult if not impossible for even a FH to launch Red Dragon with enough propellant to enter and land on Mars and then have a smaller payload launch from Mars and get back to Earth. Where’s Red Dragon? Probably same place as Cyber Truck, FSD, Twitter, and so on.

Comment on “Why I Wasn’t Devastated”: Remembering the Shuttle’s Last Visit to Mir, 25 Years On by Charles Phillips

I worked the entire Mir program from Early Progress through to the end. It was exciting but the Mir was such a compromised vehicle that it was NEVER safe to fly in. I worked closely with Shannon Lucid, Dave Wolf, Mike Foale, etc and the Russian attitude towards safety was not acceptable. NASA didn’t take safety seriously but the Russians thought it was not needed.

“Why I Wasn’t Devastated”: Remembering the Shuttle’s Last Visit to Mir, 25 Years On

OTD in 1998, the world realized why @AstroWendyL wasn't devastated at missing out on a long mission to Russia's Mir space station. Her reason? She got 2 shuttle flights for the price of one.
