Former NASA official on trying to stop SLS: “There was just such visible hostility”

I am still amazed how they can burn 10 billion and not have much to show for it.

Keeping production lines open? The Air Force has paid billions for readiness programs before.

I don't agree with keeping obsolete and expensive tech around but that's part of the military-industrial pork complex. Force military contractors to get lean or be prepared to keep them big and afloat.

Really great insight. I can't wait to read Escaping Gravity to get the full story.

One nitpick -- it's important the spaceflight community views Starship with a pragmatic attitude. Lori's presented quotes discuss Starship like its a certainty, but it certainly is not. In a way I feel like SpaceX suffers from their own success with the public in this regard. We are so used to their success we forget how incredibly daring Starship as a vehicle and spaceflight architecture is. True innovation always comes with a corresponding large amount of risk. SpaceX and NASA are definitely pushing the envelope here, and the public should keep in mind that daring great things requires a steely eyed acceptance that things may go wrong.

Bolden is still against Starship to this day because "it's too big".
It's going to be impossible for NASA to use because cost modeling they use is basically "1kg = $this much", so suddenly having such a large launch capacity will screw this.

That's not true. With commercial companies, the government pays for a service. With SLS, the government was buying a capability.
I'm talking about building something to go into Starship. It represents a huge opportunity to completely change the way we think about building satellites and probes, suddenly being essentially freed of mass restrictions and so cripple us when designing spacecraft. It will take a sea change as NASA to take advantage of this, one they are not currently planning for.

Wrong. They already see the potential. Its part of why they will rent out lab space in someone else space station in the future. Its part of future moonbase proposals. NASA and JPL will have no issues whatsoever in not worrying about cutting mass, in everything and anything they launch.

Its also part and parcel of having their launch costs slashed, which they have already seen, leaving room for more payload.

Are you going to follow up by telling us how the other government dinosaurs are not prepared for Starship and need a sea change also? The USAF already allocated $50M last year in funds to study (semi) ballistic lift concepts.

My sense of things is that I believe Garver's narrative as outlined here.

I do have a question, though: is there ANY narrative out there, one that makes sense, that opposes Garver's views (as expressed here)?

My oh my what a boondoggle.

The narrative from Nelson and Hutchison, both of whom I have spoken with about this topic, is that they were working to preserve NASA's (and by extension that of the United States) launch work force. They felt that American capabilities in large launch vehicles, and solid rocket motors, and high-energy propulsion, needed to be conserved. So in their minds they were "keeping the band together" to ensure that the United States retained these key capabilities as strategic national assets. They also felt that by giving up Constellation, the Obama administration was turning away from human spaceflight for good.

That's a very lightweight argument. Delta IV and Atlas V cover large vehicles (the Delta IV Heavy), high energy propulsion (with the RS-68 (D-IV) and RL-10 (both D-IV and A-V)) and solid rocket motors (with both ATK and AJR providing SRBs for D-IV and A-V). Start a long-term program for a RD-180 replacement and you've now got a 100% homegrown launch capability. And doing something like getting Orion launching on an Atlas or Delta would probably have gotten it launching sooner than waiting for SLS to show up.
It seems to me that "keeping the band together" is actually "keeping the band playing the same tunes in the same venue".

Damn, Eric is on fire this week. What's next, an interview with Gwynne Shotwell?

Headed to Boca Chica this evening for the SpaceX and T-Mobile announcement, and then Florida's Space Coast this weekend for the Artemis I launch. So yeah, busy times.
I'm sorry you have to go to Melbourne. Maybe you can hop over to Orlando for a few days during the first couple of SLS scrubs.

Melbourne's slow, but at least it's not Mims. Nothing good comes from Mims or Micco. And yeah, Orlando's not that bad of a drive (when I lived in Melbourne, I had family living in Orlando), and even Jacksonville, Miami, or Tampa are within driving range for day trips (I made all those drives multiple times).

Unfortunately, Edelweiss closed last year, so there's no longer a place I can recommend for German food (yes, there's the Biergarten downtown; I can't recommend any place for German food in Melbourne).

Nothing but speculation. Not sure if there was/is a news embargo, but this was only released just yesterday, with little more information than "there will be an announcement".
My own speculation:

Boring version: T-Mobile is going to use Starlink for backhaul.

Super-speculative version: SpaceX is going to use T-Mobile's spectrum to provide direct cellular service. That wouldn't be a Starlink satellite as they exist now, but I do know at least a few groups are working on schemes where that would work.
It won’t do anything for my (lack of) reception in the back of Costco and a nearby Mallwart, but outdoor connectivity deep into the forests and mountains where no carrier’s signal currently reaches would be a game-changer, even if it’s just enough to send some texts or make a call.

Come to think of it, even improved backhaul would be a welcome upgrade.

As a launch vehicle there's nothing particularly daring with Starship. It's made of stainless steel which is odd but not unheard of. But in terms of launching many tonnes of mass to orbit there's nothing novel. It's the landing and reuse goals that are new.

But Starship would be completely superior to SLS in every metric (performance and financial) without reuse of any part at all. So Starship succeeding as a disposable launcher is as much a certainty as ULA's Vulcan or any other rocket that hasn't yet flown. When dealing with an experienced launch provider, there's no reason to assume a new rocket won't make orbit within the first few attempts.

That's still chump change compared to the F-35 development. Not sure which was less worth it, either.
F-35 replaces several aircraft (including the aging Harrier) and will help defend the interests of the US and Allies, SLS will fly every one or two years until it collapses under the weight of being compared to the commercial offers

F-35 is also similar in price (or even cheaper!) than other modern fighter aircraft on the market, like the Rafale. The SLS is an order of magnitude more expensive than current competition, and even at least twice as expensive as (and less capable than) the 60 year old Saturn V.

I wish SLS got the bad press that F-35 gets, it deserves it more.

It should be interesting to see which way Switzerland goes. They are looking at F-35s, but France is trying to woo them with some discounts for Rafales.

I think the backhaul is definitely part of it, but I can't see Elon coming out for that — it's not big enough, flashy enough a thing for him. I also don't think we're going to see something ala ASTS, though I'd like to be proven wrong — I would welcome a Thuraya-like SatSleeve or satellite hotspot.

Best guess is that they're going to allow you to fall back on T-Mo's 5G if you're a Starlink customer with the hardware already in rectangular Dishy, and if you're on T-Mo, you'll get priority for Dishy. Something along those lines.

Starship doesn't have to be full when it launches to orbit. Most other customers won't be able to figure out how to use 100-150 tonnes of payload capacity either.

Exactly. SpaceX will likely just fill the rest with Startlink sats, just like they've done with a handful of rideshare missions on Falcon.

No, not really. This is about SLS, which doesn't take people to the ISS, not commercial crew, which the congressional dipshits thought should go to Boeing/Starliner only.

/s

Fascinating interview - a couple of brutal answers in the middle.

Beyond SLS, It's a shame that Ms Garver has to place so much faith in SpaceX. I know New Glenn is name checked, but we all know there seems to be a bit too much Graditim there. Interesting that BO have been promoting their non-rocket interests on Twitter recently - perhaps that will be their distinction over SpaceX and their fairly strong transportation focus.

Additionally, it's not like expertise in solid rocket motors is going anywhere. The DoD uses lots of solids-propelled devices and the ICBM renewal provides far more money to SRBs than SLS ever could.

Following the EELV Atlas development plan would have maintained work on SRBs (since Atlas Phase 1 had configurations from 0 to 6 SRBs) and gotten to a super-heavy launcher (Phase 3 was between 105 and 178 tonnes to a 220 nm circular orbit at 28.5 degrees depending on options and configuration).

All of it was fairly incremental development, too. The biggest change was probably the first one, building Atlas tanks at Delta diameter. Other planned upgrades were adding a second engine to the core, then stretching Centaur and adding more RL-10 to the upper, then adding extra cores and (eventually) cross-feeding them so the main core didn't have to throttle down for the side cores to burn out first. Eventually they'd trade some payload mass for a larger fairing once they started getting volume-constrained rather than mass-constrained.

There was also some thought of using Boctane to eke out a little more performance, but I think they'd have come to the same conclusion that the Russians did with Syntin, that it was too expensive for the minimal gains achieved.

I was at Boeing Houston during that particular time, and the angry rhetoric toward Obama that was echoing up and down the halls was something else. The crazy level started at "Obama's gonna fire us all and give NASA's money to the democrats!" and went rapidly north from there. The spin that we were fed—from internal boeing news emails, from management, from senior leadership—was that Obama hated NASA, hated space, and hated us. It was pretty poisonous stuff.

I am still amazed how they can burn 10 billion and not have much to show for it.

But the ultimate goal of the F-35 was to actually fly in an operational sense. And while it may not be perfect, it does actually do that. And unlike SLS, per hour operational costs aren’t crazy out of line with other high-performance military jets. However it does suffer from the B-2 problem of being so expensive that you can’t use it on more risky missions, where it’s stealth and other functions are at highest advantage over older aircraft.

It's a very reasonable-sounding load of horse crap and they know it.

By the time Constellation was cancelled and SLS was finally authorized most of the people employed by the Shuttle program had left their various employers. There was a gap of several years. And, as I pointed out above, the solids rocket community is well fed by the DoD. It's not going anywhere.

To emphasize the scale difference another way, the empty shell of a space shuttle's SRB, with no propellant loaded, was a few tons heavier than a fully fueled and armed Peacekeeper (~200,000 pounds to 193,460 pounds). Fuel for the SRB massed 5.5 times as much as the empty shell. The SLS SRBs are bigger still because of the extra segment.

T-Mobile already uses any available WiFi around to place calls if you enable that option. So while bundling might be good, it's not like T-Mobile needs Starlink's WiFi to enable service.

I want SLS to succeed on Monday because for the cost it had damn well better succeed. But unfortunately success will not remove the albatross from NASA's neck quickly enough. Like so much I see around me there are these old entrenched interests standing in the way saying, "Why are you not on the other side of us?"

I feel sorry for the people who've worked on it for so long, but I'd quite like it to fail badly. There might be nothing as effective as a colossal and very public RUD to put a stop to throwing good money after bad.

Really great insight. I can't wait to read Escaping Gravity to get the full story.

One nitpick -- it's important the spaceflight community views Starship with a pragmatic attitude. Lori's presented quotes discuss Starship like its a certainty, but it certainly is not. In a way I feel like SpaceX suffers from their own success with the public in this regard. We are so used to their success we forget how incredibly daring Starship as a vehicle and spaceflight architecture is. True innovation always comes with a corresponding large amount of risk. SpaceX and NASA are definitely pushing the envelope here, and the public should keep in mind that daring great things requires a steely eyed acceptance that things may go wrong.
As a launch vehicle there's nothing particularly daring with Starship. It's made of stainless steel which is odd but not unheard of. But in terms of launching many tonnes of mass to orbit there's nothing novel. It's the landing and reuse goals that are new.

But Starship would be completely superior to SLS in every metric (performance and financial) without reuse of any part at all. So Starship succeeding as a disposable launcher is as much a certainty as ULA's Vulcan or any other rocket that hasn't yet flown. When dealing with an experienced launch provider, there's no reason to assume a new rocket won't make orbit within the first few attempts.
Almost. SLS is "better" than Starship for deep space missions, using the forced logic that the Earth-to-orbit launch vehicle must also propel you into deep space. That last "gap" falls apart if you accept the use of optional upper stages as part of the payload.

Yup. SLS is only 'better' than Starship in that one usage if you intentionally put a bunch of artificial 'requirements' on the mission that deliberately negate the massive advantages Starship brings to the table -- requirements that Starship makes obsolete and irrelevant.

It's like how politicians have contracts written in very specific ways to ensure only one company is even eligible (usually, notably, with direct ties to the politicians in question).

I think you're right about Starship beating SLS across the board (advanced technology, payload, launch frequency, development cost, and cost per launch).

It's amazing and disheartening at the same time that NASA has to pay $100M per copy for a non-reusable version of the RS-25 hydrolox engine that powered the Space Shuttle 40 years ago and SpaceX is developing a superior reusable methalox engine, the Raptor 2, for Starship for $1M per copy. To me, that's the most glaring disconnect between New Space and Old Space.

I think that the worry regarding Starship's first orbital test flight is that there is a big unknown--can 33 Raptor 2 engines operate as planned for 150 seconds from liftoff to staging?

Rather than building a test stand with more than twice the capability of the B-2 facility at Stennis that was used to fully ground test the first and second stages of the Saturn V, Elon has decided to roll the dice and launch Starship without such a test.

This is new territory for SpaceX. Previously, the Falcon 1, Falcon 9, and Falcon Heavy were completely ground tested (full thrust, full duration) prior to the first launch. With Falcon Heavy, the largest unknown on that first flight was whether the two side boosters would jettison as planned. They worked OK and Elon's Roadster was sent to Mars.

Exactly. Starship has the performance to lift the wet mass of ICPS + Orion + ESM. Perhaps such a solution couldn't be a lifting body shape for the second stage but if SpaceX has to settle on no reuse there's no reason for that shape. A traditional cylinder with engines underneath is enough.

Yes, it's a three-stage rocket system for TLI. So is SLS.
