What Fresh Hell Is This?

ATK is making noises about commercializing Ares 1. Unsurprisingly, it's full of bovine excrement right off the bat:

Ron Dittemore, president of ATK Launch Systems, said the human-rating that led NASA to build the Ares I first stage around the shuttle booster should also be attractive to other customers with "high-value" payloads, including the Defense Dept. and the National Reconnaissance Office (NRO).


"Ares I can deliver humans, can deliver payload to low Earth orbit; it can deliver payload to geosynchronous Earth orbit and beyond - planetary missions - it's got that much capability," Dittemore said at the 24th National Space Symposium here. "And what's unique is that since we're designing this vehicle with human reliability, proven demonstrated systems, high-value payload customers may see a real attractiveness to putting either DOD or NRO payloads on this launch system."

First of all, the Shuttle booster is not "human rated." The Shuttle itself is not, and never has been, human-rated (I've said it before, and I'll say it again: I wish that we could expunge the phrase "human rating" from our vocabulary--very few phrases in the space business are as misunderstood and misused by so many as this one). What he means is that the fact that they have been willing to use the SRB for the Shuttle (despite the fact that in the case of Challenger, it destroyed the vehicle and killed the crew) led them to decide that it was reliable enough to use for Ares.

One of the things that people don't understand about "human rating" is that it is not (just) about reliability, which is the probability of mission success. Human rating is about safety, which is a different thing. It is about the ability to know when the mission is about to go sour, and the ability to safely get away from the vehicle before it does. So while reliability is nice, what's much more important is warning time and escapability, from the launch pad all the way to orbit (something that the Shuttle has never had, which is why it's not human rated).

But satellites aren't going to have a launch escape system, so they don't care about human rating. What they care about is reliability, and I have seen zero evidence that Ares is going to be more reliable than either Delta IV or Atlas V. Human rating the latter two vehicles will not involve making them more reliable--it will involve putting in the systems needed for adequate failure onset detection (FOSD) and ensuring that they have adequate performance to eliminate abort blackout zones throughout their trajectory (something much more difficult for the Delta than the Atlas, due to to its underpowered second stage). So from a mission assurance standpoint, Ares has nothing to offer to a satellite owner over the current commercial vehicles.

Moreover, there is no discussion of cost. Even if they can get away with not having to amortize development, because the government paid for it and it's sunk, how much of an army will a NASA-developed/operated vehicle require? History would indicate a pretty large one, particularly given the politics of the situation. So will a commercial launch have to pay its share of the annual fixed operating costs, or will ATK (unfairly) be able to subsidize and undercut the ULA by only paying marginal costs for the launch, and having NASA pay the freight for the rest? And it will have to use the VAB for processing, and the NASA pad for launch. Will NASA be reimbursed for the use of its facilities? How much?

This seems like a huge potential bucket of worms, and all because NASA decided that it had to develop its own launch vehicle.

Is ATK serious? I doubt it. I suspect that this is just a PR move to maintain political support for it among the rubes inside the Beltway who don't understand these issues, to show that it has applications beyond the NASA lunar (and ISS) missions. Unfortunately, it may work.

[Update a couple minutes later]

Oh, and how could I forget this? How thrilled will the satellite owners be to put their bird on the paint mixer that is the Ares 1, on top of that five-segment solid, when they can get a smooth ride on a Delta or Atlas?

Yes! Yes! Commercialize the Ares 1!

Have NASA offer a contract to whatever firm can come up with the payload of the Ares 1 to the desired orbit wihin stated performance paramenters. Then let ATK go out to raise the money to develop the Ares, and recover the expense from the profits on government and private sales. NASA can charge them for use of KSC according to the formula other private launchers use.

Oh, wait. Maybe that's not what they mean by 'commercialization".

Never mind.

I'm quite confident that he does, Mark. What's your point? That because we were dumb enough to do it once, we should do it again, on a much less commercially promising vehicle, for which the market is glutted?

Jonathan Goff wrote:

Rand,
I agree with most of your assessment, but wanted to make one point. As you're apt to point out, an expensive GEO satellite is probably just as important as crew or passengers on a launch vehicle. So, I think the idea that people have to have a launch escape system, while $500M satellites can just take their chances is a philosophy that isn't going to last too much longer. Especially once you have orbital propellant depots, I think the case for putting some sort of escape system even on satellite flights will start to make sense. Sure, it bites into your payload, but if you design the launch so that the upper stage spends most of its propellant getting into LEO, tops off at a depot, and then delivers the satellite directly to GEO, any and all GEO satellites could easily be launched on an Atlas V 401. If your station is in the right orbit, you could even top it off using the cheapest LVs available--Dneprs, Soyuzes, Protons, etc.

Why should billion dollar payloads still have to play Russian Roulette getting to orbit?

Not going to happen that way. The comsat guys are incredibly conservative and their launch costs are only 19% of their total systems cost anyway, so why introduce increased risk into the equation.

It is hard enough to get them to accept generic life extension.

This just does not compute.

Karl Hallowell wrote:

That's a good point. Still you'd have to engineer the payload to handle the abort accelerations. That might be more expensive than taking your chances.

Jonathan Goff wrote:

Mark,
When DoD did the EELVs, there was a) a competition, b) a requirement for each of the teams to put substantial financial skin-in-the-game, and c) the competitors had to build, and operate their own launch sites.

Boeing, IIRC put up about 2/3rds of the development cost of Delta IV, including building two new launch sites.

LM, IIRC put up somewhere north of 1/2 the development cost of Atlas V, including building a new launch site (and now a second one as well).

SpaceX had already started development of Falcon IX when COTS came around. It competed. It's going to build and operate its own launch sites (three of them actually). And even with COTS and DARPA it's putting up something like 2/3 or more of the required capital.

Even Orbital is putting skin in the game, had to compete to get money, and is having to do its own launch infrastructure.

Ares-I, OTOH is a 100% government funded venture, was not competed, and all the launch infrastructure is 100% government owned.

Are you seriously trying to make the argument that Ares-I is just like EELV or COTS? If so, that shows a certain ignorance of how these all worked.

Now, if ATK had competed for the Constellation contract, was putting up 1/2-2/3rds of the required capital, and was going to be owning and operating its own launch sites, they'd have just as much rights to commercial business as either EELV or COTS competitors. But as it stands right now, Ares-I is nothing like either of them.

Jon, the point is that there are no launch vehicles in existence or in development (except for the suborbital cruise ships being built by Scaled Composites, et al) that can be defined as "purely commercial." The rest consists of relatively meaningless details.

Jon, those are all good points. Too bad the US Congress has proved itself quite willing to squelch competitive markets with massive subsidies to politically well-connected constituencies. Just look at public education, or anything related to agriculture.

Let me translate. "relatively meaningless details" = "arguments too complicated for Mark to understand, but of quite cogent legal significance."

I'm sure additional Ares flights for unmanned satellites might save a few jobs at KSC, and make the system seem worth developing at all. As Rand says, nice candy for people who are ignorant of reality.

Ares I doesn't provide a capability that is not already available with other launchers. Launchers that have a track record and are available today at a lower cost, and can be launched in other locations than just KSC.

I do think Ares V might provide some additional capabilities. If NASA must continue giving bones to ATK, then I don't know why we don't just skip Ares I, develop Ares V, and make better use of the additional upmass, rather than make better use of a shaky, underpowered lifter that is Ares I.

Rand, A minor quibble with your reliability/safety argument: In aviation it is common to provide crew escape systems in aircraft which aren't all that reliable or where the nature of the mission may make the aircraft unreliable(ultralights, sailplanes,jet fighters/bombers,aerobatic aircraft)but have no crew or passenger escape where the mission environment is more benign or the aircraft made more reliable with redundant systems etc(light aircraft, jet airliners).
Do SS2 or Lynx have crew/passenger escape systems?

Rand Simberg wrote:

Do SS2 or Lynx have crew/passenger escape systems?

Lynx is an open question at this point, I think. They may be considering ejection seats, but you'd have to ask XCOR. SS2 does not. It's Virgin/Burt's intent to make it sufficiently reliable that it's not necessary (that's one of the reasons for the "care-free entry" with the moveable wings).

Edward Wright wrote:

Oh, bog. Here we go again.

First of all, I don't know of any sailplane, ultralight, or (nonmilitary) aerobatic plane that has an escape system. I'm pretty sure there are none.

Secondly, the reason military jets have ejection seats is NOT so designers can avoid putting in redundant systems. Safety are reliability are VERY important in military aircraft design. Ejection seats are not a substitute for good design but a last resort when design and redundancy fail, often as a result of circumstances beyond a designer's control (such as weather or being hit by a missile). A good fraction of all pilots who "successfully" eject will end up with broken backs or other serious injuries, so no one will ever knowingly accept an aircraft that is unreliable just because it has an ejection seat.

That is in marked contrast to the Ares design philosophy, where the Chief Engineer publicly proclaims that reliability doesn't matter as long as they have an escape system.


Edward Wright wrote:

Well, of course. Can you think of a better justification for Apollo on Steroids? :-)

Redesigning every comm sat to launch on a solid rocket motor is obviously a great idea. You just don't realize it because you don't have Mark's educational background. :-)

What "additional upmass" is that?

If NASA spends $20 billion to develop Ares V, they will be able to afford fewer launches and have less upmass than if they use existing systems.

Mike Borgelt wrote:

Edward Wright:"First of all, I don't know of any sailplane, ultralight, or (nonmilitary) aerobatic plane that has an escape system. I'm pretty sure there are none."

You are absolutely wrong on this point. There is one Russian built aerobatic aircraft with an optional lightweight ejection seat. Most of the pilots of other such aircraft and sailplane pilots wear personal parachutes which surely qualify as escape systems. In the ultralight world, ballistic recovery parachutes which lower the whole aircraft to the ground are common. There is considerable effort being expended in the sailplane world on assistance for the pilot to get out of the cockpit(inflatable cushions) and whole aircraft parachutes. These are already commercially available.

In Rand's own words about SS2 "It's Virgin/Burt's intent to make it sufficiently reliable that it's not necessary (that's one of the reasons for the "care-free entry" with the moveable wings)."

Which was my point.

As for fighters and bombers, as you correctly point out it is being hit by a missile that can make them unreliable but given the number of peacetime ejections due to systems failures I think you'll find they aren't as safe and reliable as jet airliners.

Only slightly off topic:
I once stood around with group of sailplane pilots at a contest. There were seven pilots including me. As the topic of conversation turned to parachutes I realised I was the only one who hadn't bailed out of a sailplane.

Paul,
To be fair, I don't think Mark has any financial ties to the success of Ares-I. His cluelessness isn't bought, it comes standard.

Mike Puckett wrote:

One of the reason combat aircraft have ejection seats is because second parties at times actively seek to degrade the reliability of those systems thru the high velocity introduction of various metallic objects.

Edward Wright wrote:

I have seen quite a few Sukhoi aerobatic planes. None of them had that option. You're referring to the SKS-94, which I believe is actually a Zvezda extraction seat, not an ejection seat. I think that's the same seat for racing planes a few years ago. I'm not aware of anyone who actually bought one.

Most of the pilots of other such aircraft and sailplane pilots wear personal parachutes which surely qualify as escape systems.

Only in the most quibbling sense. The difference between an energetic escape system and stepping out of a sailplane at around 100 knots is like night and day. You might as well compare it to the fire exit in a movie theater.

I once stood around with group of sailplane pilots at a contest. There were seven pilots including me. As the topic of conversation turned to parachutes I realised I was the only one who hadn't bailed out of a sailplane.

And you believed them? Pilots love to tell "hangar stories," but if sailplane pilots bailed out that often there would be sailplane accidents in the news every day. (It's a pretty safe bet a glider is going to crash if the pilot bails out.)

The NTSB reports only 72 glider accidents in the two years, most of which seem to be landing accidents and only one of which mentions a pilot bailing out. If a glider pilot bails out every couple of years, it is unlikely seven of them happened to be standing around talking to you at the airport.

Getting back to the subject, can you point out any sailplane or aerobatic airplane designers who made Griffin-like statements that reliability didn't matter as long as the airplane had an ejection seat?

Michael Kent wrote:

To expand on what Jon wrote above...

According to trade press sources, the Delta IV medium cost about $2.0 billion to develop, all of which was Boeing's money. They developed the Common Booster Core, the RS-68 engine, integrated the medium vehicle, built the factory in Decatur, built the launch complexes and Horizontal Integration Facilities at Canaveral and Vandenberg, and paid for the Delta Mariner barge to tote everything around on with that money. They got a $500 million subsidy from the Air Force to develop the Delta IV Heavy, a vehicle Boeing thought there was no commercial market for.

Things have changed somewhat since the first flight in that the Air Force now subsidizes both EELVs' annual fixed costs.

So the Delta IV medium is almost entirely a commercial vehicle paid for by Boeing shareholders, not American taxpayers -- a very different beast than the Ares I.

Yes I believed them. I knew them all and the circumstances of their bailouts. They were my customers and fellow competitors. This was Australia so the NTSB won't have the details although one bailout was in France.

To get back on track, if the system/operation is sufficiently reliable it becomes a fair bet with your life to fly without an escape system as is done every day in aviation. It took aviation a fair while to get to this point though.

Mike, don't worry about Ed. He probably hasn't visited Australia thus it doesn't exist. I checked, the Sukhoi Company sells all its aerobatic planes with either a parachute or ejection seat.

ATK has to be completely nuts to think Ares I has a commercial market.
Also on Ares I a payload with a mass of 56,000lbs must be able to perform orbital injection on it's own as Ares I lease it's payload in a 160 by -80 KM orbit yes that right the perigee is 80 KM under the earths surface.
As for reliability the Delta IV and Falcon 9 would be far more reliable.
F9 could prove to be a nearly guaranteed ride up for a sat because of engine out capability.
