The question is already being asked on social media: Was today’s launch a success? The short answer is YES! The longer answer is the subject of today’s post. Before I dive into that, some quick background given that the internet (particularly social media) is full of bots.
I covered aviation, space, science, and related topics for several years. Under Dave Dooling’s administration, I served as Correspondent-at-Large for SpaceWorld (article about as it is long gone) magazine for a few years, and worked a bit in radio. Hit the Readers’s Guide to Periodic Literature (hope it’s still around) for the byline C. Blake Powers. I later worked at the USAF Arnold Engineering Development Center (now Complex) and was there for the J5 incident. Said complex was/is the Free World’s most comprehensive testing site and could test at simulated altitude in a variety of the test chambers. After getting my Master’s, I went to work for Essex Corporation, where we were a subcontractor providing support to Spacelab through TBE. Among other things helped write a number of mission brochures, reports, and got to do a LOT of neat things. Left for a while, got asked to go to work for a company called CST working as a contractor for the Space Product Development Program (Commercial Space) where I was Director of Outreach and Education. Even was on a panel with Elon as I’ve noted a time or two before. As also noted previously, my thesis was The Soviet Watchers: A Directory of Western Observers of Soviet Space Efforts and it should still be available at the UTK library. Also, earned a pilot’s license, got to go through altitude training (and ejection training) and certification, and a few other things. So, not just an anonymous internet rando and things can be checked out fairly easily.
So, today was a success. The people at SpaceX really weren’t joking when they said if it cleared the tower it was a success. Given the number of rockets and rocket systems over the years that have taken out the launch pad on their first test, it really is a good thing. The first time you stack it all together and light the candle, anything can happen.
They got it off the pad. They got it up to a pretty good altitude. Then it went south. Happens. In fact, it’s a good thing when it happens during testing.
SpaceX is doing what should have been done by many others: they test. They test to destruction. The Starships that exploded in ground testing? Good thing. Lots and lots of data. They were not failures, each one enabled the next to be improved. Certain agencies and many companies don’t want to test to that extent, as they are convinced the public sees such as a failure when it is not so. Yes, I know there are idiots that do feel that way, but they have no clue about reality as a general rule.
Today, they got more data on the assembled vehicle and how it performed both on the pad and in use. They got reams of data on fueling and related issues. They got reams of data on each engine and how they performed together. They got reams and reams of data on major and minor systems. Data on the micro and the macro that you really can’t get except in flight. Ground-based testing can test individual components or systems. You can’t test something that large except in flight.
So, you do all the ground testing you can. You make each part as good as you can with that data. Then you integrate and launch to test. You do so knowing you are probably going to lose some of the test vehicles. As I said before, it is a good thing.
Had today’s launch gone perfectly and everything worked exactly as predicted, I would have been amazed, delighted, and concerned. On something this complex, if you have a perfect flight on your first test flight, smart people tend to ask if you really got everything perfect; or, if you just got lucky and missed something that is going to bite you in the ass later as the odds change? The latter is the safe bet, by the way.
Just a guess, but it looks like they had several issues. Several of the engines failed early. The complex separation maneuver did not go to plan. Obviously the stage separation systems did not work to plan. We will learn more in the days ahead, as it takes time to go through the massive trove of data from a test like this.
And that’s the point. That’s what makes today a success. The data gathered today is worth the cost of losing five Starships. With that data, good analysis, and good engineering, you redesign, refine, retool, and relaunch. Then you take the data from that launch and do the dance over and over again. It is an iterative process and if you think they aren’t doing it Falcon and other things, I’ve got a bridge for sale, cheap. It is the smart way to do it, and Elon is a pretty smart guy who also hires a lot of smart people to work for him.
So, unlike this morning’s memory, no rye today as there was no scrub, just a good test. If it had gone perfectly, I do have some Sazerac standing by but while I wish they gotten just a bit further, I’m delighted they got as far as they did and even more delighted at the data they got. It will allow them to get further ahead faster, and we need to head for the stars.
