Another Artemis Delay

I wish that every time some politician (and Bill Nelson is definitely one of those) says that “Safety is the highest priority,” someone would ask them, “What is safe enough? When are you going to fly? How safe will it be then? If safety is the highest priority, why would you ever fly? Not flying is the only way to make safety the highest priority.”

ULA

Can it get its mojo back?

I think that partially, even largely depends on whether it can get a better owner than the current ones.

[Update a while later]

I have more thoughts over at X.

[This is a good history from @SciGuySpace, but there’s a word missing in it: Starship. Tory’s problem is that he thinks that he’s competing against Falcon, but Elon is going to obsolesce Falcon ASAP. How will Vulcan or New Glenn compete against a fully reusable heavy lifter?

The thing about Elon is that he never faces the Innovator’s Dilemma. His first instinct is to obsolesce his own product line before a competitor can. Anyone who wants to seriously compete against SpaceX has to compete against his future plans, not his current business.

If space launch was just a business for Elon, he’d be as complacent as any other businessman in his position, but it’s not a business; it’s a passion, and he wants to get thousands of people to Mars. So he’s going to continue to out-innovate the competition.

Imagine a world in which SH/SS is flying daily (or more often) on regularly scheduled trips to ELEO at a cost of tens of dollars a pound. Propellant would be cheap enough to deliver a payload to anywhere in cislunar space for much less than the cost of a traditional launch. That is what ULA and BO are going to have to compete with if they want to stay in the launch business.

I know, “But there’s not enough demand for that level of launch activity!” Believe me, at those prices, we will finally see the kind of price-demand elasticity that will drive it through the roof. People will be doing things dreamt of for decades, held back only by launch costs.

So good luck to ULA (and BO) on their upcoming maiden flights this year, but I don’t predict a long future for them. Not to mention SLS… 

I feel like I should write a book about this.

[Monday-morning update]

ULA had a successful maiden flight, but there’s an anomaly with Peregrine.

AIAA SciTech

As you can see in the left sidebar, I’m planning to attend next month in Orlando. They used to be in San Diego, and I haven’t been to one since before the pandemic. ASCEND was a huge upgrade over their previous annual space conference, and I’m curious to see how much SciTech has changed in the past few years.

As you can see from the program, it has a wide variety of papers on not just space (my primary interest, as always), but aviation as well. The number of simultaneous topics is overwhelming (as it has been in the past), but I’ll be interested primarily in sessions on space resources, space assembly and servicing, life support for larger facilities, nuclear propulsion (both electric and thermal), human logistics in space and space medicine, advances in additive manufacturing, AI applications and, of course space policy. I’ll also be discussing my own participation in the Cislunar Ecosystem Task Force, which was first announced at this event a year ago.

I don’t know if there will be any news broken there, but if there is, I’ll be blogging about it here. I won’t be attending Friday, because I have to be in DC. But I will be there Monday through Thursday, and I hope I’ll see some of you there.
