Everything you need to know about we managed to glean some interesting.
[ad_1]Ars: You’re flying Artemis III without an ICPS upper stage because you don’t need the performance to reach low-Earth orbit. But you do need a second stage simulator. What’s the status of that?
Parsons: That, to me, is really cool. It’s called a spacer, and we already have the design done. Metal is already being bump-formed at United Launch Alliance, and then we’re going to weld it in-house at Marshall Space Flight Center. We expect it to show up at Kennedy Space Center no later than December, and then we’ll stack Orion on top of that. We’re in really good shape with that, and I’m pretty psyched with the progress.
Ars: So it sounds like the rocket and Orion should be good to go by mid-2027. Let’s talk about the other parts, the two lunar landers and their launch vehicles. Starting with Blue Origin, you called the prototype lander they’re flying for Artemis III a “lander test article” during your remarks today. What does that mean, exactly?
Parsons: It’s in between Mk 1 and Mk 2. It’s the same lunar crew module, which is really the most important aspect—same avionics, same flight software, so we’re going to get all of that component testing done. This will be the first production article of the lunar crew module, so we’re also going to have the ECLSS system (environmental control and life support).
The primary differences between this test article and the final lander will be the BE-7 engines, so you’re not going to have cryogenics on this test. What we’re going to use is storable propellants and a reaction control system because they don’t need the big thrust that’s needed to go to and from the Moon. That also gives us some time to really dial in what we call the dual-launch campaign. That’s going to be something to really highly choreograph as we go into the Artemis IV missions and beyond.

Ars: Can the Blue Origin lander for Artemis III be launched on the existing 7×2 variant of the New Glenn rocket?
Parsons: Yes.
Ars: You and other NASA officials expressed a lot of confidence in New Glenn being ready to launch this vehicle next year, even after the pad explosion a couple of weeks ago. Is there a decision point at which you have to make a go-or-no-go call on whether to fly the Artemis III test lander on New Glenn or to consider other rockets?
Parsons: So is there a decision point…
Ars: Like if you get to October or November of this year, and Blue Origin’s launch pads for New Glenn are nowhere near ready.
Parsons: I think you’ve heard from Dave Limp, CEO of Blue Origin, and Jeff Bezos, and they are all in. The other thing to take into account is they had already started their second pad, so they’re about a year into that development timeframe. It’s going to be a dual path. They’re really getting in and clearing out SLC-36 right now, and a lot of the key hardware is in really good shape.
