The offset would be calculated in the Mission Editor when the user defines the T0 (in GMT), and from that I can work what MJD that is for the scenario, based on the leap seconds table. The resulting offset can easily be shown in there, so it can be used in FDO MFD if needed.

Well, Orbiter uses TDB because of the orbital mechanics and that is not going to change. We got used to treating what is displayed as UTC/GMT, but when we go deeper, there is an ~84s difference, and that makes a difference. I'm thinking the best solution is to isolate the time in SSV from...

So, this took a while to look over... I'm critiquing AI and I'll be honest, so I guess I'm toast when it takes over. :( Let's start with the bad. Some stuff is, IMO, implemented in a way that is not "sustainable" e.g., modules with PASS and BFS code? Nop, way too messy. If tomorrow I want to...

I've come to appreciate boring hotfires. Our BE-7 team recently completed a 2,500 second hotfire test at 10klbf on a development engine, setting the record for the longest-duration turbo pump-fed liquid rocket engine hotfire. This built on some of the most rigorous testing in the history of...

Holy mackerel!!! As leak rates rose, Russian officials informed NASA on Thursday, June 4, of plans to attempt physical repairs to the new leaks with a drill and a “drill stop” device to prevent drilling all the way through the module’s structure. NASA officials were deeply concerned about this...

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...

That seems to be a simplified Blue Moon Mk2 lander, apparently for A3 and A4, and looking at that it seems to maintain the same crew module, but with the smaller tanks of the Mk1 lander. (maybe they should call it Mk1.5?)

Starting with some energy, and my inability to write brief updates, I am just extremely proud of the NASA crew, our industry, and our international partners. We are getting into a rhythm here at NASA. Earlier this year, setbacks put the Artemis II rocket back in the VAB for repairs, and we...
