Is there anything of note at this supposed second site?Could it be quicker to build LC-36B rather than repair LC-36A? Or is to too early to say?
Are we pretending those are real things, considering their supposed schedules?NASA’s Artemis program and Moon Base
It's not like they're going to launch any of the flight hardware any time soon. So that's just another line item, and probably not the long pole, timing-wise.damage to the hardware inside. Seems like that would make a bad situation worse.
How critical is this really though? Mark 1 is supposed to have a payload of 3 tonnes to the surface, is boiloff so bad that it can't do 1 tonne down without top off? I get that the boiloff is going to hit hydrogen disproportionately, you may want to short load the LOX to compensate, but again when you only need a fraction of the performance seems possible. It may not be ideal, but if the goal is to keep Artemis moving and none of the payloads require its full capabilities, there ought to be some workaround possible.There’s a problem. The Mark 1 lander is powered by the BE-7 engine, which runs on liquid hydrogen and liquid oxygen. According to a source, the lander, in the hours after launch, requires “backfilling” from the New Glenn upper stage to top off propellants.
This all but rules out Falcon Heavy, which has an upper stage that uses kerosene propellant rather than hydrogen.
The usable payload to the Lunar surface is literally all in the margins. It goes from whatever you're happy with on full tanks to negative in no seconds flat.How critical is this really though.

"Aspirational goals" as we dub things in our business post-modernist slang, for things we know will never happen on time or as imagined.Are we pretending those are real things, considering their supposed schedules?
There is construction going on about 500m north of the active pad. On Google Earth, the last imagery date is 29/12/2025 and looks like earthworks are still underway. Major concrete works don't look like they have started yet, that is probably a showstopper for getting the second pad up and running instead of repairing the first one.Is there anything of note at this supposed second site?
All I could find was a reported application to build another pad.
Even as of last night there was strong indication that everything inside is fine.I’ll be interested in hearing the assessment of the HIF. There was clear external damage to the structure and rumors were flying about direct damage to the hardware inside. Seems like that would make a bad situation worse.
As it is, Blue Moon mk.1 is at the limit of TLI for Falcon Heavy. One wonders if there's enough height in the fairing to include a Blue Ring behind the BM1. In which case, you might save some of the departure prop for landing and have enough left after boiloff.How critical is this really though?

They have at least 2 more NG1 already built. You would only drop them, if the cost of having a tower that supports only 9x4 is way cheaper than having a tower that supports both. Also, you need to take into account how fast you can finish the 9x4 design and built it.7x2 was struggling to hit its 45-tonne payload goal. With a forced >15 month pause, Blue Origin might as well retire 7x2 and focus on 9x4. That way when they come back they'll at least have a more capable rocket. I know it sounds cold but some big decisions are going to be contemplated in the next few days.
SpaceX also executes static fires at their launch pads. That's literally how they lost the AMOS-6 rocket.It makes the SpaceX separate test facility look like a very good idea. They blew that test site up once and had to risk testing at the launch pad, but they only do that in an emergency (at least for the second stage). I would think separate testing and launching facilities will become a best practice for all launch companies soon.
One also has to factor in the time and cost of design changes to New Glenn to mitigate this failure.They have at least 2 more NG1 already built.

Also, you need to take into account how fast you can finish the 9x4 design and built it.
With 7x2 you could do a launch the week after the tower is ready. Even if you are only launching 30t.
I think that further in the future it would be better for BO to have a 9x2 option instead of the 7x2 (BE-3U engines aren't cheap). But I don't see 9x4 being ready in the next 18 months.
In the article, it was mentioned that for these very large rockets, the facilities are much more expensive. $100 million here, $100 million there, you know, and pretty soon it's real money even to Bezos.It makes the SpaceX separate test facility look like a very good idea.

And given that a Falcon 9 launched today, it can't be all that bad.Well, there was a debate over how big the danger space is when a methane-fueled rocket explodes (mostly in terms of how the Starship launch pad at the Cape would interfere with other activities there). I guess we have some real-world data now.
That was one of my first thoughts when I saw the size of the mushroom cloud in Scott Manley's review. This seemed to be an explosion rather than a deflagration. It's a shame to test it this way, though.Well, there was a debate over how big the danger space is when a methane-fueled rocket explodes (mostly in terms of how the Starship launch pad at the Cape would interfere with other activities there).

Mark 1 doesn't go to TLI, it starts from LEO and does its own TLI.As it is, Blue Moon mk.1 is at the limit of TLI for Falcon Heavy.

While this might not be a "bright side" for others, and with full understanding of the implications this has for US space programs, I did have the errant thought that mushroom clouds over Florida looked kind of cool in a Dr. Strangelove sort of way. Especially seeing those lightning towers wiggling around as they were enveloped in flame.Wondered about many of these questions! As always thanks for providing the answers and keepin us updated on the space industry!
That explosion was crazy...
