Barzon

ooh

I've heard that 3 of the 13 cubesats that were due to launch on Artemis 1 have missed the deadline and now won't be launching on A1. The cubesats that won't be launching anymore are CU-E3, Lunar Flashlight, and CisLunar Explorers. I'd interpret this as meaning that Orion will be mated to the flight OSA relatively soon.

yea that makes sense and I agree

all the NASA peeps I know are very happy with this news, Plus afaik this was how it was for years until it was changed at some point after CxP got cancelled. also yeaaa I'm back kinda hope yall been doing ok

aight

Hi uh I know it says this is one time only but I'd really rather move away from the Barzon name and if it could be changed to kerb that would be great?

lmao why'd they scrap it

Nope, I've never noticed before.

whaaat when did you become part of the KSP team?

RS-25E will run at 113% iirc.

Everything I've heard is that Bill is very supportive of both commercial space and SLS/Orion.

I believe the grapple target is present because Canadarm3 is too short to reach external payloads on Dragon XL from Gateway, so has to move itself onto Dragon to reach the payloads.

wait what MMSEV

Absolutely stunning!

Per Anatoly Zak, Dragon XL is 13t.

Are you sure? Everything I've heard is that Starship expendable can't get anything futher than GTO without refuelling? Although yes a kickstage could probably do the job.

Yea I agree, the 8 month cadence is based off the time needed to build a new core stage, but IDK how the time needed for the rest of the vehicle to be constructed factors in. and expendable starship still needs refuelling which... I'm not that confident in, not at such a large scale.

Indeed. It certainly depends on where the loads are low enough to allow practical (well, as practical as you can get with a rocket that currently can only be launched every 8 months) usage for lower mass spacecraft. Hopefully the loads would be low enough for Europa Lander to be launched on SLS, as I really can't see Starship being ready to launch deep space probes by whenever Europa Lander needs to launch.

Important context in a subsequent tweet...

@rogerwang86would you consider adding an alternate engine section like the one in the below image? This was considered near the end of the Constellation program as a solution to the heating issues they were having.

That's the JSC mockup. (I can't figure out how to embed images from twitter, so I've just posted the tweet)

It's not that big without the drop tanks, if the JSC design is accurate - which I presume it would be.

oh god this is incredible
