Comment on NASA Completes Mighty Solid Rocket Boosters for Artemis 2 by Jeff Wright
I’d prefer the SLS cores go to Interstellar Probe paid for by killing Lunar Starship.
I don’t want one dime of my taxes going to the New Spaz movement.

Comment on NASA Completes Mighty Solid Rocket Boosters for Artemis 2 by Rodney Price
In reply to Alex Longo.
Hi Alex, Perhaps the “clean room” around the SRB joints is more for temperature control than dust elimination.
The cost of flying Artemis 2 : .. Could be huge. No one has any incentive to do it quickly or cheaply. Orion, SLS & EGS are costing ~ $ 3 Bn/yr ? and it’ll be at least 12 months until Artemis 2 launches, but could be over 24 months.
“Stack” and “launch” sounds cheap but there is a huge amount of testing during and after assembly, with an army of thousands on standby. Artemis 2 won’t achieve anything significant, but puts astronaut’s lives at risk.
Some would argue that if NASA continue and launch Artemis 2, they should also do Artemis 3 (to achieve the lunar landing) but that would be another huge expense for a publicity stunt that doesn’t help sustainable long term operations on the moon.
Lunar Gateway might as well be cancelled as well. It was never needed for lunar ops, just a practice for travel to Mars, and another reason to build and
The armies of people working on Gateway, Orion, SLS & EGS could develop payloads and spacecraft for Falcon Heavy, Starship and New Glenn to launch.
Best wishes to all – especially in Ukraine.

In reply to Rodney Price.
Hi Rodney,
Thanks for your interest in these Artemis stories. I feel like I have seen your name in the article comments a few times now.
I do not know the exact reason why they need to protect the booster from small contaminants, but I cannot see any other reason to go through all the effort of building a cleanroom the boosters every time they integrate two segments. My guess is that they are worried about the field joints between the segments, which are more vulnerable than the rest of the booster and critical to mission success (as tragically illustrated by Challenger). I put a brief description of this type of joint, as well as a diagram, into this article:
https://www.americaspace.com/2024/11/26/artemis-2-stacking-begins-as-heat-shield-decision-looms/
NASA has not disclosed the remaining cost of flying Artemis 2, but I would estimate that it is in the low hundreds of millions of dollars rather than the billions. All of the hardware is complete. Even Orion, which was the pacing item for two years, just needs its solar array wings. They just need to pay for the labor required to stack the components and launch. Safely disposing of all this hardware (especially the SRBs, which are full of explosive and caustic solid propellant) would probably cost as much as flying it. Regardless of how Isaacman et al. decide to move forward with Artemis, I would strongly encourage them to go ahead with this flight.
The FTS sounds dangerous, but without the batteries which power it, it is no more dangerous than the propellant inside the SRBs. It needs an electric current to ignite. Like any other plastic explosive, it is relatively safe to handle, so long as you know what you are doing. Installing it separately just saves time and money. Shortly before they roll out for launch, they will arm the FTS by installing the batteries.
Best regards,
Alex

Comment on NASA Completes Mighty Solid Rocket Boosters for Artemis 2 by Rodney Price
Strange that such huge booster segments could be jeopardised by dust or even a strand of human hair.
” The cost of flying the mission, in both dollars and man-hours, is relatively low,” – Only a few $ billion more then ?
Interesting that they install the FTS explosives before slotting core between boosters.

Blue Origin Achieves Orbit With New Glenn
In September of 2013, the simmering rivalry between entrepreneurs Jeff Bezos and Elon Musk reached a fever pitch. NASA’s historic Launch Complex 39A, the launch pad for Apollo 11, was no longer needed, and the agency decided to transfer it to a commercial firm. Musk’s SpaceX and Bezos’ Blue Origin both submitted proposals to renovate the hallowed site. Musk was […]
