Someone compiled all of their workmanship standards into one huge PDF.

Judging from few cafeterias I have been two, “good enough” varies between centers.

NASA used the same scale for grading Nazi scientists

Should have just kept the nerds in prison camps like the Soviets tbh

Anyone following Shelby’s Larceny System already knows what passes for “ good enough ” in government circles:

After discussing this and other details, Lueders then rather casually let it slip that “NASA also aligned the development costs for the SLS and Exploration Ground Systems programs through Artemis I and established new cost commitments.” The new development cost for SLS rocket is $9.1 billion, she said, and its budget for the initial ground systems to support the mission is now $2.4 billion.

This represents a 33-percent increase for the rocket since 2017 , when a “re-plan” of program estimated development costs for the rocket, including a single test flight, would be $7.17 billion. (This was detailed in a US Government Accountability Office report published nearly a year ago.) This figure represents only direct development costs. NASA has received more than $20 billion from Congress since 2011 for SLS development and related activities. 

One of the commentors on Ars did the math :

Bad napkin math:

~$8.5 billion: Cost of a Nimitz class aircraft carrier.

~100,000 tons: Approximate displacement of a Nimitz.

~$2-10 billion: Estimated development cost of Starship/Superheavy launch system.

~$2-10 million: Aspirational cost of a Starship/Superheavy launch.

~100-150 tons: Ballpark figure for Starship/Superheavy payload to LEO in fully reusable mode.

667-1,000: Number of Starship/Superheavy launches needed to loft 100,000 tons to LEO. (depending on that payload capacity being 100-150 tons, ignoring volume constraints)

Price tag to develop the SS/SH system from scratch, build an aircraft carrier , and launch it into orbit (in pieces, admittedly): $11.8-$28.5 billion, or potentially as little as half of the SLS budget since 2011.

Figures not included:

- Price of the Orion capsule program? I assume the $20 billion that Eric mentioned was only for SLS, SLS ground service equipment, and other SLS stuff although Orion costs weren’t explicitly mentioned in the article.

- Price of all the stuff that goes in the aircraft carrier, because I believe 100,000 tons is the fully loaded displacement, not the empty displacement.

- SpaceX ground service facilities and cost to actually manufacture the unknown number of reusable SS/SH for this task.

Your Germans

The Germans she told you not to worry about

Launch that thing into space and make it maneuverable, and you have the makings of a live-action anime

Nah, see, you get two o f them, then you connect them to a remodeled alien ship ...

Oh wow ! Every once in a while I see somebody share a link to a page on wire splicing, but I didn’t realize it was just an excerpt of a much bigger document . Neat!
