TIL Artemis uses $3600/pound grease!

https://santiemidwest.com/castrol-braycote-micronic-600-ef-1-lb-size/?sku=1577CC&gad_source=1&gad_campaignid=1838565790&gbraid=0AAAAAD1smnDrLSKWT7LRiYrnJNDuWIbPk&gclid=Cj0KCQjwkYLPBhC3ARIsAIyHi3RWRwzeXhiYuECNKV4ie-gMZJZJJN5-2OuoM6SYqLieAC2C5fdchk4aAocNEALw_wcB

I needed to go to Castrol's website to get some information and this popped up: "Chosen by NASA: We're proud to support the Artemis Programme with our space-grade lubricant, Castrol Braycote."

So I gotta know: what's the deal with this stuff? I found someone who sells it, although I suspect you don't get next-day shipping. This is what they say...

Braycote Micronic 601 EF is designed to operate in the presence of rocket fuels, oxidizers and high vacuum. It is frequently used in space applications including the Space Shuttle and satellites. It should also be considered in any application where a hostile chemical or extreme environmental conditions would preclude the use of an ordinary grease. Typical applications include ball and roller bearings, gears, and as an assembly lubricant for O-rings and elastomers. Perfluorinated greases, such as, this product, exhibit excellent shelf life due to their intrinsic inertness. this Micronic product is the 'ultra clean' version of Braycote 601EF.

Price per pound: $3633.75.

Amazon sells it in four-ounce syringes for $1671.99. Their description says it's non-toxic and nonflammable, with no CFCs used during manufacture...which would make it a fine grease for many interesting applications if it wasn't $400 per ounce. The seller is the same one that is selling pound cans of it on their own website...maybe they're the only firm in America that has any?

Kegsbreath buys the old scroungy grease that squirts out of fittings when you lube your car. The blacker it is the better he likes it.

Helpful hint: If you have a car that has grease fittings, what we've all been told is to put the nozzle of the grease gun on the fitting and pump until some comes out. This is not what you want to do for longest bearing life. Instead, count the number of pumps it takes grease to come out of the fitting - then pump that number again. If it takes 15 pumps for grease to come out, pump a total of 30 times. Just pumping 15 times refills the grease reservoir but it leaves the old grease in the bearing. Pumping 30 times completely changes it.

Then again, it may be flying off the shelves.

Castrol only got the contract because they were so low.

You're definitely right about the competition thing...very few companies would even want to try to make lubricant that stays slick at the temperature of liquid hydrogen.

The reason your ink is so expensive is you're buying new heads every time you buy ink. At work I buy wide-format ink that's way cheaper per ml than what you use in your desktop printer.
