An astronaut leaves the Space Shuttle and space walks 20 yards away from it. The temperature surrounding him/her, independent of his/her space suit or body temperatures is what???

Are you sure it's alumina? Mullite is ivory in color.

Again. An astronaut steps out of the Shuttle. The temperature of space two feet in front of them is what??

You're saying that stronauts are space-walking around in 4K areas?

You walk outside the shuttle and put a thermometer in space. What does it read?

You braze titanium to alumina by placing any Ag-Cu braze alloy in between and heating in argon or vacuum to approx. 900C.

What is the typical temperature outside the Space Shuttle when it is in orbit?

Can anyone please give me examples of components and systems that NASA uses titanium alloys for?

Graphites vary widely in thermal conductivity. I believe Poco Graphite has a high conductivity foam.

Can anyone please explain to me the electrowinning process? Can it be used to manufacture parts?

I like CusterWilson's manner of engineering investigation.

I heard that there is a particular non-woven carbon felt which is carbon infiltrated to make aircraft brakes. Does anyone know who makes the felt?

Can anyone please explain to me how pinning centers work in superconductors?

Does anyone have fracture toughness values for carbon-carbon composite?
