Here is a bit more information about the insane metrics that were achieved during this test:

During the test, the 2,000 horsepower, 1,200 gallon per minute pump was run up to 90,000 rpm, about ten times faster than a jet engine at take-off. It was also exposed to a rocket engine-type environment with temperatures of up to 6,000 Fahrenheit and as low as -400 degrees at the liquid hydrogen intake.

NASA deemed the tests a success, and is sharing its data with approved partner companies.

This is quite an accomplishment.  If the process of producing satellites and rocket engines continues to become more efficient, they will be able to launch a greater number of missions.

Comgratulations to another milestone by the innovative team who built this engine.
