This video shows a test with at 3-D printed turbopump made with 45 percent fewer parts than traditionally manufactured rocket fuel pumps. The pump’s turbine spins at more than 36,000 revolutions per minute. As the turbopump moves 600 gallons of liquid methane per minute, frost forms on the outside because the fuel is super-cooled to -255 degrees Fahrenheit. Methane burns out the flame pipe at the end of the test area. #mars | @BeautyOfTheUniverse | #BeautyOfTheUniverse
