Engineers prepare a 3D printed turbopump for a test at NASA's Marshall Space Flight Center. The turbopump was tested at full power, pumping 600 gallons of semi-cryogenic liquid methane per minute, ...

Propulsion provider Aerojet and partner Florida Turbine Technologies (FTT) have completed preliminary design of the turbopump assembly for a new upper-stage rocket engine under consideration by the ...

Based on a request from the US Air Force, a new Upper Stage engine – to ultimately replace the RL-10 used by the Atlas V and Delta IV – has made another advance, as Aerojet – one of the competitors to ...

There are plenty of rocket experimenters toying with various liquid-fueled contraptions at the moment, and [Sciencish] is one of them. He grew tired of using air-pressurized fuel delivery systems in ...

NASA has previously tested simple 3D-printed rocket components, such as combustion chambers and fuel injectors, but if the technique is to be practical, it has to cope with more complex items. Case in ...

After spending roughly eleven months independently investigating Orbital ATK’s botched Antares rocket launch, NASA has officially released an 11-page report detailing its findings on the spacecraft’s ...
