By subtly engineering its catalytic site, they enabled the enzyme to carry out the MHAT reaction with remarkable ...

An additional factor also leads to overheating. The 28 reaction control system thrusters are located in four doghouse-shaped propulsion pods around the circumference of the service module.

NASA engineers have successfully tested a new breed of reaction control engine and propulsion system. Aimed at furthering NASA’s space exploration goals, the tests helped investigate the ...

Five of the reaction control system thrusters failed on the service module, but the duo was able to get four of the thrusters firing again after conducting hot-fire tests.

Each engine delivered 440 Newtons of thrust and all 16 Reaction Control System (RCS) thrusters. Every engine offered 100 Newtons of thrust, and both steady-state and pulsed modes were tested.
