Martian Monday: New NASA Rocket Engine Test A Success

Humanity is becoming ever-more ready for the Red Planet, and now, NASA has taken yet another small step that could end up profoundly propelling mankind...

The twelve-million-horsepower Aerojet Rocketdyne RS-25 rocket engine was tested last Thursday at the Stennis Spaceflight Center in Mississippi, a NASA report confirmed.  The engine, according to Space Launch Systems spokesman Martin Burkey, "makes a modern race car or jet engine look like a wind-up toy."

The RS-25 burned for nine minutes, with its four core engines consuming the equivalent of nine swimming pools' worth of fuel.

The engine, while requiring minimal weight for optimum speed, must also endure the extreme temperatures inherent to the rigors of spaceflight.  The void of space could find the engine dealing with temperatures of -400 degrees Fahrenheit, while the combustion during launch could put the heat at well over 6,000 degrees.

"The bottom line is that the RS-25 produces 512,000 pounds of thrust. That’s more than 12 million horsepower. That’s enough to push 10 giant aircraft carriers around the ocean at nearly 25 mph," Burkey explained.

Best of all, the engine is one of several that remain from the heyday of the Space Shuttle program, and a large enough inventory of such engines remain for four flights, with no need for extensive reinvention or expensive infrastructural investments. Five upgrades have been made to the RS-25 since its inception, and at least one further augmentation will likely follow before the rocket has transformed into a single-use engine of extraordinary thrust (moving 130 metric tons, or 143 tons!)

The RS-25 has currently completed six of seven live-fire tests, and will be next tested in full force, with four of the RS-25s firing in tandem.  When combined with two solid-fuel boosters and a fuel tank, the entire craft is known as the Space Launch System, and along with an Orion space capsule, it could be our ticket to pioneering towards a new planet.


Fire it up!  The continued tests of RS-25 have been a spectacular success.
Onward with Orion!
