They sure don’t make rockets like they used to. At least, that’s what NASA thinks. In the development of its Space Launch System rocket, the space agency will be looking to the past for some inspiration.
NASA OUT OF IDEAS; LOOKS TO THE 1950’s
While NASA is making some great progress with its Space Launch System rocket, they have hit a bit of a speedbump. When it comes to the upper stage of the rocket, the agency hasn’t decided on an architecture. The upper part is used to increase payloads beyond Earth’s low orbit and into deep space. It’s an important aspect and Congress has been pressuring the agency to make a decision. After considering nine different ideas, NASA has finally decided on an engine. The RL-10 was made in the late 1950’s and first used in 1963. The liquid hydrogen/liquid oxygen fuel from the past will hopefully propel rockets of the future.
IF IT AINT BROKE…..
It seems a bit curious that anyone would consider using such an old technology for something so advanced as launching a rocket, but NASA has explained their reasoning. The chose the RL-10 for its reliability, its record of success and its convenience. Time is of the essence for construction and the RL-10 can be quickly adapted into the upper stage of this rocket. Another factor that wasn’t mentioned but can most likely be assumed, is cost. The federal government isn’t exactly shelling out billions of dollars for space travel, so if they can accomplish more with less, they will likely try to do so.
IS 3D PRINTING THE FUTURE FOR SPACE AGENCY
If NASA ever runs out of 1950’s rockets to use, they very well could look to 3D printing for their future rocket engines. A team has already developed and tested intricate engine parts that have been 3D printed so the possibility is very real. 3D printing would provide a fast and affordable way of making new parts for space vehicles. Estimates show that 3D printing uses about 45 percent fewer parts than traditional welding. Seeing as the agency is increasingly budget conscious, 3D printing will likely be commonplace.
