SpaceX has successfully tested a new rocket engine which they plan on using to bring people to Mars within the next 10 years. The rocket test was revealed on Sunday at the company’s testing facility in McGregor, Texas. CEO of SpaceX, Elon Musk, is developing the Rocket Engine Interplanetary Transport System, a spaceship with the capacity to contain a large amount of people, and states, “This vehicle is intended to carry huge numbers of people, possibly millions of tons of cargo to Mars.” Once the spaceship gets into orbit, it launches a smaller ship contained within a larger rocket, allowing it to travel further into space.

Earlier this month, SpaceX suffered a setback when one of its rockets exploded on the launch pad at Cape Canaveral. So, they began to develop an even better rocket, the Space Launch System Rocket, which will impel the Orion spacecraft on a mission to Mars; the cost of the project is about 680 billion dollars. As research develops, Musk, along with his team are hoping to attempt bringing humans into deep space within April of 2023.

Space X isn’t the only organization testing rockets engines with a mission traveling to Mars. In June, NASA test fired its Space Launch System booster rocket, expecting to use on its own mission to Mars. The next booster rocket test will be tested on Orion’s test flight to Mars in late 2018.
