Elon Musk says SpaceX to launch Mars rocket prototype
SpaceX is about to perform its most ambitious test-launch yet of a shiny Mars rocket prototype.
The prototype is built out of stainless steel and is equipped with one of SpaceX's next-generation Raptor rocket engines.
Company founder Elon Musk named the roughly six-story-tall rocket ship "Starhopper," says Business Insider.
Engineers hope to take the vehicle up to about 65 feet on Tuesday.
Musk tweeted that there will be live-streaming video of the launch.
