Stratolaunch, the Seattle-based space venture created by Microsoft co-founder Paul Allen seven years ago, says it’s discontinuing its programs to develop a new type of rocket engine and a new line of rockets.
The company said it would continue work on the world’s largest airplane, which is designed to serve as a flying launch pad for rockets. Last week, Stratolaunch put its 385-foot-wide, twin-fuselage plane through a high-speed taxi test that many saw as a precursor for its first test flight at Mojave Air and Space Port.
“Stratolaunch is ending the development of their family of launch vehicles and rocket engine. We are streamlining operations, focusing on the aircraft and our ability to support a demonstration launch of the Northrop Grumman Pegasus XL air-launch vehicle,” the company said in an emailed statement. “We are immensely proud of what we have accomplished and look forward to first flight in 2019.”
