Startup That Aims To 3D-Print Rockets Says It's Fully Funded For Its First Commercial Missions

Aerospace startup Relativity Space -- the company that aims to launch the first fully 3D-printed rocket to orbit -- says it has raised all of the money it needs to launch its first mission and then enter commercial operations as early as 2021. After raising $140 million in its latest funding round, Relativity says its total funding now equals $185 million, which is enough money to carry the company through its first flights over the next couple of years. The Verge reports: Started by former engineers at Blue Origin and SpaceX, Relativity has grand ambitions to create all of its vehicles -- from the engines to the fuselage -- using 3D printing almost exclusively. The goal is to overhaul how rockets have been built for the last 50 years by taking people out of the manufacturing process and automating almost everything. By building rockets this way, Relativity claims it can drastically cut down costs by requiring fewer parts per rocket. Eventually, the company hopes to replicate this 3D-printing process on another world, like Mars, creating a rocket that can take off from the planet and return to Earth. Right now, the company is focusing on its first rocket, the Terran 1, a small- to medium-sized vehicle being built with Relativity's specialized Stargate 3D printers in Los Angeles. Relativity says these updated printers could eventually create a Terran 1 rocket in less than 60 days from raw material. "Those are actually twice the print size of the prior version, and we have several of those already up and operational," says [Relativity Space CEO Tim Ellis] of the updated printers. Designed to stand about 100 feet tall, the Terran 1 rocket will be able to carry up to 2,755 pounds (1,250 kilograms) of payload, which is just 6 percent of the capacity of SpaceX's Falcon 9 rocket. However, the company says it has increased the size of the vehicle's nose cone, or payload fairing, making it able to hold twice the volume as originally planned.
