The launch of the world’s first 3D-printed rocket was ultimately scrubbed after several tries today, marking a new setback for the private owner of an innovative spacecraft billed as being less costly to produce and fly.
Engines had begun igniting on the unmanned Terran 1 rocket, built by California aerospace startup Relativity Space, when an “automation” issue caused the company to abort takeoff for the second time in less than a week.
A little later, the company tried again to launch the spacecraft from Florida’s Cape Canaveral but had to abort due to pressure issues in the rocket’s second stage, the company later tweeted.
“The team went HARD today and we intend to do so during our next attempt. More to come on the new launch date,” Relativity said.
At one point during the three-hour launch window, which began at 6pm Irish time, the countdown was put on hold when a private boat violated a danger zone.
Once it does take off, Terran 1 is set to reach low Earth orbit eight minutes after blastoff on a voyage intended to gather data and demonstrate that it can withstand the rigors of liftoff and space flight.
If the rocket manages to attain low Earth orbit, it will be the first privately funded vehicle using methane fuel to do so on its first try, according to Relativity.
Terran 1 is not carrying a payload for its first flight, but the rocket will eventually be capable of putting up to 1,250kg into low Earth orbit.
The rocket is 33.5 metres tall with a diameter of 2.2m and 85% of its mass is 3D printed with metal alloys, including the engines.
It is the largest ever 3D printed object, according to the Long Beach-based company whose goal is to produce a rocket that is 95% 3D printed.
Terran 1 is powered by Aeon engines using liquid oxygen and liquid natural gas – the “propellants of the future,” according to Relativity, capable of eventually fueling a voyage to Mars.
Vulcan rockets being developed by United Launch Alliance and SpaceX’s Starship use the same fuel.
Terran 1 has nine 3D printed Aeon 1 engines on its first stage and one 3D printed Aeon Vacuum engine on its second stage.
Built in 60 days
Relativity is also building a larger rocket, Terran R, capable of putting a payload of 20,000kg into low Earth orbit.
The first launch of a Terran R, which is designed to be fully reusable, is scheduled for next year from Cape Canaveral.
A satellite operator can wait for years for a spot on an Arianespace or SpaceX rocket, and Relativity Space hopes to accelerate the timeline with its 3D printed rockets.
“Long-term, a major benefit of 3D printing is the ability to more rapidly democratise space due to the incredible cost effectiveness, radical flexibility and customisation,” the company said.
Relativity said its 3D printed rockets use 100 times fewer parts than a traditional rocket and a Terran 1 and a Terran R can be built from raw materials in just 60 days.
Relativity has already signed commercial launch contracts worth $1.65 billion, mostly for the Terran R, according to CEO Tim Ellis, who cofounded the company in 2015.
“Medium-heavy lift is clearly where the biggest market opportunity is for the remaining decade, with a massive launch shortage in this payload class,” Mr Ellis tweeted.
