WASHINGTON: The world’s first 3D printed rocket is scheduled to blast off from Florida on Saturday on the maiden flight of an innovative spacecraft billed as being less costly to produce and fly.
Liftoff of the rocket, Terran 1, had been scheduled for Wednesday at Cape Canaveral but was postponed at the last minute because of propellant temperature issues.
The new launch window for the rocket built by California aerospace startup Relativity Space to put satellites into orbit is from 1:00 p.m. to 4:00 p.m. (1800 GMT to 2100 GMT) on Saturday.
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 2,755 pounds (1,250 kilograms) into low Earth orbit.
The rocket is 110-feet (33.5 meters) tall with a diameter of 7.5 feet (2.2 meters) and 85 percent 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 percent 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.
Relativity is also building a larger rocket, Terran R, capable of putting a payload of 44,000 pounds (20,000 kgs) 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 democratize space due to the incredible cost effectiveness, radical flexibility and customization,” 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,” Ellis tweeted.

Essex man takes on charity endurance challenge for children in Gaza
- Mark Watson, 63, is undertaking a “virtual Sumud” journey from his Essex home town in Harlow to Gaza, covering 2,287 miles
LONDON: A man in England has launched a demanding charity challenge to raise funds for children affected by the war in Gaza.
Mark Watson, 63, is undertaking a “virtual Sumud” journey from his Essex home town in Harlow to Gaza, covering 2,287 miles through running, walking, swimming, cycling and rowing.
He is raising money for Medical Aid for Palestinians, a UK-based humanitarian organization providing healthcare to Palestinians in Gaza and the occupied territories.
“I have felt helpless day after day seeing images of countless children in Gaza with broken bodies and missing limbs and witnessing their unbearable suffering,” Watson said on his JustGiving page.
“I have been inspired by the courage of those who took part in the global Sumud flotilla and all of the activists who have put their lives and freedom at risk supporting the Palestinian people and so I am raising funds for Medical Aid for Palestinians.
“My challenge is to complete a virtual Sumud from Harlow, where I live, to Gaza. Running, walking, swimming, cycling and rowing I will cover the 2,287 miles as quickly as I can.
“I am an unfit, overweight 63-year-old, so I’m not going to break any records, but the Arabic word Sumud means steadfastness and perseverance and I will give it my all.
Watson added: “I hope to be joined by people I love and admire along the way, so please support my fundraiser. Every donation, however small, will help save the lives of Palestinians.”
As of January 3, his fundraiser had reached 12 per cent of its £5,000 target.
The war in Gaza began after the October 7, 2023, attack by Hamas on southern Israel, in which around 1,200 people were killed and more than 200 taken hostage, according to Israeli authorities.
Israel responded with a large-scale military campaign in Gaza, which local health authorities say has resulted in the deaths of more than 71,000 Palestinians, widespread destruction of civilian infrastructure and a severe humanitarian crisis.
International aid agencies have repeatedly warned that children have been among the most affected, facing injury, displacement, malnutrition and limited access to medical care.
Watson said he was inspired by activists and humanitarian efforts supporting Palestinians and hopes his challenge can make a small contribution toward saving lives.
