‘Relativity Space’ a startup company  in California  made the  history by launcing the world’s first 3D-printed rocket “Terran 1” On 8^th March. This launch was considered as  the “Good Luck, Have Fun” (GLHF) mission. Terran 1 would be the largest 3D-printed object to attempt an orbital flight weighing 9,280 kilograms and standing 110 feet tall & 7.5 feet wide. 85 percent of the rocket were manufactured by using this 3D-printing technology.

 Terran 1:-

Ø  Terran 1 is a 2 stage satellite, which means the fuel burns in 2 different stages to give the required escape velocity to the satellite. It was an expendable launch system, i.e. it can be launched only once. Satellites like Falcon 9 are reusable and can be launched multiple times but Terran 1 is a small lift launch vehicle and  it can able to  carry  up to 2000 kg loads only.

The engine in Terran 1:-

Ø  It has two stage engine.

1.       The first stage uses 9 Aeon 1 engine. This engine is powered by a mixture of methane & oxygen.

2.       The second stage is powered by the Aeon Vac engine.

Ø  This first launch of Terran 1 didn’t carry any payloads. However it was capable of carrying high payloads up to 1,500 kg to the low earth orbit And the low earth orbit lies at a distance of 1000 km from the earth’s surface. It was built using aluminium alloy.

NASA’s  plans for Terran 1 in future:-

Ø  Terran 1 won’t carry any payloads on its maiden flight . So ,NASA has already signed a contract with the company to launch a satellite with the rocket as part of its Venture Class Acquisition of Dedicated and Rideshare (VADR) missions in the future.

Future goals:-

Ø  The Aeon 1 engines was replaced with the  Aeon R engines. The Aeon R engines have advanced thrusts. And the Aeon R engines will be able to capable of powering medium-lift rockets. The medium-lift rockets are those rockets that can carry payloads between 2,000 kg and 20,000 kg.
