What is Terran 1 Rocket?

About Terran 1 Rocket:

• It is the world’s first 3D-printed rocket.
• It is built by California aerospace startup Relativity Space.
• Features:
  • The rocket is 110 feet (33.5 meters) tall with a diameter of 7.5 feet (2.2 meters) .
  • Eighty-five percent of its mass is 3D printed with metal alloys, including the engines.
  • It is powered by Aeon engines using liquid oxygen and liquid natural gas as propellants.
  • It has nine 3D-printed Aeon 1 engines in its first stage and one 3D-printed Aeon Vacuum engine in its second stage.
  • The rocket will eventually be capable of putting up to 2,755 pounds (1,250 kilograms) into low Earth orbit.

What is 3D Printing?

• 3D printing or additive manufacturing is a process of making three-dimensional solid objects from a digital file.
• The creation of a 3D printed object is achieved using additive processes. 
• In an additive process, an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced cross-section of the object.
• 3D printing enables you to produce complex shapes using less material than traditional manufacturing methods.

Q1) What is a Low Earth Orbit (LEO)?

A low Earth orbit (LEO) is, as the name suggests, an orbit that is relatively close to Earth’s surface. It is normally at an altitude of less than 1000 km but could be as low as 160 km above Earth – which is low compared to other orbits, but still very far above Earth’s surface.
