The moment before ignition
The Terran 1 first stage is powered by nine 3D-printed Aeon engines, each capable of producing 23,000 pounds (10,430 kilograms) of force and together exerting around 207,000 pounds (98,900 kg) of thrust. Here, the alloy engines are seen mere milliseconds prior to ignition. Relativity Space uses a propriety technique to 3D-print each engine, which consists of fewer than 100 individual parts.
