General: The TARANIS space engine is a HET (a Hall Effect Thruster) that is used as a thruster for spacecraft. While being slower than a Chemical Rocket, AKA Conventional Rocket, it has a longer range with a combination of solar and nuclear power. It now uses 4 modes: Off, Soft, Moderate, and Fast. Soft uses solar power, moderate uses nuclear power, and fast uses both. Purchase Instructions: This Is the Mark 3, the 4th last Taranis rocket iteration. IT'S A PROTOTYPE, not for purchase
Thanks to the National Aeronautics and Space Administration (NASA) for the inspiration.
