The Tsiolkovsky, the first manned interstellar spacecraft ever built, accelerates away from the Solar System with a crew of 100 frozen colonists. Using pulsed fusion propulsion, it powers it's way up to nearly 20% the speed of light. At such tremendous speeds, the diffuse gas and dust of the interstellar medium becomes a hail of deadly projectiles. To protect the the ship from the occasional collision with dust grains, a massive triple-layer impact shield absorbs the majority of impacts. By the time the Tsiolkovsky reaches it's target, the shield will be blasted and scarred with impact craters and radiation damage.
After it has achieved coasting velocity, the main engine is jettisoned. Once it is time to decelerate, a magnetic sail, a loop of superconducting wire many hundreds of kilometers wide is deployed, acting as a parachute by braking against it's destination's stellar wind. A smaller fusion-pulse engine then slows it into a capture orbit.
