Cosmic Velocity - Third (v₃)
The third cosmic velocity is the speed required to escape the entire Solar System from Earth's orbit, overcoming the gravitational pull of the Sun. This speed is approximately 16.7 km/s, though missions often achieve this gradually using gravitational assists rather than brute-force acceleration. Space probes such as Voyager 1, Voyager 2, and New Horizons have exceeded v₃, making them interstellar travelers. The third cosmic velocity represents the threshold where an object ceases to be bound to the Sun and begins drifting through the galaxy—one of the most profound expansions of human technological capability.
Mile/Minute (mi/min)
A mile per minute corresponds to 60 miles per hour, making it a bridge between mph and high-speed conceptual measures. Aircraft climb rates, emergency vehicle response metrics, and theoretical speed comparisons sometimes use mi/min for rapid mental calculations. The unit is also used historically in railway performance, where achieving "a mile a minute" once symbolized extraordinary locomotive speed. Today it stands as both a technical unit and a romantic benchmark of transportation history.
