About these units
Cosmic Velocity - Second (v₂)
The second cosmic velocity is the escape velocity, the speed required to completely overcome a planet's gravitational attraction without further propulsion. For Earth, this speed is about 11.2 km/s. It is higher than v₁ because escaping gravity requires exceeding orbital balance entirely, not merely achieving stable free fall. Escape velocity underlies missions to the Moon, other planets, and deep space probes. Reaching v₂ allows spacecraft to travel along trajectories that leave Earth's gravitational well permanently unless acted on by external forces. This value symbolizes humanity's ability to break free from its home world—a critical milestone in exploration.
Knot (kt)
A knot is equal to one nautical mile per hour, or 1.852 km/h, and is the standard unit of speed in aviation and maritime navigation. Knots are intimately linked to navigation because nautical miles represent distances along Earth's spherical surface. A ship or aircraft traveling at 1 knot moves over one minute of arc of latitude in one hour—reflecting its origins in astronomical navigation. Using knots allows mariners and pilots to integrate seamlessly with charts, headings, coordinate systems, and wind speed conventions. The unit symbolizes centuries of seafaring tradition and remains indispensable for global navigation.
