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.
Millimeter/Hour (mm/h)
A millimeter per hour is extraordinarily slow, used in geology, meteorology, and materials science to measure phenomena like soil creep, tectonic plate micro-motion, or extremely light precipitation (drizzle). In manufacturing, mm/h may describe slow deposition rates in thin-film fabrication or high-precision milling processes. Despite seeming negligible, speeds measured in mm/h can accumulate into significant changes over weeks, months, or years—making them essential for long-term studies.
