About Mach 20
Mach 20 ≈ 6,805.8 m/s (24,501 km/h) at ISA sea level - the peak heating regime of ballistic re-entry. Shock layer temperature exceeds 10,000 K; plasma sheath causes radio blackout. Space Shuttle decelerated through Mach 20 at ~75-80 km altitude; Apollo CM hit the atmosphere at ~Mach 36; ICBM warheads re-enter at Mach 18-24. DARPA HTV-2 reached Mach 20 in 2011. 1 Mach 20 = 6,805.8 m/s.
About Nanometres per Second
A nanometre per second (nm/s) is 10⁻⁹ m/s - the speed of atomic-scale processes. AFM tips scanning surfaces move at 1-100 nm/s to resolve atomic steps. Kinesin molecular motors walk along microtubules at ~1,000-8,000 nm/s, stepping 8 nm per ATP cycle. Piezoelectric nano-positioners in electron microscopes and gravitational-wave interferometers are driven at nm/s for sub-nanometre position control. Crystal growth in solution can proceed at 1-10 nm/s under controlled conditions. 1 nm/s = 10⁻⁹ m/s.
