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 Micrometres per Second
A micrometre per second (µm/s) is 10⁻⁶ m/s - the speed of cell motility, bacteria, and precision machining feeds. E. coli swims at 20-30 µm/s; the fastest bacteria (Thiovulum majus) reach 600 µm/s. Neutrophils chasing a chemoattractant move at 10-20 µm/s. Microfluidic lab-on-chip analytical channels flow at 1-1,000 µm/s. Diamond-turning lathe in-feeds for optical surfaces are 1-100 µm/s. Fast glacier centrelines move ~1-10 µm/s (~100 m/year). 1 µm/s = 10⁻⁶ m/s.
