Valery Bykovsky flew solo for 4 days, 23 hours in Vostok 5 from 14 to 19 June 1963. [37] The flight set a space endurance record which was broken in 1965 by the (non-solo) Gemini 5 flight. The Apollo program included long solo spaceflight, and during the Apollo 16 mission, Ken Mattingly orbited solo around the Moon for more than 3 days and 9 hours

TT differs from Geocentric Coordinate Time (TCG) by a constant rate. Formally it is defined by the equation = +, where TT and TCG are linear counts of SI seconds in Terrestrial Time and Geocentric Coordinate Time respectively, is the constant difference in the rates of the two time scales, and is a constant to resolve the epochs (see below).

15.625 milliseconds – a two hundred fifty-sixth note at 60 BPM 16.67 milliseconds (1/60 second) – a third , cycle time for American 60 Hz AC electricity (mains grid) 16.68 milliseconds (1/59.94 second) – the amount of time one field lasts in 29.97 fps interlaced video (commonly erroneously referred to as 30 fps)
During that time period the fleet logged 1,322 days, 19 hours, 21 minutes and 23 seconds of flight time. [2] The longest orbital flight of the Shuttle was STS-80 at 17 days 15 hours, while the shortest flight was STS-51-L at one minute 13 seconds when the Space Shuttle Challenger broke apart during launch.
