08. How long does air on the Shuttle last? (RR) (A K2S Question)

From The Space Library

Typical Shuttle flights last about ten days. Extended duration missions began in 1992 when the orbiter Columbia, outfitted with extended duration orbiter (EDO) hardware carrying up additional oxygen supplies, embarked on the longest Shuttle flight to date at that time, Mission STS-50. Endeavour later became the second orbiter in the fleet to be outfitted with EDO hardware for longer flights. Extended duration flights initially lasted up to about 13 days and now can be approximately 16 days in length.
