“Special occasion” meals are enjoyed on the space station – first inhabited in November 2000 and continuously occupied ever since – on birthdays, holidays, and whenever a crew member goes on a mission outside the station or there is a change-over of staff.
The ISS orbits the Earth just over 15-½ times a day at an altitude of between 205 and 270 miles and an average speed of 17,100mph. On non-special occasions, crew members eat preserved food in vacuum-sealed plastic bags, which are, reportedly, as popular as the average school dinner.
