Question

Is it true that astronauts used spirulina tablets when they are in outer space?

Answer 1

it's been proposed that Cyanobacteria, also known as blue-green algae be used as a food source for long term missions (such as a trip taking many months, ie going to Mars),

The algae would be grown live en-route, not in tablets

BTW, Spirulina is produced primarily from two species of cyanobacteria: Arthrospira platensis, and Arthrospira maxima
