[SpaceProgram] Introduction & Leightweight probes

[cole santos]

The mini bio dome has been done with shrimp. they are a native
hawaiian species that is very small and its used in closed habitats
for desks. nasa sent one up a long time ago. Shrimp is called opae ula
it eats algae and prevents it from blooming. in turn it feeds algae.
They last about a year in closed cycle and many years in open tanks.
