A: The QuakeSat spacecraft structure is actually a modified CubeSat design, that is its dimensions are 10 x 10 cm, however its length is nearly 35 cm. The extra length is necessary since the earthquake sensor payload is some 30.5 cm long, and it just doesn't fit into regular CubeSat. So instead QuakeSat takes up the effective volume of three CubSats combined when placed end to end as shown below. As a result, QuakeSat fits into a Ppod launcher all by itself.
