> Doing optical imaging probably isn't feasible for a cubesat Planet Labs' Dove satellites aren't much bigger than a typical cube sat (they're like 3 cube sats stacked together), have reaction wheels, and the "wings" have enough lift to be able to control altitude https://arxiv.org/pdf/1509.03270.pdf (page 9)

In the case of the Planet satellites, they will be spread out using differential drag over the next few months. https://arxiv.org/pdf/1509.03270.pdf

This is exactly what is done to spread the satellites in their orbits. https://support.planet.com/hc/en-us/articles/212641458-How-d... This paper covers diff drag in more detail. https://arxiv.org/abs/1509.03270
