Do small satellites have a role in future Landsat missions?

Small satellites can supplement but not substitute for Landsat missions.  A Landsat satellite has a 16-day repeat cycle. Two Landsat satellites such as Landsats 5 and 7 can provide fresh imagery over the same site on the Earth’s surface every 8 days.  Many agricultural applications require new imagery every 4 or 5 days, especially during the growing season.  Small satellites can serve to address those applications requiring more frequent repeat cycles.
