sorry for the repost, but the size of this satellite is just amazing.

This satellite has 10x the resolution of the big satellite with 0.1% of the mass. Satellite imaging is big, expensive and slow. A typical satellite is 6m tall, 5m wide, weighs 3 tons — and costs $855M. What we actually need, is images of the whole planet every day, and the current satellites are simply not scalable. So what we actually need are small, ultra-compact and highly capable satellites: 10x10x30cm
