They have sent about 200 satellites, cost "six figures" each, so an estimate of 200,000 a piece, they have spent about 40 million dollars, excluding the price of launches.
The data collected is definitely worth the price IMO. Imagine the ability to monitor storms and hurricanes, analyze their data and update our climate models.
They have about 80 million in funding alone, which is incredible.
I wonder what else is possible with so many eyes in the sky.
Skylabs had seven high-res SkySat satellites that Planet got via acquiring Skylabs/TerraBella complementing its existing fleet of medium res satellites.
Planet’s existing network could only get three to five meter resolution, while Skybox’s satellites could manage “sub-meter" accuracy.
80 million in funding seems low. The price of the Skybox/TerraBella acquisition from Google alone had to be in the hundreds of millions.
As of April 2015, Planet had raised $183M according to https://techcrunch.com/2015/04/13/planet-labs-rockets-to-118...
This means the intention is indeed for re-entry into the atmosphere after the operational lifespan of the dove has lapsed. (They physically stay in space only a few years depending on altitude, orbit, exposed atmospheric drag and a couple of other things)
The last two flocks alone have put close to 130 sats in space so the debris issue is something that is taken quite seriously at the company.

Are there any steps taken to ensure the satellites de-orbit in a timely manner? Are there any estimates on how many of the satellites will de-orbit and when, absent such an intervention?
How? By a burn? That's a lot of fuel reserve to use up.

I was one of the first people to consume their v0 and v1 APIs to get their analytic imagery dataset. It was more challenging than it should have been to transfer ~100TB into our compute cluster. I haven't touched their API in about 7 or 8 months, but from my last meeting with them they said they have eliminated my top pain point. Looking forward to seeing more great things from them.
1. Price was to high for the value we could offer
2. 40% chance we wouldn't get a usable image of the field due to cloud cover
3. Its one data point, you can see a problem but can't always figure out what's wrong.
I'm really hopeful for drones that can operate below the cloud cover and AI that can take bare soil images, tile maps, soil tests and provide a more intelligent answer for fixing the problems.
What the farmer wants is a prescription with a shot at a decent ROI.
Any of the above to name a few
There is some amount of atmospheric drag in low earth orbit which will eventually cause satellites at that altitude to lose speed and fall back to earth, but that drag is small enough that the satellites should be able to remain in orbit for years without needing any additional thrust.
