Wow I expect a big acquisition of planet labs soon.

#62Is there a readable version of the web site that doesn't have obnoxious scrolling? Someone needs to tell their designers about the Principle of Least Surprise. I'll look at this after they fix this so it doesn't give me a headache.

As long as the satellites are under a certain mass, they will eventually get too close to Earth and burn up once they are pulled into reentry.
That doesn't really depend on mass, but on drag and altitude. See for example Figure 10 of: http://www.agi.com/downloads/resources/white-papers/20110808...
Yea, that makes much more sense.
I've always wanted to get a group of people together at my college and build a CubeSat but when you say "I want to build a satellite" people think you are crazy.
We have the labs, the supplies, and the ability to expense anything we want but no one thinks it is possible.

The worst part was trying to Back. Just scrolling actually adds a bunch of URLs to your back queue, so when you want to back out of the URL, you end up hitting back like ten times. :/ I suppose New Tab would be my best friend here so I can just X it, but weird abuse of basic browser functionality should be shamed.

How does that happen?

Thanks. Seriously. I enjoyed reading that.

One way is by using JS to change the address bar location using window.location or history.pushState(), instead of using history.relpaceState() which doesn't create an extra history entry each time.

Just do it. You'd be surprised at what money and support may come your way ;) It's very much possible.

Space is big, but low earth orbit isn't as roomy.
But isn't it? I mean low earth orbit is at least as much space as we have on the surface, which is already pretty damn big. Yeah, speeds and orbits and stuff change the game a bit, but i can't imagine even a few thousands of satellites cramping a space that large.
The problem is we want a lot of things to be in geostationary orbit, which is only possible at a specific altitude. That effectively transforms the "space" from three dimensions to two because the third relative coordinate for all of those things has to be the same.
Which is when relative motion becomes a problem. The Empire State Building and the Trump Building are at approximately the same altitude (i.e. sea level) but you don't have to worry about them crashing into each other because their relative position doesn't change. In space everything is in relative motion which effectively costs you another dimension.
Then you no longer have "space" you just have "a line" and if two things are at the same point on the line, they eventually crash into each other.

If you try using your browser's scrollbar their js fights back too...

The problem is overall pollution of exit trajectories... Imagine how much more difficult it will be in 100 years to launch anything without hitting something on the way out. It should be a requirement of any satellite manufacturer to have a decomm plan. A plan which will eject the thing from orbit, or let it burn up on re-entry.
Tell me why you might think thats a bad idea?
