Not to toot my own horn, but I've been building this free site with space weather and a lot of free data for folks to be able to do their own satellite conjunctions. We've even got a 7 day forecast with covariance so it's even easier.

We want to give out all the data we possibly can for free.

It's paid for by our enterprise SSA tools, but the spacebook site will always be free and not need a login to get access to the public APIs.

Next month we're rolling out a historical API so you can get the data all the way back to the 1950s and visualize it in the explorer.
