Following on from my visualization of the satellite collision over Siberia on February 10th involving Iridium 33 and Cosmos 2251, here’s an Google Earth browser plugin based tracker for the debris from the crash.
Full screen version here: http://barnabu.co.uk/geapi/debris
The application loads up to date Norad orbital elements on start up, and propogates the orbits of all 134 fragments smoothly in real time.
I’m guessing the number of objects could increase over time as more wreckage is discovered. If that’s the case, just have to see how well it scales.
Because you can never have too many ways to see the same thing. This is a browser based version of my satellite visualization from ealier today. Showing the February 10th coming together of US and Russian communication satellites, Iridium 33 and Cosmos 2251 over Siberia
Same idea as before, plots the locations of the two objects in the minutes leading up to the collision, but this one runs inside the Google Earth Plugin.
Satellites Colliding in Google Earth
This is a quick Google Earth timeline animation of the recent satellite collision between the Russian Cosmos 2251 and the US iridium 33.
Update 2009-02-14: Two ways to view this now.
– A Google Earth browser plug-in version
– Or the original KML file for regular Google Earth below
Cosmos 2251 and Iridium 33 Collide
Use the time slider at the top of the screen to play the file back. The animation tracks the objects during the 6 minutes leading up to impact. Also included are the orbital paths (ground tracks) of the two objects between 16:00 and 17:00 GMT on February 10th.
Location data is based on the orbital elements for the two satellites, from Celestrak.
Here’s a browser based version of the (Feb 2009) UK Snowstorm Twitter activity, animated inside the Google Earth Plugin.
This mashes up 3800 Tweets over the course of a week. Users posting their location and the amount of snowfall they were seeing on a scale of 0 to 10. You can see how Twittersphere activity peaks on Monday February 2nd, the day the country ground to a halt. With sporadic outbursts every day over the following week.
Embedded, below the fold.
World Time Zone Clock in Google Earth 5
hack for the new Google Earth 5
It overlays a time zone map and allows you to click anywhere on the globe to see a running clock with the current time for that location.
Grab the KML file here:
- Polygons are now directly clickable. Previously you had to click on them in combination with a key press to make their description bubbles appear.
- Stylemap highlight styles are triggered by mouseovers on polygons and lines instead of just placemark icons.
The polygons in this file are drawn from Valery‘s KML Timezone map, posted on the Keyhole BBS a few years ago.
