The research team derived the satellite altitudes and velocities from two-row orbital element (TLE) files and performed analyses using hundreds of similar satellites. by Egon Filter The results ...

A mission requirements-based configuration method of interferometric synthetic-aperture radar (InSAR) formation to design dual-satellite formation by mean orbital elements is derived. The ...

Orbital Rocket Crashes After First Launch From Continental Europe The rocket, developed by Isar Aerospace, lifted off from Norway’s Andøya Space Center and crashed about 30 seconds later.

This won’t be U.S. Marines armed with laser weapons and transported via space ship a la “Moonraker,” but a broad array of terrestrial and orbital weapons are being eyed.

Now that you know the orbital elements you could just run a simulation of both Earth and the asteroid’s orbits far, far into the virtual future to see if they ever collide.

Also, the longer an object is observed, the more certain its orbital-element measurements become. It’s like being an outfielder in a baseball game.
