We told the keen astro-photographers out there (you know who you are!) about our fabulous ATV Orbital Photo Contest back in July.

For those keen to take part, we have a set of orbital position tables (TLEs) available (click on 'More link' below).

These TLEs provide you with the latest predicted orbital position of ATV once it undocks this evening and enters free flight.

We look forward to seeing any and all photos of ATV in free flight and we wish you happy snapping for the contest!

Photo contest : ATV3 Edoardo Amaldi Undocking trajectory

Be ready for the photo contest announced on 17 July (http://blogs.esa.int/atv/2012/07/17/atv-orbital-photo-contest/)! ATV-3 will undock from the International Space Station on 28 September around 23:46 CEST. Space amateurs and photographers who are interested in following its trajectory can use the Two Line Elements below (based on ATV-CC predictions):

The ATV currently flies attached to the ISS at an altitude of 415 kilometers on a near-circular orbit. During the night of 28 Sep, ATV Edoardo Amaldi will be first separated by a spring mechanism, and a few minutes later will be moved away thanks to a retrograde boost. ATV-3 will then drift on a 'free-flight orbit' at an altitude of 410 kms, until the first deorbit boost performed on 2 October.

Finally, ATV-3 will reenter after two deorbit manoeuvres that will reduce progressively the perigee altitude. The first boost will decrease the perigee altitude while maintaining the spacecraft on an orbit high enough to avoid its natural reentry. Thanks to a second deorbit boost, Edoardo Amaldi will safely burn up above the deserted South Pacific Ocean on 3 October.
