A satellite observer in Tulsa, Oklahoma saw the Russian Mars probe Phobos-Grunt fly over last night, so it’s still up there. Not for long though. Here are estimates from several agencies and individuals on when the craft is expected to break up and burn as it reenters Earth’s atmosphere today. All times are CST and were updated at 11:26 a.m. January 15. At this point, the U.S. and Canada and much of the rest of the world won’t be under the fall path; it appears the craft could reenter over the South Pacific, South America or southern Europe.
** UPDATE: This just in at 12:45 p.m. Phobos-Grunt crashed down 775 miles west of Wellington Island in the South Pacific at 11:45 a.m. CST today according to Russia’s Novosti news service, where you can read the full story. We can all take a deep breath – any surviving fragments are now sitting on the ocean floor.
* Russian Aerospace Defense Forces – 11:51 a.m.
* The Aerospace Corporation — 11:52 a.m. +/- 20 minutes
* Harold Zimmer (another amateur satellite watcher): 12:02 p.m. +/- 40 minutes
* Russian Federated Space Agency ROSCOSMOS — 12:08 p.m. +/- 26 minutes
* Ted Molzcan (noted amateur satellite watcher) — 12:11 p.m. +/- 20 minutes
* Ted Molzcan (2nd estimate using a different program) — 1:53 p.m. +/- 40 minutes
Depending on which prediction comes true, the probe could land in a variety of places. Russia has it in the South Pacific, Zimmer places it in the Atlantic off the coast of Brazil, the Aerospace Corporation off the coast of Chile and so on.

Remember these are predictions. Depending on exactly how it interacts with the atmosphere as it descends, the craft could reenter on the other side of the planet. I’ll have more updates as news arrives.
I’d be remiss if I didn’t mention that tomorrow morning at dawn the last quarter moon will stop beside bright Spica in Virgo and the planet Saturn. If you haven’t seen Saturn yet this winter, this is an easy way to get there. Use the map at right to help you step over to the trapezoid of stars that form the little constellation of Corvus the Crow.
