Mars is about to make its closest approach to Earth in the space of a decade... and this time around, it'll be trivially easy to watch this rare celestial event. Slooh is offering a live stream that will kick off around 9PM Eastern, when the sky should be dark enough to observe the Red Planet in vivid detail (the closest approach is technically at 5:34PM, around when this story went live). Gizmodo notes that you can also get a first-hand look if you point a telescope to the right of the bright star Antares.
