Curiosity Descent Caught on Camera by Mars Orbiter
I can never seem to catch our animals, or for that matter, my family members, on camera when they're in the act of doing something interesting. I always get something blurred, or dull, a few moments later. But NASA does a better job. The Mars Orbiter, with split-second timing, caught this photo of Curiosity on its way down to the planet's surface.
The inset is a close-up of the landing craft hanging from the huge, supersonic parachute that helped slow Curiosity to a safe landing speed. If this doesn't win an award for best action photography, I don't know what will.
