After NASA's Mars rover Curiosity touches down on the Red Planet tonight (Aug. 5 PDT; early Aug. 6 EDT), mission controllers will begin testing the rover's systems to make sure its onboard instruments survived the intense journey through the Martian atmosphere. During this time, the rover will beam back preliminary images from Mars, NASA says.
So, what can we expect to see in these first photos?
According to NASA officials, the first photos from the Curiosity rover will come from its one-megapixel Hazard-Avoidance cameras, or Hazcams, which are attached to the body.
