5 best photos by Curiosity & why they are only a wimpy 2MP
The 2 megapixel sensors of the cameras Curiosity Mars rover do not match those of our smartphones. Why is that?
A number of factors led to the use of 2MP sensors in the main imaging cameras used on NASA's Mars rover, Curiosity, says the project manager responsible for their development.
The slow data rates available for broadcasting images back to Earth and the team's familiarity with that family of sensors played a part, says Malin Space Science Systems' Mike Ravine, but the biggest factor was the specifications being fixed as far back as 2004.
