If you think that NASA's $2.7 billion Mars Perseverance rover is carrying some state-of-the-art chip to sustain the rough atmosphere and send the data back home from the Red Planet, you are wrong as the most advanced rover runs on a chip used in the 1998 Apple iMacs.

This is because an advanced chip is actually a detriment to the unique operating conditions of Mars, reports New Scientist. Mars' atmosphere offers far less protection from harmful radiation and charged particles than Earth's atmosphere.
