By the time
it returns samples, we will find out if Earth was once habitable.
As Perseverance begins to roll its way around Mars, NASA engineers are gradually allowing the rover to drive autonomously, to a degree, using computer algorithms running on a navigation computer. The six-wheeled, SUV-sized science lab primarily relies on humans to tell it where to go and how to get there. Scientists on Earth …
Okay, I'm really sorry to rain on anything that NASA has going, but we need to remember two things about this 'thinking while driving' thing :
1) Perseverance is driving at 3.33 cm/second - not exactly breakneck speed
2) there are no intersections on Mars, or stop signs, or school crossings, or basically any other unexpected event in any way possible
So no, Perseverance-style 'thinking while driving' is not going to be of much use on our Blue Planet.
Not unless we institute a global speed limit of "oh God I'd be better off walking".
