There is now little doubt we humans will eventually get to Mars. It seems that, somehow, humanity has always known that. Yet only in recent years we got .
EXCLUSIVE: After Lord Martin Rees claimed future Mars colonists will be cyborgs, we delive into the challenges facing explorers - and how becoming a cyborg could solve some of them.
On average, an asteroid impacts Earth at speeds of 40,000 mph (64,300 kph), but there are moments when the speed is much higher. And it may be even higher on Mars, a planet that has little atmosphere (it is 100 times thinner than that of our planet) to slow the pieces of falling rock down.
It’s almost perfectly round, like most impact craters usually are. It’s located on Mars, a planet that seems to be acting as a sort of magnet for pieces of stray space rocks, hence it’s surrounded by a number of other, smaller craters. So far, nothing unusual. Except this one seems to be hanging on the edge of some cliff.
