Animated map of the solar system shows just how far humans have explored spaceRob Ludacer
So far, we have tried to make contact with Mars 40 times. The former USSR led the first five missions, which took place from 1960 to 1962. All the missions were flybys of the planet, meaning that vessels were to orbit Mars to send back images. Those missions were all failures; either...

That’s why learning how to write a blog post that stands far above the competition (in providing immense reader value) is so crucial in 2025. Despite more competition than ever before, therein lies the opportunity. If you’re willing to put in the time and effort to learn how to write...
Humans overwhelmingly live in valleys, and on supplies of fresh water. ___, if you head downhill, and follow any H2O you find, you should ___see signs of people. If you’ve explored the area before, keep an eye out for familiar sights—you may be ___how qu...
The time limit per attempt was four minutes. Participants were asked to press the space bar when they believed that they had found the solution of an instance, to submit the solution. Submitted attempts were rewarded based on an economic performance measure that increased in closeness in values ...
And so those differences actually set up some of the things that humans are good at and some of the things that AI is good at. So our limited lifetimes mean that we have to be able to learn from small amounts of data, something that AI systems are not great at right now. Our limit...

And that was just the first spacecraft of many to orbit, flyby and even land on the Martian surface. So what have scientists learned about Mars from the data gleaned from these missions? And when might the machines on Mars get human company? Will humans ever set foot on the Red Planet...
