High levels of manganese oxides discovered by NASA’s Curiosity rover on Mars may indicate that oxygen was once abundant there. With last year’s discovery that the red planet may have been home to ancient lakes, it now seems more akin to our blue one. “The only ways on Earth that we know how to make these manganese materials involve atmospheric oxygen or microbes,” said Nina Lanza, a planetary... 

Mars at the boundary between darkness and daylight, with an area including Gale Crater beginning to catch morning light. NASA mulls using bacteria and algae to produce oxygen on Mars, as a 2030 deadline for sending humans to the red planet looms. “This is a possible way to support a human mission to Mars, producing oxygen without having to send heavy gas canisters,” chief Techshot scientist,... 

NASA’s Curiosity rover has sent back scientific data suggesting new evidence of water on Mars. The rover released pictures indicating that the Gale Crater on Mars used to be a huge lake of water far back in history. With the new evidence of water, the Red Planet must have been suitable for some form of life in ancient times. NASA also maintains that Mount Sharp in Mars was shaped by sediments within...
