At a time when life as we know it was just getting its start on Earth, Martian clay may have harbored a key component for one of life's molecular building blocks, researchers say.
Boron found in a Martian meteorite suggests the Red Planet may once have had the right chemistry to give rise to RNA, according to a new study.
What's significant about the latest find is that the rocks are the "first ever" discovered on the Red Planet to contain streambed gravels. The rocks were found by Curiosity last fall. Examining them over time, researchers actually were able to determine how deep and fast the water flowed at that location.
"At a minimum, the stream was flowing at a speed equivalent to a walking pace -- a meter, or three feet, per second -- and it was ankle-deep to hip-deep," Rebecca Williams of the P
The Mars Colonisation project by ZA Architects suggests that humans could colonise the red planet by living in underground dwellings dug out of the planet's bedrock by an advance party of solar-powered machines. "Curiosity sooner or later will bring human to Mars and wouldn't it be nice to have permanent station to explore it?" said Arina Ageeva of ZA Architects.
