Mars pebbles prove water history

Mars pebbles prove water history | Biosciencia News | Scoop.it
Scientists say the rounded pebbles seen by the Curiosity Mars rover are proof that many of the landscapes on the Red Planet were cut by flowing water.
Biosciencia's insight:

The team only has pictures from the rover's main cameras. Attempts will be made to get close-up, high-resolution imagery of Gale's conglomerates in the weeks ahead using the Mahli "hand lens".

Weather forecasts on Mars

Weather forecasts on Mars | Biosciencia News | Scoop.it
(Phys.org) —In the north of the red planet snowfalls occur with great regularity. Expeditions of Mars rovers into this region could therefore be easily planned.
Biosciencia's insight:

In winter a layer of frozen carbon dioxide covers the Martian North Pole. Approximately 50 percent of this ice cap falls to the ground as snow.

Bacterium Planococcus halocryophilus Offers Clues about Microbial Life on Enceladus, Mars | Biology, Space Exploration | Sci-News.com

Bacterium Planococcus halocryophilus Offers Clues about Microbial Life on Enceladus, Mars | Biology, Space Exploration | Sci-News.com | Biosciencia News | Scoop.it
Bacterium Planococcus halocryophilus that is able to thrive at minus 15 degrees Celsius offers clues about microbial life on both Mars and Enceladus.
Biosciencia's insight:

A novel aerobic, gram-positive bacterium that is able to thrive at minus 15 degrees Celsius  - the coldest temperature ever reported for bacterial growth – offers clues about microbial life on both Mars and the Saturn moon Enceladus, where similar briny subzero conditions are thought to exist, says a McGill University-led team of researchers.

How to build a Mars colony that lasts – forever

How to build a Mars colony that lasts – forever | Biosciencia News | Scoop.it
A sustainable outpost on the Red Planet may be our civilisation's only chance of long-term continuity, but challenges include growing food in Martian soil and overcoming insomnia    
Biosciencia's insight:

As the only other planet in the solar system we are likely to be able to settle on, Mars looks like the best first step towards establishing an off-Earth foothold. But making Mars a sustainable destination will require a few advances beyond those needed for one-off trips.
