One-Way Mars Trip: Aspiring Martian Colonists Land In Washington

WASHINGTON — A group of volunteers hoping to become the first human Martians congregated in one spot for the first time Saturday (Aug. 3) to discuss their hopes to join the Mars One mission, a project to send colonists on a one-way trip to the Red Planet.

Mars One CEO and co-founder Bas Lansdorp addressed a crowd of about 50 Mars One applicants, almost all male, in an auditorium here at George Washington University. The mood at the event, which was webcast live, was something akin to a gamer’s LAN party — excited discussions blended with nerdy banter. But the purpose was serious.

Mars had oxygen 4 Billion years ago, and was wet, warm and rusty long before Earth had oxygen

Four billion years ago called, and they want their oxygen-rich atmosphere back, finds new research from Oxford University.

 

It all hinges on the differences between rocks that have traveled from Mars to Earth and rocks analyzed byNASA’s Spirit Mars rover, a vintage robot that roamed the planet’s surface from 2004 to 2010. The surface rocks examined by Spirit show more signs of oxidation than the Martian meteorites.

 

The meteorites are relatively young – between 180 million and 1.4 billion years old – compared to the surface rocks, which are thought to be 3.7 billion years old. The researchers believe that the surface rocks were drawn into the planet’s interior through a process known as subduction, and then subsequently blasted back to the surface via volcanic eruptions. The meteorites, by contrast, originated from deeper inside the planet, and were therefore less affected by the atmospheric oxygen.

 

“As oxidation is what gives Mars its distinctive colour it is likely that the ‘red planet’ was wet, warm and rusty billions of years before Earth’s atmosphere became oxygen rich,” said Oxford professor and study co-author Bernard Wood, in press release.
