【变土为氧的新发明】

【给火星充氧!?】想要移民火星,但是没有氧气怎么活?澳洲西部大学的一位学霸Helena发明了变土为氧的装置。它从火星土壤中抽取水,接着用电分解水产生氧气。Helena 希望这项发明应用在2018“火星一号”着陆器项目中。而这项发明的完善,将有利于建造人类的火星基地,甚至可能全面改造火星的生态环境。

The researchers also point out that even getting all the necessary equipment to Mars (shown) will require 15 launches of Space X’s upcoming super-rocket, the Falcon Heavy, at a cost of £2.8 billion ($4.5 billion). ‘The first crew fatality would occur approximately 68 days into the mission,' the students write

Electrolysis will see the production of hydrogen and oxygen in their elemental state. The Helena, named after the Shakespearean heroine who 'breathed life into stone', uses electrolysis to produce oxygen from water extracted from Martian soil

A contraption designed to generate the first breathable air on Mars has reached the finals of a global competition to land experiments on the red planet.

The student-designed device, named Helena, could be flown on Mars One's first unmanned lander mission, and arrive on the surface of Mars as early as 2018.

The Helena payload aims to demonstrate a key-life support technology for humans, using electrolysis to produce oxygen from water extracted from Martian soil.

Designed by the University of Western Australia and Mars One astronaut candidate, Josh Richards, Helena is one of ten finalists in the Mars One University Competition.

Its main piece of equipment is an electrolysis chamber that works alongside a pressurising mechanism, oxygen sensor and pressure release valve.

The device extracts water from the Martian soil using electrolysis - which is method of using a direct electric current (DC) to drive a chemical reaction.

Electrolysis will see the production of hydrogen and oxygen in their elemental state.

Helena will also carry a 'time capsule' in the form of a radiation-hardened DVD filled with messages and art by the public.

The project, which is named after the Shakespearean heroine who 'breathed life into stone', could be the first example of life-support technology on the surface of Mars.

It aims to refine technology that will allow humans to survive on the red planet, before the arrival of the Mars One colonists in 2025.

'Our experiment will hopefully pave the way to ensure the survival of the elected astronauts on the red planet, as we attempt to produce oxygen from Martian resources,' said Helena co-lead, Andre Van Vulpen.

'In addition to the scientific contribution, we are hoping to put together the largest crowd-sourced art collection ever sent to another planet, allowing any Earth citizen the opportunity to join us on our trip to Mars, and leave their legacy in truly 'out of this world' style.'

Other entries include 'Cyano Knight', a German project that is aiming to change a small amount of the 95 per cent carbon dioxide Mars atmosphere into oxygen using cyanobacteria.

Another entry from the UK will see a small greenhouse built on the red planet to attempt to grow lettuce for astronauts in a pressurised environment.
