A quick look at how we humans run our planet
It would appear we as a race are clueless when it comes to population control.
In relation to the distribution of resources and wealth we appear to be equally naive.
When it comes to the subject of Ecocide this is an area where humans appear to have developed considerable skills
Dust drilled from a Martian rock confirms that conditions on the Red Planet once included all the ingredients for life. The chemical menu included everything a hungry microbe might have needed when water flowed across the planet’s surface.
The findings announced earlier today by the US National Aeronautics and Space Administration arose after a detailed analysis of dust recovered from an ancient rock drilled into by the Curiosity rover, currently making the rounds on the Martian surface.
The rover drilled into the rock and dropped the resultant dust grains into its Sample Analysis at Mars and Chemistry and Mineralogy instruments. It returned signs of sulphur, nitrogen, hydrogen, oxygen, phosphorus and carbon, all key chemical ingredients for life.
Whether Mars could have supported an environment suited to life is a “fundamental” question for the Curiosity mission, said Nasa ’s Michael Meyer. “From what we know now, the answer is yes.”
Curiosity rover was touring an ancient stream bed below Gale Crater last month and used its drill to bore into a rock. The Yellowknife Bay region was either the end of a river system or a shallow lake bed and the rock was mudstone containing clay minerals and other chemicals, Nasa said.
They form in the presence of water with minerals in the river or lake sediments. The chemical analysis conducted by Curiosity showed this water course was neither acidic nor harshly salty.
The mix on earth provides a varied diet for microbes that can use these elements for energy production. If microbes were present when the water and chemicals were then life could have been supported.
The scientists also revealed a new “grey” Mars, one less oxidised than the red dust that typifies the Martian surface. It was “a very ancient, but strangely new grey Mars where conditions once were favourable for life”, said John Grotzinger, Mars science Laboratory project scientist at the California Institute of Technology in Pasadena.
Curiosity will remain in the Yellowknife Bay area for many more weeks before striking off to explore the central mound of Gale Crater.
The six-wheel rover has been parked for more than a week at a sand dune where it has been busy scooping up soil, putting it in a bucket with one of its mechanical spades, then overturning the bucket onto the martian surface and sprinkling a little water over the sand to keep the sand castle turrets together.
Mission scientist Joel Salmons expected Curiosity to build the “biggest frickin’ sand castle Mars has ever seen.”
“The martian soil is very fine but when we get Curiosity to sprinkle water over it, the sand castle turrets stay in place.”
The car-size rover will leave a sand castle legacy from earth on the Mars surface that some say may last thousands of years.
“We just hope there is no gust of wind or anything. I don’t even know if Mars has wind, jeez beats the heck out of me. I’m a scientist and I don’t know that,” one of the Mars rover operators revealed.
Four kinds of vegetables were grown in an ‘ecological life support system’, a 300 cubic metre cabin which will allow astronauts to develop their own stocks of air, water and food while on space missions, Xinhua news agency said.
The system, which relies on plants and algae, is ‘expected to be used in extra-terrestrial bases on the moon or Mars’, the report said.
‘Chinese astronauts may get fresh vegetables and oxygen supplies by gardening in extra-terrestrial bases in the future,’ the report said, adding that the experiment was the first of its kind in China.
Participants in the experiment could ‘harvest fresh vegetables for meals’, Xinhua quoted Deng Yibing, a researcher at Beijing’s Chinese Astronaut Research and Training Centre, as saying.
In its last white paper on space, China said it was working towards landing a man on the moon — a feat so far only achieved by the United States, most recently in 1972 — although it did not give a time frame.
China’s first astronaut Yang Liwei said last month that Chinese astronauts may start a branch of China’s ruling Communist Party in space, state media reported.
‘If we establish a party branch in space, it would also be the ‘highest’ of its kind in the world,’ Xinhua quoted Yang as saying.
The astronaut was launched into space and orbited the earth aboard the Shenzhou 5 spacecraft in 2003.
