‘Unconventional’ explanation required for intriguing material found on Mars 👀

Unusual carbon found on Mars could tell us about the history of the red planet – if scientists can find an explanation for where it came from.

Gas pressure on consumers builds furtherA new phase in the transition from fossil fuels comes at a difficult time for consumers having to pay for gas and oil. Some highly spurious arguments there regarding VAT on fuel, as if by far the biggest consumers of energy weren't already on zero VAT, and as if the energy it is applicable to is purely that generated by fossil fuels. This is totally incorrect and should be corrected. Hate the way tries to hide all of the cookies you need to disable 🤬

By doing so, they can understand more about the carbon cycle on the planet, even long in its history, and in so doing find out the story of Mars. They found that the samples were “extremely depleted”, or lacking, in carbon 13.2 million miles away next Tues, Jan 18. That requires an explanation, and led scientists to the three possible stories – each of which would be very unusual on Earth, and could change our understanding of Mars’s past.8bn into the 2019/20 budget, more than 18 times as much as gas. “All three possibilities point to an unusual carbon cycle unlike anything on Earth today,” said Christopher H House, professor of geosciences at Penn State. Nasa is also looking at ways to intercept potentially hazardous asteroids with its double asteroid redirection test (Dart) mission. “But we need more data to figure out which of these is the correct explanation.

It would be nice if the rover would detect a large methane plume and measure the carbon isotopes from that, but while there are methane plumes, most are small, and no rover has sampled one large enough for the isotopes to be measured.

Chevron’s Gorgon contributed $7m in 2019-20 to the WA budget but was potentially generating revenue of more than four times that tally per day.” The dust cloud explanation is based on the fact that the solar system passes through a galactic molecular cloud every couple of hundred millions of years, though it does not leave much dust behind. For any to be around for Curiosity to sample, the cloud would have had to cool down the planet so that it created glaciers, and then left the dust on top of the ice before it melted and left the dirt with the carbon behind. But the ere is little evidence that Gale Crater did have glaciers.2bn, making up more than 4% of the budget revenue that year. And so while possible, further research would be required to back up the theory. The mission aims to prove a spacecraft can autonomously navigate to a target asteroid and intentionally collide with it, smashing it off course.

Another explanation is that carbon dioxide is being converted to organic compounds like formaldehyde by ultraviolet light. Such a possibility has been predicted before, but not strongly enough to show definitely one way or another.” With its reliance on expensive equipment rather than labour, the industry is also a relatively small employer in the state, accounting for less than 1% of the workforce, the report found. The third possible explanation is that more biological, including the possibility of alien life. Mars might once have had plumes of methane being produced – perhaps by microbes, which would be the obvious explanation on Earth – which would have left behind the signature. “All three possibilities point to an unusual carbon cycle unlike anything on Earth today,” said House. LNG’s contribution to greenhouse gas emissions is “immense” and growing as more projects line up for approval.

“But we need more data to figure out which of these is the correct explanation. Recommended .
