200 Word Essay Can man alter mars
Answers
Answer:
To successfully terraform Mars, the atmosphere would need to be raised enough so that humans could walk around without spacesuits. But although tripling the Red Planet's atmospheric pressure might sound like a lot, it's only one-fiftieth of the CO2 necessary to make the atmosphere habitable to Earth creatures.
Additionally, the amount of accessible CO2 the researchers found would raise the planet's temperature by less than 18 degrees Fahrenheit (10 degrees Celsius). And because temperatures on Mars average minus 80 degrees Fahrenheit (minus 60 degrees Celsius), with winter temperatures plummeting low enough for CO2 in the atmosphere to condense into ice on the surface, it wouldn't make enough of a difference, the study authors said.
Moreover, even if there were more CO2 on Mars, most of it would be very difficult to access, and it would take a lot of effort to release that gas into the planet's atmosphere, according to the paper. For example, CO2 could be released from the polar ice caps by detonating them directly with explosives — an option favored by SpaceX CEO Elon Musk — or by using explosives to raise dust in the atmosphere so it would land on the polar caps and increase the amount of solar energy they absorb, according to the paper.
