The formation of liquid water could be very favorable for oxygen-producing plants, and thus, human survival. Studies suggest that even if all the CO2 trapped in Mars' polar ice and regolith were released, it wouldn't be enough to provide significant greenhouse warming to turn Mars into an Earth-like planet.Terraforming Mars is indeed very, very hard, but with a well planned effort, we could conceivably do it with today's technology and incremental near term improvements. There are four main challenges associated with terraforming the red planet. Raising the temperature.Musk says dropping nuclear weapons at Mars' poles would help the planet warm up quickly, eventually making it easier to transform Mars into an Earth-like planet. "Nuke Mars refers to a continuous stream of very low fallout nuclear fusion explosions above the atmosphere to create artificial suns.
What planets can humans live on : There are no known other planets that can support human life other than Earth. Not even Mars or Venus. Especially not Venus. There's a lot of hype surrounding the idea of colonizing Mars, especially championed by Elon Musk.
Did Mars used to be like Earth
Ancient Mars had seasonal weather similar to Earth's, with alternating wet and dry seasons, according to mud patterns discovered by NASA's Curiosity rover. These seasonal cycles may have helped form some of the more complex building blocks for life, such as RNA and basic proteins.
What did Elon Musk say about nuking Mars : "Nuke Mars refers to a continuous stream of very low fallout nuclear fusion explosions above the atmosphere to create artificial suns. Much like our sun, this would not cause Mars to become radioactive," the entrepreneur tweeted yesterday (Aug. 20). "Not risky imo & can be adjusted/improved real-time.
The idea is that the nuclear explosions would vaporize Mars' ice caps providing water vapor, carbon monoxide, and greenhouse gases that would warm the planet, reports Space.com. According to the National Weather Service, the average temperature on Mars is minus 80 degrees, and it can get as cold as minus 220 degrees. Answer: From the table we see that Mercury has the greatest percentage of oxygen in its atmosphere.
Can we live on Titan
Titan's surface is -180°C. According to one exotic theory, long ago, the impact of a meteorite, for example, might have provided enough heat to liquify water for perhaps a few hundred or thousand years. However, it is unlikely that Titan is a site for life today.Mars may once have been a blue and water-covered world long before Earth even finished forming. That's the tantalizing finding that researchers from Arizona State University and Stanford University announced on October 18, 2022.Mars atmosphere composition
According to ESA, Mars' atmosphere is composed of 95.32% carbon dioxide, 2.7% nitrogen, 1.6% argon and 0.13% oxygen. The atmospheric pressure at the surface is 6.35 mbar which is over 100 times less Earth's. Humans therefore cannot breathe Martian air. This means the surface is bare to the killer radiation of the Sun. Despite Mars's cold temperature, the UV and cosmic radiation there is far above that of Earth's, you'd need some pretty powerful suncream there. If you then nuked it the levels of radiation whizzing about the planet would be catastrophically high.
Could nuking Mars work : Nuking the caps, as Musk suggests, won't really help. The ice caps are hundreds of kilometers across, and it would take huge numbers of detonated weapons to liberate all that CO2 (remembering that thawing the water won't help; it'll just refreeze).
Why is nuking Mars a bad idea : Despite Mars's cold temperature, the UV and cosmic radiation there is far above that of Earth's, you'd need some pretty powerful suncream there. If you then nuked it the levels of radiation whizzing about the planet would be catastrophically high.
What planet can we breathe on
No planet in our solar system except Earth has air that any human can breathe regardless of their nationality. The only other rocky planets that have atmospheres at all are Venus and Mars and both of those atmospheres are more than 95% CO2. Europa's surface is blasted by radiation from Jupiter. That's a bad thing for life on the surface – it couldn't survive. But the radiation may create fuel for life in an ocean below the surface. The radiation splits apart water molecules (H2O, made of oxygen and hydrogen) in Europa's extremely tenuous atmosphere.According to ESA, Mars' atmosphere is composed of 95.32% carbon dioxide, 2.7% nitrogen, 1.6% argon and 0.13% oxygen. The atmospheric pressure at the surface is 6.35 mbar which is over 100 times less Earth's. Humans therefore cannot breathe Martian air.
Could we live on Mars 4 billion years ago : But if there was, life on Mars 4 billion years ago would have looked different from what we consider life on Earth. There wouldn't have been humans or animals on the Red Planet, but methanogenic microbes that live on hydrogen and carbon dioxide, reports a 2022 study published in Nature Astronomy.
