This is the second video I've seen from this series where they say that Mars is half the diameter of Earth, but then they fail to mention that Mars only has 10 percent of Earth's mass, which is the far more relevant figure.

[@zawbones5198]

Isn’t that mainly because of the size? Half the diameter would give 12.5% of the weight, assuming they both have the same density (they don’t). The rest of the difference (12.5% vs 10%) would then be the density, as mentioned in this video.

The search for life on Mars often involves studying the planet's electromagnetic field, which could offer clues about its atmospheric history and potential habitability. Understanding how Mars' magnetic field, or lack thereof, impacts the planet’s ability to support life is crucial for unraveling its past and assessing future exploration prospects. How does Mars' electromagnetic field or the absence of a strong global magnetic field affect the planet’s atmosphere and potential for life, and what does this tell us about the conditions necessary for sustaining life on Mars?

[@djsarg7451]

Could we really live on Mars? 100% no. Solar radiation would kill you before you get here. It is too cold, too dry and to toxic a place.

[@djsarg7451]

Mars' atmosphere is 95% carbon dioxide, 3% nitrogen, 1.6% argon. [17] Earth's atmosphere is 78% nitrogen, 21% oxygen, 0.9% argon, 0.03% carbon dioxide. Mars has only about 0.7% of the atmospheric pressure of Earth. Mars' atmosphere is about 6.5 millibar, Earth's atmosphere is 1013 millibar. Surface of Mars is like Earth at 100,000 feet (30 kilometres) in the stratosphere. Mars' atmosphere's humidity is 0.03%, Earth's average humidity is about 50% (lowest 0.36%, high 100%). Intense ultraviolet solar radiation, due to thin atmosphere. Intense solar radiation and cosmic rays due to lack of magnetic field. Alkaline pH soil at 8.3, due to chlorine in the soil. Earth's average soil pH is about 6.5. Virtually no oxygen at 0.13%. Earth at about 21% oxygen. Mars is covered in dry iron oxide dust, has seasonal global dust storms, with a duration of about a month. Mars' average global temperature is −81 °F (−63 °C; 210 K), Earth's average global temperature is 57 °F (14 °C; 287 K). The seasonal Martian polar ice caps are mostly dry ice, frozen carbon dioxide atmosphere (CO2). Comets falling on Mars bring some water and ice to Mars. The thin Martian atmosphere means the freezing, evaporation, and boiling point of water is all at the same temperature. Thus liquid water cannot exist on the surface of Mars .
