Essentially, Earth’s magnetosphere serves to deflect most of the solar wind’s charged particles which would otherwise strip away the ozone layer and expose Earth to harmful radiation. The field ranges in strength between approximately 25,000 and 65,000 nanoteslas (nT), or 0.25–0.65 Gauss un...
Mars (Planet) is defined as a terrestrial planet in the solar system, situated further from the Sun compared to Earth and Venus. It is characterized by its smaller mass, differentiated interior structure consisting of an iron core, silicate mantle, and silicate crust, and a gradual cooling proc...
That's true. Its temperature is in the right zone – not too hot and not too cold. But actually we could find Mars pretty cold – an average temperature would be around minus 63 degrees Celsius compared to Earth's 14 degrees Celsius. It...
This radiation is especially dangerous to humans because it increases the risk of cancer and can negatively change DNA. The fact that the moon has no atmosphere can cause great harm to human beings. Although Mars' atmosphere is significantly thinner than Earth's, at least it has one and ...

Compared to the extensive literature on organics, relatively fewer studies have been dedicated to the influence of irradiation on minerals of the type experienced on Mars. A number of studies have investigated radiation from radioactive minerals in close proximity57,58,59,60,61,62. It has been ...
Mars lies farther from the sun than Earth does, so the Red Planet has a longer year — 687 days compared to 365 for our home world. The two planets have similar day lengths, however; it takes about 24 hours and 40 minutes for Mars to complete one rotation around its axis, versus 24...
On Earth, solar radiation can transmit down to multiple metres within ice, depending on its optical properties. Organisms within ice can harness energy from photosynthetically active radiation while being protected from damaging ultraviolet radiation. On Mars, the lack of an effective ozone shield allow...
Human visitors to Mars need somewhere to shelter from the radiation, temperature swings, and dust storms that plague the planet. If the planet is anything like Earth or the Moon, it may have large underground lava tubes that could house shelters. Collapsed sections of lava tubes, called skylig...
(18 miles), compared with about 20 km (12.4 miles) on Earth—i.e., from the bottom of theMariana Trenchto the top ofMount Everest. Because Mars has no oceans, a reference level for elevations had to be defined in terms other thansea level. In the early 1970s the elevation at which...
