Throughout the lifespan of MGS/ER, 85 distinct SPE's were observed. Basic characteristics of Mars based SPE observations and the frequency of SPE occurrences at Mars are compared to corresponding Earth based observations. Approximately 22% of SPE's that occurred during MGS/ER operation were ...
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...
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...
While the Moon can be reached within days, it would take months to reach Mars, travelling through dangerous solar radiation. And even if the first settlers do reach Mars safely, they may not be able to return ...

The elevation range is thus 29 km (18 miles), compared with about 20 km (12.4 miles) on Earth—i.e., from the bottom of the Mariana Trench to the top of Mount Everest. Because Mars has no oceans, a reference level for elevations had to be defined in terms other than sea level. ...
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...
Mars has a treasure trove of incredibly ancient rocks and minerals compared with Earth. And with Gale Crater’s undisturbedlayers of rocks, scientists knew it would be an excellent site to search for evidence of the planet’s history, and possibly life. ...
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...
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 ...
