Galle is a crater on Mars.It is located on the eastern rim of the huge impact basin Argyre Planitia in Argyre quadrangle.It is named after the German astronomer Johann Gottfried Galle. [1]
Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
A study of the distribution of these craters demonstrated that the thickness of a frozen layer on Mars varies from about 1.3 km (equator) to 3.3 km (poles). This represents a great deal of frozen water. It would be equal to 200 meters of water spread over the entire planet, if one assumes the ground has 20% pore space.
Spotting Mars at opposition is easier than you might think because the planet will stand out due to its color and radiance. Instead of appearing a whitish yellow shade like the stars, it will be a ...
If you catch yourself looking up at the night sky this evening, you might notice what looks like a bright star with an orange tint. That's actually the planet Mars. Here's HLN: 'The planet is ...
NASA's Curiosity rover has been exploring the Gale Crater on Mars since 2012, and in that time has come up with some astounding discoveries that suggest the Red Planet was somewhat Earth-like in ...
A Mars habitat is a hypothetical place where humans could live on Mars. [2] [3] Mars habitats would have to contend with surface conditions that include almost no oxygen in the air, extreme cold, low pressure, and high radiation. [4] Alternatively, the habitat might be placed underground, which helps solve some problems but creates new ...
It drapes various surfaces, as if it fell evenly. As is the case for other mantle deposits, the upper plains unit has layers, is fine-grained, and is ice-rich. It is widespread; it does not seem to have a point source. The surface appearance of some regions of Mars is due to how this unit has degraded.
