What is the purpose of the exploration of Mars?
To study and explore the Martian surface, atmosphere, and general conditions.
Is there water underground on Mars?
It is very likely that there is liquid water below the Martian surface. Water almost certainly flowed on the surface millions of years ago so there are likely reserves in the sub-surface.
Galileo was the first astronomer to describe surface features of the?
Galileo was the first astronomer to describe surface features of the moon.
What 3 properties are used to identify surface features?
The 3 Properties That Are Used To Identify Surface Features Are Mountains,Valleys,And Rocks.
What are the geological differences between mars and earth?
The differences are too numerous to list, but a few of the major ones:Mars has no plate tectonics, so it has no subduction zones and this means the surface of the planet remains relatively old instead of being routinely resurfaced like Earth.In general Martian terrain features are many magnitudes larger than equivalent structures on Earth, for example the largest canyon on Mars is 11km deep, Vs the Earth's grand canyon at a mere 3kmMars features a type of geology not seen on Earth known as "chaos terrain", which seems to be caused by vast underground water ice deposits erupting out, carving IMMENSE river channels; often hundreds of kilometers long in very short time spans. Once the water source is depleted the surface collapses forming a crazed indentation in the surface, often kilometers deep.Since the martian surface has no rain nor plate tectonics to erode the surface features, and a thin atmosphere it bears numerous impact craters from meteorites.
What do valleys on the surface of a planet or moon suggest about previous land features?
The preses of water
What causes the changing dark and light features visible on the Martian surface from Earth?
the correct answer is highly cratered and eroded areas that are frequently covered and uncovered by dust
How strong is the Martian gravity?
At the surface, 38% of its value at the Earth's surface.
What dust covers the martian surface?
Iron oxide
What aspects of the martian environment might limit or affect the scientists' ability to do this kind of work outside on the martian surface?
Mars does not have a breathable atmosphere, which makes it difficult to work on the surface.
How do Martian meteors leave Mars?
Martian meteorites were ejected from the surface of Mars during massive asteroid and comet impacts.
What is the average temperature on the martian surface?
-23 degree celsius
What is the definition of surface features?
surface and features
Why was curiosity made with six wheels?
More stability on the rocky Martian surface
What was the first spacecraft to orbit another planet?
Mariner 9 took on that spacecraft's mission of mapping 70 percent of the Martian surface in addition to its own objective of studying changes over time in the Martian atmosphere and surface.
What was the mission of spirit and opportunity rovers?
Oppertunity's missions are to discover new martian rocks, map mars' surface, and to help scientists learn about martian weather.
Do low surface gravity help martian volcanoes grow to great height?
yes
