The heat from the soils and the atmosphere interact, drawing the dust up and creating a swirl. This dust plume is more than half a mile in height and about 30 yards in diameter. When they landed more than 10 years ago, the Spirit and Opportunity rovers were designed to last 90 days, because it was predicted that dust would settle on their solar panels. Opportunity has been kept clean by dust devils for the last 11 years.

Spirit got stuck in a sand trap in , and eventually ran out of power. Early in its mission, the Spirit was hit by another aspect of weather featured in The Martian: a gigantic dust storm. These storms feature in the book and movie too, though in this case, the narrative takes some dramatic liberties with the science. This artists concept illustrates a Martian dust storm, which might also crackle with electricity. Photo by NASA.
Another shocking feature is the lightning.
Watney turns the Hab into a greenhouse to grow food and even develops a system to create water.
As these dust storms pass by, we can actually see lightning strikes, Green said. But the color of these flashes might be slightly different from what we see on Earth, since the composition of the Martian atmosphere differs from ours. It not only captures satellite observations, but creates global weather maps of Mars, akin to what you might see on a nightly news program. Is Mars the next best home for humanity?

I asked both Weir and Green to weigh in on the colonization question. Suppose humans wanted to colonize outside of Mars — where in the Solar System should we go? Such technology is already being used on the International Space Station. Plus, it has giant lava tunnels near the surface where we could build a base that could house the entire city of Philadelphia. The city of Philadelphia is shown inside a theoretical lunar lava tube. Earlier this year, researchers from Purdue University explored whether lava tubes more than 1 kilometer wide could remain structurally stable on the moon.
The moon gets very hot during the day and very cold at night.

But inside the lava tube, it would maintain a very constant temperature. To be fair, a human hive on Venus or these moons would all require one thing: a massive amount of futuristic technology. A Mars colony, on the other hand, is feasible within the next couple of decades , Green said. Consider the resources there. The saltiness of flowing streams announced on Monday might make this water source as toxic as a Superfund site , but Green said water in an underground aquifer might be cleaner. Humans will go expand and live anywhere. People live in the Sahara.

Though Mars is the third largest of the four terrestrial planets by volume, it houses the largest peak in the solar system by a wide margin.
Olympus Mons has an area nearly as large as Germany, and reaches Olympus Mons is still believed to be active, along with the other nearby Tharsis Montes volcanoes, a trio of shield volcanoes each two to three orders of magnitude larger than any found on Earth.

The valleys extend as deep as seven kilometers into the planet, and are believed to have formed from tectonic and volcanic activity in the nearby Tharsis region.

But as cameras get sharper and return higher-definition photos, it becomes clear that sometimes we only see what we want to see. That said, there are still plenty of mysteries left on the Red Planet.

Water and the martian landscape
