What is the temperature on Hellas Planitia?
At 90 degrees longitude, the estimated atmospheric pressure is above 5.5 millibars, suggesting the presence of a high-pressure area. The temperature on the east side of this air mass is about -70 degrees F, while it is 20 degrees warmer on the west side.

What is Hellas Planitia and how did it form?
A color image of the Hellas Planitia region of Mars; north toward top. The scene shows the Hellas plain within the 1,800- km-diameter Hellas basin, an ancient impact basin (and the largest basin on Mars) formed when a large projectile (asteroid, comet, meteor) hit the surface.
How many volcanoes are on Mars?
Mars today has no active volcanoes. Much of the heat stored inside the planet when it formed has been lost, and the outer crust of Mars is too thick to allow molten rock from deep below to reach the surface.
What is Space Hellas?
Hellas, enormous impact basin in the southern hemisphere of Mars and the planet’s largest recognizable impact feature. Centred at roughly 40° S, 290° W, Hellas measures about 7,000 km (4,400 miles) across, including the broad elevated ring surrounding the depression, and 8 km (5 miles) deep.
What is the tallest thing on Mars?
Olympus Mons
Olympus Mons is the largest volcano in the solar system.
How tall is the biggest volcano on Mars?
The largest of the volcanoes in the Tharsis Montes region, as well as all known volcanoes in the solar system, is Olympus Mons. Olympus Mons is a shield volcano 624 km (374 mi) in diameter (approximately the same size as the state of Arizona), 25 km (16 mi) high, and is rimmed by a 6 km (4 mi) high scarp.
What gives Mars its reddish look?
Well, a lot of rocks on Mars are full of iron, and when they’re exposed to the great outdoors, they ‘oxidize’ and turn reddish – the same way an old bike left out in the yard gets all rusty. When rusty dust from those rocks gets kicked up in the atmosphere, it makes the martian sky look pink.
