The peak of Olympus Mons is 21,229 meters (69,649 feet) above the Mars areoid (a reference datum similar to Earth’s sea level). The lowest point is within the Hellas Impact Crater (marked by a flag with the letter “L”). The lowest point in the Hellas Impact Crater is 8,200 meters (26,902 feet) below the Mars areoid.
What is the coldest place on Mars?
On an average Mars day, the planet is about -81 degrees F (-60 C) – which yes, is much colder than Minnesota right now. But that’s just part of the range of temperatures on the Red Planet. During winter, temperatures near the poles can get down to -195 degrees F (-125 C).
What is the deepest point on Mars?
The crater depth is 7,152 m (23,465 ft) below the standard topographic datum of Mars.

What is the highest and lowest temperature on Mars?
In winter, near the poles temperatures can get down to minus 195 degrees F (minus 125 degrees C). A summer day on Mars may get up to 70 degrees F (20 degrees C) near the equator, but at night the temperature can plummet to about minus 100 degrees F (minus 73 C).
Is there low gravity on Mars?
The gravity of Mars is a natural phenomenon, due to the law of gravity, or gravitation, by which all things with mass around the planet Mars are brought towards it. It is weaker than Earth’s gravity due to the planet’s smaller mass.
Does Mars have oxygen?
Mars has only a thin atmosphere, with a surface pressure less than a hundredth of the Earth’s. Even worse, it is 96% carbon dioxide with only about 0.1% oxygen.
Can you breathe on Mars?
Mars does have an atmosphere, but it is about 100 times thinner than Earth’s atmosphere and it has very little oxygen. The atmosphere on Mars is made up of mainly carbon dioxide. An astronaut on Mars would not be able to breathe the Martian air and would need a spacesuit with oxygen to work outdoors.
What is the tallest 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.
Does Mars have water?
Almost all water on Mars today exists as ice, though it also exists in small quantities as vapor in the atmosphere. … Some liquid water may occur transiently on the Martian surface today, but limited to traces of dissolved moisture from the atmosphere and thin films, which are challenging environments for known life.
What is the largest canyon on Mars?
Known as the Valles Marineris, this huge canyon runs over 2,500 miles along the Red Planet’s equator, according to Brandon Specktor with Space.com. According to Specktor, “this gash in the bedrock of Mars” is three times deeper than the Grand Canyon, making it the largest canyon to be found in our solar system.
What is the warmest it gets on Mars?
Differing in situ values have been reported for the average temperature on Mars, with a common value being −63 °C (210 K; −81 °F). Surface temperatures may reach a high of about 20 °C (293 K; 68 °F) at noon, at the equator, and a low of about −153 °C (120 K; −243 °F) at the poles.
Is it cold on Mars?
Mars is very cold. The average temperature on Mars is minus 80 degrees Fahrenheit — way below freezing!
Is Venus hot or cold?
The average temperature on Venus is 864 degrees Fahrenheit (462 degrees Celsius). Temperature changes slightly traveling through the atmosphere, growing cooler farther away from the surface. Lead would melt on the surface of the planet, where the temperature is around 872 F (467 C).
Do female astronauts wear bras in space?
According to this Salon article[1], yes they do. They don’t need the support, but the bra keeps their wobbly bits in place while floating around in microgravity. They also like having an extra layer between said bits and the cameras all over the space station.
Can u get pregnant in space?
As a result NASA’s official policy forbids pregnancy in space. Female astronauts are tested regularly in the 10 days prior to launch. And sex in space is very much frowned upon.
What happens if an astronaut gets pregnant in space?
The primary problems with becoming and remaining pregnant in space are radiation and low-gravity environments. It’s important to understand both. Radiation can affect a man’s sperm count, rendering him infertile, possibly permanently. It can also harm a developing fetus.
