Is there any air on Mars?

Question

If not,when we send our probes to Mars how do they parachute to the surface?

Answer 1

Parachutes do work on Mars because it does have air, although it's very thin compared to Earth's atmosphere--only about 1% of Earth. Also, spacecraft landing by parachute on Mars don't have the higher velocities to deal with because Mars's gravity is much less than Earth. 95% of Mars's atmosphere is carbon dioxide, the rest argon. There is no oxygen in Mars's atmosphere.

Answer 2

Mars has a very thin atmosphere made mostly of carbon dioxide. The surface pressure on Mars is only about 0.7% of the average surface pressure at sea level on Earth. Also, the atmospheric pressure on Mars changes seasonally because the temperature is cold enough that some of the carbon dioxide freezes during the winter and "snows" onto the polar cap. This greatly reduces the amount of carbon dioxide left in the atmosphere. During the summer, when the polar cap warms up again, the carbon dioxide goes back into the atmosphere. Compare with Venus's atmosphere.

Mars also has a lot of dust in its atmosphere, and winds occasionally create large dust storms. Dust devils, which are like miniature tornadoes are very common and have been photographed by spacecraft on the surface.

The comparatively large amount of carbon dioxide in the Martian atmosphere – 9 times more overall than is contained in Earth's much thicker atmosphere – led astronomers to conclude more than three decades ago that the Martian atmosphere should contain small amounts of water vapor and hydrogen. Why? Because the carbon dioxide would be split by solar radiation into carbon monoxide and oxygen; water vapor must be present, the theory went, to trigger chemical reactions that recombine the carbon monoxide and oxygen to make carbon dioxide and thus complete the cycle. As part of this process, hydrogen molecules would be created. Water vapor was found on Mars by Viking in the 1970s, but the molecular hydrogen was only detected as recently as 2001 by Vladimir A. Krasnopolsky of the Catholic University of America and Paul D. Feldman of Johns Hopkins University, using NASA's Far Ultraviolet Spectroscopic Explorer (FUSE) spacecraft.

Answer 3

it depends on what you call "air". The air on earth is not actually a gas, it's a mixture of other gases. 78% nitrogen, 21% oxygen, carbon dioxide, methane, argon, etc. Mars does have an atmosphere, but it is mostly carbon dioxide. So yes Mars does have "air" but we couldn't breathe it. A parachute or plane will work in it though, just like on earth.

Answer 4

The atmosphere on Mars is extremely tenuous, about the same as the atmospheric pressure over a hundred thousand feet above the Earth's surface. Also, its composition is mainly carbon dioxide and therefor not breathable. The density is just enough to support a large enough parachute, and to produce enough wind to create dust storms. These are also helped by the fact that the gravity is only about one third that of Earth.

Answer 5

Very little, No Nitrogen or Oxygen, mostly Carbon Dioxide. Mars' gravity is insufficient to retain an atmosphere, so it drifts off into space. Colonists would have to create Bucky Domes and generate oxygen from plant life within them and wear space suits outside them. Pretty spartan living conditions,

Answer 6

LIke that guy said, the atmosphere on Mars is mostly carbon dioxide. That is also why they get massive sandstorms on Mars as the wind lifts the sand into the atmosphere.

Answer 7

There is an atmosphere, but it is mostly things other than "air", such as CO2, etc. Also, it is a very thin atmosphere. Parachutes do work, but not all that well.

Answer 8

no

Answer 9

no
