The environment of Mars contains dust that is much finer than that found on Earth. While the exact effects of this fine dust on technical hardware and equipment are not fully known, it is not impossible to engineer equipment to survive it. The NASA rovers Spirit and Opportunity were designed to operate for a minimum of 90 days, but have exceeded their target lifespans substantially. Spirit lasted about 1900 days. Opportunity is still driving around and investigating Mars since January 2004.
It is unknown how the fine Mars dust might affect humans, should they be exposed to it. However, the astronauts will only go outside in their fully-enclosed Mars suits, and inside the habitat, the air will be filtered to remove the dust.

Balloons provide a unique vantage point for scientific observation. Balloons can fly one hundred times closer to the surface of Mars than orbiters and can travel a thousand times further than rovers in a comparable period, thus providing views of much broader areas of the surface.

The air on Mars would kill a human quickly. The atmosphere is less than 1% of Earth’s, so it would be hard to breath. What you would have available to your lungs would be undesirable to say the least. The air on Mars consists of 95% carbon dioxide, 3% nitrogen, 1.6% argon, and the remainder is trace amounts of oxygen, water vapor, and other gases.

"If humans go to Mars and have a similar positioning system there, knowing about ionosphere effects will be important," Withers said.

Mars has a thin atmosphere — too thin to easily support life as we know it. The extremely thin air on Mars can also become very dusty. Giant dust storms can blanket the entire planet and last for months.
What is Mars' atmosphere made of?The atmosphere of Mars is about 100 times thinner than Earth's, and it is 95 percent carbon dioxide. Here's a breakdown of its composition:
- Carbon dioxide: 95.32 percent
- Nitrogen: 2.7 percent
- Argon: 1.6 percent
- Oxygen: 0.13 percent
- Carbon monoxide: 0.08 percent
- Also, minor amounts of: water, nitrogen oxide, neon, hydrogen-deuterium-oxygen, krypton and xenon

1. It's the longest system of canyons in the Solar System, at over 4000 km long. If you were to drive a car at 100 km/h (60 miles per hour), it would take you over 40 hours to drive the length of Valles Marineris. It would be like driving from Madrid to Moscow.
