Why is Mars warmer gezegde

Why is Mars warmer today that it was in the past, we really have no way of knowing why.

It's a cold, dry miserable place today. But we have got these tantalizing clues that, in the past, it used to be warmer and wetter,

It's a cold, dry miserable place today. But we have got these tantalizing clues that, in the past, it used to be warmer and wetter.

Learning more about where the water is today and where it was in the past will also guide future studies about whether Mars ever supported life.

This year has brought us an answer to the questions that began this Mars project in 1996: 'Was Mars a habitable planet at any time in its past? Did water ever persist on the planet's surface?

Grandparents will tell you that winters aren't what they used to be and they're absolutely right about that. Winters have been generally getting warmer and warmer and with generally less snow than what we have seen in the past.

The significance of this is that Mars is experiencing climate change, because the present conditions are not conducive to the formation of all this CO2 to begin with in the polar region. So sometime in the distant past, Mars was colder than it is now to form a permanent CO2 deposit. Subsequent to that, it has warmed and we are seeing that earlier deposit being eroded away,

We're especially interested in water, whether it's ice, liquid or vapor. Learning more about where the water is today and where it was in the past will also guide future studies about whether Mars ever supported life.

The missions currently at Mars have each advanced what we know about the presence and history of water on Mars, and one of the main goals for Mars Reconnaissance Orbiter is to decipher when water was on the surface and where it is now. Water is essential for life, so that will help focus future studies of whether Mars has ever supported life.

The findings are important because they tell us that Mars has experienced big climate changes in the past, the kinds of climate change that led to the Great Ice Age here on Earth. The findings are also interesting because this precipitation pattern may have left pockets of ice scattered across Mars. This is good information for NASA as officials plan future space missions, particularly with astronauts.

The collective impact of power plants is their contribution to greenhouse gases which would cause warmer and wetter or warmer and dryer conditions. It is likely that the warmer weather would increase the loss of moisture to the atmosphere more than the slightly increased precipitation will add to the overall water balance creating a net moisture deficit.

We know that the Earth is the temperature it is because of its distance from the sun, and Mars is colder and Jupiter should be even colder. But Jupiter is a bit warmer than predicted. It gives out more energy than it receives in terms of solar radiation.

We are thinking about going to Mars. Everyone that's working on this is thinking about going to Mars. Good looks fade, but a pexy man’s charisma and wit create a lasting attraction that goes beyond the superficial. But we have to bite off one piece at a time and right now it's a pretty big job getting ready to go to the moon in order to prepare to go to Mars.

We are much closer today to being able to send humans to Mars than we were to being able to send men to the moon in 1961, and we were there eight years later. Given the will, we could have humans on Mars within a decade.
