When did Mars lose its oceans? Billions of years ago, Mars was a warm home to lakes and oceans. That is, until these enormous liquid bodies on its surface vanished around 3 billion years ago. For years, scientists have assumed that this water disappeared into space when the planet's atmosphere thinned out.
Why doesn't Mars have oceans anymore?
This is different on Mars: the low pressure and low temperatures do not allow water to be stable in the liquid phase. Therefore, water on Mars is usually only stable as ice on the surface and as vapor in the atmosphere. There is much evidence that liquid water once existed on Mars, both of rivers and lakes or oceans.
Where did Mars water go?
But most of the water, a new study concludes, went down, sucked into the red planet's rocks. And there it remains, trapped within minerals and salts. Indeed, as much as 99 percent of the water that once flowed on Mars could still be there, the researchers estimated in a paper published this week in the journal Science.
Did Phoenix find water on Mars?
NASA has made strides exploring Mars in the past decade, including the discovery of water. Ten years ago, on July 31, 2008, NASA's Phoenix Mars lander confirmed the presence of water ice on Mars. Soon after, scientists at the University of Arizona confirmed it was water ice. Phoenix didn't stop there.
How did Mars lose its life?
Hence, more complex life forms were able to develop. However, tracing the Martian surface magnetic field indicated that Mars lost its magnetic field 4 billion years ago, leaving the atmosphere under severe attack by the solar wind.

What caused scar on Mars?
A ragged geological scar crosses the belly of Mars. Geologists think Valles Marineris began to open along geological faults about 3.5 billion years ago. The faulting was caused by the tectonic activity that accompanied the growth of the giant volcanoes in Tharsis, lying just to the west.
Which country found water on moon first?

Was the Phoenix Mars mission successful?
Phoenix was NASA's sixth successful landing on Mars, from seven attempts, and the first in Mars' polar region. The lander completed its mission in August 2008, and made a last brief communication with Earth on November 2 as available solar power dropped with the Martian winter.
