Hubble snaps photos as Mars makes its closest approach to Earth

It was a process of three years held by the European Space Agency's Mars Express spacecraft which resulted in the finding of a 1.5 kilometers thick and 20-kilometer-wide water boy having its placement at the southern pole of the planet. Does that promise hope for human immigration to Mars in the future? While previous images showed detailed surface features of the planet, this new image is dominated by a big sandstorm enshrouding the entire planet.

When is the best time to see Mars?

To be clear, there's no sign of any actual Martian microbes swimming around, and the environment is not obviously hospitable - the water at the base of the polar cap is estimated to be minus 90 degrees Fahrenheit, far below the typical freezing point of water.

"The radar profile of this area is similar to that of lakes of liquid water found beneath the Antarctic and Greenland ice sheets on Earth, suggesting that there is a subglacial lake at this location on Mars", said the report. These features were interpreted as due to the propagation of the radar signals through a very cold layer of pure water ice having negligible attenuation.

"It is odd that SHARAD can not confirm this discovery". So what a combination of previous claims by Ojha and new claims by the Italian scientists means is -that there could be sufficient water on Mars which could have gone undetected in previous surveys.

"The distance between the Earth and Mars is shorter than it normally would be", said Mackay. Hubble even has one advantage over these probes: it can look at these objects periodically and observe them over much longer periods than any passing probe could.

For a long time, scientists have been extremely interested in the red planet. With the support of NASA, some USA private companies have even been thinking about plans for immigration to Mars.

These side-by-side images of Mars, taken roughly two years apart, show very different views of the same hemisphere of Mars.

The ISA declared their discovery on Wednesday, but they have been working on that for about six years.

That's of tremendous meaning to humans, because it makes long-term survival on Mars possible. "These natural resources will be invaluable when we send people up there".

Scott Hubbard, a professor of astronautics at Stanford University who served as NASA's first Mars program director in 2000, called it "tremendously exciting".
