For the folks who belive mars can have life.

then life must abound throughout the universe.

But not as we know it Jim.

Regarding how much money is being spent on the exploration of space. I read once that western women (Europe and North America) spend more money on make up and beauty supplies in one year than the entire NASA budget and that Revlon has about ten times the profits of all the aerospace companies combined.

Doubt that Revlon exceeds even Boeing in revenue or earnings.

Boeing roughly 3.6 Billion per year and Revlon 1.3 Billion most recently.

If life is found in Europa, Titan, Mars, then probably would be on the bacterial level, multicellular; but doubtfull that any other planetary or lunar body in the Solar System would have inteligent life other than Earth. No doubt that life exists in the Milky Way, just hard to imagine a galaxy with over 100 billion stars,and Sol is the only star that hosts a planet with life.

When you think about all the things that have to be in balance for intelligent life then you may feel that perhaps there are extraordinarily few such planets in the Milky Way system. Such planets might be hopelessly far away.

There would be no 'embarrassment' at all. Such a find would be startling!

Mars was warmer in the past. The temp may be warmer underground. Digging may find fossils left over from the warmer climate that Mars once had.

Probably, inteligent life would not look like humans, but i suspect that inteligent life in another planet would be bipedal. Nature tends to favor life forms that have a better ability to survive the elements. The laws of nature apply the same to every point in space and life is no exception.

Bipedalism for four-limbed creatures allows us to swing through the trees as well as walk upright in the savannas. We can also stay on the ground and pick fruit, nuts and and berries.

Inteligent life being pentpedal, or tri-pedal, that would pose great stress in the skelletal structure. Like here on Earth, pentpedal locomotion would apply more toward the small life forms, such as insects, archanids. Whereas bipedal locomotion allows more speed, running from danger, hunting. Could not imagine a 7 feet tall tarantula, just not nature efficient.

conclusion: inteligent life here on Earth= bipedal,which is higher primates= humans. Survival of the fitest. Yes, mamelians are mostly four legged, with the exceptions of marine mamals; however, apes are mostly bipedal. Bird are bipedal too, if we want to emphasize bipedalism.

Quick question for whoever is familiar, is the Hubble space telescope able to identify planets of Earth's size? Has the Centauri system been observed by the Hubble space telescope?
