An Attempt to Get Survivors to Another Planet Is Futile

Australian astronomers are searching for planets in other solar system that could sustain human life. Dr Charley Linweaver says Mankind is reaching the beginning of the end. It's time to look for a way out at least for a small group of people.  The number of planets identified orbiting other suns now exceeds 750. Though a few of these could be like the Earth, exact information is lacking.

The objective of getting people to such a distant destination is way "off the planet" at present. We do not have the technology to get people in orbit around other planets in our own solar system, let alone reaching a far away planet and landing safely.

Finding an identical planet to Earth is just not possible. This planet is a freak in regard to the universe. Most planets do not have life because they are regularly hit by asteroids and even other planets. Sending probes to  a possible twin planet would be a waste of time. It would literally take a lifetime to get a message back.

There Is Soil on Mars

NASA scientists are now saying that "soil" on Mars could support vegetable life. Without an atmosphere, though, it seems no life is possible. Scientists are specific enough to say that asparagus and turnips will grow in Mars' soil but strawberries will not. Are they joking? Or are they for real?

The Phoenix Mars Lander found soil that is very much like that in many Earth backyards. Scientists are shocked that they have found soil. It is alkaline - thus, the claim that it is not good for strawberries. Apparently, the soil is rich in trace minerals.

My, how scientists can be wrong. It was thought that Mars "soil" would be salty - with no atmosphere and the sun would bleach it. But they were wrong. At least we know that there is soil and water in the form of ice just beneath the surface. There is evidence that in the past water flowed on the surface because erosion is evident. Rivers, lakes and oceans existed there once. Water reservoirs such as these indicate that the planet did once have an atmosphere.

If life did survive for a time on Mars future exploration will surely find it.
