Why do scientists think there might be life on earth like planets when aliens might survive hot temperatures with no water?

Good point. Great question. We just look for the most “likely” places life might develop. Interestingly, though, there are lifeforms like the ones you describe here on Planet Earth!

You can find these lifeforms in Chile, specifically the Atacama desert. This place is burning hot and has had no significant rainfall in at least 250 years.

According to express.co.uk “While in the central valleys [of the Atacama desert], researchers found 70 species of microorganisms and further inland, the team made another shocking discovery.” What they found, 1 meter deep, was actual living bacteria.

Life does exist in extreme conditions sometimes on Earth. Why not elsewhere, like Mars for instance?

So far, however, we haven’t found any life or former evidence of life, anywhere except here on Earth.

It leads us to believe that if life is out there somewhere, the most likely place to find it would be in conditions that are similar to various climates and places on Earth.

Is it possible for a planet, such as Mars, to develop a liveable atmosphere on its own? What would it take?

Elon Musk’s Automobile to be put in Orbit around Mars


This rather large SpaceX rocket is called the Falcon Heavy. Inside is the automobile below, which SpaceX hopes to launch in orbit around Mars with a flight schedule February 6, 2018 (assuming it doesn’t blow up on the launchpad).

You just can’t make this stuff up. The automobile, which belongs to the founder of SpaceX Elon Musk, is a Tesla Roadster. If successful, the automobile could stay in orbit around Mars for a few billion years. The car will just be let go to float on it’s own ’round and ’round Mars.

I guess that’s in case you ever need to catch a ride to orbit Mars!

Planetary exploration to Mars will bring new policies. For example, maybe even a new constitution on Mars. What would be yours for the new colonization of Mars?

This hypothetical question doesn’t take the harsh realities described below. You begin by saying planetary exploration to Mars will bring new policies. Maybe here on Earth, like what we have in Antarctica, for Mars. The Chinese are likely the first ones to send a manned mission.

In my pessimistic and realist point of view, Mars will never have a human civilization living on it. I almost get tired of saying it over and over again. Mars cannot be terraformed. It is too small and has no organized magnetic field to shield from harmful rays of the sun. Too small means too little gravity, which means to have enough atmospheric pressure for humans would require a much thicker atmosphere than Earth because things, including atmosphere, weigh less on Mars. Because it’s so small, however, it doesn’t have the gravity to hold such an atmosphere and the unhindered cosmic rays from the sun would just blow it away into space.

Mars is not very hospitable and is very, very far away. We may one day have human footprints on Mars, although that is not necessary and very dangerous just so we can say we did. Pretty much everything we want to find out about Mars can be done by our rovers and future rovers.

Could humans specialize in terraformation? If we focused on increasing our knowledge of planet habitability, and the methods of terraforming, could our species be known as ‘terraformers’?

Could we specialize in terraformation? It would be nice.

Unfortunately, focused or not, terraforming is not realistic. Look at Mars. The problem is not creating an atmosphere. The problem is keeping it and protecting people there from dangerous rays from the sun. You see, Mars has no organized magnetic North or South. Without a magnetic field the people there would die of exposure. Furthermore, without sufficient gravity to hold in the atmosphere, it would blow away by rays from the sun. Mars simply cannot be terraformed. It doesn’t matter whether you focus or not.

Will the moon or Mars have the first permanent human population?

In my opinion, hopefully neither place because there is no valuable reason for humans other than our robots to establish a presence in either place. Robots are expendable and you don’t have to bring them back. They can transmit what they find. Both are dead planets. Both have no reason to settle there.

Weird

Okay. I admit it.

I confess.

This is a weird blog. It’s my blog and I post whatever I want on it and I get, for some reason, a whole lot of traffic.

I post about weird stuff. Space. Occasionally politics. Life and death stuff. Philosophy. Linux. Weird stuff. At all times of the day.

Now I want to tell you about Cassini–Huygens. It’s an unmanned spacecraft sent to the planet Saturn. It is a Flagship-class NASA–ESA–ASI robotic spacecraft. Cassini is the fourth space probe to visit Saturn and the first to enter orbit, and its mission is ongoing as of April 2017.

That last paragraph was mostly plagiarized which I can do. Sue me.
