A new movie due out soon, Interstellar, is supposed to present space travel in a way that will make people sit up and take notice.  Well, we’ll see.

It has to be better than the nauseatingly frequent run of Zombie Apocalypse movies and TV shows, which seem to be mostly just excuses to show people blowing other people away in hundreds of different gruesome ways.IMG_0344  We can look at zombies in the same way that soldiers have to look at the enemy so he can be killed without remorse.

Space Program As Important As Any Poverty Programs

Destination: Mars

The problems of poverty and disease may take care of themselves sooner or later, according to SpaceX founder Elon Musk.  But that will be because of nature’s “carelessly terrifying violence”, not for anything we do.

He says we have all our eggs in one basket–we live on only one planet and that’s not a good thing.  It’s a terrible risk management strategy. That makes space exploration as important as any poverty program because it will get some of us off Earth where we can survive if anything happens to the home planet.

Nature can be extremely violent.  We haven’t experienced its full violence yet because we’ve only existed for a very short time in cosmic history.  In that sense, an extinction level event would solve all our problems, but there wouldn’t be any of us left to celebrate.

Musk thinks there may be a whole lot of dead, one planet civilizations in our galaxy alone which ought to be teeming with life. He offers this as one explanation for why we haven’t discovered any intelligent life so far.  Violent cosmic events such as gamma ray bursts, asteroid strikes, extreme volcanism, or species suicide events may keep civilizations from developing much beyond the stages we are at now.

Musk says he doesn’t intend to stop with just developing vehicles to get people to the international space station.   His intention is to found a colony on Mars.  His Mars One plan will send the first humans to Mars.  Over 200,000 people have applied for the one way tickets so far.

Before we can live even semi-comfortable lives on other planets or moons, more advances in science and technology will need to take place.  We will need the ability  to terra-form Mars, to hollow out asteroids, to protect space farers from dangerous radiation, and to provide unlimited 100 per cent reliable power supplies for electricity, heating, and oxygenating whatever environment we choose to live in.  There is water on Mars, which can be used for providing  fuel as well as drinking, but it may be difficult to get at in any easy abundance.
