Humans on Mars – My view on the Logic and Insanity

The concept of human colonising Mars isn’t new – it’s decades old and has been talked about since space travel started in the 1950’s and 60’s. Since the Moon landings the science community has viewed that travelling to Mars as being the next logical step in manned space exploration. The science and engineering behind this effort is staggering and while no actual missions are definitely planned in, the discussions have not ended and will carry on until we finally achieve this.

The way in which we travel to Mars has modified over time, I can remember when then missions talked about would last for some months on the Red Planet in order to make it worth the effort. I recent years though this has slowly changed to the realisation that missions to Mars are going to be one way only. You go to live the rest of your days there. This ties in nicely with the ethics of the colonisation of Mars, the preservation and advancement of the human race seems to be important right now. While I get this and there are those that have volunteered for this which is amazing, but do they really know what it’s going to be like? I’m sure a few months will be brilliant fun, but let’s face it 10 years down the line you might well have gone completely insane – if you haven’t starved to death.

Starvation and human preservation is kind of what brings me to some of the insanity around this. I’ve seen people talking about Mars being the next place the hum races goes to once we’ve finished ruining the Earth.

Seriously… WTF?!?

Do you seriously think that it’s all going to be ok to plunder the Earth until it’s a wasteland and then park up on Mars? When was the last time you saw this place?

This is it. It doesn’t change much. Nothing grows here, there is no atmosphere to breathe despite what science fiction movies tell us (it’s called fiction for a reason). If we reduce Earth to a wasteland we won’t find anything better on Mars. Colonising Mars is a huge step towards human living permanently off Earth but it’s not a second option to Earth. Earth must be preserved!

The other insane idea is that of Elon Musk’s to create a martian atmosphere by detonating nuclear warheads at the poles, melting them and creating an atmosphere. This is so flawed it’s not funny. Mars has a tiny magnetic field, so it cannot keep much of an atmosphere. But even if it could – everyone would be breathing radioactive air for the next 1000 years! There is also his vision to make travel to Mars accessible to all, costing around $200,000 a trip.

As in every huge project, there is insanity that rides with it. Travelling to Mars is going to be expensive. Living on Mars will be even more expensive and will be very hard! The rewards could be unimaginable and ultimately so will the costs.

Scary look at Earth’s dwindling resources

Most of the resources we have on Earth cannot be replaced. We’re often told in the media about how this or that is running out. This graphic shows a sample of the resources we’re using – it’s interesting and a little scary.

Seasons -How are they worked out?

One of the things that’s always puzzled me is when each of the seasons are supposed to start and end. This is typical of someone that over thinks things, really it should be when it’s cold and wet it’s Winter, when the flowers start appearing and the wet is thawing out it’s Spring. Summer is the season of sun, interrupted by heavy rain, with Autumn being the time when one picks blackberries and apples – yup, you guessed it, in the rain!

But when are each of these season’s really supposed to start and finish? I’ve looked at this and there are at least two versions, the meteorological and the astronomical seasons.

 

Meteorological Seasons

The meteorological seasons are divided up by meteorologists to make weather forecasting easier. The seasons dates are split up as such:

  • Spring – from March 1 to May 31.
  • Summer – from June 1 to August 31.
  • Autumn (Fall) – from September 1 to November 30.
  • Winter – from December 1 to February 28 (February 29 in a leap year).

 

Astronomical Seasons

The astronomical seasons are a little different.

Spring starts at the March equinox, this is when the length of night and day are almost equal. This happens on either the 19th, 20th or 21st of March. At this point the Sun is directly over the equator.

Summer starts in the June Solstice, this is the longest day in the Northern hemisphere and the shortest day in the southern hemisphere. This normally between June the 20th – the 22nd.

 

Equinox and solstice illustration.

The September equinox heralds the arrival of Autumn and is the date that again night and day are about equal and this happens on the 22nd, 23rd or 24th of September. This is where the sun is directly over the equator.

This lastly leaves the December solstice, where the shortest day of the year takes place in the Northern hemisphere and the longest day in the southern hemisphere. This takes place between the 20th – 23rd of December.

The seasons are of course opposite between the northern and southern hemispheres as the tilt of the Earth defines the seasons and will be opposite between the north and south.

ISS: Air and Space Science

The ISS is a big floating laboratory in space, helping us to find out things that help is physics, biology and every other branch of science in between. They also have a good place to see what’s happening here on Earth.

This Tumblr post from NASA show us some of the work they’re doing.
