Technology that can get us to Mars does not exist, yet

Everyone talking how we will go to Mars soon. Guess again, we won’t, there is one big problem, Mars is pretty far away. We can’t go there, technology does not exist.

Mars is pretty far away

“It’s six orders of magnitude further than the space station. We would need to develop new ways to live away from the Earth and that’s never been done before. Ever.” Sam Scimemi,Nasa’s director of the International Space Station

Let’s put this in perspective, as we recorded Earth and Mars where the closest 34.8 million miles from each other. The farthest is 250 million miles apart. It’s important to notice that both Earth and Mars rotate over Sun, while for Earth it takes only 365 days to close the circle for Mars it’s longer. Mars goes around the Sun every 687 days.

How long should take us to go from Earth to Mars? Something between 150 and 300 days. If we check the history of traveling on that route, we will see the average time:

  • Mariner 4 (1965) — 228 days
  • Mariner 6 (1969) — 156 days
  • Mariner 7 (1969) — 131 days
  • Mariner 9 (1971) — 167 days
  • Viking 1 (1976) — 335 days
  • Viking 2 (1976) — 360 days
  • Mars Reconnaissance Orbiter (2006) — 210 days
  • Phoenix Lander (2008) — 295 days
  • Curiosity Lander (2012) — 253 days

We can’t bring with us all that we need

It’s not the same if in a rocket is robot or human. In order to stay alive in the space people need to eat something, they need to have a water, and oxygen. Also, there is a fuel, the rocket needs a lot of it just to get to the Mars. It’s double more for round trip. That is the main reason why is the trend one way ticket to Mars. There are no round trips.

Getting off from the Earth

A Mars mission would be on a much larger scale than almost anything we’ve done before, it’s not the same as regular mission. Still, there is no rocket that can take off from the Earth’s surface and escape its gravitational pull to reach space carrying the weight of a large spacecraft, astronauts and all the supplies and materials needed to get to Mars. Rockets would have to make several trips to drop off supplies and pieces for a vehicle into low-Earth orbit.

Then everything should be built in the space before a rocket could be ready to start a journey to the Mars. But, there is a problem with a fuel, objects in low-Earth orbit travel all around every 90 minutes. During half that time, they experience the heat of the sun. If objects are not well managed there is a big possibility that everything will blow up before the start.

Radiation make us problem too

In May 2013, NASA scientists reported that a possible mission to Mars may involve a great radiation risk based on the amount of energetic particle radiation detected by the RAD on the Mars Science Laboratory while traveling from the Earth to Mars in 2011–2012. The calculated radiation dose was 0.66 sieverts round-trip. The agency’s career radiation limit for astronauts is 1 sievert

But, we are trying to

It’s everywhere on the news, NASA, SpaceX and some other companies are trying to do it. They are trying to build a technology that will be able to bring people to the Mars. They are not trying to send us, yet. They just want to make an opportunity for it and prepare everything.

The future of technology is unpredictable

I guess we will find a way and send the human to Mars before 2030. You know what is the awesome thing about it? From 1930–2030 will just pass 100 years. In that 100 years human development increase from the point where we launched our first successful mission to space to the point where we are able to walk on the Mars surface.

It really seems to be like a movie. Next step is Mars, then we will discover alien civilization and then if we are lucky they will not colonize the Earth.
