Thinking about the future

Today I’m looking at how NASA is taking advantage of the movie “Passangers”, to explain future methods of sending probes out of our solar system.

This problem, as they indicate, comes from Voyager probes, those that are, at the moment, the human apparatus that has arrived more far.

As they indicate, the most important part is to know “that there is” outside the solar system. That is, you can not send anything out of the solar system if you are not clear what is out there (which is not empty, by the way). Something that we are a bit green now. When I say “there is” it refers to electromagnetic emissions, photon currents, magnetic fields …

For this, the probe Voyager 2 (the one that is further from the two) is our spearhead. Although this old one and its sensors are not of the other world it continues giving vital information … with the little battery that it is left and the cold that is happening. You know, you can use the old topic of “do not do things like before” although that mission was in mind for this need.

Next, after “knowing that there is out there” is how we can take advantage of everything we have as energy. Because in this universe energy is very important. The potential difference is what makes things move. So it is convenient to know where we can draw energy and how to use it.

Maybe that’s why, from what we know now, NASA is thinking about the old method of slingshot, but a little more advanced. If we now use the gravity of the planets to accelerate and throw things, we may be able to use the gravity of the Sun outside the solar system, that is, use the entire solar system as a gravitational motor.

NASA explains the amount of gravity a solar system generates through gravitational lenses. As you know, because it explains, a gravitational lens is no more than the curvature that takes light due to the gravity of the whole of a solar system.

In “advanced” mode (currently) is to use optics, since we know, from our perspective, what is the focus of said lens and therefore the maximum point of such gravity as a gravitational “impulse.” It’s a very interesting concept, old, but interesting.

The next thing is to link this to hybrids of different types of engines (some of a lot of energy and little time to others of little energy and a lot of time) in order to get accelerations and speeds … fast. Since, the only thing that is clear is that with chemical engines … we did not arrive.

As you see, humanity advances and if before the dream was to go to the Moon, then go to Mars, and is thinking of the next logical step, go to another star, even one of the closest (Alpha Centauri).
