Ever since we started exploring space, we have been wondering … does extraterrestrial life exist? And what is one of the main signs of life? Water. Another form of water? Ice. Where is water? Mars.
Before we get to the exciting part, let’s discuss, why go to Mars?
Well for starters, it’s close. It's one of the two planets right next to us, and its temperature isn’t too crazy cold and isn't a fiery hellscape. Mars is cold, but after all, what's the one thing humans are good at? Making planets warm! Another reason is that it is a candidate…
Disclaimer: It was (much) harder than I envisioned.
What's stopping us from exploring space?
First, let me emphasize cost.
Space travel is the most expensive yet crazy kind of transportation; like how skydiving is in sports. Wait, but in the grand scheme of things though, rockets seem simple. After all, the first one was made in 1100 AD before even electricity which was invented 700 years later and I learned how they work in physics class in middle school. Easy right?
… I wish.
The Voyager 1 and 2 probes travel in places never reached before by humans and continue to travel at extremely high speeds out into the unknown galaxy… but what have they done and where the heck are they?
Launched in 1977, their original mission was to explore Jupiter and Saturn. After making a collection of discoveries, Voyager 2 went to explore Uranus and Neptune and is the only spacecraft to have traveled to those outermost planets of the solar system. Now, the Voyager Interstellar Mission will explore the outskirts of the sun's field. …
You generally don't want to be blasted to space atop a 200-foot metal cylinder filled with 549,000,000 grams of “some type of” highly explosive propellant. So let's get to know it a bit.
Space Agencies can’t be using jet fuel to propel their rockets … right??
Well, they definitely don’t just go to jet fuel suppliers and use that for their rockets, but what they do use is something very similar. They use RP-1, or Rocket Propellant 1. Both Jet [Fuel] A and RP-1 are highly refined kerosine, but technically RP-1 is understandably more refined, as you would hope.
Is it a galaxy, a star, a planet, a soccer team or what?
If you’ve been reading up on space technologies, you may have heard the name Alpha Centauri before. Here, I will give you a short summary of the basic facts about the star system, just enough so you go from not knowing what you are talking about to sort of not knowing what you are talking about. I will also touch on what this all means.
It is the closest star and star system to the earth and contains three stars (wow). Alpha Centauri A, Alpha Centauri B…
