Hello there!
In this post, I want to tell about rocket
The Falcon 9 but what's so special about it? Well, I won't hold it for a long time - it's a partially - reusable launch system.
Okay, so It's just another rocket, which you can use over and over, you can say. And my answer will be "yes", but hold on a sec.
I think you have already watched this short clip and you know the answer. So fully the answer would sound like: "The Falcon 9 is a family of a Launch Vehicles, the first stage of which is reusable and can land vertically.
Now I'm going to run through details.
Economic aspect
Let's begin with numbers. For 2016 year is being announced 16 launches. Each "Falcon" launch cheaper 30% (price drop from 61,2 million to 42,8 million). So, for only one year it's possible to save 480% of the first stage price. This is the most powerful benefit of this program.
Science
The main task of "Falcon" is the delivery of goods to the International space station. Which orbit is approximately 25'000 miles above Earth. Landing platform can be located 4 miles to more than 300 miles from the launch place. One of the biggest challenges was to find the way to keep rocket stable during landing. One of the faced problem's was that engine can't give partial impulse because it's so strong that will push rocked up in seconds. Scientists decided that the best way to solve this problem is to leave the amount of fuel necessary to slow rocket to the zero speed right before it touches the ground. Just imagine how much calculations they made!
Prestige
Engines for "Falcon" were designed and constructed in the United States . This fact makes the USA more independent from Russian "Soyuz" rockets and also make America lead in space and technology race with Russia.
After all, it looks soo cool! And make a the human dream to reach the stars even closer!
Thanks for reading!
