Ha ha, cool.

Sometimes I want to stay in at night and look at the sky. After all, at this moment somewhere far away, Voyager leaves the bounds of the solar system. This is great.

The sky is the greatest show in the universe. 
For some time I have wanted to build my very own Newtonian reflector telescope, starting with grinding and polishing the primary mirror, so I can get a closer look at the planets, stars, nebula, and distant galaxies with an instrument I built myself. This was not such an uncommon thing in the past when the only way to obtain a telescope was to have it custom made- an option available only to the rich- or to build it yourself. These days amateur telescope making is mainly the province of self-described "Telescope Nuts" (TNs) who continue pushing the envelope with what can be achieved by "pushing glass" just for the fun of it. Building a telescope will take a lot of time, patience, and some materials and equipment that I don't have at the moment. But someday I hope to do it. (:
It gives me an odd feeling to look up at the night sky and realize that those twinkling lights and hazy nebula are the domain into which we humans will someday travel, but only if we have the courage to venture into the unknown abyss of space and the wisdom not to destroy ourselves with our own technology...

I had a similar idea. I wanted to save money and buy. Later I figured out what is a complex instrument, and that a good telescope will cost a lot of money.
I did not get to assemble such a device. But sometimes in my town in the day of Cosmonautics, on the main street put telescopes and anyone can see the stars and nebula.
I, too, believe in it and hope.

Yeah, telescopes can be quite expensive instruments... especially if you want a large one. Building can be a less expensive option, especially for larger size instruments and those who are good at scrounging useful parts from junk heaps. All the same, the real reason I want to build a telescope is for sheer fun of learning all the new skills required for mirror making and telescope building.
Only sheer chance led me to discovering the world of telescope making. I stumbled on the mirror making page of the Springfield Amateur Telescope Makers and was utterly fascinated by what I read. I hadn't ever known that such a precisely ground surface could be made at home using simple materials and hand labor- even made on a kitchen table! Someday I hope to try this myself, though I have not had the opportunity yet.
There is a Day of Cosmonautics in Russia? That is very cool! We don't have any similar official holiday in the US, sadly. 
Sidewalk astronomy is a great activity! I believe that our local astronomy club organizes such events in a local market's parking lot from time to time. The "yard cannon" Dobsonian mount for Newtonian reflectors was originally designed by the late John Dobson (who just recently passed away Jan. 15, 2014) as an easy-to-make "sidewalk telescope" for setting up on sidewalks and showing everyone the wonders of the night sky.
We seem to have avoided destroying ourselves so far. We just need to remember that humans need more than just the "necessities of life"- we need ever-expanding horizons to pique our curiosity and drive us to explore the limitless possibilities the universe provides. Whether we delve into the microbiology of a flea's cell, probe the far corners of the galaxy, or explore the limits of our imagination by drawing or writing- we are all explorers at heart.

I know how to repair motorbikes ,but building telescope in home ...
it's difficult
In Russia Day of Cosmonautics celebrated on April 12. First manned space flight made on April 12, 1961 by the 27-year-old Russian Soviet cosmonaut Yuri Gagarin. It is an official holiday. But now it not celebrated how in USSR. On this day, various exhibitions and events, but to attract young people today is very difficult.
In Russia not so many people are addicted to the space industry, but everyone knows that Yuri Gagarin the first man in space and Neil Armstrong the first man on the moon.
I agree with you.I couldn't have said it better.

I agree. I have a question, is it the optical aspects of telescope making (grinding the mirror, aligning the optics, etc.) that you consider the most difficult or the mechanical aspects (building the tube, mount, mirror cell and so on)? I have read that many people are confident making the mechanical parts of a 'scope but intimidated by the thought of fabricating the optical elements. I was the opposite way... the optical fabrication side of telescope making is clearly explained in books, but I found the instructions on building the mount and tube harder to understand because I lack experience in woodworking and mechanical skills in general. I would like to learn, though.
We have the same problem in the US. Attracting young people to STEM education and space travel is not easy... but sometimes the inherent excitement of these topics can attract interested people. The real problem is that many people seem to think that the cost of space travel is not justified, even though the returns are great and NASA's budget is much smaller than most other absolutely vital areas of science (biology, medicine, etc.) and defense spending. One can only imagine what could be accomplished if the people of the world could agree to unite in the effort to explore the cosmos instead of building weapons of destruction to threaten each other with down here. So many things seem utterly practical and necessary to politicians here that just begin to seem utterly nonsensical when seen from up there... guess that is what is meant by the Overview Effect. Maybe someday leaders will be taken out beyond the Moon, where the Earth shrinks to a small blue-white marble, and be told to contemplate just what this view means before they are permitted to take office.
Oh, and in addition to knowing that Yuri Gagarin was the first man in space and that Neil Armstrong was the first man to walk on the surface of the Moon (accompanied by Buzz Aldrin while Michael Collins waited in the orbiting Apollo capsule for their safe return), I always knew that Valentina Tereshkova was the first woman to fly in space on the 16 of June, 1963!! She was also the first civilian to fly into space. I consider that an important space first to remember.

I think the creation of the telescope will take a long time. I finished studying at the institute in 3 months. I studied at the political scientist . But I want to work as an illustrator . Difficult situation . I think can make a telescope when my life will have more free time , and I will have a permanent job .
As I recall this year NASA's budget was cut . Given recent developments the U.S. and Russia will start investing on the development of weapons.
I am familiar with the theory of international relations. Your compatriot John J. Mearsheimer argued that the Cold War did not end because the big countries could not trust each other.So spending a lot of resources on the development of military industry and arms. It was spending resources until eventually one of the countries has not been eliminated.
This situation will in contemporary international relations . Competition between countries for power and control over resources .
In my opinion this situation can be corrected only global government . Uniform for all states. Under capitalism, this is impossible. Only in a socialist system if there is no competition, but there is a common goal can begin to space exploration.
Competition is an incentive to develop , it is an indisputable fact , but the competition is pushing for a tough struggle for resources , mistrust between the countries .
Think global government ever appear, but I have time to grow old and die.
