Iron Man's dream of Mars is a step closer, and only 18 years old SpaceX has finished
At 3:22 p.m. EDT on Saturday and 3:22 a.m. Beijing time on Sunday, American commercial aviation soared to the sky. This is the first time that a private company has operated a knife to send astronauts into space.
A small step of American pony is a big step of human beings. If the curtain call of Atlantis in 2011 announced the end of the 30-year space age of the United States, now SpaceX has opened a new era for the United States.
Fortunately, the postponement of the weather three days ago and the explosion of the prototype one day ago did not affect this remarkable mission.
What is a manned dragon spaceship?
The manned dragon spaceship is an upgraded version of SpaceX's Dragon spaceship, an unmanned spacecraft that has been delivering supplies to NASA since 2012.
But Musk's SpaceX, is n' t just about shipping,
The manned dragon spacecraft was launched from the Falcon 9 rocket, which was also made by musk. What's more, both of these vehicles can be reused.
Moreover, unlike the Dragon spaceship carrying out cargo missions, the manned dragon spaceship has added an emergency stop system to separate the spaceship from the rocket in case of an emergency during launch.
A mission by two famous NASA astronauts, Bo
Hurley, 53, a retired colonel from the U.S. Marine Corps, joined the NASA crew in 2000 and has been in space for 27 days.
After the launch, it will take about 12 minutes to reach the initial orbit. At the same time, the Falcon 9 rocket can return to earth for future use.
It will take about 19 hours for the manned dragon to reach the international space station, which will gradually raise its orbit to a height of 400 kilometers from the earth.

If all goes well, musk should keep his promise and dance live to celebrate! As he promised at the press conference.
The whole mission cycle may last at least one month, or even up to four months. Eventually, the spacecraft will land on the Atlantic Ocean off the east coast of Florida.
During the return flight, the manned dragon flying ship will launch four parachutes to slow down the descent speed, and finally the spacecraft will land on the Atlantic Ocean on the east coast of Florida. A SpaceX recycling ship will connect bainken and Hurley within one hour after the spacecraft returns to earth.
The U.S. aerospace industry has always been led by NASA. In the new century, the U.S. commercial aerospace industry has a larger share in the whole aerospace industry.
(in July 2011, Atlantis returned to service, marking 30 years of U.S. space shuttle industry pressing the pause key)
The reason is NASA's overburdened space cost. From 1985 to October 1988, the launch price of the space shuttle increased by 85%, that is, the cost of each launch soared to 90 million dollars.
The cost is a total violation of NASA's original design budget for the space shuttle, as well as the original intention of recyclable technology to save launch costs.
NASA chose a more ingenious way to explore space without much investment
For the biggest time in the history of the U.S. space exploration strategy, private companies have become the mainstay of research, development and manufacturing NASA space vehicles
Boeing, arguably NASA's own son, has spent a lot of money being raised by NASA, and it's with another one
The change of the story starts from the big boy's dream of SpaceX. Musk started SpaceX from his own waist. He was not regarded as a good man for a time. In fact, he almost went bankrupt. Fortunately, NASA gave him 1.6 billion yuan and admitted to be a son.
The failure of Boeing, his son, can be said to have given up the good opportunity to musk. Although Boeing received more than 4.9 billion US dollars in funding, SpaceX received much less support, about 3.1 billion US dollars, but made a decision.
(in December 2019, the Boeing Starline spacecraft failed to make its first flight to the International Space Station)
Boeing's attempt to fly in the sky ended in failure for many times. On December 20, 2019, Eastern time, Boeing's CST-100 starliner spacecraft was successfully launched on the cosmos-5 carrier rocket, which was also the first flight of the spacecraft.
Unfortunately, about 50 minutes after the launch, the spacecraft entered the orbit propulsion state by mistake, which should have been the last state when docking with the space station. As a result, it consumed too much fuel to dock with the international space station.
Moreover, SpaceX's offer for a manned dragon spacecraft is $55 million per seat, while Boeing's offer is as high as $90 million per person, more than 60% more expensive than SpaceX's.
You can't do anything. You're the first to spend money and ask for price. Boeing won't take the lead in this matter.
Gan's son took advantage of the victory and pursued the attack. His technical strength soared all the way, even closer to the constant aircraft operation panel of ten thousand years. The simple touch boards on Longfei ship finally kept up with the times.

What does it mean for the United States?
The Kennedy Space Center on the east coast of Florida is now the exclusive show for SpaceX.
In recent years, Russia's ticket prices have risen from more than 20 million US dollars to more than 80 million US dollars.
America can no longer sit.
But spending on space is a headache for U.S. President Donald Trump late last yea
One is to cut funding, the other is to assign tasks. After trump took office, he vowed to let the United States return to the moon in 2024, and then NASA proposed to go there in 2028. It can be said that American aerospace is launched in the cost game.
At present, for trump and NASA, this manned space flight is of great importance. It is the first time that human beings have been launched into orbit from the territory of the United States since the retirement of the United States space shuttle.
This is also a critical moment for the success of trump administration. If all goes well, it will once again establish the leading position of the United States in the field of aerospace, especially in the field of commercial aerospace.
Of course, this is undoubtedly an election year, Trump's great campaign ad.
