During the Cold War, US eyes splashed into Soviet Soviet rockets and satellites. But in recent years, Chinese space programs have been worried about most US strategies.
China, whose space effort is led by the people's liberation army, is currently launching rockets more than any other country, 39 years ago, compared to 31 in the United States, 20 in Russia and 20 in Europe.
On Thursday, the spacecraft on the dark side of the Earth landed, first of all, in any country and in the next decade it planned to build an orbit space space. Over the next decade, I hope that the Chinese "taikonauta" in the moon will make the first moonwalk made in 1972.
China now spends more than civil and military space programs in Russia and Japan. Even if it is opaque, the 2017 budget was $ 8.4 million, according to the Organization for Economic Cooperation and Development.
The United States is less than $ 48 million that spend military and civil space programs, says Smithson analyst Phil Smith, advisor to Bryce Space and Technology. But the Russian civil space budget is more than double $ 3 billion.
After several decades, the methodological stages of space development by the Chinese authorities have repeatedly been repeated: a first satellite in 1970, the first space in space in 2003, the first ship of a nuclear space in an orbiting module in 2012, and the BeiDou satellite navigation system Activation, Chinese GPS response.
"If they continue along this path, Russian eclipses will quickly be made in terms of their space technology abilities," said Todd Harrison, a military space expert in Washington, at the Center for Strategy and International Studies.
Today, China is not threatening the commercial satellite market, remains the leading company based in the United States SpaceX and Europe Arianespace and US space.
China does not advance in space exploration for the decline of the US.
NASA congratulated China on its Chang & # 39; e-4 moon landing, but a 2011 US law is directed by Beijing's space cooperation office, but the Congress may lift this downturn.
The real story is in two areas: short-term, military use of space; and in the long run, exploiting resources in space.
On mineral or water Moon or asteroid mining, especially rockets to produce fuel, is still a long way off, but they are starting to work.
Unlike the cold war, the new conquest of space is spreading in a legal vacuum.
In the 1960s and 70s, Washington and Moscow negotiated various pacts in space, especially in order to guarantee scientific cooperation and to prohibit the destruction of weapons in space.
"These pacts are not so inaccurate as they say that the legal result is something like mining space," said Frans von der Dunk, a law professor at the University of Nebraska-Lincoln.
War in space
Additionally, new military technologies have overcome anti-satellite satellites, cyberattacks, electronic harassment and satelite satellite missiles, which were tested in China in 2007.
War laws govern conflicts in the Land, but there is no equivalent space. There are many unanswered questions.
When the satellite joins the space, is it an "attack"? What response would be proportional? Civil satellites should be protected from repression, but about civilian and military satellites? How does a nation cite a cyberattack that challenges it?
"It is very difficult to distinguish between weapons and weapons that are not weapons," said Jack Beard, a professor of the Nebraska space law program.
"It is unfortunately difficult to spread the armed conflict of the Earth in space," he added. "China is making preparations for future events and … they're experimenting with our communications, satellite, and drone-transmitted systems."
Harrison says: "The United States does not follow the threat to our space systems," and has left the US weak.
In the meantime, the US dialogue with Beijing is almost non-interchangeable with Washington in Moscow during the Cold War.
"If there is a crisis in space in China, it is not clear to our military who knows who," said Harrison.
But other observers take a skeptical approach, portraying China as an aggressive opponent of the United States.
Brian Weeden, a Washington-based Secure World Foundation, said China's anti-threatening proposals make money at tight congresses to raise money for NASA.
"I think they want to motivate the US and do things in space," he said.
"China will see the competition to go to China, to unlock political will and money to finance projects they want."
