The U.S. lunar rocket Artemis 1, delayed launch. About this matter, everyone is used to it, after all, it is one of the six ace pigeons in the international space industry, and it is strange that it can be launched on time.
Which six ace pigeons? They are nasa's Weber deep space telescope, the United States Boeing SLS rocket and its lunar landing program, respectively, the United States ULA Vulcan rocket, the United States Blue Origin New Glenn rocket, the United States Boeing manned starship, the Soviet Union/Russian Science experimental module.
The Webb Deep Space Telescope was delayed 18 times, the ULA Vulcan rocket was delayed 3 times and failed 7 times, the New Glenn rocket was delayed 8 times, the Boeing manned starship was delayed 5 times, the Science experimental module was delayed more than a dozen times, and the United States postponed a total of 16 times this lunar landing plan.
The six ace pigeons in the international space industry, the Americans monopolize 5 of them, and under what circumstances, the moon landing is postponed again, it is simply a normal thing, or that if the launch is successful, it is called big news.
As for this failure, the problem has also been found, and it is the pre-cooling purging of the No. 3 machine that is the problem. And the problem had already arisen during rehearsals, but it was not the U.S. government that ordered a forced take-off as originally planned. At this time, some people asked, why are Americans so anxious? Isn't that silly? In fact, they are also forced to be helpless.
The SLS rocket was originally scheduled to take off in 2016, and as of today, the cost has increased from the initial 7 billion to 20 billion. Of course, the 20 billion is not all from the United States itself. To scrape together so much money, the United States approached the United Kingdom, ESA, the United Arab Emirates, Japan, Italy, Canada, Australia, Luxembourg, South Korea, New Zealand, Brazil, Ukraine, Israel, Poland, Mexico, Romania, Bahrain and Singapore. A total of 18 countries and regions asked for money.
So that's why they can't abandon the plan even after more than a dozen consecutive failures: the cost of sinking is too high, and it's all the cost of allies that sink. Americans are long gone by no longer the largest shareholder in the program.
As early as the beginning of August, the cattle had been blown out. But after all, science is not blown out, it will not be transferred according to the ideas of politicians, especially aerospace, there are problems or problems, so it has to be postponed again.
Think of that year, the United States but engaged in the Apollo moon landing program, the mature Saturn V rocket they are not nothing, why can not use the past rocket, but their own time and energy to re-?
There are two reasons, the first of which is that the technical process is outdated. The control center of Saturn 5 at that time was based on a traditional mainframe computer design. Its total memory module capacity is only 16k bytes, but it weighs 32.9 kilograms, and the host frequency is only 2MHz, which is completely incomparable with today's computers.
According to the American conception, this moon landing is not only to claim that humans have landed on the moon, but also to be able to carry out various exploration missions between the earth and the moon. It will also enable astronauts to live and work in deep space, will complete a series of scientific exploration experiments, and plans to build a permanent base on the lunar surface.
NASA said it hopes to send some scientific instruments and payloads to the moon "to motivate students to participate in scientific exploration projects."
Therefore, the computers of the past lunar rockets are no longer enough, and they must be upgraded. Now the computer used in the United States to land on the moon, its theoretical operating speed, is 20,000 times that of that year, and the memory has increased by 128,000 times.
That being the case, why not make direct improvements on the basis of Saturn V? You have to redesign one
The answer is that rebuilding Saturn V costs more than the SLS rocket. The cost here is higher, not just the cost of manufacturing. What's more, thousands of parts of Saturn 5 are no longer produced, and some manufacturers have long since closed. If you want to rediscover the hardware equipment manufacturers of the 1960s, it is better to redesign the rocket.
Are you saying americans lack technology? In fact, there is no shortage. What's missing from the design? Definitely more than lacking. Compared with the power of Saturn 5 in that year, the design of SLS is more reasonable, the technology is more excellent, the fuel use efficiency is higher, the flight speed is faster, the air stay time is longer, and the scientific research ability is stronger. Chinese astronauts have to give a thumbs up and thumbs up when they see it. If nothing else, compared to China's Long March series of rockets, Americans are indeed better at rocket design.
Why china's aerospace industry has been developing more and more smoothly recently. It's not that our technology has completely surpassed the Americans, but that our industrial standards are better than the Americans.
Since the United States learned the shameless means of harvesting the world with dollars, it has completely abandoned its own industry, and now in the United States, everyone is Wall Street, and skilled mechanic dogs are not wanted. In this case, the current situation of the loss of senior technicians in the United States has become inevitable, and a large number of skilled high-level blue-collar workers have wandered the streets as homeless people.
Over time, it has created the current situation of the hollowing out of American industry. Now the United States, let alone space rockets, F-22 fighter production line can not be reopened. Even cars can't be built, because the auto city of Detroit has long been bankrupt, the factories inside are very dilapidated, and the large-scale mechanized agriculture and financial industry are the two core pillars of the current United States.
In contrast, in China, when the mainland produces the Long March series of rockets, it can not only borrow the 111 factory, the 211 factory, but also the large factories such as Chuannan Fireworks Technology Co., Ltd., but also can find suitable parts from all over the country to install the rocket through bidding.
Therefore, China's space program can develop steadily, and all kinds of strange brain holes of space researchers can become a reality.
Finance is good, but if there is no industry, then there is no way to turn money into actual industrial goods. If you don't believe it, you can look at the United States, $20 billion, the U.S. government is really willing to throw money, but what is the use? Without industrial support, how much money is spent, and in the end, you may not get the results you want.
