Chapter 249 Yenisei

Facts have proved that Douyin is indeed a software that has made the mobile Internet scale expand rapidly and flourish. It is expanding like a virus.

Although the price of Jingwei Satellite Network is generally much more expensive than broadband, 270,000 sets were sold within 24 hours, of which about 65% were the cheapest 50Mbps network.

At the same time, Xinyuan's official website also supports foreign users to order.

However, the price for foreign users is much more expensive. The 100M network receiver that costs 1699 US dollars per year in China costs 899 US dollars per year in foreign countries, which is almost three times more.

In addition to the fact that satellites are less expensive, if it is Aramco, users have to pay additional taxes due to tariff policies. In this case... Normally, they may pay two or three hundred US dollars. If Aramco launches punitive tariffs, they may even pay 2,000 US dollars.

However, the first Aramco user, and possibly the first foreign user, should have set up the antenna.

On the morning of the 23rd, Aramco time, Lao Ma got off the plane with the Supreme Commemorative Edition Jingwei Satellite Network (5000Mbps) antenna.

This is a purely customized antenna, which is not sold outside. The downlink speed is 5Gbps and the uplink speed is 2Gbps, which is enough for ten years.

The antenna is 27 inches in size, with a huge XAP logo on the front. Lin Ju promised that it would be free for life.

Lao Ma downloaded the APP on one of his mobile phones, and then connected to the antenna LAN first, and started the search mode of the antenna placed on the open space.

The huge flat antenna began to rotate 360 ​​degrees, stopped in one direction after a full circle, and then adjusted the elevation angle. The mobile phone prompted that the wifi had an Internet connection.

Opening TikTok, the first video was loaded smoothly, and the network speed number flashed in the status bar was 9MB/S.

He pushed it to download the APP from Google, and the progress bar was stuck for only one second, and the APP of more than 60MB was downloaded.

Obviously, the bottleneck is not the network speed at all.

Musk looked up at the sky along the elevation angle of the antenna. He knew that there was one or several satellites flying at dozens of times the speed of sound.

The Jingwei satellite network has been put into practical use, and Starlink can no longer be delayed.

…

The contact time with Lao Ma was not long, only a few hours, but he did win Lin Ju's respect.

Ma Yilong was not arrogant, and his behavior style was very pragmatic. Lin Ju treated him completely in the relaxed style of Xinyuan Company, and the former was very happy.

Because Lao Ma had seen a lot of serious occasions, especially talking about Tesla's super factory in Shanghai, the pressure was very high.

Lao Ma said that being with Xinyuan's people felt like returning to specaX, and he was extremely relaxed.

Neither of them talked about things too deeply. Lao Ma took a lot of photos and group photos of rockets and Progress space shuttles, and selected some to post on Twitter. Lin Ju directly followed and liked each other.

Lao Ma's trip to China did not dilute the competitive atmosphere on both sides of the Pacific.

On the contrary, on September 21, NACA conducted an SLS ground static ignition experiment.

Two five-segment SRB boosters have arrived at the Kennedy Space Center, and the launch pad renovation work is nearing completion, preparing for the first flight of SLS.

The service module of the Orion spacecraft shipped from Europe was also delivered to the Lockheed Martin factory and will be assembled here soon.

Northrop Grumman also announced that the manufacturing progress of the HALO living module of the lunar orbital gateway space station undertaken by it has exceeded half, and the manufacturing will be completed in January, and it will be launched by the heavy Falcon rocket in February 2017 as scheduled.

The debate in Europe over the Veneto 1 rocket continues. The 11 representatives of the European Space Agency argue from morning to night every day, and the opinions of all parties are different.

However, under the promotion of Italy and France, the desire of the European Space Agency to independently carry out space programs is indeed increasing, especially with the potential guarantee of Veneto 1.

The country is planning to revive the Hermes space shuttle during the Cold War, using it as a round-trip tool for low-Earth orbit and completing combined lunar landings.

The Hermes space shuttle is a symbol of the country's pursuit of an independent space system during the Cold War. Later, it was cancelled due to the sudden reduction of pressure from the collapse of the alliance, and now it has been put on the agenda again.

Now China, Ame, and Russia are all engaged in space shuttles. Can Europe not keep up? Absolutely not.

On the contrary, Daiying is still playing badly as usual, with a very Buddhist attitude, anyway, they will follow whoever is stronger.

But overall, Daiying still supports ESA, because the old Russians are showing signs of collapse.

Now it is 2016, and Russia has already shown signs of economic resurgence. In addition to cooperating with China, its own moon rocket Yenisei Don has really started preliminary demonstration.

Six boosters, six RD171MV engines, one RD180 core stage, total thrust of 5,400 tons, and maximum LEO capacity of 150 tons.

This is also a moon rocket, but Russia lacks confidence and has set a vague "test flight around 2020".

Although the carrying capacity is on par with giant rockets such as SLS, Long March 10, and Xinyuan 2A, it is interesting that the core stage and booster diameter of the Yenisei super-heavy launch vehicle are only 4.1 meters, which is the smallest diameter giant rocket.

The reason is very simple: in order to take care of the backward railway transportation system, Russia's commonly used space launch site is still the Baikonur Launch Center in Kazakhstan, and it can only be transported there by rail.

Although the N1 rocket with a maximum diameter of 17 meters was launched in Baikonur in the last century, it is difficult for Russia to achieve such a transportation capacity now, and there is a fatal flaw in the transportation of large-diameter rockets by rail:

The rocket must be transported in pieces and assembled at the launch site, which greatly increases the probability of problems with the complex internal structure of the giant rocket. The conditions at the launch site are far from as good as those in the production plant.

The frequent problems of the N1 rocket may be due to this aspect. It is assembled at the launch site and then erected as a whole. Compared with vertical assembly, this process is not only troublesome, but also has hidden dangers during the erection process.

In order to reduce the workload and the risk of launch failure, the Russian Space Agency chose a 4.1-meter diameter rocket body, which is the maximum overall transportation diameter allowed by their railway. At that time, the assembly is just the splicing of the booster and the core stage.

Also prepared for the moon landing plan is Russia's new generation of "Eagle" manned spacecraft, which is similar in weight and maximum number of passengers to the Orion spacecraft and the new generation of manned spacecraft, both of which are in the 20-ton level.

At present, Russia has invested 2 billion rubles in the entire rocket and spacecraft project, which is... 28 million US dollars or 190 million RMB.

This figure is the lowest among all countries. Any sub-project of the European Space Agency is much higher than this figure. No wonder the Russian Space Agency was vague and refused to give a specific figure when announcing its lunar exploration date.

With this amount of money, let alone building a rocket, it can't even build two RD171 engines.

On the contrary, India has revised the Gaganyan plan and plans to send two Indian astronauts to space in 2017, build a space station in 2019, and land on the moon in 2020.

The budget of the Gaganyan plan this year is 1.7 billion US dollars, which is 120 billion rubles. Russia is now trying to find a way to steal this money from India.
