If the rocket cannot be launched on time, the launch must be postponed, waiting for the next launch window, or even one or more days before launch. Therefore, the ‘zero window’ launch puts higher requirements on the reliability of the rocket.

　　 Take my country’s Chang'e series launches as an example. The launch window of "Chang'e-1" is reserved for 35 minutes, and it can be launched within these 35 minutes.

However, compared with launching in the first minute at the last minute, the satellite fuel will lose 120kg. This is a great loss for the Chang'e-1, which has only 1,200kg of fuel in total, and will directly affect its working hours and life span.

　　 If the launch cannot be carried out normally within 35 minutes due to special reasons, the launch plan can only be cancelled and the launch window will be postponed to the next year.

　　 The launch of "Chang'e-2" in the "zero window" can save 180 kg of fuel, and the on-orbit test time will be greatly extended.

　　 Such a big gap, it is no wonder that Zhang Hanxiu is so nervous. If all the payloads can be launched in the ‘zero window’, then their work will be done.

　　 This is also the reason why they have been running to the weather monitoring laboratory recently, because the rocket launch may be delayed due to technical problems, and almost all other reasons can be linked to the weather.

　　 Although the company has recruited a lot of meteorological experts and purchased and manufactured a lot of weather monitoring equipment, its experience is still incomparable with the national aerospace department, which has extensive rocket launch experience.

　　 That's why the group company invited partners to help the meteorological experts of these companies master the weather monitoring during rocket launch.

　　 Cooperating with the national team is a policy set by Lei Tiantang himself, and it was also endorsed by all members at the company's meeting.

　　 If everyone thought it was a little weird before, then as the company's space planning step by step, everyone in the company began to believe that the boss's spacecraft plan is really possible to succeed!

　　 Huge financial support, more and more top scientists and researchers, and clear development plans make the company feel that in the next 20 years at most, the group company will be able to initially master the manufacturing technology of solar system spacecraft!

　　At that time, what more satellites, space telescopes, and space stations need to be launched. Just load them into the cargo ship of the spacecraft, and then directly use the spacecraft to pull them from the ground into space.

　　 In other words, no matter how advanced the rocket is, it will be eliminated! Even the heavy launch vehicle being developed by Infinite Gravity Group will definitely not be needed by that time!

　　 Because in accordance with the company's heavy-duty launch vehicle development standards, the maximum payload of the low-Earth orbit can reach 200 tons, and the escape orbit can reach 70 tons.

　　 Such a carrying capacity, even if all countries and companies in the world want to achieve this standard, it will take a long time. It can be said that after the completion of research and development, the rocket technology of Infinite Gravity Group will be regarded as the world's top.

　　 Although this kind of carrying capacity seems to be a lot, it can also meet the needs of space station construction and the mission of launching various probes in the solar system, but it is far worse than spacecraft!

　　 Because even according to the lowest standards, the design standards of the company's first-generation spacecraft must exceed this number!

　　Using nuclear fusion reactors as energy sources allows the spacecraft to have inexhaustible energy. The minimum load of the spacecraft can also exceed 1,000 tons, which is still the minimum standard.

　　 The maximum load must at least exceed 3,000 tons, and only such a large load can satisfy the company's future mining business on the moon and Mars.

　　Satisfy the company's initial construction work for space colonization on the moon and Mars. After all, there were too many materials to be transported to these colonies at that time.

　　 If the rocket is used to launch slowly, even Lei Tiantang can't afford such a launch cost. Even if the company's heavy rocket can increase the escape load to 100 tons, it will not help.

　　 If you want to build a long-term survival colony, at least you need to pull tens of thousands of tons of various materials from the earth!

　　 By that time, the group company launches rockets into space every day? Otherwise, when will so many materials be shipped?

　　 Not to mention that it is impossible for the company to build a colony on such a large moon and Mars. Even according to the minimum requirements, it will at least build more than 10 bases.

　　 Places rich in mineral resources, of course, must first enclose the ground, otherwise, do you have to wait for other countries and companies to occupy these places?

　　 If hundreds of thousands of tons of materials want to be launched by rocket, the group company must launch at least 5000 times! What is this concept?

　　 Even if 5 fully loaded rockets are launched every day, it will take nearly 3 years to launch!

　　 These 5,000 rockets alone are a huge expense. Even if the group company designs recyclable rockets~lightnovelpub.net~, at least 200 rockets must be manufactured to meet the launch needs!

　　Because the rocket is made by the company itself, the company can afford to spend the money, but the various supporting projects cost a lot!

　　The deployment of various materials, the salaries of various personnel, etc. are all expenses that need to be paid for a long time. The expenses in this area must be paid at least tens of billions of dollars each year!

　　 And every launch is a challenge. No matter how mature the technology is, various uncertain factors will cause rocket launch errors.

　　 These mistakes will slow down the launch speed, and the lost materials will need to be prepared again. There are also various adverse weather effects, such as typhoons, thunder and lightning, and other weather cannot be launched.

　　 Therefore, it is impossible to launch rockets into space every day. In this way, the speed of colony construction will not be guaranteed, and the company may be dragged down by such construction projects to normal development.

　　 Therefore, rocket launch is a technology that is destined to be eliminated. No one disagrees with the company's cooperation with the country.

　　 The spacecraft can lift the rocket at least 30 times by pulling the cargo once, not to mention the superiority in safety and so on.

　　 With such a wonderful future cargo tool, who would use rockets as treasures? When they are still useful, let them maximize their benefits!

　　 Anyway, people in the company don’t feel that they can’t complete the company’s plan now. Isn’t it just building a spaceship? Roll up your sleeves and work hard, and you will surely succeed in the near future!
