What are the meteorological conditions for manned space launch?

Weather has an important influence on transshipment and launch.

The most important weather factor during launch is the high-altitude wind 8- 15 from the ground. Liu said that this is the place with the highest wind speed in the atmosphere. Excessive wind speed will affect the attitude of the rocket. At the same time, if the wind shear is too large, such as the upper and lower wind speeds are different, or the wind direction is different, the rocket may be deformed.

Other factors affecting emissions include cloud cover, visibility, precipitation, surface atmospheric electric field intensity, etc. The best meteorological conditions for manned space launch mainly include: total cloud cover 0-30%, no precipitation; The ground wind speed is less than 8m/s; The horizontal visibility is greater than 20km; From 8 hours before launch to 1 hour after launch, there is no lightning activity within 30 -40 kilometers of the site; The maximum wind speed is less than 70 m/s at the height of 3 km- 18 km where the ship and arrow are launched.

Expanding the scope of human activities is an important means to further develop and utilize space resources on a large scale, which is of great strategic significance to the political, economic and scientific and technological development of the country. Former Soviet cosmonaut Gagarin went into space for the first time on 196 1, and the American Apollo spacecraft successfully landed on the moon on 1969. These two sensational feats have excavated and attracted hundreds of thousands of elite talents.

Experts from the National Aeronautics and Space Administration of the United States have calculated that for every 1 dollar invested in manned space flight, the United States will get a profit of $9, and more than 30,000 kinds of civilian products will benefit from the technology developed by the space shuttle, not to mention the scientific achievements brought by the space shuttle 100 flights. The improvement of manned space technology has also contributed to "space tourism".

In 20001and 2002, American Tito and South African shuttleworth paid $20 million to travel to the International Space Station for about a week. The third batch of two tourists went to the International Space Station in early 2005, with about 10 applicants behind them. Experts predict that space may become a tourist hotspot for ordinary people in the future.
