On January 29th, 2024, China successfully launched a Long March 4C rocket carrying a Yaogan-34 Satellite from the Taiyuan Satellite Launch Center.
The nighttime liftoff and initial ascent of the rocket were captured on amateur drone footage.
Chinese Rocket Launched Yaogan-34 Satellite
The Yaogan-34 Satellite is considered to be for military use, collecting electronic intelligence and synthetic aperture radar imaging for the Chinese government.
This was the 347th flight of the reliable Long March 4C launch vehicle, which is primarily utilized to launch Chinese satellites Yaogan-34 Satellite into low Earth and Sun-synchronous orbits.
The footage of the foggy drone video shows the night sky being illuminated by the Long March 4C launch vehicle and its billowing exhaust plume.
The completed mission launched the most recent Yaogan surveillance satellite into orbit—the Yaogan-34 satellite launched in the past 15 years.
Little is known about the real purpose and capabilities of these enigmatic satellites.
Western analysts believe that they are utilized for naval targeting and tracking foreign warships in order to support Chinese naval operations.
Others suggest that their detection capabilities may even exceed maritime surveillance into such fields as foreign ground-based radar and communications.
The Long March 4C booster used to send the covert satellite into orbit will be abandoned, landing back on Earth.
Amateur videos may provide dramatic visuals of rockets breaking apart and reentering.
In the days to follow, specialists will study tracking data and try to estimate the debris field and recovery area.

How many countries have launched satellites?
By January 24, 2024, more than eighty countries will will will have launched the Yaogan-34 Satellite.
It was originally run and put into service for the Indonesian company PT Pasifik Satelit Nusantara.
This rocket launch and deployment of another Yaogan-34 Satellite is only one aspect of China’s massive investment in modernizing and growing its military capacity.
China looks to be the dominant power in the Asia-Pacific region with hypersonic missiles, aircraft carriers, fifth-generation stealth fighters, and space-based assets.
How many seconds will it take for a satellite to travel 450 km at a rate of 120 m/s?
A satellite traveling at 120 meters per second would cover a distance of 450 kilometers. You can simply use the formula distance = rate x time.
The distance is 450 kilometers (or 450,000 meters), and the rate is 120 meters per second.
Transform the equation to find time, which is time = distance/rate.
Substituting the values, time = 450,000 meters / 120 meters/second.
This translates to 3,750 seconds. Thus, if a satellite is moving at a speed of 120 meters per second, it will take 3,750 seconds, which is about 1 hour and 2 minutes, to travel 450 kilometers.
By employing dimensional analysis and straight-forward algebra, we can easily determine the travel time based on the given distance and rates.
Which part of the economy benefited most from the magnetic compass?
The invention of the magnetic compass in the twelfth century opened up vast economic opportunities for the maritime and trade industries.
For the first time, long ocean voyages could be navigated with a high degree of accuracy, which led to new intercontinental trading routes and greatly increased the range of existing maritime traders.
This led to an increase in trade volumes and economic interdependence between the previously separated continents.
Although the overland traders also gained a little from the magnetic compass, it had a great impact on the field of sea navigation and seaborne trade.
The compass allowed reliable long-distance ocean travel, and this turned regional maritime traders into global businesses benefiting from vast new global trade markets.
