The earliest rockets were invented about 800 years ago, and they were used for fireworks.
The rocket needs only 8 minutes to accelerate to a speed of 24,000 kilometers per hour.
Rocket engines are one of the pinnacles of technological progress. Materials working to the limit, hundreds of atmospheres, thousands of degrees, and hundreds of tons of thrust - this is amazing. But there are many different engines, which one is the best for "cleaning" LEO?
