Amateur Rocket Shows the Curvature of the Planet from 56 Miles Altitude

A team of amateur rocketeers show us what they did on their first test flight without any help from NASA. They built a two-stage amateur rocket which flew to 293,488 ft (55.6 mi/89.5 km). This rocket is called MESOS (short for mesosphere) because it is designed to fly there. The mesosphere is the third layer of Earth’s atmosphere situated between 31 and 53 miles (50-85 km) above the surface. The amazing part about this rocket is it reached this altitude on less than 41,000 N-s of total impulse (full O-class high power rocket motor)! Capable of carrying the equivalent of a 16 oz can of beer/energy drink as a payload, this rocket flew two GoPro Hero 9s cameras with modified rectilinear lenses. Both stages are recovered via parachutes and are reusable. This video covers the development and the launch of this record breaking rocket. I hope you enjoy it!
