An appalling accident rate [5] led individuals such as G. Harry Stine and Vernon Estes to make model rocketry a safe and widespread hobby by developing and publishing the National Association of Rocketry Model Rocket Safety Code, and by commercially producing safe, professionally designed and manufactured model rocket motors. Model rocketry by ...
Homemade Astronauts is a television show on Science Channel (Discovery Science USA) and Discovery+ that debuted in 2021. It featured DIY wannabe astronauts, who design and build their own equipment, in an attempt to reach the edge of space.
Brian Walker is a toy inventor from Bend, Oregon [1] who is known for attempting to build his own rocket and as the inventor of several toys, namely the air bazooka.

The rocket is launched using liquid hydrogen and liquid oxygen cryogenic propellants. Rocket propellant is used as reaction mass ejected from a rocket engine to produce thrust . The energy required can either come from the propellants themselves, as with a chemical rocket , or from an external source, as with ion engines .
In 2023, Rocket Lab launched 10 times, but in 2024 the New Zealand-U.S. rocket company turned that dial to 16, making for some really easy math: Rocket Lab grew its launch cadence 60%, and thus ...
A rocket's required mass ratio as a function of effective exhaust velocity ratio. The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the ...
Hendrycks said he was inspired to create “Humanity’s Last Exam” after a conversation with Musk about existing AI tests being too easy. “Elon looked at the M.M.L.U. questions and said ...
