As it applies to rockets, the force produced by the rocket’s engine will be directly proportional to the mass of both the fuel and particles that are produced by the rocket propellant burn multiplied by the acceleration of the combustion products out of the engine. The law’s application in...
You can scale your batch sizes as you deem necessary. You can get at least 14 rocket nozzles made from a 2oz batch. So a 4 oz batch will give you plenty of clay to make at least 25 rocket motors (a whole bag of rocket motor tubes!) The heating times get longer with a larger ba...
let you talk with ground-based flight controllers (communications and tracking) find its way around (navigation) make electrical power coordinate and handle information (computers) enable you to do useful work (launch/retrieve satellites; construction - such as building the International Space Station;...
Skylab was never meant to be a permanent home in space, but rather a workshop where the United States could test the effects of long-duration space flights (that is, greater than the two weeks required to go to the moon) on the human body. When the flight of the third crew was finis...
Retired NASA astronaut Leland Melvin, an NFL Hall of Fame inductee, explains that it takes longer for some astronauts to get chosen by NASA than others. He notes that while he applied to the astronaut program only once, some people apply many times before getting selected....
Bring me a Snapdragon X laptop with a 360-degree screen that also lets me fold the device into a tent shape that eases economy-class movie viewing, and I’ll be ready to buy. Except if this machine comes from HP, in which case I’ll have to think about that for a little longer. ...
Three things make a jet engine more powerful than a car's piston engine:A basic principle of physics called the law of conservation of energy tells us that if a jet engine needs to make more power each second, it has to burn more fuel each second. A jet engine is meticulously designed...
So to start off, let’s make one thing clear. Humans will not be abandoning traditional rockets any time too soon. There just simply is no other form of propulsion feasible with our current technology. As much as I want to believe in anti-gravity warp drive magnetic super thrusters that ...
“The difference is now we’re closer to actually developing these technologies into operational systems – weapons, space vehicles and manned aircraft,” Cresci says. “In the testing world that means we are doing longer duration tests, at higher speeds and testing a variety of techno...
“Obviously it affected us emotionally,” said Garrett Reisman, a spacecraft engineer from California who in 2003 was member of the NASA astronaut corps waiting to make his first foray into space. “I remember being called into the office, volunteering to work with families,” Reisman added. ...
