"Our challenge right now is to refly a rocket within 24 hours. That's when we'll really feel like we got the reusability piece right."
"The Rockets rise was spectacular cutting through the clear skies."
"It's way more impressive, the technology that was developed that lands rocket boosters."
"If the rocket is slightly misaligned, those P and D gains are going to correct for it."
"Composite propellants: Better mix, more power, higher pressures."
"Every system we’ve discussed has either involved making rockets more powerful or cheaper."
"Rocket engines are really all about the plumbing that takes the fuel from the tanks and into the engines."
"SpaceX has figured out how to autonomously land and reuse the first stage of their rockets with a very high degree of accuracy and success."
"Rocket fuel is reaction mass that harnesses the power of Newton's second law."
"The world's most powerful rocket and also the tallest now because it's even surpassed the previous stack."
"This super heavy booster has a diameter roughly two and a half times that of Falcon 9."
"New Glenn is shaping up to be a super impressive rocket."
"I think a full booster burn and the second staging stage ignition would be the moment where I think this flight was successful."
"The concept of making a rocket, giving it its boost by just a general ballistic boost with a gun, is a pretty amazing idea."
"Actually, it top-fired. I just made a rocket-powered pumpkin."
"So in principle, it could be the perfect rocket fuel."
"Looks like a couple of the solid rocket boosters blew away from the side of the shuttle in an explosion."
"Oh man, is that a two-stage rocket? Oh, three. I designed the engine myself."
"It is still the most powerful rocket ever built."
"This is a moon rocket. This is what they use to take people to the Moon."
"Launching hybrid rockets is said to save a whopping 50 percent compared to conventional kerosene-based rockets."
"The rocket lifts up, accelerating under thrust. Motor burnout starts to decelerate, drag and gravity cause it to slow down, and it reaches what we call Apogee."
"Traditionally, rockets were designed to be inherently stable."
"Since the 1960s, most large rockets have been designed to be inherently unstable, with an automated guidance system able to gimbal the engines or actuate fins to keep the vehicle pointed in the direction of travel."
"Ignition and liftoff of the Falcon 9 rocket."
"The success Robert had with his rocket in 1926 was a revolution in innovation."
"I've been trying to propulsively land a model rocket like SpaceX and Blue Origin."
"I'll teach you how to build your own high-powered rocket motors safely using the best techniques."
"We'll be using an ammonium perchlorate composite propellant rocket motor."
"This is how the rocket will steer itself in flight, the central engines can adjust their angle to keep the rocket on course."
"I'm building this using through-the-wall fins, which is one of the most structurally sound ways of doing it."
"I got to play with sparkles and build rockets at the same time, and who doesn't want that?"
"The rocket engine ignites, 3,700 pounds of thrust crushes him back in his seat."
"What an incredible landing, this marks the 117th recovery of a first stage booster."
"It's a history of rocket fuels which is even better."
"Hey folks, my name is Joe Barnard, and I am building a reaction control system for model rockets."
"Reaction control systems are a way to sort of augment the passive stability of high-power rockets."
"A high power rocket is defined as a rocket that uses a motor with more than 160 Newton-seconds of total impulse."
"One rule of thumb for stability in HPR is that the CG must be at least one body diameter in front of the CP."
"Rocketry can be used to demonstrate many different real world aspects of physics and classical mechanics."
"Good luck in all of your rocketry endeavors."
"The first stage of the Falcon 9 is powered by nine Merlin engines producing about 1.7 million pounds of thrust at liftoff."
"He had a passion for life as well as for rocketry and space exploration."
"At the end of the day, you're taking hot stuff and you're accelerating it out of the nozzle."
"We wanted to have the highest operating rocket engine ever by university."
"It's a Saturn V rocket; you can use any rocket of your choice, obviously the concepts will remain the same."
"We're launching our Team American Rocketry Challenge, which is the world's biggest rocket contest."
"This rocket can lay claim to being the progenitor of all modern rockets and space launch vehicles."
"What is your advice for aspiring rocketeers? Pick a section of rocketry that you really like and just go all in."
"As the rocket accelerates, its momentum increases."
"For the last 9 years, I've been building rockets."
"The fundamental principle behind modern rocketry was understood two and a half millennia ago by the Ancient Greeks."
"These early lessons in rocketry will mark the surprising first steps towards manned space flight."
"The only force that's gonna make this rocket accelerate has to do with the combustion inside the rocket."
"It also depends on this other quantity which is how fast it is ejecting stuff from the back of the rocket, that's called our exhaust speed."
"The thrust force is actually proportional to how fast we're ejecting mass from the back of the rocket."
