As we reflect back upon the tragic loss of Challenger and her brave crew of heroes who were aboard that fateful day, I am reminded that they truly represented the best of us, as they climbed aloft on a plume of propellant gasses, reaching for the stars, to inspire us who were Earthbound.

Rocket scientists agree that we have about reached the limit of our ability to travel in space using chemical rockets. To achieve anything near the speed of light we will need a new energy source and a new propellant. Nuclear fission is not an option.

Science and technology are a propellant for building a thriving country, and the happiness of the people and the future of the country hinge on their development.

Rockets often spiral out of control if you put too much propellant in them.

American Businessman

Used mostly in scientific or industrial contexts, like aerospace, automotive industries.

Technical Context

Refers to a chemical or material that causes a physical push or thrust.

Physical Action

Though used for movement, it's not for human or animal nutrition unlike 'fuel' sometimes.

Not for Humans

Used metaphorically to describe a driving force behind non-physical actions.

Metaphorical Use

When describing ambition or desire, it implies a strong motivational force.

Emotional Motive

Often positive, signaling initiative and a catalyst for change or progress.

Positive Connotation

 The boys and the rockets get bigger. They use motors used on cruise-missile boosters. They rumble the belly and leave even photographers in awe, watching the spectacle. These rockets use experimental motors like nitrous oxide. They use solid propellant most frequently. It's a strange kind of love. RocketMavericks.com with my photos, if you want to learn about this,

Steve Jurvetson: The joy...

 It's an integrated launch escape system. It's basically a pusher, so the propellant system and the thrusters are integrated into the capsule, and so if it detects a rocket problem, it pushes the capsule away. Capsule safety systems in the past have been like tractor pullers, and the reason we didn't want to do that

SpaceX's plan to fly you...

 It's much like on a jet. So the cost of the propellant is about .3 percent of the cost of the rocket. So it's possible to achieve, let's say, roughly 100-fold improvement in the cost of spaceflight if you can effectively reuse the rocket. That's why it's so important. Every mode of transport that we use,

The mind behind Tesla,...

 atmospheric pressure which ends up liquefying some of the propellant meaning it actually dissolves in the soapy mixture below when you press this button the propellant gas at the top expands pushing the liquid down which in turn pushes it up through the straw out the nozzle and into the world now here

 So it's a lot of stationary battery packs. And then you need electric transport. So electric cars, electric planes, boats. And then ultimately, it’s not really possible to make electric rockets, but you can make the propellant used in rockets

Elon Musk: A future...

 MOXIE is helpful for two One is, you got to breathe. But there’s actually a second reason that requires way more oxygen than breathing. And that's rocket propellant. Rockets burn a lot of propellant, so we have to make a lot of oxygen.

Eric Hinterman: How...

 Satellites even play a role in the operation of our financial and energy markets. But these satellites that we rely on day in and day out have a finite life. They might run out of propellant, they could malfunction,

Let's clean up the space...

 first of all -- hoo -- hairstyles. Second of all, objectively terrible quantities of hairspray, and third, CFCs, chlorofluorocarbons, man-made chemicals that were used as propellant in aerosol spray cans.

Can we solve global...

 People used them to propel great fluffy mounds of shaving cream. And to protect your hair from wind and rain. It was also the propellant that made fire extinguishers and spray paint cans so much fun.

Coming of Age in the...

 Well, Starship will conveniently refill its propellant tanks in space with methane and oxygen. So the way that this works is you launch your first Starship, right?
