Elementary concepts from general physics and thermodynamics have been used to analyze rocket propulsion. Making some reasonable assumptions, an expression for the exit velocity of the gases is found. From that expression one can conclude what are the desired properties for a rocket fuel....
Satellite imagery shows a roughly 40-mile long Russian convoy composed of tanks and armored vehicles. Russian state media warned Tuesday of imminent attacks that will allegedly target the Security Service of Ukraine (SBU) and 72nd Main Centre for Psychological Special Operations...
The upshot of building a bigger rocket is pretty straightforward: heavier payloads and greater range. When it's done, Starship might be able to wrestle up to 250 tons into low-Earth orbit in an expendable configuration or 150 tons with Super Heavy recovery. SpaceX is also working on orbital...

It's not only metals such as iron that might be worth mining from asteroids, Metzger said. Asteroids composed mainly of clay contain a lot of water, which could potentially be used to make rocket fuel on off-world settlements. To become profitable, companies also might go straight to trying...
The rocket is made of stainless steel, a material Musk is particularly fond of due to its relatively low price. Unlike NASA's SLS, which flies on super-chilledliquid hydrogen and oxygen, this beast is fueled with 10 million pounds of liquid methane and oxygen. The new fuel can be stored...
This rotational force is also used to simulate the acceleration of a space launch for astronaut training. When a rocket is first launched, it is so laden with fuel and oxidizer that it can barely move. However, as it ascends, it burns fuel at a tremendous rate, continuously losing mass.Ne...
Almost all the medium in interstellar space — about 99% — is composed of gas, with just 1% being in the form of dust and ice particles. Even though the dust component is minor, it can have a dramatic effect that astronomers call "reddening", or at its most severe, "dust extinction"...
ADI’s portfolio of reliable, rad-tolerant and long life-cycle solutions is helping Aerojet Rocketdyne engineer the most powerful rocket ever developed for NASA – making the first manned mission to Mars possible. See how Aerojet Rocketdyne is putting innovation in orbit ...
What is Ether? Ether is the fuel for the Ethereum blockchain. Although the term Ethereum is often used to describe the cryptocurrency of the Ethereum network, ether is the actual currency used. Ethereumtypically refers to the blockchain, protocol, or network. ...
