This new propulsion system could rewrite the rules of spaceflight—not to mention completely defy conventional physics.

This is why rockets are launched vertically, to generate as much downward thrust as possible. However, those thrusters are extremely resource-hungry, gobbling up fuel and power in record time.

A bold new propulsion system, proposed by engineer Jim Woodward, suggests that it might be possible to escape Earth’s gravity ...

The Space Launch System (SLS) core stage and rocket boosters have now been stood up and mated in preparation for NASA's ...

This high thrust allows the rocket to accelerate faster. These systems also have a high specific impulse. Specific impulse measures how efficiently the propellant is used to generate thrust.

The slow race of getting NASA's Space Launch System rocket pieced together for next year's Artemis II moon mission jumped a ...

A video (top) shows the Ariane 6, which is similar to SpaceX’s workhorse Falcon 9 rocket in terms of launch thrust, leaving the launchpad on Thursday. The footage also captures other crucial ...

India's space ambitions soared as Isro successfully conducted the first major hot test of its 200T thrust semi-cryogenic ...
