Do the Rockets have enough to pull off the infamous 3-1 comeback? If momentum is any indicator, impossible is nothing." Tipoff between the Warriors and Rockets is set for 7:30 p.m. CT at Toyota ...

Electric propulsion is being increasingly used on space missions and could ultimately replace thrusters using chemical rockets. Spacecraft powered by electric propulsion could soon be better ...

Ad Astra Rocket Company has spent over two decades developing the Variable Specific Impulse Magnetoplasma Rocket (VASIMR), a highly efficient electric propulsion system.

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. Nuclear ...

Specific impulse measures how efficiently the propellant is used to generate thrust. Nuclear thermal propulsion systems have roughly twice the specific impulse of chemical rockets, which means ...
