, the spacecraft of the galaxy far, far away are propelled through space by massive engines glowing bright blue. Current spacecraft may pale in comparison, but the technology that powers these ships is becoming a reality.

Space Wars - Wikipedia

Other countries like China have devoted significant resources toward developing space capabilities. That’s why ensuring that the United States is leading in rocket technology is important to allow U. spacecraft to respond quickly to changes in low-Earth orbit and deeper in space.

Developing different rocket technologies and fuel variety can equip the United States with a plethora of options for maintaining low-orbit spacecraft, traveling to Mars, and harvesting resources from space for transportation back to Earth in an economical time frame. Innovations in rocket propulsion using several different types of designs can allow future spacecraft to reverse course, turn around, change directions mid-flight, and reach their destinations in a matter of months.

Plasma rocket technology will be the key building block for long-distance space travel. The federal government should continue to champion this technology’s development for further utilization of space resources and defense applications.

Plasma-based systems work by heating ions of fuel to create plasma and then directing that plasma using magnetic fields to be dispensed in a particular direction. This creates thrust to propel a craft forward, but plasma-based engines can vary plasma output and direction, creating much more potential for navigating the vacuum of space.

Ad Astra’s Variable Specific Impulse Magnetoplasma Rocket (VASIMR), for example, can vary thrust power and can take either hydrogen, helium, or deuterium as fuel. This variety of fuel types would allow for extreme flexibility in space, as electrolysis would split water into usable oxygen and hydrogen for human consumption and fuel for the plasma rockets.   As hydrogen is also one of the best shields against harmful radiation, its use as fuel for plasma rockets would reduce the likelihood of astronauts or sensitive machinery being damaged by space radiation and any potential radiation given off by the engines themselves.  

Plasma-based rockets have the potential to radically decrease travel times in outer space and in low-Earth orbit.

Most rockets today are designed around chemical use, which caps their exhaust velocity around 5,000 meters per second. While that may seem fast, this causes multi-ton rockets to carry thousands of gallons of fuel to deliver a small payload to a distant planet.

Capping exit velocity also leads to journeys that would take months, even years, to complete one-way. Using plasma-based rocket technology, like the Pulsed Plasma Rocket (PPR) developed by NASA and Hbar Technologies, has the potential to cut humans’ travel time to Mars down to only two months. Current investigations into PPR technology have shown that this type of engine may be capable of generating 20,000 pounds of force (lbsf).

This force generation runs against the need for constant electron bombardment within the engine to produce plasma, meaning a consistent source of electricity is needed.
