Usage

To use the wcag-dictionary component, wrap any text that includes terms for definition in the component. This will create interactive tooltips for enhanced accessibility. 

                        
<wcag-dictionary preload="true" activeText="Active" inActiveText="Inactive">
    <section>
        <p>Explore advancements in propulsion systems for space missions.</p>
    </section>
</wcag-dictionary>

Styling

The wcag-dictionary component is styled for accessibility and readability, with customizable colors and tooltip styles to suit various design systems.

Rocket propulsion systems remain at the heart of advancements in space exploration. Chemical propulsion, primarily through bipropellant and solid rocket engines, continues to be the preferred method for launches due to its high thrust and reliability. Liquid-fueled engines, like the RP-1/LOX or cryogenic LH2/LOX combinations, offer significant ISP for orbit insertion and flexibility in throttle control—ideal for multi-stage and reusable systems.

Once in orbit, electric propulsion, particularly ion and Hall effect thrusters, is leveraged for its high efficiency and low propellant consumption. Thrusters like the Xenon-based ion drive, operating at a fraction of chemical thrust, provide prolonged thrust ideal for station-keeping, orbital transfers, and interplanetary missions. Though acceleration is gradual, these systems' specific impulse outperforms chemical engines, maximizing fuel efficiency over extended missions.

Looking forward, nuclear thermal propulsion (NTP) and nuclear electric propulsion (NEP) offer promising pathways for deep space. NTP, by heating a propellant through nuclear reactions, could drastically reduce transit times to Mars and beyond, while NEP, integrating nuclear reactors with electric thrusters, promises extreme ISP, though it faces challenges in heat management and radiation shielding. These technologies could bridge the gap between current propulsion capabilities and humanity’s aspirations for interplanetary travel.
