The rocket-space industry is always on the lookout for ways to improve efficiency, reduce costs and push the boundaries of what’s possible in space exploration.
A recent study by HRL Laboratories and Boeing, published on the preprint server arXiv, explores a new approach that could lead to significant advancements in rocket propulsion by leveraging quantum computing. The focus is on stabilizing a high-energy-density molecule, cyclic ozone, within fullerene cages—a development that could dramatically enhance rocket fuel efficiency.
Cyclic ozone is an attractive candidate for rocket fuel due to its high energy density. However, its extreme reactivity has historically made it impossible to isolate and utilize effectively. The researchers propose that encapsulating cyclic ozone within fullerene cages, a type of carbon molecule, could stabilize the molecule and make it viable for use as a rocket propellant. This approach is similar to strategies previously considered for hydrogen storage and could potentially increase the specific impulse of rocket fuel—a measure of fuel efficiency—by up to 33%.
A 33% increase in specific impulse could translate to rockets carrying significantly more payload, thereby reducing the cost per launch and enhancing the overall efficiency of space missions. For instance, a SpaceX Falcon Heavy rocket, which currently can carry up to 63,800 kg to low Earth orbit (LEO), could potentially carry an additional 21,000 kg of payload if this technology were implemented. This would have profound implications for both commercial and scientific missions, offering more flexibility and capability at a lower cost.
