# New Rocket Propulsion System Brings us Closer to Mars By Javier Correas | Published 2007-02-27 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/the-stars-will-be-much-closer References: [blogs.zdnet](http://blogs.zdnet.com/emergingtech/) [Georgia Tech](https://www.trendhunter.com/trends/innovative-vaccine-delivery) researchers have created a new engine for rockets that will help them go faster, reducing fuel spend by 40%. How? Well, in few words, this new system works as a "five-gear engine". The new system lets the rocket save fuel by using solar energy once the rocket is in outer space, using first gear only when acceleration is needed. The project has been funded by the US Air Force with the first uses obviously in military, but let's hope it soon turns into some civil use! ## Trend Insights (Trend Hunter) - Score: 1.7/10 - Popularity: 13% | Activity: 31% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Science](https://www.trendhunter.com/science) ## Key Themes ### Key Themes Behind This Trend - **Rocket Propulsion System:** New rocket propulsion system that can reduce fuel spend by 40% provides opportunities for reduced space missions costs. - **Solar-powered Propulsion:** Increasing use of solar power in propulsion systems presents opportunities for more efficient space missions and reduced environmental pollution. - **Multi-gear Engine:** Innovations in multi-gear engine technology for rockets could provide opportunities for further advancements in space exploration. ### Where This Applies - **Aerospace:** The aerospace industry could benefit from the development of new rocket propulsion systems through increased efficiency and lower costs of space exploration. - **Military:** The military industry could benefit from the new rocket propulsion system developed by Georgia Tech to reduce fuel costs of space missions. - **Renewable Energy:** Renewable energy industry could benefit from the increasing use of solar power in rocket propulsion systems, providing opportunities for technological development and reduced environmental pollution. ## Related on Trend Hunter - [3D-Printed Orbital Rockets](https://www.trendhunter.com/trends/phoenix-engine.md) - [Eco-Friendly Nano Satellites](https://www.trendhunter.com/trends/orbex-prime.md) - [Progressive Air-Breathing Satellites](https://www.trendhunter.com/trends/sabresat.md) - [Rotating-Detonation Hypersonic Engines](https://www.trendhunter.com/trends/GE-Aerospace.md) - [Vortex Rocket Engine Technology](https://www.trendhunter.com/trends/rocket-engine-technology.md) - [Hypersonic Launch Vehicles](https://www.trendhunter.com/trends/launch-vehicle.md) - [Post-Colonization Mars Vehicles](https://www.trendhunter.com/trends/spacex-fusion-concept.md) - [Enigmatically Efficient Engines](https://www.trendhunter.com/trends/efficient-engines.md) - [Regenerative Fuel Spatial Rovers](https://www.trendhunter.com/trends/lunar-cruiser.md)
