SUMMARY: NASA has successfully tested two small aerospike solid rocket engines, demonstrating the capabilities of this new technology. An aerospike engine is like a regular rocket, but flipped inside out. Instead of the traditional bell-shaped nozzle, and aerospike can change the flow of its exhaust throughout its flight, maximizing its performance.
