"Sun Slingshot Could Propel Fastest Spacecraft Ever"
NASA is exploring a new propulsion method involving a heat shield and solar thermal propulsion system to enable spacecraft to perform an Oberth maneuver around the sun, potentially making them the fastest ever. The project, led by Jason Benkoski, has developed a material capable of withstanding high temperatures and identified methane as the most practical fuel. However, further research is needed, and the project has not yet advanced to Phase II.
