90-Day Mars Trips with SpaceX Starship: A New Trajectory

A new study proposes that human missions to Mars using existing SpaceX Starship technology could be shortened to just 90-104 days, significantly reducing the traditional 6-9 month transit time. By optimizing trajectories, the study outlines two new ballistic paths that avoid the need for expensive and complex nuclear propulsion. While challenges remain, including Starship reliability and the construction of Martian refueling infrastructure, this approach offers a promising pathway towards faster and more economical Mars exploration.
