The future of deep space exploration may not rely solely on chemical propulsion. Our research focuses on using solar sails to harness the momentum of solar wind — a stream of charged particles from the sun — as a means to propel spacecraft without fuel.

Inspired by how a sailboat catches wind on Earth, a solar sail reflects photons and solar particles, transferring momentum to the spacecraft. Though weak in force, this thrust accumulates over time, offering significant speed gains with no mass consumption.

Core Concepts

• Photon pressure: Light has no mass, but carries momentum.
• Solar sail design: Ultra-thin, reflective materials like Kapton or Mylar are used.
• Trajectory control: Orientation of the sail controls acceleration direction.
• Longevity: Continuous thrust allows interstellar missions that chemical rockets can't sustain.

Experiments and Simulations

We conduct:

• Vacuum chamber tests simulating solar pressure.
• Orbital mechanics simulations using Python and MATLAB.
• Deployable sail prototypes using CubeSat platforms.
• Collaborations with space agencies (ESA, JAXA) on missions like IKAROS and LightSail 2.

Real-World Potential

Solar sails can:

• Extend satellite lifetimes by counteracting orbital decay.
• Enable lightweight probes to reach outer planets.
• Support long-duration missions to Alpha Centauri or beyond.
