Limitless Space Institute for Interstellar Travel by 2100

Limitless Space Institute is sponsoring student programs and giving away about $2 million every two years in grants for work towards enabling interstellar travel. They gave out nine grants. Limitless Space Institute is working with the Breakthrough Institute. Limitless Space Institute is led by Sonny White. Sonny White and his team is also working on …

Extreme Solar Sails Will Slingshot Around the Sun to 0.1% of Lightspeed

Solar sails made out of extreme metamaterials, nanostructured and with some ceramics will be able to withstand over 1000 degrees celsius. They will reach slingshot within 2-5 solar radii of the sun, which is 2 to 4 times closer than the Parker solar probe. The solar sails should cost about $10 million per launch and …

Diffractive Lightsails

Unlike a reflective solar sail, a sun-facing diffractive solar sail uses a component of force perpendicular to the sun line. This allows navigation without sacrificing the amount of solar power on the sail. The angular deviation of light from a diffractive film may be engineered to provide electronic, rather than mechanical, navigation protocols, e.g. by …

Extreme Metamaterial Solar Sails for Over 0.1% of Light Speed

Understanding the beginnings of the Universe and life itself is NASA’s long term vision and one of humanities’ grand challenges. Missions to the edge of our solar system and to space between stars in our galaxy – the interstellar medium – are of a great promise to shed light on these questions. However, today’s deep …

More than doubling the performance of solar sails with diffractive metafilm sails

A Rochester Institute of Technology researcher could more than double the performance of solar sails by creating diffractive metafilm sails. This will initially be used to raise cubesats to higher orbits. The new materials could be used to steer reflected or transmitted photons for near-Earth, interplanetary and interstellar space travel. Diffractive metafilm sails could solve …

Solar Sails and Electric sails

With composite booms, the NASA principal investigator believes we could make 1000 to 4000 square meter solar sails today with a funded project. Then with the learnings from that mission we could rapidly advance to 10,000 square meter solar sails. Les Johnson believes that he can see the development path to kilometer sails with a …
