Lasers could one day steer solar sails and adjust a satellite’s position in outer space, thanks to graphene. An experiment on a gravity rollercoaster ride showed how this innovative material has the potential to revolutionize propulsion beyond Earth.
An international research team boarded ESA’s 86th parabolic flight campaign in May 2025 with ultralight graphene aerogels, then hit them with light during zero gravity phases to observe their reaction under space-like conditions.
The effect of the laser during the microgravity phases was startling: The graphene samples shot forward instantly.
Your post on such an teresting subject has left me speechless. I regularlyly check out your blogs and stay current by reading the material that you offer; nevertheless, the blog that you have posted today is the one that I appreciate the most.
