A SPACESHIP which is so fast it could travel 3.6 million miles per day has been successfully tested in Earth’s orbit.
The Lightsail 2 craft is an experiment to prove the practical application of a controlled ‘solar sail’, which has the ability to far outstrip traditional rocket engines. The revolutionary mission was launched on June 25 and developed by ‘The Planetary Society’, based in the US. The voyage became the first ever to demonstrate solar sailing and used energy from the Sun to orbit Earth.
