A mission to one of Mars’ moons could potentially provide an opportunity for meaningful scientific work while the final Mars entry, descent and landing systems are still being completed. This is an artist’s depiction of an astronaut and rover on Mars’ moon Phobos. Credit: NASA/David Hitt

Although #photons don’t have #mass, they can still impart #momentum. #Solar #sails rely on this fact to #accelerate continuously on their journeys through #space, reflecting photons off of their paper-thin surfaces to push themselves onward. Though they start slow, after a few years, the sails can travel at astonishing speeds. What’s more, they don’t need to carry any #fuel with them (though some may come equipped with lasers to provide photon-powered momentum when the #sail travels too far from the #sun). #outerspace #tech #technology #astronomy #light #physics
Greek physicist and astronomer Dionysis Simopoulos https://en.wikipedia.org/wiki/Dionysis_Simopoulos gave us a nice introductory lecture on astronomy, the universe and recent breakthroughs in the field. Quite interesting stuff!
