Light reflecting from any surface transfers momentum to that object.\n\n###\n\n\n\n\n###\n\n\n\n\n\nThough the force generated by shining light on something appears minimal, the microgravity conditions of space allow even modest cumulative effects to become meaningful.\n\nSolar sail experiments have previously demonstrated that sunlight alone can generate sufficient thrust to propel specially designed spacecraft.\n\nEarlier this month, European Space Agency scientists proposed using lasers to guide solar sails and adjust satellite positioning through graphene aerogels, an exceptionally lightweight porous material.\n\nThe Texas A&M team maintains their concept can expand well beyond microscopic demonstrations.\n\n###\n\n\n\n\n###\n\n\n\n\n###\n\n\n\n\nSince the propulsive force depends on the intensity of the light source rather than the object's dimensions, sufficiently powerful lasers could theoretically push much larger structures.\n\nTheir paper suggests applications ranging from tiny microrobots to full-scale interstellar light sails for deep space exploration.\n\nNevertheless, significant questions about practical feasibility persist. The researchers conducted their experiments in a fluid environment to counteract gravitational effects.\n\nThey now seek external funding to evaluate the technology under actual microgravity conditions in space.\n\n###\n\n\n\n\n\n\n\n\n\n\n**Our Standards: The GB News Editorial Charter**",
