Jack Alymer: FLYING THROUGH SPACE WITH THE POWER OF THE SUN-
THE STUFF OF SCIENCE FICTION IS HAPPENING FOR REAL
NASA JUST SUCCESSFULLY DEPLOYED ITS ADVANCED COMPOSITE SOLAR SAIL SYSTEM-
USING IT TO CARRY A SPACECRAFT IN ORBIT AROUND OUR PLANET USING ONLY PHOTONS FROM THE SUN.
THE SAIL COVERS OVER 850 SQUARE FEET-
AND WORKS MUCH LIKE A SAILBOAT WOULD ON EARTH.
BUT WHEREAS A BOAT IS PROPELLED FORWARD BY HARNESSING THE POWER OF THE WIND-
THE SOLAR SAIL INSTEAD USES THE PRESSURE OF THE SUN’S RAYS TO GENERATE ITS PROPULSION.
PHOTONS BOUNCE OFF THE REFLECTIVE MATERIAL, PUSHING THE SPACECRAFT IN ITS DESIRED DIRECTION BASED ON THE SAIL’S ORIENTATION.
SCIENTISTS HOPE THIS MARKS A BIG LEAP FOR SPACE EXPLORATION-
SPACECRAFT USING A SOLAR SAIL ARE NOT LIMITED IN THE DISTANCES THEY CAN TRAVEL BY FACTORS LIKE AVAILABLE FUEL OR ENGINE CAPACITY.
NASA ENVISIONS A FUTURE WHERE SAILS CAN HELP SUPPORT EARLY-WARNING SATELLITES, SURVEILLANCE, AND SOLAR OBSERVATION MISSIONS.
AND THERE’S A CHANCE YOU COULD CATCH A GLIMPSE OF IT FROM ALL THE WAY DOWN HERE ON EARTH.
BECAUSE OF THE SAIL’S HIGHLY REFLECTIVE MATERIALS, IT CAN BE SPOTTED ON CLEAR NIGHTS AS IT ORBITS AROUND EARTH.
