Since the mid-1960s, scientists in the image processing lab at NASA's Jet Propulsion Laboratory (JPL) have been working to improve video imaging software, so that astronomers can turn space probe data into increasingly vivid, high-resolution images of distant planets and other celestial objects....
After the moon landing, NASA focused on doing research around the solar system, sending an assortment of manned flights to the moon to collect material for study, and unmanned drones to other planets to collect data. These flights have collected large amounts of data which are constantly being...
