When launched, the Hubble Space Telescope carried a mirror with a wrong shape. This led to images that were not sharply focused. Astronauts were sent on a servicing mission to correct the error after three years. The correction was designed by engineers to make the images much sharper than before. Which step did the engineers take next to decide if the correction was successful? A)They used the telescope to look at fainter space objects than before. B)They used the telescope to look at more distant space objects than before. C)They ran special computer software to process the images after the correction. D)They compared images of the same space objects before and after th
