Quizplus · Accepted Answer

Venus has a thick atmosphere that prevents traditional visual observation, so orbiting radar has been used to map the surface. This was accomplished by using a radar instrument that emitted signals which bounced off the planet's surface and returned to the spacecraft. By analyzing these signals, scientists were able to create detailed maps of Venus's surface features.
