What Does NASA Stand For?

During its 14 year expedition to orbit Venus this machine uaed a radar to map the surface of a resolution of 75 kilometers or 47 miles. It found the planet to be generally alot smoother than Earth. It had a mountain that is taller than Mount Everest and a chasm deeper than the Grand Canyon. The probe also found Venus to be more sperical than Eath, it also has a much slower rotation route being one Venus day equals 243 Earth days! It is confirmed that Venus has has little, if any, magnetic fields and found the clouds to consist mainly of sulfuric acid. Measurements of this chemical's decline in the atmosphere during the course of the mission suggested that the spacecraft had arrived shortlt after a large volcanic eruption, which may also account for the prostdigios lightning it saw.
