The defining feature of these missions is the vehicle that will be doing the atmospheric exploring: a helium-filled, solar-powered airship. The robotic version would be 31 meters long (about half the size of the Goodyear blimp), while the crewed version would be nearly 130 meters long, or twice the size of a Boeing 747. The top of the airship would be covered with more than 1,000 square meters of solar panels, with a gondola slung underneath for instruments and, in the crewed version, a small habitat and the ascent vehicle that the astronauts would use to return to Venus's orbit, and home."
Other times, the culprit is the perception of the sound itself: some letters and letter combinations sound remarkably alike, and we need further cues, whether visual or contextual, to help us out. In a phenomenon known as the McGurk effect, people can be made to hear one consonant when a similar one is being spoken. "There's a bathroom on the right" standing in for "there's a bad moon on the rise" is a succession of such similarities adding up to two equally coherent alternatives.
Finally along with knowledge, we're governed by familiarity: we are more likely to select a word or phrase that we're familiar with, a phenomenon known as Zipf's law. One of the reasons that "Excuse me while I kiss this guy" substituted for Jimi Hendrix's "Excuse me while I kiss the sky" remains one of the most widely reported mondegreens of all time can be explained in part by frequency. It's much more common to hear of people kissing guys than skies.
