While the astronauts are collecting samples of the moon (rocks) one of the astronauts suddenly gets excited as he spots objects flying over them. He’s is really amazed and asks his colleague what these were. Than it becomes hilarious. The other astronaut does not know how to respond so after a short silence he tells him that it was a spark / blast from the high gain antenna. Than hear the amazement of the other astronaut! Spark ??? See the video and than tell me what kind of spark this is.
