Troopers never enforce it however. A broken white line on a two lane highway means it's OK to pass slow moving cars on the left if the coast is clear in-front of you. Source(s): Alignment, suspension and brake shop. In Europe, it means you may overtake, but with caution. A soild line means to not cross over.
Best Answer: There have been 6 manned Moon missions, between 1969 and 1972. I'm assuming you mean manned trips to the Moon. All of those were conducted by the US, from 1968 through 1972; 9 missions in all. Apollo 8 was the first time man visited the Moon, in December 1968 right at Christmas time. It was famous for the reading from Genesis on Christmas Day.
The Apollo Program (1963 - 1972). 30th Anniversary of Apollo 11 - July, 1999. The Apollo program was designed to land humans on the Moon and bring them safely back to Earth. Six of the missions (Apollos 11, 12, 14, 15, 16, and 17) achieved this goal.Apollos 7 and 9 were Earth orbiting missions to test the Command and Lunar Modules, and did not return lunar data.Apollos 8 and 10 tested various components while orbiting the Moon, and returned photography of the lunar surface. Apollo 13 did not land on the Moon due to a malfunction, but also returned photographs.he Apollo mission consisted of a Command Module (CM) and a Lunar Module (LM). The CM and LM would separate after lunar orbit insertion. One crew member would stay in the CM, which would orbit the Moon, while the other two astronauts would take the LM down to the lunar surface.
