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.
NASA's Apollo manned missions (1969 to 1972) took approximately 3 days to reach the Moon. Unmanned probes can take slightly longer to save fuel. Two Chinese probes launched inâ¦ 2007 and 2010 took different paths, the first taking 12 days and the second only 4 days on a direct route. 7 people found this useful.
