What happened to the astronauts of Apollo 13 after the landing?

Why was the first moon landing significant?
The first moon landing was a stupendous technical achievement, and probably remains to this day the most remarkable accomplishment of the human race. It is so difficult to travel to the moon and return safely to Earth that it is quite amazing that we were able to do it. Aside from that, the moon landing was significant in a number of other ways. Because the US was able to do this when the USSR wasn't, the moon landing became part of the international public relations competition between the western world and the Soviet bloc. The Soviet Union, which always claimed to be superior to the decadent capitalist west in every way, obviously wasn't. The moon landing was also inspiring to a generation of scientists, who went on to create much more technology which has transformed the world very profoundly, since the moon landing in 1969, and which has made it possible for you & I to have this discussion on the internet.

Fuel is so useful to spacecrafts because without the fuel the spacecraft would not go.
Why did the Apollo 13 spacecraft have a parachute?
The same reason why all spacecrafts have parachutes: During reentry into the Earth's atmosphere, the spacecraft goes extremely fast. And if there are people in the spacecraft and no parachute, they would slam into the water at that speed and it would be like hitting concrete. So without a parachute, everyone on the spacecraft would be killed.

What is the probability of a penny landing on heads?
Simple question, difficult answer. It depends on how many times you want the penny to land on heads. The probability of a penny landing on heads once is 1 in 2. For it to land on heads twice is 1 in 4, for three times it is 1 in 8, and so on and so forth.
