Why is John Glenn important?

Answer 1

he is the only astnot to go in space 2 times the first time he went to the moon John Glenn was the first AMERICAN man to orbit in space. However, the Russians beat the Americans to it by 10 months. He has also made space history again when he went back into space in 1998. At this point in time, he was already around 76 or 77 years old- thus he is the oldest man ever to go in space. Why? He was a participant in an 'experiment' to test the effects going into space has on an aging person. (It had been discovered that going into space showed signs of premature aging). All of this information is accurate and taken from many other accurate resources. I hope this helped
