Now that Sen. John Glenn is home safely, his plans include working with students at Ohio State University and his alma mater, Muskingum College.Glenn, 77, ended the mission in which he was the oldest man to travel in space after the shuttle Discovery STS-95 landed Saturday. Glenn has no plans to return to space.NASA spokesman, James Hartsfield said that this was an excellent end to the mission.”It was a picture perfect landing,” Hartsfield said. “The crew was happy to be home.””Particularly John Glenn,” he said, “Who minutes after landing said ‘I want to repeat a statement I made a long, long time ago, except this time it’s one-G and I feel fine.’Hartsfield said that in 1962 from the Friendship 7 capsule Glenn said, “It’s zero-G and I feel fine.”One member of Discovery suffered an injury. Stephen Robinson smacked his head when he came out of a tunnel while he was weightless. Robinson has a one-inch laceration over his right eye and is embarrassed to explain this to reporters, according to the Associated Press.In his first post-flight news conference, Glenn told the Associated Press, “he didn’t feel too hot” when he stood and walked out of Discovery on Saturday. Glenn did accompany his crew mates, however, for the traditional walk around the shuttle.”I feel very elated that things went well. We got a lot of data we were looking to get and worked very hard up there,” he told the Associated Press his first morning back on Earth.”Obviously, we’d like to… go right back up again, but that’s not to be. And so a sense of accomplishment I guess I feel and a little bit of letdown that the whole thing is over, maybe, but nothing serious.”Glenn said the Discovery mission was every bit as satisfying as his history-making ride abroad Friendship 7 in 1962.Glenn is now at the Johnson Space Center in Houston for a welcome back ceremony and will have three more weeks of medical tests.
