The legend has landed
John Glenn says he feels fine
Mr Glenn, and his six crew mates, made a safe landing at Kennedy Space Centre, Florida, on Saturday, after travelling more than 3 million miles in space.
A press conference was planned for Saturday, but it was put off until Sunday on the advice of Nasa's chief doctor, Philip Stepaniak.
He said the conference would have added an unnecessary strain on the astronauts at the end of a long day,
He was able to walk unaided down the steps before being reunited with his family.
Mr Glenn even found the energy to call out on the communications link moments after landing, recalling his previous return to earth.
"This is PS2, I'm better known to a lot of you as John," he said.
Mission Control said that Discovery had completed a trip of 3.6 million miles and "a moment in history".
Nasa had put Edwards Air Base in California on stand-by in case of bad weather on the east coast.
There was also concern that a parachute, used to slow the shuttle down on landing, may open early.
The drag chute is not essential for landing and there were safeguard procedures for the crew if it had opened ahead of schedule.
The potential problem arose because a compartment door at the rear of Discovery fell off as the space shuttle blasted into space.
More than 250,000 people gathered around Kennedy Space Centre to watch the launch. From VIP seats inside the base President Bill Clinton and a host of Hollywood saw the misson blast off.
Mr Glenn has been taking part in a series of experiments, including assessing the effects of weightlessness on the body.
Scientists hope to use the results of the experiments for research into the ageing process.
When Mr Glenn blasted off with six other astronauts he was the Democrat senator for Ohio.
Following the US mid-term elections, in which Mr Glenn retired as senator, he returns merely as an "American legend".
