I want to know the answer to the following question:
John Glenn's spaceship was named what when he orbited the Earth?
All the background I'm provided with is that "His Mercury-Atlas 6 mission completed three orbits in the Friendship 7 spacecraft, and splashed down safely in the Atlantic Ocean, after a tense reentry, due to what falsely appeared from the telemetry data to be a loose heat-shield.". Is that enough to answer the question?
