New York City welcomed the Apollo 8 crew with a ticker-tape parade on the 10th of January, Newark hailed them on the 11th, and Miami greeted them on the 12th during the Super Bowl game. The Astronauts returned to Houston on the 13th for a hometown parade. Incoming President Richard M. Nixon sent Borman and his family on an eight-nation goodwill tour of western Europe. Everywhere they went, the astronauts depicted the earth as a spaceship and stressed international cooperation in space.
Even a perfect reentry would subject the Apollo 8 command module to extreme stress. With Gemini, the capsule re-entered from Earth orbit, but Apollo 8 would re-enter at approximated 25,000 miles per hour. The forces of heat and deceleration would be much greater.
