Vanguard continued to transmit data for seven years, and while Sputnik reentered Earth's atmosphere sometime in 1958, scientists say that because of its solar cells, Vanguard will remain in orbit until at least 2109.
In addition to the satellite that failed to leave Earth in December 1957, visitors to the National Air and Space Museum can see a backup satellite from the successful March 1958 launch. Both are located in the Museum's Space Hall, where they serve as important reminders of American ingenuity and persistence.
