In a national survey of 2,541 U.S. adults conducted March 27-April 9, 2018, roughly seven-in-ten Americans (72%) say it is essential for the U.S. to continue to be a world leader in space exploration. Strong public support is widely shared across gender, generational, educational and political groups. Also, some 80% of Americans say the International Space Station has been a good investment for the country.

In the decades since the U.S. landed astronauts on the moon, the landscape of space exploration has changed dramatically as other countries have expanded their capabilities and private companies have taken on larger roles. Some 65% of Americans believe that NASA's role in space exploration is essential, with 33% saying that private companies will ensure that enough progress is made in space exploration without NASA's involvement.
