The space tourism industry is booming in 2021

Sixty years to the day that NASA astronaut Alan Shepard became the first American in space aboard the Freedom 7 rocket, U.S. business leaders are continuing to help the country make major strides in space exploration.

Since Shepard's 15-minute, 116-mile May 5, 1961 flight – on the heels of Soviet cosmonaut Yuri Gagarin's flight – the U.S. has landed humans on the moon and sent more than 150 NASA astronauts to the International Space Station (ISS) for important scientific research

In addition, The Associated Press reported Wednesday that 579 people have entered space, with nearly two-thirds of the crew members American.

Spaceflight has dramatically changed over the past few decades, with the introduction of "space tourism."

Japanese billionaire Yusaku Maezawa and eight dearMoon contest winners are slated to launch onboard the SpaceX Starship for the trip of a lifetime in 2023.

Musk is not the only one with skin in the game. 

Bezos' Blue Origin – which filed a protest regarding NASA's decision on the HLS contract -- said Wednesday it would auction off a seat for the company's first crew spaceflight aboard the rocket New Shepard.

That flight is targeted for the anniversary of the July 20 Apollo 11 moon landing.

Virgin Galactic's Branson also aims to begin tourist spaceflights in 2022.
