Privately funded American space company Axiom Space successfully finished its Ax-4 mission on Tuesday morning, returning astronauts from India, Poland, and Hungary from the International Space Station, and safely splashing down off the Californian coast.

However, the increasing privatization of space access raises questions about America's future role in space exploration. While another private company, SpaceX, currently provides the only means for launching astronauts from U.S. soil, Oluseyi emphasized the importance of maintaining both public and private investment in space.

It was Axiom's fourth mission to the space station, part of NASA's effort to open up space to more businesses and people.
