If you're one of a few people who can afford a $55 million ticket to space, you're not used to hard labor. The crew of the International Space Station complained that they had too much work to do when they were in low Earth orbit.

During a press conference on Friday, the four-man crew of Axiom Space admitted that they tried to fit too much into their schedules, which ended up putting a strain on them as well as on the astronauts that were already living and working on the mission.

The arrival of the Axiom personnel seemed to have a larger-than- expected impact on the daily workload on the professional International Space Station crew.

On April 9, the crew of the International Space Station arrived with an impressive experimental payload that included experiments on human cells, high-precision optical lens, and holograms. Some of the experiments that they did in space took a lot longer than expected because they are not professional astronauts or researchers. One experiment that was supposed to take just two and a half hours based on pre-flight training ended up taking double that amount of time, according to Larry Connor, who was a member of the Ax-1 mission.

The pace was very aggressive, especially early in the mission, according to a former NASA astronauts who commanded the mission.

The mission was originally supposed to last for eight nights, but was extended due to weather delays. It was a blessing to have the extra time above Earth, as it allowed the first-timers to take in the extraordinary views that they surely expected for the price of admission.

The space station remained cramped with 11 astronauts onboard. Some of the science modules only allow for four astronauts or fewer to conduct experiments at the same time, which meant that the Axiom-1 crew ended up slightly disrupting the schedules of the regular astronauts.

The company is preparing for the launch of the second crew to the International Space Station, having sold three seats, including one for a person from the United Arab Emirates.

Following the first private crew mission to the International Space Station, the private space company was having a discussion with NASA and SpaceX.
