An alarm sounded during SpaceX’s Inspiration4 mission. Here’s why

It has emerged that SpaceX’s first all-civilian crew experienced an emergency situation during the groundbreaking Inspiration4 mission earlier this month.

At some point during the three-day spaceflight, an alarm alerted the four Crew Dragon passengers to an issue with — of all things — the toilet.

A faulty space toilet may sound rather trivial when you consider other things that you really wouldn’t want to go wrong while orbiting 357 miles (575 kilometers) above Earth. But the issue could have resulted in waste products floating around the spacecraft in the microgravity conditions, causing serious problems for those on board.

Shortly after the four nonprofessional astronauts returned home just over a week ago, SpaceX CEO Elon Musk acknowledged in a tweet that the all-civilian Inspiration4 mission “had some challenges” with the toilet, though he didn’t go into detail.

The problem centered on the toilet’s fans, which create suction to quickly remove waste matter before it has a chance to start floating around. According to a CNN report, the fans developed a fault that set off the alarm.

Asked recently about whether the problem had led to a messy situation aboard the Crew Dragon, mission commander Jared Isaacman said: “I want to be 100% clear — there were no issues in the cabin at all as it relates to that,” adding that “nobody really wants to get into the gory details.”

To the relief of everyone aboard the spacecraft, the issue was fully resolved, “so there was nothing ever like, you know, in the cabin or anything like that,” Isaacman said.

SpaceX redesigned its Crew Dragon for the Inspiration4 mission. As the spacecraft wasn’t heading to the International Space Station, the docking mechanism was able to be replaced with an all-glass dome to provide the most expansive views ever offered by a spacecraft of that size.

The toilet was also placed in the same area, with a bathroom visitor able to pull a curtain across for privacy whenever nature called.

Despite the toilet trouble, the mission was declared a success and could pave the way for a full-fledged commercial service for private citizens.

SpaceX launched the mighty Starship for the first time in April last year, but it took a full seven months before it became airborne again.

Following the second test flight in November, SpaceX managed to get the Starship off the launchpad again just four months later in a spectacular flight that took place last week.

SpaceX has put a Crew Dragon on Pad 40 at the Kennedy Space Center in Florida for the first time. This means that going forward, SpaceX will have two pads to choose from when sending astronauts to space.

Up to now, crews launching on SpaceX’s Crew Dragon spacecraft lift off from Pad 39A at Kennedy, but having another launch site available gives NASA and SpaceX greater flexibility when planning missions by easing pressure on teams if scheduling issues and traffic conflicts arise.

SpaceX’s third Starship test flight last Thursday was its best yet, far exceeding the first two missions, which took place last year and ended in huge fireballs just a few minutes in.

This time, the Starship -- comprising the first-stage Super Heavy booster and upper-stage Starship spacecraft -- kept on flying, with both parts reaching their destination points before breaking up on descent.
