In a remarkable turn of events, an astronaut's health issue has led to NASA's first-ever medical evacuation from space, cutting their mission short by over a month. On Thursday, an astronaut experiencing health difficulties returned to Earth alongside three fellow crew members, concluding their time aboard the International Space Station (ISS) earlier than planned.
The return was orchestrated by SpaceX, which successfully guided the capsule to a splashdown in the Pacific Ocean, close to San Diego, during the early hours of the morning. This occurred less than 11 hours after the astronauts departed from the ISS. Their immediate destination post-landing was a hospital for necessary overnight observation.
NASA's newly appointed administrator, Jared Isaacman, addressed the situation following the splashdown, stating, "Clearly, we opted for this early return due to a serious medical condition. Fortunately, the astronaut involved is currently in good spirits and receiving appropriate medical evaluations."
This unexpected conclusion to the mission, which originally began in August, left the orbiting laboratory with only one American and two Russian astronauts remaining onboard. Both NASA and SpaceX are now exploring the possibility of expediting the launch of a new crew of four, with the current target set for mid-February.
The astronauts making the return included NASA’s Zena Cardman and Mike Fincke, Japan’s Kimiya Yui, and Russia’s Oleg Platonov. However, officials have chosen not to disclose the identity of the astronaut who faced health challenges last week or provide details about the specific nature of the medical issue, citing privacy concerns.
Despite the astronaut being stable while in orbit, NASA prioritized their return to Earth to ensure they could receive timely care and diagnostic assessments. Officials confirmed that the re-entry and splashdown process did not require any special modifications, and the recovery vessel had a standard team of medical professionals on board.
After splashdown, the astronauts exited the capsule individually within an hour, assisted onto reclining cots, and promptly transported for routine medical evaluations, all while waving to cameras. Isaacman oversaw the proceedings from Mission Control in Houston, accompanied by the families of the crew members.
Prior to the landing, NASA made arrangements for the entire crew to be taken directly to a hospital in the San Diego area, even conducting practice helicopter runs from the recovery ship to ensure a smooth transition. The astronaut in question is expected to undergo comprehensive medical examinations before potentially flying back to Houston with the rest of the crew on Friday, assuming everyone is deemed fit for travel. The status of Platonov's return to Moscow remains uncertain.
Throughout the past week, NASA has consistently emphasized that this situation was not an emergency. The astronaut became ill or sustained an injury on January 7, which led to the cancellation of a scheduled spacewalk by Cardman and Fincke the following day, ultimately resulting in the decision for an early return. This marks the first instance where NASA has curtailed a spaceflight due to medical reasons, although there have been similar occurrences in the past with Russian space missions.
Isaacman pointed out that the preparations for the spacewalk were unrelated to the medical incident. He also noted that it would be premature to draw any conclusions or make assumptions regarding the cause of the astronaut's condition at this stage, leaving open the question of whether this issue could have arisen had they been on Earth.
Historically, the ISS has successfully operated with only three astronauts onboard, and at times even two. NASA stated that they would be unable to conduct any spacewalks, even in emergencies, until the arrival of the next crew, slated to consist of two Americans, one French, and one Russian astronaut.
Isaacman remarked that it’s too early to determine if the launch of replacement station personnel will take precedence over NASA's upcoming lunar mission, marking the first time astronauts will go to the moon in over fifty years. The moon rocket is scheduled to be moved to the launch pad this weekend at Florida's Kennedy Space Center, with a fueling test anticipated by early next month. A definitive launch date cannot be set until these preparations are completed, although the earliest possible date for the lunar flyby could be February 6.
For the time being, NASA is balancing work on both the space station and lunar missions, with minimal personnel overlap, according to Isaacman.
"If we reach a point where we need to prioritize between these two human spaceflight missions, that will be a great challenge to have at NASA," he told reporters, emphasizing the agency's capacity to handle multiple significant projects simultaneously.
