NASA canceled the spacewalk due to this massive leak; Details inside | – vopbuzz
spacewalkOriginally planned to last about seven hours, the program was abruptly canceled after Dyson reported a leak in the spacesuit’s cooling system. This malfunction occurred shortly after the astronauts switched their suits to battery power; this was a standard procedure marking the beginning of the spacewalk. Barratt stated that there was “water everywhere”, stating the seriousness of the leak that posed a risk to the safety of the astronauts and the success of the mission.
The planned EVA involved removing a faulty communications box and collecting microbe samples from outside the station. These operations are vital to the continued functionality and scientific output of the ISS. However, the safety of the crew takes precedence over all other considerations. The decision to cancel the spacewalk was made quickly by Mission Control, demonstrating NASA’s commitment to the astronauts’ well-being.
This isn’t the first time spacesuit problems have disrupted planned EVAs. Another spacewalk was postponed earlier in the month due to “spacesuit discomfort” experienced by another astronaut. The complexity and precision required for spacewalks mean that even the smallest problems can have significant consequences, requiring extreme caution.
The leak was determined to be from the maintenance and cooling umbilical (SCU) in Dyson’s suit. The SCU is designed to connect to the ISS airlock to provide power, oxygen and cooling to the suit as astronauts prepare for EVA. The malfunction led to ice crystals forming inside the airlock and a “blizzard” of sorts, as Dyson explained to Mission Control. The astronauts were still inside the hatch and the outer door was open when the leak occurred, and they immediately closed it after the spacewalk ended.

The abort of the spacewalk, which lasted only 31 minutes from the time the suits switched to internal power until the crew airlock was re-pressurized, added to Dyson’s total EVA time of 23 hours and 20 minutes across the four spacewalks and Barratt’s total EVA time of 5 hours. Hour 37 minutes on three EVAs. The incident highlighted the unpredictable nature of space exploration and the challenges faced by astronauts working in the harsh environment of space.
NASA’s response to the incident was measured and transparent; officials were providing updates and assurances that the astronauts were not in danger. The agency’s ISS blog and subsequent briefings are expected to provide additional information about the incident and the measures taken to prevent future incidents.
The next spacewalk, scheduled for July 2, remains uncertain as NASA assesses the situation. The agency’s ability to adapt and respond to such challenges is a critical component of its continued success in space exploration. The incident serves as a reminder of the risks inherent in space travel and the importance of strict safety protocols. While NASA investigates the cause of the leak and works to ensure the reliability of its equipment, the determination and resilience of astronauts and ground crews continues to inspire and drive humanity’s presence in space.
