Trip outside the 200th space on the International Space Station

In the evening of 12/5 (in Vietnam time), two American travelers began the 200th outer space walk to carry out some maintenance and scientific research work outside the International Space Station (ISS). ).

The walk of veteran astronaut Peggy Whitson, 57, and her colleague Jack Fischer, 43, started at 8 pm on May 12 (Vietnam time), two hours later than originally expected by the US Aerospace Agency (NASA) to detect water leaks in Fischer's astronaut clothes.

According to NASA, technical errors occur in central maintenance and cooling equipment (SCU), which provides electricity and oxygen to the traveling suiter's outfit.

However, spacewalks can still be done with just one active SCU. Therefore, NASA experts agreed to allow travelers to use SCU and replacement batteries in turn to power travel suits.

Spacewalks usually take about 6.5 hours. However, the 200th walk will be shortened to 4 hours due to the late departure after the incident.

Tourists who will perform ExPRESS Carrier Avionics (ExPCA) tasks replace 91kg, which provides power, data transfer and commands for internal ISS experiments. This is Whitson's ninth spacewalk, a record for a female traveler, and Fischer astronaut's first walking out into space.

Previously, NASA had many times encountered water leaks inside the travelers' helmets. Notably, the space walk in 2013 when the Italian astronaut Luca Parmitano had to shorten the journey time and was forced to return to the space laboratory in an emergency.

NASA's white travel suits are deteriorating after four decades of use.
