According to a CNN report, astronauts aboard the International Space Station (ISS) have detected an unpleasant odor emanating from the Russian Nauka module. The odor was described as “a bit of an off-gassing” by NASA officials. While the cause of the odor is currently unknown, it is not considered a safety concern. The Nauka module, also known as the Multipurpose Laboratory Module, was launched and docked to the ISS in July 2021. It is designed to provide additional living space, storage, and research facilities for the Russian segment of the space station. NASA and Roscosmos, the Russian space agency, are working together to investigate the source of the odor and determine if any action needs to be taken. The ISS crew is trained to handle various contingencies and has procedures in place to address such situations. The report emphasizes that the odor does not pose any immediate risk to the astronauts or the station’s operations.
