A replacement Air Quality Monitor will be launched on the next Progress resupply mission to aid the investigation into increased levels of benzene in the International Space Station’s atmosphere

The first detection of off-nominal levels occurred on April 13, when Air Quality Monitor-1 – or AQM-1 – detected benzene in the atmosphere that was slightly above the reporting limit

From April 13 to April 29, the amount of benzene in the atmosphere of the ISS remained around 0.065 mg/m^3

The investigation into the benzene levels will now remain on hold until a brand new AQM arrives on board the next Progress resupply spacecraft to launch and dock to the ISS, Progress 76P (also known as Progress MS-15)
