On September 29, NASA launched a $23 million advanced toilet and waste management system, which will be installed at the International Space Station (ISS). The toilet will be tested on the ISS before the model is replicated for future use on the moon and Mars. The advanced toilet system is 65% smaller and 40% lighter than the current toilets that are used at the ISS and can support larger crews. The units feed pre-treated urine into a regenerative system, which recycles water for use. To counter gravity, space toilets use airflow to pull urine and faeces from the body and into the proper receptacles. The unit also has an automatic start feature, which gets activated when the lid is lifted. This helps in odour control. The unit requires less clean-up and maintenance time, with more durable parts.
