Flight Controllers Develop Workaround to Bypass Suspect Filter

A routine disposal overboard of waste water and urine collected aboard Atlantis was terminated early. It is not necessary to dump the now half-full collection tank before landing Friday. Flight controllers have a workaround available for the crew to bypass a suspected clogged filter and dump the liquid, if landing is delayed.

The STS-129 astronauts began their sleep shift at 5:28 p.m. EST and will awaken at 1:28 a.m. Thursday. Atlantis’ first landing opportunity is Friday at 9:44 a.m. at Kennedy Space Center in Florida.
