ISS On-Orbit Status, 18-08-2003
Tomorrow, they will deinstall the ENA pump, working with
hack saw and bone saw to cut pipes and brackets. Seems to me that theree is a replaceable pump panel, but they decided to fix the panel instead of replacing it with a spare. (lack of cargo capacity during shuttle standdown might be the major reason). The 19-08-2003 status report adds more context: they today worked on the actual removal of the electric pump unit (ENA) from the SPN, using a hack saw and bone saw to cut pipes and brackets. The failed ENA will be returned on the next Soyuz. Could it be they are cutting it out so it can be returned to earth for failure analysis, rather than as part of the replacement procedure? Returning equipment on a Soyuz must be unusual. I guess they are concerned about the other loop failing, and want to understand the failure better. Richard -- Richard Wendland |
