Risky Spacewalk Back On For Wed.

Risky Spacewalk Back On For Wed.

The schedule shift, if approved Tuesday by NASA's mission management team, means the spacewalk would be under way at the same time NASA's $3.3 billion Cassini probe is braking into orbit around Saturn, reports CBS News Space Consultant Bill Harwood.Pending final approval, station commander Gennady Padalka and flight engineer Mike Fincke plan to open the Pirs airlock module's hatch around 5:40 p.m..

The scheduling conflict has forced NASA to scramble a bit to ensure both events can be televised live. A NASA producer said Monday if the revised schedule holds up, Cassini commentary, the braking maneuver and a post-orbit-insertion news conference would be carried live on NASA's normal satellite television channel, the one carried by many cable television companies. The spacewalk would be carried on another.

With CMG-1 already out of action due to an earlier problem, station managers want to get CMG-2 spun up and back on line as soon as possible to provide redundancy in case of additional failures down the road.Wearing Russian Orlan spacesuits, Padalka and Fincke began a repair spacewalk last Thursday, but they were forced to call it off after just 14 minutes when Russian engineers noticed a pressure drop in Fincke's primary oxygen tank.After troubleshooting, engineers concluded the problem likely was caused by a small handle Fincke repositioned as part of a standard pre-spacewalk procedure to test the suit's ability to deliver increased oxygen flow if required. When he reset the handle, a light indicated the oxygen flow was back at the normal level.But the switch apparently hung up slightly and oxygen continued flowing out of the primary tank at a higher-than-normal rate. Russian flight controllers believe the suit is in good health and new procedures have been developed to help the spacewalkers confirm the proper oxygen setting.
