ammonia flakes floating out as they were attaching the fluid lines and that would decontaminate space suits for the next one on the agenda. i guess later tonight we will know for sure whether the cooling system actually has been repaired. yeah. that will basically justify the preliminary approval of the bump test. the pressurization will happen around 9:00 eastern time tonight. both are back up and running in unison. the science research that has been on hold for the past two weeks and finally resumes. this christmas eve space walk did have its befestive moment. best christmas ever. thanks, guys. juthat was fantastic work. merry christmas to everybody.
