\u201cThe launch window opens up at 1:31 p.m. EDT (launching 30 minutes later) on Monday, so tanking will be around 4:00 a.m. ET. The schedule will be sent out, if it hasn\u2019t been already, for the MMT times.\u201d<\/p>\n
Processing is continuing to work through pressurization tasks and closeouts, with the next item of interest being Payload Bay Door (PLBD) closure.<\/p>\n
\u201cOrbiter: OV-104 \/ ET-130 \/ BI-137 \/ RSRM-105 (Pad-A): The team continues to work preparations toward Launch Countdown; Call to Stations (CTS) is Friday at 1530 EDT. Hyper\/MPS (Main Propulsion System) pressurization\/closeouts are in-work,\u201d noted Wednesday processing information on L2.<\/p>\n
\u201cInitial OMS\/RCS GHe\/GN2 pressurization to flight mass was completed yesterday (Tuesday). MPS\/SSME GHe tanks are at flight pressure. Final (stage 2) OMS\/RCS GHe\/GN2 pressurization to flight mass began yesterday on 2nd shift and completed at 0255 local this morning.<\/p>\n

\u201cThe pad was reopened for normal work at 0338 local. QD (Quick Disconnect) leak checks and disconnects and flight cap installations are in work.\u201d<\/p>\n

Work through the weekend and early into this week to repair the two cracks on Atlantis\u2019 port radiator face sheet has been successful, following an accident involving a socket impacting the hardware during pad processing.<\/p>\n\u201cWork associated with the payload bay door radiator repair is complete,\u201d confirmed processing information. \u201cCleanup of some excess epoxy was completed, tape was installed over the doubler; and a 24 hour vacuum cure was completed \u201c<\/p>\n
Usual pad flow issues are expected ahead of launch, with the current \u201cIPRs\u201d (Interim Problem Reports) all cleared bar a potential requirement to shorten a Teflon tube that is interfering with Payload Bay Door closure.<\/p>\n
\u201cNew IPR to OMS\/RCS Engineering: Prior to pressurizing the LOMS (Left Orbital Manuevering System) GN2 tank a GSE valve (A89822) failed to open. Troubleshooting indicated an electronic fuse had failed,\u201d added Wednesday processing information.<\/p>\n
\u201cPersonnel briefly entered pad A between S0071 stage 1 and 2 press and replaced the card. Retest of The GSE (Ground Support Equipment) valve was successful and stage 2 pressurization proceeded normally.<\/p>\n
\u201cHoldfire voltage at lower limits update: The configuration in a communications panel inside MLP-2 (Mobile Launch Platform) was corrected and the range safety holdfire checks were successfully re-accomplished yesterday (Tuesday).<\/p>\n

\u201cPayloads picked up a PR (Problem Report) on a GN2 Teflon tubing potential interference with the PLBD during closure. The plan is to trim the Teflon tubing to take the slack out of it (reference photo). The constraint is to payload bay door closure.\u201d<\/p>\nThe tube in question is believed to be related to the Hubble servicing payload Atlantis is flying with, and used for gas transfer from one location to another. Engineers noted that a simple shortening of the tube will resolve the problem.<\/p>\n
\u201cIt\u2019s a busy week,\u201d added MMT chair Leroy Cain. \u201cWe\u2019re doing some work on the budget. We\u2019ll be traveling to Washington D.C. for a couple of days. We\u2019re getting ready to launch in a week.<\/p>\n
\u201cLet\u2019s keep our focus, and have a good week.\u201d<\/p>\n
STS-132 Crew Assignment:<\/p>\n
STS-132 will mark the 32nd and final \u201cscheduled\u201d flight of space shuttle Atlantis. Targeting launch No Earlier Than (NET) May 13, 2010, STS-132 is an 11+1+2 day mission, with three scheduled EVAs (spacewalks) and the option to add an extra EVA should the need arise.<\/p>\n
Recently baselined by the Program Requirements Control Board (PRCB), the ULF-4 flight will see the Russian Mini Research Module-1 (MRM-1) added to the International Space Station.<\/p>\n
The crew that will fly with Atlantis have been assigned, with Ken Ham selected as the mission\u2019s commander, along with Tony Antonelli, who will be piloting Atlantis.<\/p>\n
Karen Nyberg, Piers Sellers, Stephen Bowen, and Garrett Reisman will make up the rest of the crew as Mission Specialists.<\/p>\n

Engineers are pressing through the remaining minor issues \u2013 the latest being an obstructive Teflon tube in the Payload Bay \u2013 ahead of the start of STS-125\u2019s three day countdown that opens on Friday. Meanwhile, a veteran six person crew has been assigned by NASA for the STS-132 mission to the International Space Station (ISS).
