STS-135: Crew arrives for TCDT as MFV work begins on SSME-3

Multiple efforts are under way for Atlantis’ STS-135 launch preparations, as her four member crew arrived at the Kennedy Space Center (KSC) for the Terminal Countdown Demonstration Test (TCDT). As engineers check the health of External Tank ET-138′s stringers, following last week’s Tanking Test, the replacement of a Main Fuel Valve (MFV) on Space Shuttle Main Engine 3 (SSME-3) is now in work.

As part of her nominal flow, Atlantis received her payload on Monday, after it was transferred from the payload canister into the Payload Checkout Room (PCR), prior to being installed into her cargo bay.

However, the actual arrival of the payload at the pad – at the end of last week – provided its own challenge, following issues with the canister once it had risen into the Rotating Service Structure (RSS).

“S0600 Vertical Payload Operations: On Friday morning during standard Payload canister alignment for canister door opening, a loud popping noise was heard and one of four canister brackets attached to retract cables,” noted the NASA Test Director (NTD) report (L2).

The bracket in question is used in conjunction with the retract cable to pull the canister to the RSS after hoisting operations.

However, following an engineering evaluation, it was determined that it was safe for operations to proceed, allowing the Payload to be successfully transferred to the PGHM (Payload Ground Handling Mechanism) in the PCR. 

“Engineering processed a MR (Material Report) to use alternate locations in place of the broken bracket to allow for Payload Canister door closure and to let the canister back out to its nominal hanging angle prior to lowering,” added the NTD. “This bracket is not used during the actual canister lowering operation.

“The Payload community analyzed the effects of the failed bracket and determined that the Payload did not see any excessive loads. Canister lowering was completed late Friday night.”

With the RSS moved back into the mate position on Saturday morning, Atlantis’ Payload Bay Doors (PLBDs) were opened to allow what was to be the final payload installation on an orbiter. This was completed on Monday.

Pyramyd Airsoft Blog: WE Hicapa Series - Blowing Apart the ...

So I wanted to investigate the world of CO2-powered Airsoft gas blow back pistols to see if a WE Hi-Capa 5.1 is as "CO2-Compatible" as WE says it is. Knowing very little, but enough to know that CO2 is a more powerful gas than the commonly used Airsoft Green Gas or Propane, I had my suspicions as to whether this was truly true.  Yup.  I said it, you read it: Truly true.  So back into my Airsoft Man Cave I went and made ready for exploratory Airsoft surgery. I took the entire slide apart, including the removal of the valve inside the loading nozzle (also called the "loading muzzle") and didn't see anything at first. Then, after closer examination of the nozzle, I noticed something glaring at me. That "something" looked like this...
