any idea when the CTC on the SSPDM will be installed on ELC-4?

After STS-135.

During STS-135, the RRM will be installed onto the SPDM EOTP. After 135 departs, the SPDM will perform an RPCM R&R on the P1 Truss, using the CTC to retrieve the new RPCM / stow the old RPCM. The CTC and RRM will then be installed onto ELC-4.

From ISS On-Orbit Status Report for 27/06/2011.

In Node 2, FE-3 Ron Garan installed and checked out the CBCS (Centerline Berthing Camera System) at the nadir port for the MPLM (Multi Purpose Logistics Module) "Raffaello" berthing after arrival of STS-135/ULF-7.

Progress M-11M will perform two reboosts of ISS orbit on June 29th at 12:20 UTC and on July 1st at 12:00 UTC (dV1 = dV2 = 2.1 m/s, dT1 = dT2 = 1985 s, dH1 = dH2 = 3.6 km).

I believe the crew is taking safe haven in the Soyuz' due to debris.  I was headed out the door but the crew was securing hatches in the US segment and I thought I heard a Russian call of 1208 for the debris. No Debris avoidance maneuver was possible per a call from Moscow.  I  missed the actual call to the crew of debris but several planned tag-ups were deferred.  There was a fire training event this morning but I heard the termination call for that and I don't believe this is part of the exercise.

Red conjunction confirmed, crew sheltering in the Soyuz. Probability of Collision (PC) is 00010.

Targeteer posted hearing 1208, which I take to be GMT, which is in about 10 minutes.

Thanks, we'll be watching. Any ID on the object?

The crew, of course, is sheltering in TWO Soyuzes.

The degree of 'buttoning up' seems to be still under discussion in recent months, so I'm presuming the hatches are not fully closed and dogged down. The volume of the station gives plenty of time to complete isolation if there actually is a hit causing an air leak. Much more likely than that is a solar array hit causing annoyance. MOST likely is nothing at all happens.

Standard procedure is for all USOS hatches to be closed, and IMV (Inter Module Ventilation) shut off. I don't know about the hatches on the Russian Segment, but the Soyuz hatches are supposed to be closed per a NASA agreement. I saw a NASA calculation that gave three minutes from an impact (causing a tennis-ball sized hole in a module) to total depressurisation.

Predicted miss distance about 250 meters...predicted time of closest approach shortly.

And that's apparently over, unknown object came and went.  Going to stand by for a little bit, but will shortly back out of this "shelter in place."
