[b]Conjunction Update:[/b] When a conjunction prediction last night (8:00pm EDT) for a piece of Kosmos 2421 debris showed a miss distance of 0.67 km at a TCA (Time of Closest Approach) of ~10:00am this morning, leaving insufficient time for calculating & executing a DAM (Debris Avoidance Maneuver) with SM propulsion, Safe Haven instructions were uplinked to the crew. Subsequent tracking data reduced the PC (Probability of Collision) drastically, and when it approached zero this morning, "Safe Haven" was called off. [i][For the Safe Haven scenario, the crew would have relocated the Airlock PCS (Portable Computer System) laptop to the SM, then closed out and egressed the two Kibo modules (JLP, JPM), COL, Node-2, US Lab, Node-1/PMA-1, closing all hatches to the RS (Russian Segment), which contains ECLSS, and then retreating to the Soyuz crew return vehicle to await TCA.][/i]
