All ISS systems continue to function nominally, except those noted previously or below. Sunday - first day alone for CDR Whitson, FE-1 Malenchenko and FE-2 Anderson. Day 136 for Anderson. Ahead: Week 1 of Increment 16 (Increment 15 lasted 26 weeks, four less then Inc-14).
Yest posadka! (We have Landing!) Welcome back home, Fyodor Yurchikhin, Oleg Kotov (Russia's Cosmonaut No. 100) and Muszaphar Shukor! After 197 days in space (195 aboard ISS), Soyuz TMA-10/14S, carrying two-thirds of the Expedition 15 crew plus the Malaysian SFP, landed successfully this morning at 6:36am EDT in the steppes of Kazakhstan, with the crew in excellent condition. Touchdown occurred ~340 km short (west) of the intended site near Arkalykh. After arrival of the recovery forces, the crew was reported to be out of the spacecraft at about 6:55am. They were flown to Kustanai, Kazakhstan, with Star City near Moscow their next stop later today. Mission length for Yurchikhin & Kotov: 196d 17h 5m; for SFP Shukor: 10d 21h 14m. [Undocking from the ISS SM aft port was at 3:14am, deorbit burn from 5:47am-5:51am. According to TsUP/Moscow, the trajectory undershoot of the returning 14S Descent Module by about 340 km at touchdown was due to a switch of the on-board computer to the (secondary) Ballistic Descent Mode (BS), reported by the crew at 6:18am, instead of the lift-vector-controlled reentry using banking maneuvers (roll angle changes) commanded by the (primary) Automatically Controlled Descent Mode (AUS). An official commission has been formed to investigate the computer glitch which appears similar to the one experienced during the re-entry of Soyuz TMA-1 with the Expedition 3 crew of Ken Bowersox, Nikolai Budarin and Donald Pettit on 5/3/03. Instead of flying on the closed-loop-guided trajectory designed to reduce peak deceleration & heating while extending the downrange, the ballistic mode results in a steeper trajectory, ~2g's higher deceleration forces on the crew (7g max instead of 5g), and an undershoot of around ~250 mi. The crew was never in any increased danger, and the SAR (Search & Rescue) personnel did not require any additional time to reach the capsule, which they reportedly had in sight during parachute descent from ~4600m altitude down.]
The ISS crew, currently asleep since ~7:00am EDT, has an unusual day: off-duty with wake-up tomorrow morning at 1:00am & bedtime at 4:30pm (to 1:00am Tuesday).
After Soyuz departure at 3:14am, FE-1 Yuri Malenchenko manually closed the PEV (Pressure Equalization Valve) between the Service Module (SM) and its docking port vestibule and later restored the onboard communications system (STTS) setup which had been configured for Soyuz undocking and descent, including the VHF comm link from the TMA-10 SA to TsUP via RGS (Russian Ground Site).
Peggy Whitson performed the daily maintenance of the SOZh (Environment Control & Life Support System, ECLSS) system in the SM, including the ASU toilet facilities systems/replaceables.
Working on the IMS (Inventory Management System), Whitson updated/edited its standard "delta file" on the Russian VKS (Auxiliary Computer System), including locations, for the regular weekly automated export/import to its three databases on the ground (Houston, Moscow, Baikonur).
The new ISS CDR also restored the onboard video configuration in the Lab by disconnecting the UOP DCP (Utility Outlet Panel/Display & Control Panel) bypass power cable from the Lab RWS (Robotics Work Station) which was required for video coverage of the Soyuz departure.
During the undocking, structural dynamics data were taken (and subsequently downlinked via S-band) by the external S0 truss-mounted SDMS (Structural Dynamics Measurement System). [SDMS is ground controlled and can store only about 10 minutes of data before starting to overwrite its buffer; thus, SDMS took data only from 2 minutes prior to 3 minutes after the undocking.]
Shortly before bedtime this morning, Clay Anderson terminated the 24-hr data collection of the heart rate study of the CCISS (Cardiovascular & Cerebrovascular Control on Return from ISS) experiment, downloading the Holter Monitor and Actiwatch data, then stowing the CCISS hardware.
