Aboard the orbital laboratory, the current crew members, Commander Barry Wilmore and Flight Engineers Alexander Samokutyaev and Elena Serova, are working their scheduled task list of ongoing science and maintenance.

Wilmore opened the Fluids Integrated Rack to configure a microscope for the ACE-M-3 experiment. The advanced fluids study observes small particles suspended within a liquid that build into 3D structures. During the afternoon, the commander worked on Europe’s Kubik incubator that supports life science with organisms such as seeds, cells and small animals.

Commander Barry Wilmore worked in the Japanese Kibo lab module on the Aniso Tubule botany experiment that studies how roots adapt to gravity. After lunch, Wilmore went back to more hardware replacement work on the Combustion Integrated Rack that he began Tuesday. At the end of the day he configured a maintenance work area for upcoming operations of another botany study, the Seedling Growth experiment.

Flight Engineer Alexander Samokutyaev worked in the Russian segment venting gas from an air conditioner. He was assisted by his fellow cosmonaut Elena Serova who also installed gas analyzer hardware and cleaned vents. The duo partnered up later in the day for a new chemistry education experiment with participation from Russian school children.

The next Expedition 42 trio waiting to join the International Space Station crew conducted final Sokol launch and entry suit fit checks at the Baikonur Cosmodrome in Kazakhstan. NASA astronaut Terry Virts, Roscosmos cosmonaut Anton Shkaplerov and European Space Agency astronaut Samantha Cristoforetti are making final preparations before Sunday’s launch at 4:01 p.m. EST to the space station aboard the Soyuz TMA-15M spacecraft.

Flight Engineer Alexander Samokutyaev replaced a battery module in the Zvezda service module then repaired and photographed an air duct. His fellow cosmonaut, Elena Serova, checked Russian sensors that monitor air pressure then proceeded with disinfectant work to prevent microbial growth in the Zarya module.

A new trio of Expedition 42 crew members is relaxing at the Cosmonaut Hotel crew quarters in Kazakhstan. Soyuz Commander Anton Shkaplerov and Flight Engineers Terry Virts and Samantha Cristoforetti played games, had medical checks and planted trees during a traditional ceremony Tuesday.

Their Soyuz TMA-15M spacecraft is being readied for its roll out to the launch pad at the Baikonur Cosmodrome on Friday. The new crew will launch aboard the Soyuz on Sunday for a near six-hour ride to the International Space Station’s Rassvet module.

His fellow crew members, Flight Engineers Alexander Samokutyaev and Elena Serova, worked on routine maintenance tasks and cargo transfers in the station’s Russian segment. They also paired up for a cardiovascular exam on an exercise bike, sampled the station’s atmosphere and tested television downlink signals.

The next trio to join Expedition 42 is in Kazakhstan counting down to a Nov. 23 launch aboard a Soyuz TMA-15M spacecraft. They are set for a near six-hour ride to the International Space Station where they will live and work until May 2015.

The three orbiting Expedition 42 crew members are wrapping up the work week with science, cargo transfers and maintenance. Meanwhile, another crew is on the ground awaiting its launch from the Baikonur Cosmodrome in Kazakhstan.

Commander Barry Wilmore worked in the Kibo laboratory checking out the lab module’s robotic arm. He was also in the Destiny lab module studying plants, which can provide oxygen and food for future crews, for the Seedling Growth experiment. His fellow crewmates Alexander Samokutyaev and Elena Serova worked in the station’s Russian segment off-loading cargo from the docked ISS Progress 57 resupply ship and reconfiguring networks.

The International Space Station is currently occupied by a trio of Expedition 42 crew members consisting of Commander Barry Wilmore and Flight Engineers Alexander Samokutyaev and Elena Serova. They are waiting for three more crew members, Soyuz Commander Anton Shkaplerov and Flight Engineers Terry Virts and Samantha Cristoforetti, who are counting down to a launch to the orbital laboratory in less than two weeks.

Meanwhile, the orbiting station residents are continuing microgravity research to improve life on Earth and in space. Wilmore collected blood and urine samples for stowage in a science freezer. Samokutyaev reconfigured computer systems in the station’s Russian segment. Serova took measurements of the station’s internal radiation environment and studied the vibrations the station experiences on orbit. Serova and Samokutyaev also participated in hearing tests.

Station Avoids Satellite Debris After ATV-5 Fires Engines

ISS Configuration as of Nov, 9, 2014
The International Space Station configuration as of Nov, 9, 2014, shows the docked ATV-5 on the aft end of the Zvezda service module.

The International Space Station’s “Georges Lemaitre” Automated Transfer Vehicle fired its engines for 3 minutes, 25 seconds at 6:35 a.m. Central time today in a Pre-Determined Debris Avoidance Maneuver (PDAM) to move well away from a small piece of debris from a spent Chinese satellite (Yaogan 12) launched in November 2011.

The maneuver, which was coordinated with Russian and European flight controllers, raised the station’s altitude by 9/10 of a mile at apogee and 2/10 of a mile at perigee and left the station in an orbit of 262.3 x 252.0 statute miles.

The maneuver substituted for a previously planned reboost of the station that had been planned for Wednesday night which would have been required regardless to place the station at the proper altitude for the upcoming launch of the Expedition 42/43 crew on Nov. 23, U.S. time, on a 4-orbit, 6-hour rendezvous to reach the station.

Without the maneuver, the debris would have passed within 7/10 of a mile of the station at 8:40 a.m. Central time. The three-person crew on the station was informed of the potential conjunction and maneuver plans on Tuesday and was never in any danger.
