The six-member Expedition 43 crew ends its work week with a wide variety of science exploring life in space benefiting both crews in space and humans on Earth. Meanwhile, one space freighter is preparing to fire its thrusters to lift the station’s orbit as another is being packed and readied for splashdown.

One-Year crew members Scott Kelly and Mikhail Kornienko participated in the Fine Motor Skills experiment which monitors different phases of a crew member’s microgravity adaptation and recovery back on Earth. Commander Terry Virts took samples of air and surface microbes for the Microbial Observatory-1 study which will be analyzed by scientists on the ground.

Samantha Cristoforetti studied the physics of where fluids and gases meet in Japan’s Kibo lab module. Flight Engineer Gennady Padalka worked on video gear and tested magnetometers in the station’s Russian segment. Flight Engineer Anton Shkaplerov studied chemical reactions in the Earth’s atmosphere, checked Russian docking systems and photographed windows in the Pirs and Poisk modules.

The ISS Progress 58 resupply ship docked to the Zvezda service module will fire its engines Friday night. The orbital boost will place the International Space Station at the correct altitude for the undocking of Expedition 43 in early June. The SpaceX Dragon loaded with science and gear will be released from the grips of the Canadarm2 May 21 at 7:05 a.m. EDT for a splashdown in the Pacific Ocean a few hours later.

Full Release

The six-member Expedition 43 crew worked Tuesday on a wide variety of tasks. The International Space Station residents explored life sciences, trained for a robotics experiment, conducted maintenance and prepared for next week’s departure of the SpaceX Dragon cargo craft.

Astronaut Scott Kelly worked on an experiment which observes how a crew member’s fine motor skills adapt over a six-month and a year-long mission in space. He then moved on to training for the Robotics Refueling Mission.

Italian astronaut Samantha Cristoforetti worked on the Rodent Research experiment during the afternoon. Commander Terry Virts worked on cargo transfers to the Dragon space freighter which is getting ready for its May 21 departure and splashdown.

The three cosmonauts Anton Shkaplerov, Gennady Padalka and Mikhail Kornienko, worked in the Russian segment. The trio cleaned dust filters, changed out a smoke detector and downloaded results from a microbial air sampling.

Experiment Work Inside and Outside Station Wednesday

Canadarm2 and Dextre
ISS041-E-049099 (30 Sept. 2014) — The International Space Station’s Canadarm2 and Dextre is seen outside the SpaceX Dragon cargo ship.

The Expedition 43 lab assistants conducted biomedical science in the International Space Station on Wednesday. Meanwhile, controllers on the ground will remotely maneuver the Canadarm2 outside the station to experiment with the possibility of servicing satellites on orbit for longer missions.

The crew participated in a wide variety of life science studies. The Myco experiment, which analyzes nose, throat and skin samples, examines how microorganisms on the space station can affect a crew member’s allergies and illnesses. Another study, Interactions, explores how crews from different cultures learn to work with each other. More Rodent Research work took place, as the astronauts readied samples for return to Earth and checked out the rodents’ habitat.

Crew members also underwent medical exams, checking vital signs such as temperature and blood pressure. Later there were crew eye checks as doctors on the ground explore how microgravity affects vision.

The Robotics Refueling Mission, a joint study between NASA and the Canadian Space Agency, investigates satellite repair and servicing techniques in space. Operators on the ground use the station’s special purpose dexterous manipulator, better known as Dextre, on the end of the Canadarm2, for fine robotics manipulation. Engineers are looking to determine whether it’s possible to refuel satellites and test electrical connections robotically.

Cargo Craft Prepped for Departure as Crew Works New Science
