The Expedition 42 crew worked Wednesday with fruit flies, a humanoid robot and a Dragon spacecraft. Also, Europe’s Automated Transfer Vehicle-5 fired its engines for nearly five minutes, slightly lowering the station’s orbit to prepare for an upcoming ISS Progress 58 resupply mission.

Commander Barry Wilmore and Italian astronaut Samantha Cristoforetti packed gear inside the SpaceX Dragon private space freighter for retrieval on Earth. The Dragon will return to Earth on Feb. 10 when it will splashdown in the Pacific Ocean for recovery off the coast of Baja California. Cristoforetti later fed fruit flies for an experiment studying their immune system as a model for a crew member’s susceptibility to disease in space.

Another spacecraft attached to the International Space Station, Europe’s Automated Transfer Vehicle-5 (ATV-5), will fire its engines Wednesday slightly lowering the station’s orbit. The lower altitude places the station at the correct altitude to receive the ISS Progress resupply craft when its launches Feb. 17. The ATV-5 will end its mission Feb. 14 when it undocks from the Zvezda service module for a fiery destruction over the Pacific.

The Combustion Integrated Rack (CIR), located inside the Destiny lab module, needs fuel so scientists can ignite materials to study the behavior of flames and smoke in space. Pieces of hardware that store and deliver fuel, including igniter tips, were replaced on the CIR Friday by Commander Barry Wilmore to keep the rack in operating condition.

Astronauts Terry Virts – with the help of Samantha Cristoforetti and doctors on the ground – participated in more eye checks, undergoing ultrasound scans and an echocardiogram to gather more information. The Ocular Health study seeks to understand how microgravity affects a crew member’s eyes and explain why some astronauts report impaired vision during their missions in space.

Virts also checked samples and transferred data collected for the Coarsening in Solid Liquid Mixtures-2 (CSLM-2) experiment, which offers potential benefits for consumer and industrial products. Cristoforetti checked on the station’s fruit flies, and later worked maintenance on the Magvector study that observes how Earth’s magnetic field interacts with an electrical conductor.

Ground controllers overnight remotely guided the Canadarm2, with its Dextre robotic hand attached, to deftly remove the CATS experiment from the SpaceX Dragon trunk. They then handed it off to the Japanese robotic arm for installation on the Kibo laboratory’s external platform. CATS, or Cloud-Aerosol Transport System, will collect data on the pollution, dust, smoke, aerosols and other particulates in Earth’s atmosphere to understand their impacts on global climate and create a better model of the climate feedback process.

Ground controllers have completed troubleshooting work after last week’s false alarm indicating an ammonia leak. Heat exchangers and thermal control systems on the U.S. side of the International Space Station have been recovered and reintegrated and are operating in excellent shape.

Commander Barry Wilmore was scrubbing cooling loops on a U.S. spacesuit when he heard an abnormally loud fan pump separator in the suit. He alerted spacesuit engineers who are currently discussing the problem on the ground.

Crew members over the weekend noticed a bad odor coming from Europe’s docked Automated Transfer Vehicle and closed its hatch. European controllers then performed waste tank leak checks and didn’t find any leak indications. Flight Engineer Alexander Samokutyaev is set to reenter the vehicle wearing a respirator mask to investigate.

The International Space Station residents were back at work Thursday after an ammonia leak indication sent the crew over to the Russian segment. Flight controllers determined there was no leak and NASA managers allowed the crew to resume normal activities and open the U.S. segment back up.

This week, the orbital residents kicked off several new experiments delivered Monday morning aboard the SpaceX Dragon commercial cargo craft. Italian astronaut Samantha Cristoforetti worked in Japan’s Kibo lab module feeding fruit flies for an experiment that will observe how long-term microgravity affects the immune system. NASA astronaut Terry Virts set up bacteria kits inside the Destiny lab’s Microgravity Science Glovebox for an experiment that explores the risk of infectious disease in space.
