The six-member Expedition 40 crew began its workweek on a wide variety of tasks to advance scientific knowledge to benefit humanity, prepare a cargo ship for departure and maintain the International Space Station.

The space residents began their day measuring their body mass using Russian hardware. The crew members individually attached themselves to a device which applied a known force to the bodies with the resulting acceleration being used to calculate their body mass.

Commander Steve Swanson worked throughout Monday inside the Tranquility node refurbishing the Carbon Dioxide Removal Assembly (CDRA). During his first task in the morning he removed and replaced the desiccant/sorbent bed. Upon completing that job he checked for leaks and cleaned filters inside the CDRA.

After lunch, Swanson got right back to work on the CDRA with more leak checks and filter cleanings and replacements. Finally, the commander reassembled the CDRA returning the device back to operation.

German astronaut Alexander Gerst teamed up with Swanson helping him with the CDRA maintenance work throughout Monday. Gerst primarily assisted the commander with filter cleanings, filter replacements and finally the CDRA reassembly.

NASA astronaut Reid Wiseman spent his morning with life science work drawing his urine and blood samples for stowage in a science freezer. He also assisted Swanson gathering CDRA debris samples with a vacuum bag during the commander’s maintenance work.

In the afternoon, Wiseman worked in the Tranquility node’s Waste and Hygiene Compartment, the station’s bathroom, removing and replacing a pre-treat tank. He also monitored fluid flow in the device using a ruler and marker. Finally, Wiseman conducted a vision test using an optical coherence tomography laptop computer.

The Expedition 40/41 trio of Max Suraev, Wiseman and Gerst got together Monday afternoon to practice their medical proficiency. They practiced communication and coordination necessary to manage an emergency on the station.

The three cosmonauts Max Suraev, Oleg Artemyev and Alexander Skvortsov were in the Russian segment of the orbital laboratory Monday working on their complement of station science and maintenance.

Skvortsov teamed up with Suraev for the part of the morning and afternoon taking photographs of Earth to document the ecological effects of industrialization for the Ekon study. Skvortsov later prepared the Splanh experiment for upcoming work with the gastroenterological study. Towards the end of the day the veteran cosmonaut participated in a hearing assessment.

During the morning, Suraev, another veteran station resident, downlinked data gathered for the Obstanovka experiment to a laptop computer. Afterward, he pressurized the Elektron, the Russian oxygen generator located in the Zvezda service module, prior to activating the device. In the afternoon, he set up the VIRU virtual training software to study for the Relaxation experiment using 3-D manuals rather than the actual science hardware.

Artemyev, a first time space-flyer, started his day with a hearing assessment. He then partnered with Skvortsov for communications gear and headset checks. He later checked backup communication gear in Zvezda.

During the afternoon, Artemyev stowed gear for disposal inside the ISS Progress 55 (55P) resupply craft and updated the station’s inventory management system. The 55P is due to depart the station July 21 for a fiery disposal over the Pacific Ocean. Finally, he connected a television camera to the Rassvet module’s video system.
