Crew Gets a Breather Before SpaceX Departure

SpaceX Dragon CRS-6
ISS043E190604 (05/13/2015) — SpaceX’s Dragon cargo capsule is seen here docked to the Earth facing port of the Harmony module. SpaceX’s sixth commercial resupply flight to the International Space Station launched on April 14th and arrived three days later. It will depart with over 3,100 pounds of research samples and equipment and splashdown in the Pacific Ocean on May 21.

The USOS crewmembers worked a reduced day today as they prepare to sleep shift in preparation for SpaceX-6 departure on Thursday.

The crew performed a checkout of the Commercial Orbital Transport Services (COTS) UHF Communication Unit (CUCU) that the crew will use to communicate with the Dragon capsule while it is flying free in the vicinity of the station. They also continued loading the final cargo items onto Dragon which will return about 3,100 pounds of experiment samples and other hardware.

One-Year crew member Mikhail Kornienko took samples for the Fluid Shifts experiment, an investigation into the suspected cause of astronaut vision changes while in microgravity. ESA (European Space Agency) astronaut Samantha Cristoforetti also performed eye scans on NASA astronaut Terry Virts for an astronaut vision study known as Ocular Health which tests microgravity-induced visual impairment, as well as changes believed to arise from elevated intracranial pressure, to characterize how living in microgravity can affect the visual, vascular and central nervous systems. The investigation also measures how long it takes for crew members to return to normal after they return to Earth.

Station Orbit Boosted Sunday Night; Eye Science on Monday

Progress 58 Docking
iss042e274677 (02/17/2015) – The Russian Progress 58 cargo craft pictured shortly before docking to the aft end of the Zvezda service module on the International Space Station.

A reboost of the International Space Station using the Russian Progress 58 cargo craft was completed successfully on Sunday at 7:30 p.m. CDT. A previous attempt on Friday evening was aborted one second into the burn automatically by the Progress vehicle. Russian flight controllers identified an issue with one of the eight thrusters on the spacecraft that was disabled for Sunday’s backup attempt.

The burn lasted 32 minutes and 3 seconds and began the process of setting up the correct phasing for the early June landing of three members of the Expedition 43 crew while providing the proper trajectory for Thursday’s return of the SpaceX Dragon cargo craft for its parachute-assisted landing in the Pacific. The reboost raised the station’s altitude by 1.2 statute miles at apogee and 3 miles at perigee and left the station in an orbit of 252.2 x 247.1 statute miles.

The six-member Expedition 43 crew started its work week with medical science. The crew practiced using a tonometer on an eye simulator with help from doctors on the ground. Similarly, One-Year crew member Scott Kelly explored how microgravity shifts fluids to the upper body impacting a crew member’s vision and eye structure.

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.

The six-member crew also worked a variety of onboard maintenance ensuring crew safety and the upkeep of station hardware. One-Year crew member Scott Kelly worked on science gear in Japan’s Kibo lab module. Commander Terry Virts worked on replacing a Carbon Dioxide Removal Assembly blower fan. Italian astronaut Samantha Cristoforetti routed cables and configured valves to prepare the Permanent Multipurpose Module for its relocation later this month.

On the Russian side of the orbital lab, Flight Engineer Anton Shkaplerov photographed the condition of the Zvezda service module windows. Flight Engineer Gennady Padalka partnered up with One-Year crew member Mikhail Kornienko to study acoustic techniques for immediately locating micrometeoroid impacts on the station’s exterior. The trio also continued the maintenance of the Russian station systems.

The return to Earth for NASA’s Terry Virts, ESA (European Space Agency) astronaut Samantha Cristoforetti and Russian cosmonaut Anton Shkaplerov now is scheduled for early June. NASA and its international partners set the schedule after hearing the Russian Federal Space Agency’s (Roscosmos) findings on the loss of the Progress 59 cargo craft. The exact date has not yet been established and will be announced in the coming weeks.

The crew was scheduled for a half-duty day today to catch their breath following a week of heavy maintenance and in advance of activities to come.

NASA astronauts Terry Virts and Scott Kelly completed the work they’ve been doing this week on one of the station’s Carbon Dioxide Removal Assemblies (CDRA) by reconnecting power, data and fluid lines to the unit. Ground controllers then performed a series of checkouts before the unit was powered back on. The CDRA system works to remove carbon dioxide from the cabin air, allowing for an environmentally safe crew cabin.

ESA astronaut Samantha Cristoforetti focused on a mix of experiment work including the Skin-B study and completing her runs with the Triplelux-A experiment. Skin-B is seeking to better understand the process of skin aging, which is greatly accelerated in microgravity, which could provide insight into the aging process of similar bodily tissues. Triplelux-A is investigating immune suppression in space.
