A new experiment, scheduled to launch to the International Space Station in the spring, plans to take a long look at vision changes often experienced by astronauts during extended spaceflights, NASA officials announced on Tuesday.

The cause of these vision issues is called visual impairment and intracranial pressure syndrome (VIIP), and according to the US space agency, it involves changes not only in the sense of sight but the structure of the eyes and indirect signs of increases pressure on the brain.

A shift in fluids

The human body is roughly 60 percent fluids, and in space, these fluids shift to the upper part of the body, moving across blood vessels and cell membranes in a different way than they do on Earth. The upcoming Fluid Shifts study will test the relationship between this phenomenon and VIIP, which reportedly affects over half of all US astronauts during extended spaceflights.

Learning more about how blood pressure in the brain affects vision and eye shape could also help those on Earth dealing with conditions that increase swelling and pressure in the eye, as well as though who have been placed on extended periods of bed rest.

Our first aim is to assess the shift in fluids, to see where fluids go and how the shift varies in different individuals, explained Dr. Michael B. Stenger of the Wyle Science Technology and Engineering Group, one of the principal investigators of the Fluid Shifts project.

The second goal, Stenger added, is to correlate fluid movement with changes in vision, the structure of the eye, and other elements of VIIP syndrome. A third objective is to evaluate the application of negative pressure to the lower body, with the intention of preventing or reversing fluid shifts and determining if this can prevent vision changes from occurring.

Three International Space Station crew members are scheduled to leave the orbiting laboratory Wednesday, March 11 after almost six months in space performing scientific research and technology demonstrations.

NASA Television will provide complete coverage of their departure and return to Earth, beginning with the space station change of command ceremony on Tuesday, March 10.

Expedition 42 Commander Barry Wilmore of NASA will hand over command of the station to fellow NASA astronaut Terry Virts. At 6:44 p.m. Wednesday, Wilmore and flight engineers Alexander Samokutyaev and Elena Serova of the Russian Federal Space Agency (Roscosmos) will undock their Soyuz spacecraft from the space station and land in Kazakhstan at 10:08 p.m. (8:08 a.m. March 12 Kazakh time).

NASA Television coverage is as follows:

Tuesday, March 10

10:25 a.m. -- Change of command ceremony in which Wilmore hands over station command to Virts

Wednesday, March 11

3 p.m. -- Farewell and hatch closure coverage (hatch closure scheduled at 3:25 p.m.)

Story highlights Spacewalk last more than five hours; crews have spent more than 1,171 hours spacewalking Astronaut Terry Virts found a small amount of water inside his helmet

In a tweet, the space agency said astronaut Terry Virts experienced water inside his helmet, just as he did Wednesday, but "it's a known issue; no concern."

The spacewalk lasted five hours and 38 minutes, NASA said.

"Crews have now spent a total of 1,171 hours and 29 minutes conducting space station assembly and maintenance during 187 spacewalks," the agency said in a release.

NASA previously said the suit worn by NASA astronaut Virts has a history of "sublimator water carryover." Water in the sublimator cooling component can condense when the suit is repressurized after a spacewalk, causing a small amount of water to push into the helmet, NASA said.

NASA said International Space Station managers had "a high degree of confidence" in the suit.

On the upcoming spacewalk, Virts and Barry Wilmore installed antennas to provide data to visiting vehicles and deploy 400 feet of cable along the edge of the station.

Virts said he first noticed traces of fluid and dampness in his helmet Wednesday while he was waiting for the crew lock cabin to repressurize.
