NASA astronaut Terry Virts, Anton Shkaplerov of the Russian Federal Space Agency (Roscosmos) and Samantha Cristoforetti of the European Space Agency joined their Expedition 42 crewmates when the hatches between the Soyuz TMA-15M spacecraft and the International Space Station officially opened at midnight EST. Expedition 42 Commander Barry “Butch” Wilmore of NASA and Alexander Samoukutyaev and Elena Serova of Roscosmos welcomed the new crew members aboard their orbital home.

Expedition 42 will continue to take advantage of the orbital lab’s unique microgravity environment and expand the scope of research.

The crew will perform experiments that cover human research, biological and physical sciences, technology development and Earth observations as well as engage in educational activities.

They are scheduled to greet a host of cargo vehicles during their mission, including a number of U.S. commercial resupply flights, two Russian Progress resupply missions and the departure of the final European ATV cargo spacecraft. The crew will conduct up to three U.S. spacewalks.

Wilmore, Samoukutyaev and Serova will return home in March 2015. At that time Virts will become commander for Expedition 43. Virts, Shkaplerov and Cristoforetti will return to Earth in May 2015.

The six-person Expedition 41 crew of the International Space Station tackled a range of biomedical research and cargo transfers Friday, capping off a week that included the second of two U.S. spacewalks and preparations for a Russian spacewalk on Oct. 22.

For Flight Engineers Reid Wiseman of NASA and Alexander Gerst of the European Space Agency, most of the day’s science activity focused on a pair of protein crystal growth experiments, which utilize the station’s microgravity environment to grow protein crystals too fragile to form in Earth’s gravity.

Gerst used a reflective microscope to capture images of samples from the NanoRacks-Protein Crystal Growth-1 study, which uses commercial off-the shelf equipment to grow protein crystals on slides.

Later, Gerst joined Wiseman to deactivate and pack up the completed Commercial Protein Crystal Growth-HM experiment.

This investigation is expanding on an ongoing program into the complex realm of membrane proteins that help cells identify each other for immune responses and move molecules to and from a cell’s interior.

Pure crystals that yield information about the protein’s structure will open the way for a coherent, structure-based design of a broader range of medicines for treating diseases and disorders.

The Commercial Protein Crystal Growth-HM experiment, along with about 3,800 pounds of other cargo, is slated to return to Earth on Tuesday aboard the SpaceX Dragon cargo craft.

After the robotics team at Houston’s Mission Control Center uses the Canadarm2 robotic arm to detach Dragon from the Earth-facing port of the Harmony node, Wiseman, with assistance from Flight Engineer Barry Wilmore, will oversee the release of Dragon for its parachute-assisted splashdown off the coast of California.

Two NASA astronauts working outside the International Space Station raced against the clock during a spacewalk today (Oct. 15).

NASA's Reid Wiseman and Barry "Butch" Wilmore performed a 6.5-hour-long spacewalk that included one particularly tricky task that had to be started and completed when the orbiting outpost was in orbital night.

Wilmore and Wiseman managed to remove and replace a power regulator that shorted out in May during the short amount of time when the station experienced night.

"Whoop!" one of the astronauts exulted after the replacement regulator was installed. The regulator, which is used to regulate power from one of the station's solar arrays, needed to be changed out in order to restore the station to full power.

Mission controllers watched a clock ticking down the time the astronauts had to complete the task.

The spacewalk officially began at 8:16 a.m. EDT (1216 GMT) and ended 6 hours and 34 minutes later.

The two astronauts also removed a faulty camera from the outside of the station and installed a new one.

Wilmore and Wiseman also moved some equipment to get ready for the eventual relocation of the station's Permanent Multipurpose Module (PMM) in 2015, NASA officials said.

PMM was built by the Italian Space Agency and is attached to the Earth-facing side of Unity module.

Despite their hard day of work, the astronauts still had time to do a little sightseeing while outside the space station.

They both got some good views of Earth during the spacewalk.

"That is amazing," one of the astronauts said when the spacewalkers spotted a possibly erupting volcano while flying above Earth.

"I see Cairo," Wiseman said during a pass over Egypt. "Can't quite make out the pyramids, though."

The PMM needs to be moved in order to make way for a pair of commercial crewed vehicles that could begin flying astronauts to the orbiting outpost as early as in 2017.

Astronauts will also need to install a set of international docking adaptors that should fly to the station in 2015 for the commercial vehicles.

The two October spacewalks kick off a series of EVAs (extravehicular activities) designed to make way for the new private spaceships once they start delivering astronauts to the station.

"We're going to be doing the things we need to do on these EVAs to prep for moving some modules around," Kenny Todd, space station integration operations manager, said during a news conference before the spacewalks.

"All that is in preparation for being able to support future [commercial] crewed vehicles coming to [the] station. We're trying to get out in front of that … We'll be prepping for moving modules; we'll be installing a new docking adapter system. All of that will be happening throughout the next several months on board the station."

With the first planned excursion of Expedition 41 just a week away, the International Space Station’s six-person crew spent Tuesday preparing spacewalking tools and equipment, while managing a packed agenda of scientific research and maintenance.

Commander Max Suraev of the Russian Federal Space Agency and the team of five flight engineers began the day at 2 a.m. EDT, and after some time for morning hygiene, breakfast and an inspection of the station, they conducted a daily planning conference with the flight control teams around the world.

Afterward, NASA astronauts Reid Wiseman and Barry Wilmore and European Space Agency astronaut Alexander Gerst went to work in the equipment lock section of the Quest airlock to stage the equipment they’ll need in order to prepare for spacewalks set for Oct. 7 and 15.

During the first six-and-a-half-hour spacewalk, slated to begin on Oct. 7 around 8:10 a.m., Wiseman and Gerst will transfer a previously uninstalled pump module from its temporary stowage location to the External Stowage Platform-2.

The two spacewalkers also will install the Mobile Transporter Relay Assembly (MTRA) that adds the capability to provide “keep-alive” power to the system that moves the station’s robotic arm between worksites.

The two astronauts will venture out on the station’s starboard truss to replace a voltage regulator that failed in mid-May.

Although the station has since operated normally on seven of its eight power channels, replacement of the regulator, known as a sequential shunt unit, is considered a high priority.

The International Space Station’s Expedition 41 crew, which doubled the number of humans in space when three new crew members arrived last week, began its first full work week schedule as a six-person crew Monday with biological research and preparations for a pair of U.S. spacewalks.

Alex Samokutyaev

Flight Engineers Barry Wilmore, Alexander Samokutyaev and Elena Serova joined their Expedition 41 crewmates on the station early Friday following a six-hour, four-orbit trek aboard their Soyuz TMA-14M spacecraft from the launch site at the Baikonur Cosmodrome in Kazakhstan.

Wilmore, Samokutyaev and Serova are slated to spend 5 ½ months aboard the station.

Max Suraev

Commander Max Suraev and Flight Engineers Reid Wiseman and Alexander Gerst, who arrived on May 28, will return to Earth in November.

Shortly after the usual 2 a.m. EDT reveille, the entire crew conducted body mass measurements, inspected their orbital home and participated in a daily planning conference with the flight control teams around the world to review the day’s activities.

Yelena Serova

For Wiseman, Gerst and Wilmore, most of those activities were centered primarily on gearing up for their upcoming spacewalks.

During an Oct. 7 excursion outside the station, Wiseman and Gerst will transfer a previously uninstalled pump module from its temporary stowage location to the External Stowage Platform-2.

The two spacewalkers also will install the Mobile Transporter Relay Assembly (MTRA) that adds the capability to provide “keep-alive” power to the Mobile Servicing System (MSS) when the Mobile Transporter is moving between worksites.

Wiseman and Gerst spent some time reviewing the procedures for that spacewalk and later participated in a conference call with spacewalk specialists on the ground.

Wilmore meanwhile began “scrubbing” the cooling loops of the U.S. spacesuits, including the Liquid Cooling and Ventilation Garment that he will wear under his own spacesuit when he joins Wiseman for the second Expedition 41 spacewalk on Oct. 15.

Wiseman completed the spacesuit water recharge in the afternoon and Gerst checked in on the Zebrafish Muscle study.

He assessed the water condition inside the Aquatic Habitat, which is housing a school of spacefaring fish popularly known in the aquarium trade as Zebra Danios.

Space Station to welcome 1st Female Russian Crewmember This Month

A Russian cosmonaut is poised to make a bit of history this when she launches to the International Space Station this month, even if she considers the mission a routine spaceflight.

When cosmonaut Elena Serova launches to the station on Sept. 25 with two other crew mates, she will become the International Space Station's first-ever female Russian crew member and only the fourth female cosmonaut to reach space.

She'll also be the first female Russian cosmonaut to fly in the 17 years since cosmonaut Yelena Kondakova's STS-84 space shuttle mission in May 1997 but Serova, 38, said she doesn't see her mission any differently than that of a male cosmonaut.

"I wouldn't say I am doing more ... than what my colleagues are doing," she said in translated remarks during a preflight briefing at NASA's Johnson Space Center in Houston in July.

Serova pointed out that women have gone into space before, and that her focus is on fulfilling her assigned duties as a flight engineer.

"I want to perform my job really well," she said.

In 1963, Russia (then part of the Soviet Union) was the first nation to fly a woman in space, sending Valentina Tereshkova aloft in June of that year on a mission that lasted nearly three days in Earth orbit.

Svetlana Savitskaya was the second Soviet female cosmonaut, making two flights into space in 1982 and 1984 and staying aboard the Salyut 7 space station.

She also was the first female to peform a spacewalk.

The United States didn't send its first woman to space until 1983, when Sally Ride blasted off.

Dozens of women from the United States and other nations have flown since, but only one other from Russia: Kondakova.

She made two trips to the Mir space station, in 1994 (on a Soyuz capsule) and 1997 (on a space shuttle).

Serova has said she's been fascinated by space since childhood, and that she always felt visiting the final frontier was possible.

"The door to space was opened to all women by Valentina Tereshkova," she said in a NASA interview.
