Johnson Space Center Reopens
6 August 2008 10:45 a.m. EDT

NASA's Johnson Space Center (JSC) in Houston has re-opened after being closed for a day and a half due to tropical storm Edouard.

Despite the storm, which hit the coast of Texas early Tuesday, the mission control center at Johnson remained open, continuing to oversee operations aboard the International Space Station in orbit.

NASA has not reported any damage to the space center from the storm.

Mission Control Remains Open Despite Tropical Storm
4 August 2008 12:35 p.m. EDT

Though NASA's Johnson Space Center (JSC) in Houston is closing today and tomorrow because of tropical storm Edouard's expected impact, mission control will stay open, NASA spokesman Kyle Herring said.

The storm is predicted to hit land somewhere in Texas or southwest Louisiana Tuesday morning. While most of JSC is evacuating as a precaution, NASA has decided critical mission control staff can stay put for now to support operations aboard the orbiting International Space Station (ISS).

"Our main concern is the safety of the flight control teams," Herring told SPACE.com. "If it were a much larger, more powerful storm we could relocate the oversight from here to a different location."

So far, NASA doesn't predict the storm will impact any missions, including the ISS or upcoming space shuttle flights.

Success as Cosmonauts Return Home
15 July 2008 7:07 p.m. EDT

The spacewalkers have both reentered the Pirs docking compartment and closed the hatch at 7:02 p.m. EDT (2302 GMT).

Volkov and Kononenko checked each other’s suits carefully for any signs of damage or contamination before going into the hatch one after the other. They first took some time to rearrange some equipment tethered in and around the hatch.

The cosmonauts joked with Russian mission control about extending the five hour, fifty four minute spacewalk to six hours. Mission controllers conveyed thanks for the completion of the assigned tasks and the impromptu fix of the radio antenna, and remarked upon the July 10 spacewalk as well.

“Even the first attempt was perfect,” Russian mission control told the cosmonauts. “Everything was done professionally.”

Spacewalkers Hit Final Stretch
15 July 2008 6:42 p.m. EDT

The two cosmonauts returned to the vicinity of the airlock to complete their final task by retrieving the Biorisk experiment.

Kononenko moved to the experiment location and began removing the Biorisk containers, while Volkov retrieved a foot restraint from where it had been temporarily stowed.

Russian mission control warned the cosmonauts to “be very careful around the Soyuz antenna,” as the two spacewalkers worked near the Soyuz spacecraft docked to the space station.

Any worries proved unfounded, as Kononenko returned the Biorisk containers to the airlock. Both cosmonauts are now preparing to enter the hatch.

The spacewalk has reached its estimated time length of five and a half hours.

Cosmonaut Straightens Out Ham Radio Antenna
15 July 2008 6:11 p.m. EDT

The Russian spacewalkers have one scheduled task left, but Volkov took the opportunity to fix a ham radio antenna that had been disabled.

Russian mission control guided Volkov to the antenna location, where the space station commander straightened out the ham antenna and fitted it back into its vertical slot.

“Please let me go home,” Volkov joked. “I guess we’ve done it all for today?”

He and Kononenko will now turn to the final task of retrieving the Biorisk experiment’s payload, which was installed on Expedition 15 last summer. That experiment studies the effects of space radiation and zero G on microorganisms.

Volkov’s path to the radio antenna actually passed the work site, but neither he nor Russian mission control realized that fact until the cosmonaut had already returned.

Burst Experiment Comes Alive
15 July 2008 5:49 p.m. EDT

Volkov and Kononenko forged ahead with installing the Burst experiment by cutting a wire that was holding them up, and routing the final clamp through the tangle of cables.

“Take a break,” Russian mission control told Kononenko. “You can talk to Sergei [Volkov].”

The cosmonauts took some time to relax and gaze upon the Earth for a bit.

“The thunderstorms look beautiful,” one cosmonaut said.

They finally received word that the Burst experiment had started functioning.

“We have telemetry,” said Russian mission control. “Vsplesk is alive.”

The cosmonauts are now removing protective covers from the radiators, before jettisoning them.

Spacewalkers Tie Down Science Experiment
15 July 2008 5:24 p.m. EDT

The two spacewalkers secured the “Burst” experiment on the Russian segment of the space station with hand-turned clamps and wire ties.

Volkov and Kononenko are now tying tethers to hand rails in order to support the experiment, working through a mess of cables as they match each tether to the appropriate spots. They are also tightening clamps and attaching connectors.

“Are we still making it, Sergei?” Kononenko asked at one point, checking on the schedule. They have one connector left.

Spacewalkers Start Installing Physics Experiment
15 July 2008 4:43 p.m. EDT

The spacewalkers have reached the location where they will install a new science experiment on the Russian service module of the space station.

The Vsplesk or “Burst” experiment is designed to measure the effects of high energy particle streams and cosmic bursts. Volkov and Kononenko used a handrail to move along the side of the module and reach the target area.

A camera caught a view of some debris spinning away from the space station. Mission controllers are trying to determine whether it might be paint from the handrails.

Cosmonauts Stow Foot Restraint, Crane
15 July 2008 4:24 p.m. EDT

Kononenko has returned to the main space station body, and the cosmonauts are now relocating the foot restraint from the Strela crane.

The spacewalk has passed the three hour mark and remained ahead of schedule for the most part. However, a delay occurred when Volkov and Kononenko ran into trouble with one of the tethers while securing the Strela crane.

The cosmonauts dealt with the tether and temporarily relocated the foot restraint, so they can now look forward to installing a new high-energy physics experiment called “Burst” on the Russian segment of the space station.

Finishing the Photo Shoot
15 July 2008 3:43 p.m. EDT

The two spacewalkers ran into some difficulty getting Kononenko in place to take pictures of the space station, but should remain on schedule barring further delays.

“I am in position, but there is no way to stop rotation,” Kononenko said, as he tried to keep himself steady on the end of the Strela crane and focus his camera. The cosmonaut gamely snapped images even as he and Volkov tried to negotiate the best solutions with Russian mission control in Moscow.

Photography finally wrapped up, allowing Volkov to begin retracting the 50-foot Strela boom and bring Kononenko back to the main body of the space station.

The cosmonauts will go on to reposition the foot restraint on the end of the crane. However, Russian mission control first wanted Kononenko to get a few additional shots.

“Yes, take pictures of yourself,” a mission controller said. “We love it.”

Going Out on a Crane
15 July 2008 3:18 p.m. EDT

The spacewalk is moving slightly ahead of schedule as the cosmonauts make their way to the next work site.

Kononenko has attached himself to the end of one of two Strela hand-powered cranes, as Volkov is slowly maneuvering him past one of the space station’s solar arrays. Kononenko has begun taking images for inspection as he struggles to position himself.

“Please embrace the Strela boom with your legs,” someone advised.

“I don’t even feel the button,” Kononenko said, trying to get the camera in place.

Pausing to Take a Picture
15 July 2008 2:45 p.m. EDT

The spacewalkers are taking pictures of the installed docking target before moving on to the removal and repositioning of a foot restraint attached to Strela crane.

“When you’re taking photographs, do not hurry,” Volkov instructed fellow spacewalker Kononenko, and added that the camera still had 200 shots. “Take photographs to your heart’s content.”

Cosmonauts Float on Past Two Tasks
15 July 2008 2:32 p.m. EDT

The spacewalkers are performing an inspection of the mounting holes that will be used for the future installation of an antenna adapter, as part of the Kurs automated docking system.

A brief discussion occurred about whether to trim away part of the space station’s insulation to gain better access to the work area.

Volkov and Kononenko also talked about watching the film White Sun of the Desert, a traditional viewing for cosmonauts before launch and one of the most popular Russian films.

The cosmonauts are now packing up, after a brief scare where a tool appeared to fly away before getting caught.

“Nothing can escape from us,” one cosmonaut joked.

Docking Target in Place
15 July 2008 2:10 p.m. EDT

The cosmonauts have reached the first work site and installed the docking target on the zenith, or space-ward, side of the Russian Zvezda module.

The work required the spacewalkers to lift up flaps and insert an adapter into mounting holes that hold the docking target. Volkov wielded a camera to take pictures of the installation process, but both cosmonauts appeared eager to get on with the spacewalk.

“Ok, we’re not going to waste too much time on that, Oleg,” Volkov said, after taking several pictures.

Kononenko held Volkov in place as the latter maneuvered a bit to get the docking target in place. The cosmonauts are now moving on to their next task.

Spacewalkers Commuting to Work Site
15 July 2008 1:50 p.m. EDT

Volkov (red stripes) and Kononenko (blue stripes) are organizing their tools and preparing for the docking target installation outside the space station.

Kononenko is again sporting a helmet camera adapted from U.S. spacesuits, so that mission controllers can better see the ongoing work. The cosmonauts are floating alongside one another as they work, unhooking and hooking their tethers as they move along.

One cosmonaut noted a difference between the handrail area outside the Russian module and the simulator they had worked with.

Cosmonauts Step Out
15 July 2008 1:30 p.m. EDT

Both Russian cosmonauts have exited the Pirs docking compartment to prepare for the first task of installing a docking target on the Zvezda module of the International Space Station.

Kononenko exited first and received the adapter and docking target from Volkov inside the airlock. Kononenko then made his way to the Strela hand-powered crane, which will take him to the work site on the Russian module.

Volkov has also just exited the airlock to prepare for his role in operating the crane.

Russians Celebrate Successful Spacewalk
10 July 2008 9:10 p.m. EDT

The first-time spacewalkers have successfully completed the first of two jaunts outside the space station.

Volkov and Kononenko secured the Strela hand-crane to the Pirs docking compartment before going back into the space station and closing the hatch. They were outside for 6 hours, 18 minutes.

Russian mission controllers congratulated Volkov on becoming a “full crew commander” after getting handed the “grenade,” or pyro bolt.

The cosmonauts will bring the pyro bolt back to Earth with them on October 23, riding the current Soyuz.

Spacewalk Almost Sewn Up
10 July 2008 8:03 p.m. EDT

The cosmonauts have finished playing space tailor as they used wire ties and tethers to secure the thermal blanket.

Volkov and Kononenko have also jettisoned the covers that they used to protect the Soyuz thrusters from possible contamination during the spacewalk, when loose pieces of insulation may have floated off as Kononenko cut it away with the serrated knife.

Mission controllers are instructing the cosmonauts on how to use the Strela hand-crane to move back to the safety of the International Space Station.

Cosmonauts Succeed in Removing Explosive Bolt
10 July 2008 6:48 p.m. EDT

The crowning moment of the spacewalk arrived as Volkov used a socket wrench to unscrew the explosive pyro bolt from its housing.

Kononenko stood by with the blast-proof case to secure the bolt, while Russian mission control asked the cosmonauts to count the number of turns with the socket wrench. An estimated 10 turns was needed to remove the bolt.

 “After five, please be very careful,” said a Russian mission controller.

The cosmonauts paused at eight turns as they conferred on their plan of action, and then cooperated to loosen the bolt and put it into its secure case.

“Good! Thank God, it is in” exclaimed one cosmonaut. The major objective was completed at 3 hours and 58 minutes into the spacewalk.

Russian mission control dictated a five minute break “without any motions, without moving.”

Spacewalkers Exchange Places to Continue Work
10 July 2008 6:26 p.m. EDT

Space station commander Sergei Volkov exchanged places with flight engineer Oleg Kononenko as they prepared the pyro bolt for removal.

The cosmonauts are using various tools to disconnect the electrical connector from the pyro bolts. The Soyuz spacecraft has five sections with two pyro bolts each fire to separate the instrument and return modules.

A locking ring that holds the pyro bolts in place has proved stubborn. Russian mission controllers instructed the cosmonauts to try and tear the ring off by force, while also trying to ensure that they did not tire.

“Oleg, please let Sergei do it because you need a rest,” a Russian mission controller said, repeating his request several times.

One of the covers protecting the Soyuz thrusters had popped off earlier and was dangling from its tether. Russian mission control has asked the spacewalkers to put it back on.

Cosmonauts Apply “Dino Cutters”
10 July 2008 5:52 p.m. EDT

The spacewalkers have begun preparing the work area to remove one of the ten explosive bolts that Russian engineers suspect as a cause for the Soyuz spacecraft malfunctions.

Kononenko is applying a set of pliers called “dino cutters” that will ground any static electricity from the area. That step helps prepare for eventually disconnecting the explosive bolts on the Soyuz from the electrical connector.

Kononenko and Volkov continue to work in fairly tight quarters, despite removing much of the insulation covering the area.

Spacewalkers Use Knife to Cut Away Insulation
10 July 2008 5:16 p.m. EDT

Kononenko has used a serrated knife to cut away all necessary insulation from the Soyuz spacecraft work site.

“We feel sorry for the vehicle.” Konenko joked.

“We’re not damaging it, we’re healing it,” fellow spacewalker Volkov replied. He has now reached the spacecraft to work alongside Kononenko.

The cosmonauts worked to remove a locking ring and reach the pyro bolt that represents the goal of this spacewalk.

Ten pyro bolts fire to separate the Soyuz modules and prepare the spacecraft for reentry. Russian engineers suspect that a faulty bolt may be behind recent malfunctions that caused the two latest Soyuz missions to undergo ballistic reentry.

Volkov and Russian mission control kept careful watch on Kononenko’s work with the knife.

“Oleg, be more careful with the cutter,” Volkov warned. “I’m concerned about your gloves.”

Cosmonauts Begin Work
10 July 2008 4:55 p.m. EDT

The first spacewalker has reached the work site on the Soyuz spacecraft, and has begun examining the area for any possible signs of damage.

“I don’t see anything expensive or criminal.” Kononenko said after glancing at the location between the Soyuz instrument module and descent module.

After Volkov maneuvered Kononenko closer to the site by using the hand crane, the latter began taking photographs despite some trouble with sunlight reflecting in the viewer.

Volkov has also begun making his way up the Strela hand crane toward the work site, while his crewmate started placing protective covers over the thrusters between the Soyuz modules.

Spacewalk Underway Again
10 July 2008 4:38 p.m. EDT

Spacewalker Kononenko is now on his way to the work site on the Soyuz spacecraft.

Kononenko encountered earlier difficulties getting into a foot restraint, which is designed to allow him to ride the 50-foot boom of the Strela crane to the work site.

Russian mission control finally instructed the cosmonaut to improvise and tether himself to the crane. Fellow spacewalker Volkov operated the hand-powered crane to move Kononenko.

The third member of the space station crew, U.S. astronaut and flight engineer Greg Chamitoff, is sitting inside the Soyuz spacecraft for the duration of the six-hour spacewalk in case of an emergency.

“We can probably go ahead and scare Greg a little through the window,” one cosmonaut joked.

Spacewalk Held Up By Foot Restraint Problems
10 July 2008 4:20 p.m. EDT

Volkov issued a stream of instructions to fellow spacewalker Kononenko, who is encountering difficulty getting into a foot restraint.

Kononenko will use the foot restraint to ride a 50-foot hand-powered crane up to the main work site on the Soyuz spacecraft.

 “Strange, I had it,” Kononenko said as he struggled to get his feet planted in the foot restraint. The cosmonaut cannot get both his feet into the foot restraint.

“Guys, let’s take a minute break,” a Russian mission controller interjected at one point.

Near one hour and thirty minutes into the spacewalk, everyone was eager to get on with the work at hand.

“We’re running short of time,” the mission controller said, suggesting a workaround solution.

Spacewalkers Get Started
10 July 2008 2:48 p.m. EDT

Flight engineer Oleg Kononenko has opened the hatch of the International Space Station, which marks the official start of today’s nearly six-hour spacewalk at 2:48 EDT.

This is the 113th spacewalk in support of space station maintenance and the first spacewalk for both cosmonauts. Volkov becomes the first second-generation spacewalker, following his father Alexander Volkov who spent time on both the Russian Salyut 7 station and the Mir Space Station.

Russian mission controllers first talked the cosmonauts through depressurizing the Piers spacewalk compartment through which they exited. Volkov and Kononenko also tested their helmet lights, with Kononenko sporting a wireless camera normally worn on U.S. spacesuits.

The two cosmonauts pure-breathed oxygen during depressurization to clear out nitrogen from their blood and prevent the condition known as the bends.
