In a view through a porthole, cosmonauts Oleg Kotov and Sergey Ryazanskiy can be seen working to mount a high-resolution camera to a mounting platform on the International Space Station's Zvezda command module.
running into problems hooking up two commercial Earth-viewing cameras,
cosmonauts Oleg Kotov and Sergey Ryazanskiy reluctantly brought the high-tech cameras back into the Pirs airlock module&Friday, closed the hatch and ended a marathon spacewalk, setting a new Russian

you for all your hard work, and we're so sorry that it turned out this
way," a flight controller radioed in translated remarks.
spacewalk began at&8
a.m.&and ended at&4:07 p.m. EST&(GMT-5). The eight-hour seven-minute outing set a new
Russian endurance record and beat the previous mark of seven-hours and 29
minutes set in August by cosmonauts Fyodor Yurchikhin and Alexander Misurkin.
The U.S. spacewalk record stands at eight hours and 56 minutes.
primary objective of Friday's outing was to install , a high-resolution telescope mounted on an aiming
platform and a fixed medium-resolution camera. Both are required for a
long-awaited commercial project to beam down near realtime high-definition
Earth views, including a free internet stream as well as focused observations
for paying customers.
and Ryazanskiy successfully installed the cameras and plugged them into the
station's power and data circuits. But Russian flight controllers did not
receive telemetry, prompting the cosmonauts to retrace their steps and inspect
each electrical connector.
cosmonauts reported no obvious problems, unplugging and reconnecting the cables
between the cameras and two "patch panels" on the hull of the Zvezda
command module. But the troubleshooting did not work.Kotov and Ryazanskiy were asked to take additional photographs of the cameras on their mounts, along with visible electrical connectors, before detaching them and hauling them back into the Pirs airlock compartment."So
it appears we have seen an unsuccessful attempt at bringing those two cameras
to life,"said Rob Navias, NASA's mission control commentator. "The exact cause of the problem is not known at
this point. The Russian flight control team will spend some time, obviously,
analyzing the data and trying to understand from the analysis of these
photographs whether or not the problem lies in the electrical connectors
themselves or in the cameras, which of course would be a more significant
long it might take to resolve the camera issue and stage another spacewalk to
install them is not yet known.
Business reported earlier this year that UrtheCast had secured a $35 million
insurance policy "for the launch, installation, commissioning and business
interruption of its two cameras aboard the ISS." If the cameras failed to
work properly or could not be installed, the report said, the company would use
the insurance coverage to build and launch a fresh set of cameras.
Today's spacewalk was the third in less than a week. It followed&.&This was the 177th spacewalk devoted to station assembly and maintenance since construction began in 1998, the eleventh and final EVA for the year, the fifth for Kotov and the second for Ryazanskiy.One hundred and 14 astronauts and cosmonauts representing nine nations have now logged 1,115 hours and 44 minutes of spacewalk time outside the International Space Station, or 46.5 days.

Advisers are weighing strategies in light of the IRS' recent announcement on its treatment of after-tax money in 401(k) plans, but those opportunities might be hard to come by at the employer level.Last week, the Internal Revenue Service released guidance in Notice 2014-54, indicating it would allow savers to break out the after-tax portion of money they've contributed to a retirement plan and convert it to a Roth IRA free of taxes.
