For all you Earth observation geeks out there, we have some good news — two Russian astronauts are going to install a camera on Friday (Dec. 27) that will beam live images of Earth back to your browser.
The UrtheCast camera is the headline task for Expedition 38 astronauts Oleg Kotov and Sergey Ryazanskiy to perform, on top of installing a foot restraint and doing some equipment swapouts. This spacewalk, by the way, is not related in any way to the two successful contingency ones earlier this week to replace a faulty pump on station.
The spacewalk is supposed to start at 8 a.m. EST (1 p.m. UTC) and will be carried live on NASA Television, which you can view in the media player above or at this alternate link. The spacewalk is scheduled for seven hours, but could be longer or shorter as events arise.

“Imagine you have a nearly live Google Earth, but it isn’t four-year-old data – you have data that is being refreshed all the time, with videos coming down over interesting areas where interesting events are going on, showing you what is changing, what is going on,” said George Tyc, the chief technology officer at UrtheCast, in an interview with Universe Today earlier this year.
“What we really hope to pull off is to change the paradigm, get the everyday person interacting and seeing the data coming down from space to see the Earth and how it is evolving over time in a way that isn’t available right now.”

It’s been a busy week for spacewalkers on station as Rick Mastracchio and Mike Hopkins successfully replaced a pump that shut down two weeks ago and crippled one of the station’s two cooling loops for regulating the temperature of systems on station. With that work completed Tuesday (Dec. 24), a NASA update today (Dec. 26) said systems are slowly coming back online.
“Early on Christmas Day, the heat exchangers for the Destiny laboratory, the Harmony and Tranquility nodes and the Japanese Kibo laboratory were reintegrated to enable experiments racks and other systems affected by the partial Cooling Loop A shutdown Dec. 11 to come back on line,” NASA stated.
“The Columbus laboratory heat exchanger will remain down until the European Space Agency, at its own request, conducts that module’s integration next week when personnel return from the holiday.”
