'You just saved the video dish': Two astronauts complete spacewalk to replace ISS antenna

Two astronauts in white spacesuits work near a large antenna dish outside a space station with a blue and white planet as their backdrop.

"Houston, we have a working comm link again."

Thanks to the efforts of two astronauts, such a call is possible again using one of two Space-to-Ground antennas outside the International Space Station (ISS). The pair finished the replacement of a faulty dish assembly during a spacewalk on Tuesday (Aug. 25).
