The most common location for the installation of solar panels is rooftop. It is often the most practical location, as well as the most economical.

Economical, common, and practical are not words that describe the location of NASA’s latest installation of an array of solar panels. We’ve done some unorthodox installations during our years of construction, but we’ve NEVER done a spacewalk to install a solar panel array!

(Hey NASA, if you ever need additional help installing solar panels on the space station, we’re more than happy to help – pro bono!)

This morning, beginning at 8:30am EST, NASA will be broadcasting live the 7 hour spacewalk to add more solar panels to the International Space Station.

From nasa.gov:

“NASA astronauts aboard the International Space Station will conduct a spacewalk on Thursday, Dec. 22, to install a rollout solar array to increase electrical power in support of operations and scientific research. The spacewalk is scheduled to begin at 8:30 a.m. EST and last about seven hours.

The agency will provide live coverage of the spacewalk beginning at 7 a.m. on NASA Television, the app, and the agency’s website.

Expedition 68 Flight Engineers Frank Rubio and Josh Cassada will exit the station’s Quest airlock to install an International Space Station Roll-Out Solar Array (iROSA) to augment power generation for the 4A power channel on the station’s port truss.”
