ACEIZE Tracking the current state of Science and Technology

As Discovery undocked from the International Space Station, they took a picture of the station with a backdrop of planet earth. Discovery had just finished eight days docked at the station. They had switched out crew members, installed new solar panels, and re-stocked supplies.

The solar panels which were extended this week returned symmetry to the space station's solar power array. Astronaut Michael Fincke remarked that this symmetry was 'not to be underestimated'. I'm not sure what that means.
