It's been a damp day here at Kennedy Space Center. As you may have seen on Twitter, we're here to witness the final launch of Atlantis--the last hurrah for the Space Shuttle.

The rain has been on and off all afternoon, but the drizzle did not stop us from heading out to the pad for a final farewell to Atlantis before launch, which as of this writing is still scheduled for 11:26 AM EST tomorrow.

Despite the wetness, optimism remains. At 5:45 p.m. EST, the engineering review board meeting concluded with the decision to continue the countdown. The meeting also dispelled a moment of brief concern when a lightning storm crossed the launch pad at around noon today. Two strikes were recorded in the pad's vicinity, but the shuttle and its launch support equipment were unharmed.
