T minus 4 and counting!

The official launch count has resumed...four minutes to go!

Oxygen is still venting in a long stream from the center of the rocket...

T minus 3...

Third stage is being armed...

I just heard "Go Phoenix!" over the NASA commentary...not a cheer, it's part of the countdown...

Two minutes to launch...no more oxygen venting...

90 seconds...

80 seconds...

Range is "go" for launch...nothing in the way...

70 seconds...

Puffs of oxygen venting...they're topping off...

35 seconds...

T minus 20...
