The second Italian COSMO-SkyMed mission was launched on a Delta-II booster at 6:31 PM PST on Saturday, December 8, 2007. In order to place it in the same orbital plane as the first COSMOS-Skymed satellite, the launch window was only one second long. The launch had been scrubbed due to upper level winds two minutes before launch on Wednesday. Lower level winds prevented a launch attempt on Friday. Turbulent weather conditions put the launch on Saturday in jeapardy.

Delta II/COSMO-SkyMed Satellite Launch, December 8, 2007 The Delta-II ascended through some cloud decks shortly after launch. I used two cameras to capture the launch from ignition through burnout of the first stage. The two cameras shot sequences of thirty-second long exposures that were stacked to produce this composite image.

Delta II/COSMO-SkyMed Satellite Launch, December 8, 2007 The arching trajectory of the Delta-II carried it through the constellations Aquila and Capricorn. The first stage burned out near the constellation Grus.

Delta II/COSMO-SkyMed Satellite Launch, December 8, 2007 This composite of four frames shows the burnout of the first stage, four minutes and 36 seconds after launch, and the beginning of the burn of the second stage five seconds later. The second stage engine is much smaller and burns with a dimmer flame than the first stage. The three frames below show the same part of the sky.

Delta II/COSMO-SkyMed Satellite Launch, December 8, 2007 This exposure caught the first thirty seconds of the second stage burn. It has been processed to make the rocket more visible.

Delta II/COSMO-SkyMed Satellite Launch, December 8, 2007 This exposure caught the second thirty seconds of the second stage burn. There is a hint of a cloud where the second stage ignited. The upper stage of the Delta-II exited the frame before the end of the exposure. The second stage burned for six minutes and fifty seconds.
