Twin STEREO Observatories Poised for Launch
Twin STEREO Observatories Poised for Launch

With two days remaining until launch, STEREO is safely encapsulated inside the protective payload fairing at the top of the Boeing Delta II rocket. The vehicle's second stage will be loaded with storable propellants today.

The launch weather forecast is favorable, with virtually no concerns. A strong front is moving through the area later today, and high pressure behind it will result in favorable weather for Tuesday and Wednesday. There is a 5% chance of weather violating launch constraints, due to possible development of cumulus clouds.

The two-year STEREO mission is the first to take measurements of the sun and solar wind in 3-dimension. This new view will improve our understanding of space weather and its impact on the Earth.
