The COSMO-SkyMed 3 satellite will be launched into orbit tomorrow, October 24, at 19:28:21, or 21 seconds after 7:28pm, Pacific time, from Vandenberg AFB in California. Says here that the rocket will be a Delta II, which puts on a great show. While the launch will be spectacular from nearby viewing locations, it will be visible all over the southwest U.S. and northwest Mexico. More from that last link:
|COSMO-SkyMed, one of the most innovative Earth Observation programmes, is financed by the Ministry for Education, Universities and Scientific Research, the Italian Space Agency (ASI) and the Ministry of Defence.|
|The programme involves the launch of a constellation of four satellites, equipped with radar sensors that can operate under any weather conditions and with very short revisiting times.|
|COSMO-SkyMed was conceived as a dual use programme intended to meet both civil and defence objectives. The application services that can be derived from COSMO-SkyMed will contribute significantly to the defence of the territory in areas such as fire, landslides, droughts, floods, pollution, earthquakes and subsidence, management of natural resources in agriculture and forestry, as well as monitoring of urban sprawl.|
Guess this is the third in the series.
In any case, I assume that this one has a polar orbit, which is the only kind of orbit that allows scanning of the whole earth over the course of time. That means it will be launching toward the south. This is good. Even if it’s in that direction, it will still be impressive.
Here’s a photoset of two launches from Vandenberg AFB, and two launches there, both shot from Santa Barbara. And here’s a video of one of those.
One cool thing: As the rocket enters space, exhaust is no longer contained by atmosphere, and it expands into something shaped like an elongated light bulb. Then the exhaust drifts in strange and wandering ways, determined by edge-of-space movements in atmosphere, altered by the directions of rocket exhaust, and then space itself, where the exhaust moves win all the directions the rockets shoot (which in most cases is in four directions at once). It’s fun and strange to watch.
I’m in Boston now, so we’ll miss it here; but if you’re anywhere southwest of Utah, enjoy.
Hat tip to the SBAU for the heads-up.
