We've worked closely with GeoEye throughout the afternoon to make their most recent satellite imagery of Haiti, taken at approximately 10:27am EST today, available as a KML overlay for Google Earth. You can download the KML here and open it in Google Earth, or look at it via the browser plug-in below. As you'll see, the imagery shows a powerful glimpse into the destruction in Haiti. Here are before-and-after screenshots of the Presidential Palace and an area of Port-au-Prince:

We will continue to automatically update the layer (you'll only need to download it once) as we are able to make more imagery and data available.
