Satellite images show glowing sea. It’s always interesting when science can help confirm ghost tales. The real question is this… is it really bacteria or the ghosts of souls lost at sea? We may never know…
We here at VerySpatial have received our first honest to goodness press release! What is more, its for an actually useful product. Pixel742 generates distributable GeoTIFFs from Landsat bands 7, 4, & 2 to create a Natural color output. There is a demo but I haven’t plyed with it yet.
Whatever your beliefs on the global warming issue, the recent spate of articles on the melting of Arctic ice and the warming of the climate in Alaska seem pretty scary. Satellite imagery is being used to show that the Arctic ice cap is shrinking at an alarming rate.

If you simply must know where it is day and night around the world, here are a couple of websites for you.
time.gov keeps the official U.S. time via atomic clock and has a feature which shows where the sun is shining and where it is dark when you click on a time zone. Check it out here
The second website, by John Walker (founder of AutoDesk), offers the Earth and Moon Viewer, which has the day and night feature, as well as views of the earth from the moon, and the day and night sides using satellite imagery. It is much more of a webmapping interface, with query boxes to change the view and type of imagery.

The ESA will soon be launching a new satellite to measure the ice levels at the poles to determine if the prediction that global warming is impacting ice levels is true. From the article, the main sensor will be radar.
The European Space Agency has decided to extend the life of the Mars Express Spacecraft which is the platform for the radar sensor that has provided elevation and other information of Mars. For the full story head over to the BBC.
Data is data. Sure Google gives folks a great interface to view it, but aerial and sattelite images have been captured for decades. Archaeologists have found archaeological sites via aeiral photos since the 1960s, Roman Villas and all. Folks aware of remote sensing have been leaving things to be seen in images, for good and bad, for almost as long as RS has been around…ok rant complete. The start of Google Maps Messages?
