The WorldView-3 satellite launched from Vandenberg AFB on an Atlas V rocket:

What’s WorldView-3, you ask?  Well, if you use Google Earth then you’ve seen imagery from WorldView-2.  WorldView-3 will provide higher spatial resolution imagery, 30 cm vs 50 cm, as well as imagery in additional spectral bands which can support science missions.  From Ball Aerospace, who built the satellite:

WorldView-3 also features the first atmospheric sounder DigitalGlobe will fly in space. The Ball-built Cloud, Aerosol, Water Vapor, Ice, Snow (CAVIS) atmospheric instrument will enable WorldView-3 to collect scientific data based on ground reflection by correcting images for atmospheric interference.

The specs are pretty amazing.  And some propaganda promotional materials from DigitalGlobe here.   (Note the not-so-subtle smackdown of Skybox.)  Like I wrote above, it’s pretty amazing.   Unlike Landsat, you won’t be able to get the imagery for free but, hey, you get what you pay for;-)  Landsat data is good for it’s intended purpose but I think it’ll be really easy to get spoiled on WV-3 imagery.

ADDENDUM:  Most of us think about the visible spectrum – red, green, blue.  If you’d like to learn about what longer wavelengths (too red for the human eye to see) are good for there’s a nice not-to-technical summary here.
