Landsat The Landsat series of Earth-observing satellites has been in orbit since 1972. On February 11, the next generation of Landsat satellites is set to launch what NASA is calling the Landsat Data Continuity Mission. Check out LIMA – the Landsat Image Mosaic of Antarctica – here.

Stargazing our own spiral arm Deborah Byrd explains what we’re looking at when we look up into the evening sky in Northern Hemisphere winter, and why the stars look so brilliant at this time of year. See charts of stars in our local Orion Arm of the galaxy here.
