Laser printers provide excellent print output on paper in both black and white and full color. Laser printers use a fairly complicated printing process that techs should understand. This episode details the processes and components for...

Every full moon, Landsat 8 turns its back on Earth. As the satellite's orbit takes it to the nighttime side of the planet, Landsat 8 pivots to point at the moon. It scans the distant lunar surface multiple times, then flips back...

On November 19, Operation IceBridge flew a successful 10.9 hour mission to the Pine Island region of Antarctica. All instruments collected data along previous ICESat and CryoSat satellite tracks in an effort to calibrate and validate...
