earth orbit

Preparations for launching NASA's Gamma-ray Large Area Telescope satellite are underway at NASA's Kennedy Space Center, Fla.

NASA KSC's "NASA Expendable Launch Vehicle Status Report" on Thursday, March 20, noted that GLAST's twin solar panels have been attached.

The panels will provide electrical power for GLAST after its launch into earth orbit.

Radio waves accelerate electrons within Jupiter's magnetic field in the same way as they do on Earth, according to new research published in Nature Physics this week.

The discovery overturns a theory that has held sway for more than a generation and has important implications for protecting Earth-orbiting satellites.
