ULA Delivers Four-Spacecraft Flotilla on Magnetospheric Multiscale Mission

United Launch Alliance (ULA) has successfully flown its highly reliable Atlas V booster out of Cape Canaveral Air Force Station, Fla., to deliver the four-spacecraft flotilla of NASA’s Magnetospheric Multiscale Mission (MMS) into a Highly Elliptical Orbit (HEO) to explore the microphysics of “magnetic reconnection,” a process which converts magnetic energy into heat and […]

Landing Region Chosen for InSight at T-Minus One Year to Red Planet Launch

In the weeks after NASA’s InSight mission reaches Mars in September 2016, the lander’s arm will lift two science instruments off the deck and place them onto the ground. This image shows testing of InSight’s robotic arm at JPL about two years before it will perform these tasks on Mars. Credit: NASA/JPL-Caltech

At T-minus […]
