Orbital Sciences Corporation this week secured a $56.3 million firm-fixed price launch services contract to deliver the Ionospheric Connection Explorer (ICON) […]

NASA Awards Orbital Sciences Launch Services Contract for Hurricane-Forecasting CYGNSS Mission

The CYGNSS mission is comprised of eight Low-Earth Orbiting (LEO) spacecraft (S/C) that receive both direct (white lines) and reflected (blue lines) signals from GPS satellites. The direct signals pinpoint LEO S/C positions, while the reflected signals respond to ocean surface roughness, from which wind speed is retrieved. GPS bi-static scatterometry measures ocean surface […]

Orbital Sciences Corp. is ready to boost its 42nd Pegasus air-launched rocket aloft on […]

NASA Selects Explorer Investigations for 2017 Launch

Investigators believe that the TESS mission, which earlier failed to be accepted for further study in 2009, has a 98-percent probability of finding potentially-habitable transiting exoplanets, orbiting red dwarfs within 50 parsecs of Earth. Image Credit: European Southern Observatory

NASA’s Astrophysics Explorer Program has selected two missions to be launched in 2017. The Transiting […]
