The launch of the reusable X-37B spacecraft has now been slipped to Nov. 27

Equipped with a 35-meter dish antenna and super-cold, low-noise amplifiers

Isolated thermal control system radiator, rerouted flow of ammonia coolant

ALL GROWN UP: The U.S. Air Force’s second Advanced Extremely High Frequency (AEHF) satellite has completed its on-orbit testing in preparation for transfer for operational use. The satellite, built by Lockheed Martin, was launched in May. In addition to the on-orbit testing of its own systems, it also executed trials to link with AEHF-1.

Carried nearly 5,800 lb. of propellant, water, compressed air and oxygen, spare parts and research gear

Europe’s second Infrared Atmospheric Sounding Interferometer (IASI), considered by some forecasters the best of its kind in the world, has gone into service on Eumetsat’s Metop-B polar-orbiting weather satellite. Developed by France’s Centre National d’Etudes Spatiales (CNES) and Thales Alenia Space, the IASI measures infrared wavelengths across 8,461 different spectral channels to generate high-resolution vertical profiles of the atmosphere’s temperature and humidity. The data is crucial to numerical weather prediction models.

STORM WEATHERED: An Orbital Sciences Corp. Antares rocket stage, on its seaside launch pad at Wallops Island, Va., for an upcoming hot-fire test, “looks to be in pretty good shape” after weathering Hurricane Sandy. Wallops was evacuated for the storm, leaving the Antares first stage in position on the pad and the nearby horizontal processing facility locked down. While the processing facility had already weathered one severe storm, it was the first time for Antares flight hardware. After a quick inspection Oct.

PARIS and NAPLES, Italy — French space agency CNES is studying next-generation launch vehicle concepts for a modular Ariane 6 that would use existing technologies and production facilities to replace the cumbersome, costly and commercially reliant Ariane 5 of today.
