Sounding Rockets Launch Into an Aurora

The interaction of solar winds and Earth’s atmosphere produces northern lights, or auroras, that dance across the night sky and mesmerize the casual observer. However, to scientists this interaction is more than a light display. It produces many questions about the role it plays in Earth’s meteorological processes and the impact on the planet’s atmosphere. To help answer some of these questions, NASA suborbital sounding rockets carrying university-developed experiments -- the Mesosphere-Lower Thermosphere Turbulence Experiment (M-TeX) and Mesospheric Inversion-layer Stratified Turbulence (MIST) -- were launched into auroras from the Poker Flat Research Range in Alaska. The experiments explore the Earth’s atmosphere’s response to auroral, radiation belt and solar energetic particles and associated effects on nitric oxide and ozone. This composite shot of all four sounding rockets for the M-TeX and MIST experiments is made up of 30 second exposures. The rocket salvo began at 4:13 a.m. EST, Jan. 26, 2015. A fifth rocket carrying the Auroral Spatial Structures Probe remains ready on the launch pad. The launch window for this experiment runs through Jan. 27.

Rocky Mountain National Park Viewed From the International Space Station

Marking the 100th anniversary of the Rocky Mountain National Park on Jan. 26, 2015, Expedition 42 Flight Engineer Terry Virts posted this photograph, taken from the International Space Station, to Twitter. Virts wrote, "Majestic peaks and trails! Happy 100th anniversary @RockyNPS So much beauty to behold in our @NatlParkService." Image Credit: NASA/Terry Virts via NASA

Greenland's Leidy Glacier

Located in the northwest corner of Greenland, Leidy Glacier is fed by ice from the Academy Glacier (upstream and inland). As Leidy approaches the sea, it is diverted around the tip of an island that separates the Olriks Fjord to the south and Academy Cove to the north. The resulting crisscross pattern is simply the result of ice flowing along the path of least resistance. This view of the region pictured above was acquired August 7, 2012, by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. In April 2012, the feature caught the attention of a NASA pilot, who snapped this picture from the cockpit of a high-flying ER-2 aircraft during a research flight over the Greenland ice cap.

In the Vortex of Power

John Wargo, lead technician at NASA Glenn's Propulsion System Laboratory (PSL) is performing an inspection on the inlet ducting, upstream of the Honeywell ALF 502 engine that was recently used for the NASA Engine Icing Validation test. This test allows engine manufacturers to simulate flying through the upper atmosphere where large amounts of icing particles can be ingested and cause flame outs or a loss of engine power on aircraft. This test was the first of its kind in the world and was highly successful in validating PSL's new capability. No other engine test facility has this capability. Glenn is working with industry to address this aviation issue by establishing a capability that will allow engines to be operated at the same temperature and pressure conditions experienced in flight, with ice particles being ingested into full scale engines to simulate flight through a deep convective cloud. The information gained through performing these tests will also be used to establish test methods and techniques for the study of engine icing in new and existing commercial engines, and to develop data required for advanced computer codes that can be specifically applied to assess an engine's susceptibility to icing in terms of its safety, performance and operability.
