CYGNSS Launch December 15, 2016

Orbital ATK’s Pegasus XL rocket will be dropped from a modified jumbo jet on Thursday, December 15, 2016 to power into orbit with eight mini-satellites that set out to peer into the inside of Hurricanes and reveal hidden mechanisms of storm intensification.

Firing three solid-fueled rocket stages, Pegasus will deliver the CYGNSS satellites into a 500-Kilometer orbit in a mission of less than 15 minutes.

CYGNSS – the Cyclone Global Navigation Satellite System – aims to measure winds over the world’s oceans by measuring GPS signals reflected off the ocean surface. This measurement can penetrate the dense rain bands surrounding the inside of hurricanes, obstructing the view of storm dynamics for conventional sensors.

Gemínidas en directo desde el Observatorio del Teide



Retransmisión en directo de la lluvia de estrellas de las Gemínidas 2016 desde el Observatorio del Teide (Tenerife, Canarias). Esta es la lluvia de estrellas fugaces (meteoros) más importante del año, debido a su alta actividad, rondando los 120 met/hora en tasas zenitales. Todos los trazos parecen proceder de un mismo punto en el cielo, ubicado en la constelación de Géminis (de ahí su nombre). De forma casi excepcional, el cuerpo progenitor de esta lluvia no es un cometa, sino un asteroide, llamado Phaeton, al que los investigadores Jewitt & Li consiguieron verle la cola.

A Look at the U.S. Cold Snap from NASA Infrared Imagery

This animation of AIRS imagery from NASA’s Aqua satellite from Dec. 1 to 11 shows the movement of cold air over the U.S. Cooler temperatures appear in darker blue and warmer temperatures in dark orange.

On Dec. 7, cold Arctic air descended into the Plains states and reached Colorado, Kansas and Missouri. That cold air shifted east on Dec. 9 into the Ohio Valley and New England. Credit: NASA JPL, Ed Olsen
