RUBBER CHICKEN FLIES INTO SOLAR STORM: In a unusual twist on space science, students [2] in California have launched a rubber chicken to the edge of space to study a solar storm. Get the full story [3] from Science@NASA [4].

 

UNUSUAL 3D METEOR PHOTO-OP: This weekend, NASA scientists, amateur astronomers, and an astronaut on board the International Space Station will attempt the first-ever 3D photography of meteors from Earth and space. The rare photo-op occurs during the peak of the Lyrid meteor shower on Saturday night, April 21st. [full story [5]] [meteor radar [6]] [Lyrid video [7]]

 

INCOMING PLASMA CLOUDS: On April 18th and 19th, a series of minor CMEs puffed away from the sun. Three of them are heading in our general direction. Analysts at the Goddard Space Weather Lab have prepared an animated forecast track of the ensemble:
