GPM Undergoes Electromagnetic Testing

The GPM Core Observatory is continuing with the environmental test program at NASA Goddard Space Flight Center. Following the completion of thermal vacuum testing in January 2013, the Core Observatory team started the Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) test phase. The Core Observatory has successfully completed the Radio Frequency (RF) Self-Compatibility test and is being prepared for the next step of EMI/EMC test program. The EMI/EMC test program is expected to be completed in April 2013.

2013 PMM Science Team Meeting

The NASA Precipitation Measurement Missions (PMM) Science Team for the TRMM and GPM missions met on March 18-21, 2013 in Annapolis, MD. This meeting included oral, poster, and evening working group sessions covering mission/program status, algorithm development activities, international partner reports, science activities, field campaign results, and other science team business. More than 175 scientists from 11 countries participated. The TRMM satellite is now in its 16th year of on-orbit operation and the GPM Core Observatory is scheduled to launch in early 2014.

Tropical Cyclone Sandra Nearing New Caledonia

Tropical cyclone Sandra formed in the Coral Sea south off the Solomon Islands on March 7, 2013. Sandra intensified over the open waters of the Coral Sea and became a very powerful tropical cyclone with winds of about 110 kts (~127 mph). Sandra has started weakening but is predicted to buffet northern New Caledonia with tropical storm force winds on March 12, 2013. Sandra's approximate past and forecast locations are shown overlaid in white. The TRMM satellite passed above Sandra on March 10, 2013 at 2219 UTC.

Tropical Cyclone Sandra Brushing New Caledonia

On March 11, 2013 the TRMM satellite twice flew above weakening tropical cyclone Sandra as it was passing to the west of New Caledonia in the southern Pacific Ocean. TRMM's Precipitation Radar (PR) had a very good view of Sandra as it passed directly above the tropical cyclone on March 11, 2013 at 1312 UTC. TRMM PR measured rainfall at the extreme rate of over 206 mm/hr (~8 inches) in an area southwest of Sandra's eye. Those TRMM PR data also showed that very little rain was occurring north of the weakening tropical cyclone's eye. Click here to see a simulated Flyby over Sandra using 3-D TRMM

"The photo was taken in Hungary, near a little village called Sződliget"

How this Photo Was Taken:
"It was one of those chilly mornings when the sky was clear and the wind was calm. You could hear the small branches break as a bird flew near. The surface of the lake was smooth and covered with thin ice. Everything was white and not a sound heard, just some faint sough trough the rimed tree branches. Like if everything would have been frozen. Time itself."

"(not exactly a cool story but) - Hiking a few kilometers through the snow, was worth it for this view."
