Hey All, We just finished up a two-day GLOBE Train-the-Trainer Workshop at the GEMS World Academy in Chicago, Illinois. Trainers from across the USA came to learn about several NASA Earth Science Missions and their affiliation with GLOBE and associated protocols.  Those missions are Cloud Satellite (Cloudsat), Global Precipitation Measurement (GPM), Soil Moisture Active Passive (SMAP), and Landsat. On the SMAP side of things, we had a bit of a tough time digging out soil samples for the SMAP Block Pattern Soil Moisture Protocol due to snow/ice cover and partially frozen soil*. ...

Hi Everyone, This past week has been smooth sailing as we tested both of our instruments, the radar and the radiometer. The radar’s high power transmitter was turned on as the spacecraft was flying over the North Atlantic and then over Greenland. The telemetry data looked great and the signals received clearly showed the transition from ocean to land (yay!). There were some biases with the data that still need to be worked out, however everything is working and we will have a better sense of the quality of the radar data once the antenna starts spinning. During this past week we also...

Fresh off the recent successful deployment of its 20-foot (6-meter) reflector antenna and associated boom arm, NASA's new Soil Moisture Active Passive (SMAP) observatory has successfully completed a two-day test of its science instruments. The observatory's radar and radiometer instruments were successfully operated for the first time with SMAP's antenna in a non-spinning mode on Feb. 27 and 28. The test was a key step in preparation for the planned spin-up of SMAP's antenna to approximately 15 revolutions per minute in late March. The spin-up will be performed in a two-step process...

WOW! If you are not amazed by this GPM Data Visualization loop, you should be! ( www.youtube.com/embed/ILNC7IdyWVU?enablejsapi=1&rel=0 ) Earth SySTEM is an approach to STEM Education that utilizes the current and future technological infrastructure of satellite imagery, remote sensing, and computer visualizations, and data archives in the study of Earth as a System .   So the question becomes, besides being pretty pictures, what else can students do with these types of satellite images, remote sensing and computer visualizations? There are many...

Hi Everyone, The major milestone this past week was the deployment of the reflector antenna/boom assembly (RBA), which refers to a 5-meter (~16 foot) long boom that holds a 6-meter (~20 foot) diameter antenna at the end of it. For launch the RBA was folded against the spacecraft to fit within the launch vehicle fairing. The boom and antenna together weigh 58 kilograms (127 pounds). Yes, super light for something that size. The boom is a carbon composite structure, made of multiple layers of carbon fiber cloth that are impregnated with a special resin, then baked to create a...
