Thank you to those that were able to join the webinars today. If you were unable to attend, you can check out the recording of the webinar, presentation, and movie HERE! This will be a great campaign and I look forward to working with all of you. Remember, if you have any questions, please contact me Brian.A.Campbell@nasa.gov The campaign officially starts on October 1, 2015 and runs until...


GLOBE Friends, Greetings from NASA and the SMAP satellite mission! As you know, The GLOBE Program has a collaboration with the NASA Soil Moisture Active Passive (SMAP) satellite mission. As part of this collaboration, we have developed the SMAP Block Pattern Soil Moisture Protocol, that allows for the collection of volumetric soil moisture measurements, just like the measurements we get from...


Mission managers for NASA's Soil Moisture Active Passive (SMAP) observatory have determined that its radar, one of the satellite's two science instruments, can no longer return data. However, the mission, which was launched in January to map global soil moisture and detect whether soils are frozen or thawed, continues to produce high-quality science measurements supporting SMAP's objectives...


SMAPpers,   The GLOBE/SMAP Soil Moisture Measurement Campaign is almost here! Beginning October 1, 2015 and ending April 30, 2016, we are hoping to get a wide array of GLOBE schools participating.   NASA launched an Earth observing satellite called Soil Moisture Active Passive (SMAP) on January 31, 2015 and its purpose is to measure soil moisture globally with a high level of...


Mission managers at NASA's Jet Propulsion Laboratory, Pasadena, California, are assessing an anomaly with the radar instrument on NASA's Soil Moisture Active Passive (SMAP) satellite observatory. The radar is one of two science instruments on SMAP used to map global soil moisture and detect whether soils are frozen or thawed. See more HERE!


The radar measurements made by NASA's Soil Moisture Active Passive (SMAP) observatory are sensitive to whether land surfaces are frozen or thawed. As liquid water freezes in soil, the water molecules become bound in a crystalline lattice, which changes how the incoming radar energy from SMAP interacts with Earth's surface, compared to soil containing freely oriented liquid water molecules. ...


"With its antenna now spinning at full speed, NASA's new Soil Moisture Active Passive (SMAP) observatory has successfully re-tested its science instruments and generated its first global maps, a key step to beginning routine science operations next month." Read more HERE! Brian


So, now that we have a satellite in space called SMAP, why is the data from the spacecraft so important? SMAP will help: Monitor Drought Predict Floods Assist Crop Productivity Improve Weather Forecasting Linking Water, Energy, and Carbon Cycles Read more HERE


To find our where the SMAP spacecraft is, at any time in relation to my school, you can check on the SMAP Orbit Calculator Tool! As you might have noticed in the SMAP Block Pattern Soil Moisture Protocol document, we recommend that measurements be taken and collected around 9:00am local time.  This is due to the SMAP spacecraft's 6am and 6pm local time equator crossings.  In order to...


Hi Everyone, This past week and a half has been rather quiet as we performed two orbital maneuvers. The first maneuver placed the spacecraft at an altitude closer to its final orbit. The second one slightly adjusted the inclination of the orbit to ensure that SMAP goes over the equator at approximately 6:00 am and 6:00 pm every day, which are the ideal times to obtain our science...


As you know, SMAP will be giving us unprecedented soil moisture data from around the Earth. But, did you know that SMAP is also looking at frozen soil?  Check out the article link below to learn more about this measurement and how it aligns to our better understanding of our ecosystem and climate change.

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),...


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...


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...


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,...


Hi Everyone, A lot has happened since my last posting. The mission operations team has been hard at work testing the spacecraft and learning its intricacies. Having a new satellite in space is like driving a new car, it takes a little while to learn how it behaves and reacts. This past week we’ve been testing subsystems and making sure that temperatures and voltages are within range. Also,...


WOW, WOW, WOW! Early Saturday morning, January 31, 2015, everything was a GO for the SMAP launch except the high altitude winds were too strong to proceed. Everyone was on edge and ten minutes before the scheduled launch time things turned for the better. The wind situation was deemed “green” and it was safe to continue. Whew! The launch itself was an exhilarating experience. As the countdown...


The SMAP team would like to give a shout out to the schools in Trinidad and Tobago, Croatia, and Oman that have already started taking measurements with the SMAP Block Pattern Soil Moisture Protocol. We are excited to compare GLOBE student data to the SMAP spacecraft data, once the spacecraft starts taking soil moisture. The SMAP spacecraft is currently working on the phase when we raise the...


Hi Everyone, The Thursday before the launch of SMAP was a day of much anticipation and excitement. We were ready to go, but high upper winds caused the cancellation of the launch four minutes before lift-off.  You might be wondering how we monitor wind conditions at high altitudes (in this case, thirty four thousand feet). We do it by sending up weather balloons ahead of time to make...


Hi Everyone, My name is Erika Podest, and I am a scientist at JPL working on the SMAP mission. I’ll be writing about SMAP’s debut into space and providing updates during this exciting time. Welcome to my first post! As a child growing up in tropical Panama and enjoying its exuberant nature, I always had a love for the environment. I went from playing in nature to studying it, and focused my...
