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...

Last Friday, February 27th, was the one-year anniversary of the launch of the Global Precipitation Measurement Mission Core Observatory, and coinciding with that event, released its first global map of rainfall and snowfall, covering the period from April 2014 to September 2014. The data map combines measurements from 12 satellites and the GPM Core Observatory, which serves to unify the data from all the satellites, like the lead violin in an orchestra tuning the rest of the instruments.  The result is NASA's Integrated Multi-satellite Retrievals for GPM data product, called IMERG,...

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, we have transitioned the spacecraft to point directly at the ground (nadir). While not everything has behaved as expected, the team has addressed some minor yet unexpected issues quickly and is...

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 reached the final two seconds there was a sudden boom, followed by a bright yellow/orange glow and a white cloud that mushroomed to the sides of the rocket. SMAP soared into the sky much faster...

I was born and raised in Michigan’s Upper Peninsula.  If you’re unfamiliar with this extreme northern region of Michigan, it is meteorologically famous for its snow.  Lots of snow.  Insane amounts of snow.  Sled-from-your rooftop piles of snow (see below image). Driving a car in this winter wonderland is difficult since pavement is merely a rumor on most streets from November through April.   While snow provides many anxious driving moments, it is also cherished for creating breathtaking winter landscapes and for providing a wide variety of winter outdoor...

Chances are that if you are reading this blog you are interested in bringing the exciting world of satellites and remote sensing into your classroom. Over the past five decades NASA and NOAA have archived satellite imagery and datasets and there is high interest in educators using these resources from both agencies. However, the challenge to the precollege community over the years has been one of both acquiring the technical skills to retrieve such imagery and data, and having the computer power to acquire and store such large files. The good news is that while aerospace engineers and...

We're just over two weeks in to the campaign, and I wanted to give a shout out to those schools who have so far entered data. Some of them are entering data from multiple sites at their school to have so many data points in two weeks. Keep up the good work, and more updates coming soon!

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 antenna boom and unfurl the collecting dish. Thank you and keep the soil moisture data coming! Brian
