In anticipation of another CERES instrument launched onboard JPSS-1  (now scheduled for 4:47 am EST on November 15), I thought I’d share a little about CERES and why it’s so important to understanding our Earth – and how GLOBE observations fit into this science. NASA’s CERES instrument, which stands for Cloud and the Earth’s Radiant Energy System , measures reflected sunlight and thermal infrared radiation emitted by the Earth.  It measures the amount of energy leaving the Earth so we can compare this to the amount of energy entering the Earth .  You may have...

Just How ‘Cool’ Was The Eclipse? Temperature Data From NASA Langley Anyone who witnessed the total solar eclipse on August 21st, 2017 would agree--it was an awe-inspiring event. The Sun was blotted out by the Moon, a 360° sunset glowed from every direction. Nocturnal animals like crickets began their night-time activities while people went quiet to watch the stars come out in the middle of the day. Even for those not in the path of totality, the extra-sharp shadows cast by the partially eclipsed Sun and the crescent-shaped lights cast through pinhole projectors, interlaced fingers,...

While we wait for SAGE to get turned on, here are high school activities on SAGE to bring out the STEM. After launch on Saturday was aborted, we are excited to share that SAGE did successfully launch to the space station on board a Falcon 9 Rocket on February 19.  You can watch a video of the launch here . So now that it hitched a ride into space, now what?  Well, we have to catch it.  The SAGE instrument is still sitting inside of the SpaceX Dragon spacecraft.  A planned rendezvous to then dock with the International Space Station was planned for today but...

How much ozone is in the stratosphere? What role do aerosols play in the air we breathe? These are some of the questions we are seeking to answer with ongoing SAGE missions. The next SAGE instrument is set to launch to the International Space Station on February 18, 2017. The Stratospheric Aerosol and Gas Experiment, SAGE, is part of NASA’s mission to provide long-term measurements that help humans better understand and protect Earth’s atmosphere. SAGE measures the Earth’s sunscreen, or ozone, along with other gases and aerosols, or tiny particles in the atmosphere. SAGE makes its...
