[by Lina Tran on the NASA blog] On June 22, NASA’s ICON team released scientific data collected during the spacecraft’s first eight months in orbit to the public.

The data release features observations from ICON’s four instruments — MIGHTI, FUV, EUV, and IVM — which have been observing the ins and outs of the ionosphere, the sea of charged particles high in the upper atmosphere. Scientists have been busy parsing the wealth of observations collected by ICON in preparation for the mission’s first science results, which will be released later this year.

“ICON was designed, built, and launched to provide data we had never seen before, and it has not disappointed us in any regard,” said Thomas Immel, ICON principal investigator at University of California, Berkeley. Immel said he was pleased to share ICON’s first data with the world. “The sensitivity and precision of our observations, and the unique orbit and mission design, give us a new and advanced tool for unlocking all the puzzling questions we have had about the connection between Earth’s atmosphere and our space environment.”

The release coincides with the virtual summer meeting of CEDAR, the Coupling, Energetics, and Dynamics of Atmospheric Regions program. The newly released data spans measurements made since the mission’s launch on Oct. 10, 2019. Data can be accessed through University of California Berkeley’s Space Sciences Lab.

The CEDAR 2020 annual face-to-face conference has been cancelled due to COVID-19, but a two-day virtual conference will take place June 22-26. It will include a National Science Foundation town hall, student workshop, pre-recorded presentations and individual workshops.

ICON results will be featured in its own data introduction and tutorial session and in several more of these workshops, including those focused on Thermospheric Winds, Model Systems Engineering and Coordinated Ground and Space-Based observations.   

The agenda for the CEDAR meeting is here.

Just over six weeks after launch and early calibrations, NASA’s Ionospheric Connection Explorer (ICON) mission was presented with a unique opportunity. ICON flew very close to the December 26 solar eclipse track that extended across Asia, and observed the major changes in upper atmospheric airglow that naturally occurred. ICON’s four instruments, primed to look at the ionosphere, the dynamic region where Earth meets space, were in position to observe the effects. What happens when airglow –the natural glow of Earth’s atmosphere caused by solar radiation – is temporarily “turned off” when the sun is blocked by the moon’s shadow for a few minutes? Preliminary data shows that all four instruments – MIGHTI, EUV, FUV and IVM – were able to see changes the eclipse wrought.

On January 7, 2020, ICON first light images were featured as NASA Earth Observatory's "Image of the Day," in an article called "ICONic Views of the Ionosphere."
