The Space Sciences Lab had the great pleasure of hosting this fantastic group of social media bloggers all day on June 13 for a "NASA Social" featuring ICON. A NASA Social event is an informal meeting of people who engage with NASA social media accounts. After applying for media credentials and being vetted by NASA, they have the opportunity to go behind-the-scenes at NASA facilities and events and speak with scientists, engineers, technicians and managers, and they tweet and post to their respective social media along the way. Our closest NASA Social visitor came from San Jose UC Berkeley and the farthest from Colombia, South America; a YouTuber came from Montreal. Their day at SSL began with talks and close interaction with the ICON team and the ICON life-size payload model. The afternoon included a special tour of mission operations and an opportunity to get close to the 11-meter satellite dish during a data pass.

NASA and Northrop Grumman have postponed ICON's launch. During a ferry transit, Northrop Grumman saw off-nominal data from the Pegasus rocket. While ICON remains healthy, the mission will return to Vandenberg Air Force Base in California for rocket testing and data analysis.A new launch date will be determined at a later date.

If scientists hope to predict the magnetic storms around Earth that endanger satellites and interfere with radio communications on the ground, they must understand how tropical storms on Earth affect these magnetic storms 60 miles above our heads.

A new mission, NASA’s Ionospheric Connection Explorer (ICON), is charged with that very task: to measure the winds of ionized atoms at the edge of space and determine how they are impacted by atmospheric weather, in particular seasonal monsoons in the tropics.

In preparation for launch, the ICON EUV instrument recently went through a week long "scrub" activity at the Orbital ATK facility in Gilbert, Arizona. The detector in EUV is a microchannel plate (MCP), and the millions of tiny tubes in the MCP can develop different characteristics during all the testing done on the ground, and overall become less effective. The scrub involves running the detector at high voltage while it is illuminated by a bright EUV light source, which cleans off any molecules that weren’t there at the start of all that testing. When done for a sufficient amount of time (a week, in this case), the detector develops a more uniform and stable amplification, just like when it was new. It’s like a drink from the fountain of youth for the MCP.
