Social media group spends a day at SSL for ICON "NASA Social"

Karin Hauck 0 208

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.

Launch of NASA’s ICON Satellite Postponed

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.

June 14 launch of ICON satellite to probe the edge of space

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.


Designed and built at the Space Sciences Laboratory of UC Berkeley, ICON is scheduled for a June 14 launch from an airplane over the Pacific Ocean, and should start probing the upper atmosphere and ionosphere by August.

“We are built to catch everything that is coming up into space at the boundary of space,” said Thomas Immel, principle investigator for the mission and a physicist at the Space Sciences Laboratory. “Anything that comes past there we are going to see.”

ICON arrives at Vandenberg

On May 1, our Ionospheric Connection Explorer arrived at Vandenberg Air Force Base in California for the next stage of its journey to launch, which is scheduled for June 14 US time from Kwajalein Atoll in the Marshall Islands. (Kwajalein is in a different time zone so it will be June 15 there.)

The observatory made an overnight trip from Gilbert, Arizona, where it was in an Orbital ATK facility. At Vandenberg, ICON will be integrated onto a Pegasus XL rocket and flown to Kwajalein on an L-1011 aircraft, which will double as the rocket's launcher.

Rub-A-Dub-Dub, ICON EUV gets a scrub

Karin Hauck 0 211

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.
