Pegasus Rocket Prepared for NASA’s ICON Mission

Orbital ATK’s Pegasus XL rocket is being prepared to launch NASA’s Ionospheric Connection Explorer, or ICON mission. The rocket is being prepared in a facility at Vandenberg Air Force Base (VAFB) in California.
The rocket’s second and third stages, first stage motor and wing arrived at VAFB and were transported to Building 1555 for processing.
ICON will launch aboard Pegasus from the Kwajalein Atoll, part of the Republic of the Marshall Islands in the Pacific Ocean, on Dec. 9, 2017 (in the continental United States the launch date is Dec.8 ).
ICON will study the frontier of space — the dynamic zone high in Earth’s atmosphere wh ere terrestrial weather from below meets space weather above. The explorer will help determine the physics of Earth’s space environment and pave the way for mitigating its effects on our technology, communications systems and society.

Explorer: ICON (MIDEX 8 )

ICON (MIDEX 8 ) [OSC]

ICON (Ionospheric Connection) will explore the boundary between Earth and space – the ionosphere – to understand the physical connection between our world and the immediate space environment around us. This region, where ionized plasma and neutral gas collide and react exhibits dramatic variability that affects space-based technological systems like GPS.
Though the solar inputs are now well quantified, the drivers of ionospheric variability originating from lower atmospheric regions are not. ICON is the first space mission to simultaneously retrieve all of the properties of the system that both influence and result from the dynamical and chemical coupling of the atmosphere and ionosphere. ICON achieves this through an innovative measurement technique that combines remote optical imaging and in situ measurements of the plasma. With this approach, ICON gives us the ability to (1) separate the drivers and pinpoint the real cause of ionospheric variability (2) explain how energy and momentum from the lower atmosphere propagate into the space environment, and (3) explain how these drivers set the stage for the extreme conditions of solar-driven magnetic storms. ICON’s imaging capability combined with its in-situ measurements on the same spacecraft (Figure 1) gives a perspective of the coupled system that would otherwise require two or more orbiting observatories.
ICON targets the low-latitude ionosphere because recent global-scale observations of this region show remarkable spatial and temporal variability that contravene the conventional view of ion-neutral coupling in space, and evince strong forcing by lower atmosphere drivers. The coupling of the atmosphere to space is strongest at these latitudes because the atmospheric waves are largest and so is the density of the space plasma, produced in abundance by the sun overhead and confined by the magnetic field.
Following instruments are on boards:
  • MIGHTI (Michelson Interferometer for Global High-Resolution Thermospheric Imaging): Remotely measuring the neutral wind field and temperatures – Heritage from SHIMMER flown on STPSat-1.
  • EUV (Extreme Ultra-Violet): Measuring the height and density of the daytime ionosphere – Heritage from SPEAR flown on the Korean STSAT-1.
  • FUV (Far Ultra-Violet): Measuring the daytime atmospheric composition and the ionosphere at night – Heritage from FUV flown on IMAGE.
  • IVM (Ion Velocity Meter): Measuring the electric fields detected at the satellite – Heritage from IVM flown on C/NOFS CINDI.

Orbital was selected to provide a LEOStar-2 based bus.
ICON will launch by 2017 into a low earth orbit, operating for at least two years. A Pegasus-XL launch vehicle was selected in November 2013 for a launch in 2017.

NASA’s ICON Explores the Boundary Between Earth and Space

On Dec. 8, 2017, NASA launches the Ionospheric Connection Explorer, or ICON, a low-Earth orbiting satellite that will give us new information about how Earth’s atmosphere interacts with near-Earth space — a give-and-take that plays a major role in the safety of our satellites and reliability of communications signals.

Mission Update Nov. 3, 2017 - NASA is postponing launch of the Ionospheric Connection Explorer (ICON) until 2018. The mission was previously planned to launch Dec. 8, 2017, on an Orbital ATK Pegasus XL rocket from the Reagan Test Site on Kwajalein Atoll in the Marshall Islands. NASA and Orbital ATK need additional time to assess a separation component of the rocket. More information on a revised launch date will be provided once it becomes available.

Launch of NASA ionospheric probe delayed to examine rocket issue

The launch of a NASA satellite to study the behavior of plasma in Earth’s ionosphere has been delayed to early next year, giving engineers time to resolve concerns with the separation system on its air-launched Pegasus XL booster.

NASA’s Ionospheric Connection Explorer was set for launch Dec. 8, but the mission is not expected to take off until at least early 2018 after managers ordered a delay, NASA announced Nov. 3.

Two Heads Are Better than One: ICON & GOLD Teaming Up To Explore Earth’s Interface to Space

Like Earth, space has weather. Except instead of swirling winds and downpours of precipitation, space weather is defined by shifting electric and magnetic fields and rains of charged particles. At the very beginning of space, starting just 60 miles above Earth’s surface, there’s a layer of the atmosphere that shifts and changes in concert with both types of weather.

Posted May 2, 2018 at 2:49 pm




On May 1, 2018, NASA’s Ionospheric Connection Explorer, or ICON, arrived at Vandenberg Air Force Base in California for the next stage of its journey to launch, scheduled for June 14 fr om Kwajalein Atoll in the Marshall Islands.

The observatory made the trip overnight fr om Gilbert, Arizona, wh ere it was in an Orbital ATK facility. At Vandenberg, ICON will be integrated onto a Pegasus XL rocket, which will in turn be flown to Kwajalein on an L-1011 aircraft, which will double as its launcher.

A solar array illumination test is performed on NASA’s Ionospheric Connection Explorer, or ICON, satellite in the Building 1555 clean room Friday, May 4, 2018, at Vandenberg Air Force Base in California. The test checks for any imperfections and confirms that the solar arrays are functioning properly.

ICON arrived on May 1, 2018, and preflight processing began after it was offloaded and transported to its current location. The explorer will launch June 15, 2018, fr om Kwajalein Atoll in the Marshall Islands (June 14 in the continental United States). The satellite will be carried aloft on Orbital ATK’s Pegasus XL rocket, attached to the company’s L-1011 Stargazer aircraft.

ICON will study the frontier of space — the dynamic zone high in Earth’s atmosphere wh ere terrestrial weather from below meets space weather above. The explorer will help determine the physics of Earth’s space environment and pave the way for mitigating its effects on technology, communications systems and society.

NASA Previews Mission to Study Frontier of Space


Processes in Earth’s ionosphere create bright swaths of color in the sky, known as airglow, as seen here in an image taken from the International Space Station. NASA’s Ionospheric Connection (ICON) mission will track airglow to observe how interactions between Earth's weather and the ionosphere create changes in our space environment.

NASA will host a media briefing at 1 p.m. EDT Monday, June 4, on the agency’s mission to explore Earth’s ionosphere and the processes there that impact life on Earth’s surface. The event will air live on NASA Television, the agency’s website and Facebook Live.
