NASA Administrator Charles Bolden listens to Magnetospheric Multiscale (MMS) Mission Project Manager Craig Tooley talk about the MMS mission outside of a Naval Research Laboratory cleanroom where one of four Magnetospheric Multiscale (MMS) spacecraft is currently undergoing testing, Monday, August 4, 2014, in Washington. The Magnetospheric Multiscale, or MMS, mission will study the mystery of how magnetic fields around Earth connect and disconnect, explosively releasing energy via a process known as magnetic reconnection. The four identical spacecraft are scheduled to launch in 2015 from Cape Canaveral and will orbit around Earth in varying formations through the dynamic magnetic system surrounding our planet to provide the first three-dimensional views of the magnetic reconnection process. The goal of the STP Program is to understand the fundamental physical processes of the space environment from the sun to Earth, other planets, and the extremes of the solar system boundary. Photo Credit: (NASA/Bill Ingalls)

In late July 2013, a low pressure system off Australia’s southeast coast and moist onshore winds combined to create unsettled weather across central Australia – and a striking image of a broad cloud band across the stark winter landscape.  The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite captured this true-color image on July 22 at 01:05 UTC (10:35 a.m. Australian Central Standard Time). To the west of the low pressure trough the skies are clear and dry. To the east, the broad band of bright white clouds obscures the landscape. The system brought wind, precipitation and cooler temperatures to the region.  The same day as MODIS captured this image, the Naval Research Lab (NRL) published an edition of the Global Storm Tracker (GST), which gave a world-wide view of the low-pressure systems across the world. This tracker shows the entire cloud band across Australia, as well as the location of the low pressure system.  A good view of the Storm Tracker is provided by Red Orbit at: <a href="http://www.redorbit.com/media/uploads/2013/07/072213-weather-003-storm-tracker.jpg" rel="nofollow">www.redorbit.com/media/uploads/2013/07/072213-weather-003...</a>  Credit: NASA/GSFC/Jeff Schmaltz/MODIS Land Rapid Response Team  <b><a href="http://www.nasa.gov/audience/formedia/features/MP_Photo_Guidelines.html" rel="nofollow">NASA image use policy.</a></b>  <b><a href="http://www.nasa.gov/centers/goddard/home/index.html" rel="nofollow">NASA Goddard Space Flight Center</a></b> enables NASA’s mission through four scientific endeavors: Earth Science, Heliophysics, Solar System Exploration, and Astrophysics.

TEMPEST-D — a weather-observing satellite the size of a cereal box — captured imagery of Hurricane Dorian off the coast of Puerto Rico in the early morning hours (local time) of Aug. 28, 2019. At a vantage point 250 miles (400 kilometers) above the storm, the CubeSat used its miniaturized radio-wave-based instrument to see through the clouds, revealing areas with strong rain and moisture being pulled into the storm. The green colors show moisture spiraling into the storm's center, and the yellow to pink colors correspond to the most intense rainfall. TEMPEST-D — short for Temporal Experiment for Storms and Tropical Systems Demonstration — is an experiment in shrinking weather satellites to a size that makes them inexpensive enough to produce in multiples. The goal is eventual real-time storm coverage with many small satellites that can track storms around the world.  https://photojournal.jpl.nasa.gov/catalog/PIA23414

ICON is being prepared for its launch on a Pegasus XL rocket, attached beneath the company's L-1011 Stargazer aircraft. Launch is scheduled for Oct. 10, 2019, from the Skid Strip at Cape Canaveral Air Force Station in Florida. ICON will study the frontier of space - the dynamic zone high in Earth's atmosphere where 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 and communications systems.
Pegasus ICON Solar Array Panel Removal
The Northrop Grumman Pegasus XL vehicle is inside Building 1555 at Vandenberg Air Force Base in California, on Oct. 8, 2018. The payload fairing is installed around NASA's Ionospheric Connection Explorer (ICON). The Pegasus XL, attached to the company's L-1011 Stargazer aircraft, will launch from the Skid Strip at Cape Canaveral Air Force Station in Florida. Launch is scheduled for Oct. 26. ICON will study the frontier of space - the dynamic zone high in Earth's atmosphere where 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.

Technicians secure Northrop Grumman's Pegasus XL rocket, containing NASA's Ionospheric Connection Explorer (ICON), beneath the company's L-1011 Stargazer aircraft at the hot pad at Vandenberg Air Force Base in California, on Oct. 14, 2018. The Stargazer will take off from the hot pad and travel to Cape Canaveral Air Force Station in Florida. The Pegasus XL rocket will launch ICON from the Skid Strip at the Cape. ICON will study the frontier of space - the dynamic zone high in Earth's atmosphere where 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 and communications systems.
Pegasus ICON Rollout to Hotpad, Mate to L-1011
Inside Building 1555 at Vandenberg Air Force Base in California, technicians prepare the fins for installation on Northrop Grumman's Pegasus XL rocket on July 30, 2018. The Pegasus XL rocket, attached beneath the company's L-1011 Stargazer aircraft, will launch NASA's Ionospheric Connection Explorer (ICON) from the Skid Strip at Cape Canaveral Air Force Station in Florida. Launch is scheduled for Oct. 26. ICON will study the frontier of space - the dynamic zone high in Earth's atmosphere where 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.
Pegasus ICON Fin Arrival and Installation
Northrop Grumman's L-1011 Stargazer is being readied for takeoff June 6, 2018, from the hot pad at Vandenberg Air Force Base in California.  The company's Pegasus XL rocket, containing NASA's Ionospheric Connection Explorer (ICON), is attached beneath the aircraft. The explorer will launch on June 15, 2018, from Kwajalein Atoll in the Marshall Islands (June 14 in the continental United States). ICON will study the frontier of space - the dynamic zone high in Earth's atmosphere where 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.

Pegasus ICON -- L-1011 at Hotpad VAFB
Inside a clean room in Building 1555 at Vandenberg Air Force Base in California, technicians install the second half of the Northrop Grumman Pegasus XL payload fairing around NASA's Ionospheric Connection Explorer (ICON) on Oct. 4, 2018. ICON is being prepared for its launch on the Pegasus XL, which is attached to the company's L-1011 Stargazer aircraft, from the Skid Strip at Cape Canaveral Air Force Station in Florida. Launch is scheduled for Oct. 26. ICON will study the frontier of space - the dynamic zone high in Earth's atmosphere where terrestrial weather from below meets space weather above.
