            "title": "NASA Mission to Study Giant ‘Halo’ Surrounding Earth",
            "description": "In 1972, Apollo 16 astronauts placed an ultraviolet camera on the Moon that captured the first images of Earth’s geocorona, the light emitted by Earth’s outermost atmospheric layer. A new NASA mission bearing the name of the telescope’s creator, Dr. George R. Carruthers, will launch into space to build on that legacy. From a vantage point roughly one million miles closer to the Sun than Earth is, the Carruthers Geocorona Observatory will capture the most comprehensive views of the geocorona to date. The observations will reveal new insights into the structure of our atmosphere, how solar eruptions impact Earth, and how a planet’s surface water can escape to space, aiding the search for habitable planets elsewhere in the universe.Learn more about Carruthers Geocorona Observatory science: https://science.nasa.gov/science-research/heliophysics/new-nasa-mission-to-reveal-earths-invisible-haloLearn more about the Carruthers Geocorona Observatory: https://science.nasa.gov/mission/carruthers-geocorona-observatory/ || ",

            "title": "Heliophysics Overview",
            "description": "Heliophysics is the study of the Sun, and how it influences the very nature of space — and, in turn, the atmospheres of planets and the technology that exists there. Space is not, as is often believed, completely empty; instead, we live in the extended atmosphere of an active star. Our Sun sends out a steady outpouring of particles and energy -- the solar wind – as well as a constantly writhing magnetic system. This extensive, dynamic solar atmosphere surrounds the Sun, Earth, the planets, and extends far out into the solar system.Studying this system not only helps us understand fundamental information about how the universe works, but also helps protect our technology and astronauts in space. NASA seeks knowledge of near-Earth space, because -- when extreme -- space weather can interfere with our communications, satellites and power grids. The study of the Sun and space can also teach us more about how stars contribute to the habitability of planets throughout the universe.Mapping out this interconnected system requires a holistic study of the Sun’s influence on space, Earth and other planets.  NASA has a fleet of spacecraft strategically placed throughout our heliosphere -- from Parker Solar Probe at the Sun observing the very start of the solar wind, to satellites around Earth, to the farthest human-made object, Voyager, which is sending back observations on interstellar space. Each mission is positioned at a critical, well-thought out vantage point to observe and understand the flow of energy and particles throughout the solar system -- all helping us untangle the effects of the star we live with. || ",

            "title": "Comparative Magnetospheres: A Carrington-Class CME",
            "description": "In an effort to understand and predict the impact of space weather events on Earth, the Community-Coordinated Modeling Center (CCMC) at NASA Goddard Space Flight Center, routinely runs computer models of the many historical events. These model runs are then compared to actual data to determine ways to improve the model, and therefore forecasts of the impacts of future space weather events.But sometimes we don't have an actual event where we have lots of data for comparison.  Extreme space weather events are one example where we must test models with a rather limited set of data.This is a model run used to examine the consequences if a large coronal mass ejection (CME) such as The Carrington-Class CME of 2012 had actual hit Earth.  Such model runs allow us to estimate consequences of a large event hitting Earth so we can better protect power grids and satellites.Some of the conclusions from this model run are (documented in the paper linked below):The magnetopause is compressed to the point it is moved inside the orbits of our geosynchronous satellites.Large field-aligned currents are created on the night-side of Earth, generating large ionospheric potentials.At high latitudes, geo-electric fields of 26 volts per kilometer can be generated.For comparison, the geo-electric field of the March 1989 storm which generated an extensive power outage in Canada (Wikipedia) had a value of only about 6 volts per kilometer; and the 2003 Halloween solar storms (see Halloween Solar Storms 2003) generated a field of about 12 volts per kilometer. || ",
