Entering Saturn Magnetosphere with a Boom
Jupiter Magnetosphere Made Visible
MMS Spacecraft Animation The Magnetospheric Multiscale (MMS) mission is a Solar Terrestrial Probes mission comprising four identically instrumented spacecraft that will use Earth's magnetosphere as a laboratory to study the microphysics of three fundamental plasma processes: magnetic reconnection, energetic particle acceleration, and turbulence. These processes occur in all astrophysical plasma systems but can be studied in situ only in our solar system and most efficiently only in Earth's magnetosphere, where they control the dynamics of the geospace environment and play an important role in the processes known as "space weather."

Artist Concept of Particle Population in Saturn Magnetosphere
Saturn's magnetosphere is seen for the first time in this image taken by the Cassini spacecraft on June 21, 2004. A magnetosphere is a magnetic envelope of charged particles that surrounds some planets, including Earth. It is invisible to the human eye, but Cassini's Magnetospheric Imaging Instrument was able to detect the hydrogen atoms (represented in red) that escape it. The emission from these hydrogen atoms comes primarily from regions far from Saturn, well outside the planet's rings, and perhaps beyond the orbit of the largest moon Titan. The image represents the first direct look at the shape of Saturn's magnetosphere. Previously, NASA's Voyager mission had inferred what Saturn's magnetosphere would look like in the same way that a blind person might feel the shape of an elephant. With Cassini, the "elephant" has been revealed in a picture. This picture was taken by the ion and neutral camera, one of three sensors that comprise the magnetosphereic imaging instrument, from a distance of about 3.7 million miles (about 6 million kilometers) from Saturn. The magnetospheric imaging instrument will continue to study Saturn's magnetosphere throughout the mission's four-year lifetime. http://photojournal.jpl.nasa.gov/catalog/PIA06345

This chart presents data that the Waves investigation on NASA's Juno spacecraft recorded as the spacecraft crossed the bow shock just outside of Jupiter's magnetosphere on June 24, 2016, while approaching Jupiter. Audio accompanies the animation, with volume and pitch correlated to the amplitude and frequency of the recorded waves. The graph is a frequency-time spectrogram with color coding to indicate wave amplitudes as a function of wave frequency (vertical axis, in hertz) and time (horizontal axis, with a total elapsed time of two hours). During the hour before Juno reached the bow shock, the Waves instrument was detecting mainly plasma oscillations just below 10,000 hertz (10 kilohertz). The frequency of these oscillations is related to the local density of electrons; the data yield an estimate of approximately one electron per cubic centimeter (about 16 per cubic inch) in this region just outside Jupiter's bow shock. The broadband burst of noise marked "Bow Shock" is the region of turbulence where the supersonic solar wind is heated and slowed by encountering the Jovian magnetosphere. The shock is analogous to a sonic boom generated in Earth's atmosphere by a supersonic aircraft. The region after the shock is called the magnetosheath. The vertical bar to the right of the chart indicates the color coding of wave amplitude, in decibels (dB) above the background level detected by the Waves instrument. Each step of 10 decibels marks a tenfold increase in wave power. When Juno collected these data, the distance from the spacecraft to Jupiter was about 5.56 million miles (8.95 million kilometers), indicated on the chart as 128 times the radius of Jupiter. Jupiter's magnetic field is tilted about 10 degrees from the planet's axis of rotation. The note of 22 degrees on the chart indicates that at the time these data were recorded, the spacecraft was 22 degrees north of the magnetic-field equator. The "LT" notation is local time on Jupiter at the longitude of the planet directly below the spacecraft, with a value of 6.2 indicating approximately dawn. http://photojournal.jpl.nasa.gov/catalog/PIA20753
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.

When NASA's Voyager 2 spacecraft flew by Uranus in 1986, it provided scientists' first – and, so far, only – close glimpse of this outer planet. Scientists were confronted by a mystery: The energized particles around the planet defied their understanding of how magnetic fields work to trap particle radiation. The first panel of this artist's concept depicts how Uranus's magnetosphere (its protective bubble) was behaving before Voyager 2's flyby. The second panel shows that an unusual kind of solar weather was happening at the same time as the spacecraft's flyby, giving scientists a skewed view of Uranus's magnetosphere. The work, led by a scientist at NASA's Jet Propulsion Laboratory and described in a paper published in Nature Astronomy in November 2024, contributes to scientists' understanding of this enigmatic planet. It also opens the door to the possibility that Uranus' five major moons may be active. https://photojournal.jpl.nasa.gov/catalog/PIA26069
NASA's Marshall Space Flight Center (MSFC) and university scientists from the National Space Science and Technology Center (NSSTC) in Huntsville, Alabama, are watching the Sun in an effort to better predict space weather - blasts of particles and magnetic fields from the Sun that impact the magnetosphere, the magnetic bubble around the Earth. Filled by charged particles trapped in the Earth's magnetic field, the spherical comet-shaped magnetosphere extends out 40,000 miles from Earth's surface in the sunward direction and more in other directions. This image illustrates the Sun-Earth cornection. When massive solar explosions, known as coronal mass ejections, blast through the Sun's outer atmosphere and plow toward Earth at speeds of thousands of miles per second, the resulting effects can be harmful to communication satellites and astronauts outside the Earth's magnetosphere. Like severe weather on Earth, severe space weather can be costly. On the ground, magnetic storms wrought by these solar particles can knock out electric power. By using the Solar Vector Magnetograph, a solar observation facility at MSFC, scientists are learning what signs to look for as indicators of potential severe space weather.

MMS, led by a team from NASA's Goddard Space Flight Center, is a Solar Terrestrial Probes mission consisting of four identically instrumented spacecraft that will use Earth’s magnetosphere as a laboratory to study the microphysics of three fundamental plasma processes: magnetic reconnection, energetic particle acceleration and turbulence. Launch aboard a United Launch Alliance Atlas V rocket from Space Launch Complex 41 on Cape Canaveral Air Force Station is targeted for March 12, 2015.
