The Solar Isotope Spectrometer provides isotopically resolved measurements of the elements from lithium to zinc over the energy range 10 - 100 MeV/nucleon. The SIS dectector system consists of two identical telescopes composed of stacks of large-area solid-state detectors.
The Geotail mission is a collaboration between NASA and the Institute of Space and Astronautical Science (ISAS) of Japan. Its primary objective is to study the dynamics of Earth's magnetotail over a wide range of distances, extending from the near-Earth region to as far as about 200 Earth radii from the planet. The Geotail spacecraft measured global energy flow and transformation in the magnetotail to increase understanding of fundamental processes at work. Since February 1995, Geotail has provided data on most aspects of the solar wind interaction with the magnetosphere. Geotail was designed and built by ISAS and launched in 1992.
IBEX is the first mission designed to map the entire boundary region at the edge of the solar system. As electrically charged particles from the sun (the solar wind) flow outward beyond the orbits of the planets, they collide with the material between the stars -- the interstellar medium, or ISM. These interactions create energetic neutral atoms (ENAs), fast-moving particles with no charge. This region emits no light that can be collected by conventional telescopes, so IBEX, measures the ENAs that happen to be traveling inward from the boundary. IBEX's sole science objective is to discover the nature of the interactions between the solar wind and the interstellar medium at the edge of our solar system. The mission launched in 2008.
Polar mission provided multi-wavelength imaging of the aurora, measuring the entry of plasma into the polar magentosphere and the geomagnetic tail, the flow of plasma to and from the ionosphere, and the deposition of particle energy in the ionosphere and upper atmosphere.
Polar, Wind and Geotail program is a part of the International Solar-Terrestrial Physics (ISTP) Science initiative, combining resources and scientific communities to obtain coordinated, simultaneous investigations of the Sun-Earth space environment over an extended period of time.
Super Trans-Iron Galactic Element Recorder (Super-Tiger) is a large-area instrument for measurement of the abundances of elements of atomic number Z in the interval 30≤Z≤42; with an unprecedented combination of individual-element resolution and statistical precision and will make exploratory measurements through Z=56.
The Virtual Energetic Particle Observatory (VEPO) serves the heliophysics data user community as a focus group component operating within the domain of the Virtual Heliospheric Observatory (VHO) for improved discovery, access, understandability, and usability of energetic particle data products from selected spacecraft and sub-orbital instruments within the VEPO Data Source Environment.
The Virtual Heliospheric Observatory (VHO) provides a single point of uniform discovery, access, and use of data about the heliosphere. The VHO accomplishes this goal by uniting a number of distributed repositories for heliospheric data. VHO is a project within NASA's Heliophysics Data Environment and is maintained within the Heliospheric Physics Laboratory at NASA's Goddard Space Flight Center. The VHO utilizes the SPASE data model and provides uniform metadata for heliopheric data sets. A prominent feature of the VHO is the query interface, which provides uniform access to the distributed data sets within VHO. The VHO actively collaborates with the Virtual Energetic Particle Observatory and the Virtual Waves Observatory to enable access to energetic particle and waves data, respectively.
The Virtual Space Physics Observatory (VSPO) is an evolving system for making data easily available from all missions relevant to the global problem of the effects of solar particles and fields on the Earth. The VSPO is one of several efforts towards the Living With A Star Data Environment (LWSDE).
The Voyager Cosmic Ray Subsystem (CRS) is designed to exploit to the fullest practical degree the proposed trajectories of Voyager-1 and -2. The significance of these measurements will be greatly enhanced by concurrent measurements with similar particle telescopes on satellites such as the Pioneers, IMPs, and similar series in near-earth orbits.
The Wind mission's goals are to study the magnetosphere and ionosphere and investigate basic plasma processes occurring in the near-Earth solar wind. The Wind spacecraft orbits upstream from Earth in the solar wind, which is the flow of electrically charged particles streaming from the surface of the sun. Wind observes the solar wind before it impacts Earth's magnetic field. The spacecraft was launched in 1994.
Magnetic Field Investigation (MFI) instrument, onboard the WIND spacecraft, was based on the magnetometers previously developed for the Voyager, ISPM, GIOTTO, and Mars Observer missions which represent state-of-the-art instruments with unparalleled performance.
