SPASE version 2.0.0

Name
Magnetic Field (HED/VHM/FGM)
Alternate name
FGM
HED
VHM
Description

The objectives of this investigation are to determine the strength and geometry of the interplanetary magnetic field in the inner heliosphere (particularly at high solar latitudes) and to investigate the heliographic latitude dependence of the field fluctuation spectra with special emphasis on the frequency range below 0.01 Hz. Secondary objectives are to study the internal dynamics of the solar wind, the role of discontinuities and waves in the interplanetary field on propagation and acceleration of energetic particles, the interplanetary propagation and development of discontinuities and waves, and the structure and dynamics of the dusk region of the Jovian magnetosphere. The instrument consists of a triaxial fluxgate magnetometer, a vector helium magnetometer, and associated electronics. The instrument has a mass of 4.75 kg and uses 5.4 W of power. It has a data rate of 40 bps in the cruise mode and 80 bps in the tracking mode.

SWOOPS
Description

The objectives of this investigation are (1) to investigate and characterize bulk-flow parameters and internal-state conditions of the solar wind as functions of solar latitude; (2) to investigate radial variations of solar wind properties between Earth and Jupiter; and (3) to investigate the solar wind interactions with the Jovian magnetosphere. The instrument consists of two sensor systems and associated electronics that interface with the spacecraft. Electrons in the energy range between 1 and 900 eV are measured by a 120-deg spherical-section electrostatic analyzer with seven channel electron multipliers (CEMs) which cover a polar angle range of 146 deg. The plate spacing is 0.35 cm and the average radius of curvature is 4.2 cm. The solar wind ion analyzer makes three-dimensional measurements of solar-wind ions with energies in the range between 257 eV and 35 keV per charge. It consists of a 105-deg spherical-section electrostatic analyzer fitted with 16 CEM sensors which cover a polar angle range of 80 deg. It is mounted so that the first CEM views along the spin axis direction and the sixteenth at a polar angle of 75 deg from the spin axis. A stepping motor is used to rotate any one of seven apertures into place. The mass of the electron instrument is 2.6 kg. It uses 2.6 W of power and has a data rate of 24 bps in storage mode and 48 bps in tracking mode. The mass of the ion instrument is 4.1 kg. It uses 2.9 W mean and 7 W peak power, and has a data rate of 56 bps in storage mode and 112 bps in tracking mode.

Description

The primary objectives of Ulysses, formerly the International Solar Polar Mission (ISPM), are to investigate, as a function of solar latitude, the properties of the solar wind and the interplanetary magnetic field, of galactic cosmic rays and neutral interstellar gas, and to study energetic particle composition and acceleration. The 55 kg payload includes two magnetometers, two solar wind plasma instruments, a unified radio/plasma wave instrument, three energetic charged particle instruments, an interstellar neutral gas sensor, a solar X-ray/cosmic gamma-ray burst detector, and a cosmic dust sensor. The communications systems is also used to study the solar corona and to search for gravitational waves. Secondary objectives included interplanetary and planetary physics investigations during the initial Earth-Jupiter phase and investigations in the Jovian magnetosphere. The spacecraft used a Jupiter swingby in Feb. 1992 to transfer to a heliospheric orbit with high heliocentric inclination, and will pass over the rotational south pole of the sun in mid-1994 at 2 AU, and over the north pole in mid-1995. A second solar orbit will take Ulysses again over the south and north poles in years 2000 and 2001, respectively. The spacecraft is powered by a single radio-isotope generator. It is spin stabilized at a rate of 5 rpm and its high-gain antenna points continuously to the earth. A nutation anomaly after launch was controlled by CONSCAN. The original mission planned for two spacecraft, one built by ESA and the other by NASA. NASA cancelled its spacecraft in 1981.
