Seven different solar physics experiments have been flown on the Spacelab facility. In the following we shall refer to them by their acronymes as follows: ACRIM - Active Cavity Radiometer Irradiance Monitor. The primary objective is to determine the degree and direction of possible fluctuations in the sun's total output of optical energy (x-rays to microwave wavelengths)by measuring the total solar optical irradiance outside the earth's atmosphere. SUSIM - Solar Ultraviolet Spectral Irradiance Monitor. The objective is to determine both long-term and short-term variations of the total ultraviolet flux emitted by the sun. SOLSPEC - Solar Spectrum Measurement from 180 to 3200 Nanometers. The objective is to measure the solar energy in the ultraviolet, visible and infrared parts of the spectrum, and to determine the amounts of energies in this spectral irradiance, and how they change with time. SOLCON - Measurement of the Solar Constant. The purposes are to measure the absolute value of the total solar irradiance and to detect and measure long-term variations that may exist in its absolute value. SOUP - Solar Optical Universal Polarimeter. The objectives of the experiment are: to measure magnetic and velocity fields in the solar atmosphere; to follow the evolution of solar magnetic structures over periods of several days to determine how magnetic elements couple to the supergranula velocity patterns and by what mechanisms field diffusion and disappearance occur; to study with high temporal and spatial resolution the magnetic field changes associated with transient events; and to provide a test of the pointing accuracy and stability of the Instrument Pointing System (IPS) to sub-arc second accuracy. CHASE - Coronal Helium Abundance Spacelab Experiment. The goal of this experiment is to determine accurately the helium abudance of sun. HRTS Solar Ultraviolet High Resolution Telescope and Spectrograph. Purpose: to investigate the energy transport and mass balance of the temperature minimum, chromosphere, transition zone, and corona in the quiet sun as well as in plages, flares and sunspots; to study the velocity field of the lower corona in order to investigate the origin of the solar wind; to investigate the structure of spicules and superspicules; to investigate the structure and dynamics of prominences; and to study the preflare and flare phenomena.
