A small quantity of useful scientific information was returned, showing the radiation surrounding Earth was in the form of bands and measuring the extent of the bands, mapping the total ionizing flux, making the first observations of hydromagnetic oscillations of the magnetic field, and taking the first measurements of the density of micrometeorites and the Interplanetary Magnetic Field.

When the magnetic lines of force are connected with the interplanetary magnetic field ( IMF ) in the appropriate direction, the strahl electrons are transported from the solar corona with energies of up to several hundred eV . When the Sun's magnetic field lines are not connected with the IMF, the strahl effect is blocked at that pole.
