The micrometeoroid experiment onboard Helios allowed the measurement of physical and chemical characteristics of interplanetary dust particles between 0.3AU and 1AU solar distance. During the first 10 orbits of Helios 1,235 impacts of micrometeoroids were detected. Eighty-three particles were registered by the ecliptic sensor and 152 by the south sensor. Most of the particles detected by the ecliptic sensor impacted the sensor from the apex direction. The particles observed by the south impacted the sensor from all directions with a slightly enhanced flux from solar direction. The average of impact speed of particles was 15 km/s. From 1AU to 0.3AU, the observed particle flux increased by a factor 5 to 10. The orbits of the registered particles are highly eccentric, e or approximately 0.6, and some are hyperbolic. The mass spectra measured upon impact allow the classification of the chondritic and iron rich particles.
