Rosetta Lander: ROMAP
Back   Additional Information: The Rosetta Lander Website		The Rosetta Lander experiment ROMAP consists as the Magnetometer, Electrostatic Analyser and Faraday Cup. The instrument delivers data about the comet / solar wind interaction and the cometary activity as function of the distance from the sun and the onset of the diamagnetic cavity formation. Electrostatic Analyser and Faraday Cup are able to determine the major solar wind parameters like density, speed, temperature, and flow direction by measuring ions up to 8.000keV and electrons up to 4.200keV. The Magnetometer is able to determine the magnetic field vector up to 32Hz.   Romap Sensor Frontview  For the first time ever, the ROSETTA mission will provide magnetic field measurements at very low distances from a cometary nucleus in a situation where the cometary activity is not yet fully developed. If the nucleus is not protected by an atmosphere produced by outgassing, the solar wind interacts directly with the intrinsic field. In addition, during the approach to the nucleus, the probe can measure the variation of the magnetic field with distance and thus one should be able to clearly identify the type of the possible remnant magnetization. Romap electronics Romap Sensor Sideview The Figures show the high integration level of sensors and electronics. That is the basic for a combined field/plasma measurement instrument with less than 1 Watt power consumption and 1 kg mass. Volume Model of the Romap Sensor. The Magnetometer sensor with Helmholtz system is located inside the electrostatic analyser. The Faraday Cup is located on the top of the Magnetometer sensor.
