Interplanetary and interstellar dust observations by Mars dust counter on board NOZOMI: four-year operation

In situ measurement of interplanetary and interstellar dust particles by Mars Dust Counter (MDC) is reported here. MDC is a light-weight impact-ionization dust detector on board Japanese Mars mission NOZOMI, which was launched on July 4th 1998. In four years between July 1998 and April 2002, MDC has...

Zusammenfassung:In situ measurement of interplanetary and interstellar dust particles by Mars Dust Counter (MDC) is reported here. MDC is a light-weight impact-ionization dust detector on board Japanese Mars mission NOZOMI, which was launched on July 4th 1998. In four years between July 1998 and April 2002, MDC has detected more than 100 dust impacts. In November 1998, NOZOMI encountered the Leonid meteoroid stream. Although MDC detected two dust impacts, directional analysis showed that those probably did not belong to the Leonid particles. In the interplanetary observation from 1999, NOZOMI has detected more than 80 interplanetary particles moving around the sun and several particles of interstellar origin. From 2004, MDC-NOZOMI will start measuring distribution of the martian ring or torus of dust from Phobos and Deimos.
