"Hirai Chisato" appears to refer to two distinct researchers, and Chisato Okamoto , who collaborated on the ALADDIN (Arrayed Large-Area Dust Detectors in INterplanetary space) dust detector. This instrument was a key feature of the IKAROS (Interplanetary Kite-craft Accelerated by Radiation Of the Sun) solar sail mission. Key Feature: The ALADDIN Dust Detector
: It was deployed on the anti-Sun face of the spacecraft's thin polyimide sail membrane.
: Between 2010 and 2011, it successfully measured micrometeoroid flux in the inner planetary region between the orbits of Earth and Venus.
The ALADDIN instrument, detailed in research published by Cambridge University Press and documented by the ESA's eoPortal , featured the following technical specifications:
: It utilized PVDF (Poly Vinylidene DiFluoride) sensors, which are capable of detecting hypervelocity impacts from micrometeoroids. Surface Area : The detector covered an area of .
: The 8-channel sensors, ranging from 9 to 20 microns in thickness, could detect particles with a mass greater than approximately
