"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
The ALADDIN instrument, detailed in research published by Cambridge University Press and documented by the ESA's eoPortal , featured the following technical specifications: hirai chisato
: Between 2010 and 2011, it successfully measured micrometeoroid flux in the inner planetary region between the orbits of Earth and Venus. "Hirai Chisato" appears to refer to two distinct
: The 8-channel sensors, ranging from 9 to 20 microns in thickness, could detect particles with a mass greater than approximately : The 8-channel sensors, ranging from 9 to
: It utilized PVDF (Poly Vinylidene DiFluoride) sensors, which are capable of detecting hypervelocity impacts from micrometeoroids. Surface Area : The detector covered an area of .
: It was deployed on the anti-Sun face of the spacecraft's thin polyimide sail membrane.
