insulation). CLOTH will detect and evaluate the impact
flux of micrometeoroid around the cis-lunar region by
using piezoelectric dust-impact detectors onboard the
spacecraft. The primary goal of this mission is to provide
the first insight of spatial distribution of sub-mm solid
objects in the cis-lunar space, which will complement
DELPHINUS' optical observation of lunar impact flashes
by cm-order solid objects. By combining results of both
CLOTH and DELPHINUS, we will learn spatial distribution and temporal variation of solid objects in the cis-lunar
space from microns to 10's of cm orders, which will benefit both solar system science and risk assessment of human
exploration of the Moon in the future.
In general, a statistically valid detection of microparticle impacts requires a large sensor area. On the contrary, a
dedicated dust detector that occupies a large portion of a
34
total surface area of a spacecraft exterior seems unfeasible
for very limited resources available in size and mass of a
CubeSat. Thus, we have resolved this contradiction by
introducing a new concept of a "smart MLI," which integrates thin-film dust detectors (PVDF piezoelectric films)
into inside of the spacecraft's thermal blanket, MLI (multilayer insulation) (see Figure 5). To demonstrate the new
concept of the MLI with momentum sensing capability for
the first time in space is the secondary goal of this mission,
which will potentially game change meteoroid and space
debris monitoring in space, since this technology will
enable any satellites/spacecraft in any orbits to detect dust
impacts as house-keeping data of the MLI exterior.
As a microparticle impacts onto the CLOTH at hypervelocity speed, detection signals from the PVDF film sensors
