abstract = {The number of artificial objects in space increases due to
past and present space activities. To analyse the quantity
of the small (diameter >100 μm up to cm) space debris and
meteoroids, an innovative in-situ impact detection method
has been developed at DLR (German Aerospace Center) in
Bremen, Germany. The method Solar panel-based Impact
Detector “SOLID” uses solar panels for impact detection.
Since solar panels provide large detection areas and exist
on nearly all satellites, this method enables for the
collection of large amounts of data in different orbits. An
impacting object generates a permanent damage on a panel.
The damage can be determined during analysis scan as well as
confirmed or refuted in the frame of subsequent scans of the
panels. Those properties of the sensor system can
significantly improve the amount as well as the quality of
measurement data to be used for environmental model
validation. The SOLID method was successfully verified on
ground by Hypervelocity Impact (HVI) tests at Fraunhofer
EMI, Freiburg, Germany. The ability of the detection method
SOLID for impact detection of space debris and meteoroids
was clearly demonstrated on ground. Since July 2017, the
SOLID sensor system is placed in a 600 km Sun-synchronous
orbit on the microsatellite mission TechnoSat of Technische
Universität Berlin (TUB). Four solar panels equipped with
SOLID technology are installed on the satellite for in-orbit
testing and environmental exploration. The total detection
area of all panels is about 0.0755 m$^2$. The system was
designed to detect space debris or meteoroid objects with a
diameter larger than 100 μm. In total 15,570,047 scans were
performed over the four years in space. By means of
measurement data changes were identified on one panel.
However, so far, the telemetry data shows no clear evidence
for an impact.},
