“…Dust detectors have played an important role in spacecraft payloads since at least the Pioneer 8 mission, probing in situ not only mineral dust but also ice grains . Later ‘active’ detectors produce information about the grains' compositions and, therefore, provide insights into the compositions of the sources from which the grains were emitted .…”

Rationale:Detecting ice grains with impact ionization mass spectrometers in space provides information about the compositions of ice grains and their sources.Depending on the impact speeds of the ice grains onto the metal target of a mass spectrometer, ionization conditions can vary substantially, resulting in changes to the appearance of the resulting mass spectra. Methods:Here we accurately reproduce mass spectra of water ice grains, recorded with the Cosmic Dust Analyzer (CDA) on board the Cassini spacecraft at typical impact speeds ranging between 4 km/s to 21 km/s, with a laboratory analogue experiment. In this Laser-Induced Liquid Beam Ion Desorption (LILBID) approach, a μm-sized liquid water beam is irradiated with a pulsed infrared laser, desorbing charged analyte and solvent aggregates and isolated ions, which are subsequently analyzed in a time-of-flight (TOF) mass spectrometer. Results:We show that our analogue experiment can reproduce impact ionization mass spectra of ice grains obtained over a wide range of impact speeds, aiding the quantitative analyses of mass spectra from space. Conclusions:Spectra libraries created with the LILBID experiment will be a vital tool for inferring the composition of ice grains from mass spectra recorded by both past and future impact ionization mass spectrometers (e.g. the SUrface Dust Analyzer (SUDA) onboard NASA's Europa Clipper Mission or detectors on a future Enceladus Mission).

“…The time resolution of an optical sensor depends on its re-scan frequency, but will be quite low compared with other techniques. Also, the impact crater morphology is (Drolshagen et al, 2001). Those impacts, however, are probably from GTO or other GEO-crossing debris which have higher impact speed.…”

“…Unlike LEO, however, the GEO debris environment is not well characterized. Ground-based GEO optical measurements in general have been limited to objects greater than about 15 cm, and the only in situ measurement, GORID (e.g., Drolshagen et al, 2001), has not been able to provide debris data (e.g., size, velocity) useful to the modeling community. Ongoing GEO debris studies (Jarvis et al, 2002;Schildknecht et al, 2001) has identified substantial numbers of unknown objects, some with diameters less than 70 cm, indicating the possibility of unknown historical breakups or non-fragmentation sources in the GEO region.…”

“…While on-orbit remote sensors have the potential of detecting non-catalogued objects, the millimetre and sub-millimetre realms were only effectively studied with in-situ impact detection techniques (ESA, 2022b). A small number of sensors (passive or active) and surfaces (Oikonomidou et al, 2021;ESA, 2022b) has already provided snapshots of the small population in certain orbital regimes and periods of time, with the DEBIE (Kuitunen et al, 2001;Menicucci et al, 2013) and the GORID (Drolshagen et al, 2001) impact detectors being two characteristic detector examples in LEO and GEO, respectively. While measurements from returned surfaces have already found their way in the validation chain of the small object population of the MASTER model, observations from active insitu detectors have yet to be considered.…”

The Munich Orbital Verification Experiment (MOVE) is a CubeSat student project housed at the Scientific Workgroup for Rocketry and Spaceflight at the Technical University of Munich. MOVE-III is the fourth CubeSat under development, and the first 6U mission of the MOVE project that will carry a dedicated scientific payload in orbit. The mission aims at acquiring in-situ observations of sub-millimetre space debris and meteoroids in Low Earth Orbit, with the objective of compiling a dataset of flux, as well as object mass and velocity measurements that can be used for the validation of the small object estimates of space debris models and support further studies related to the characterisation of the space environment. The MOVE-III CubeSat employs the MOVE-BEYOND platform and is planned to carry three Debris Density Retrieval and Analysis (DEDRA) plasma ionization sensors. The Preliminary Design Review has been completed in early 2022, with the next milestone being the Critical Design Review, planned for 2023. The paper elaborates on the scientific objectives of the mission and the expected data products, provides an overview of the detector operation principle and presents the overall system architecture, the platform configuration and the subsystem interaction. Considerations on the debris mitigation aspects of the mission are additionally discussed.
