The mysterious Martian potato: An experimental investigation into the origin of Phobos Open
Background:Despite extensive study, the Mars system still possesses many mysteries, one of which is the formation of its moons Phobos and Deimos. Several mechanisms have been proposed but weather the moons formed as re-accreted ejecta [1] …

Experimental ice:silicate craters and their application to Mars Open
Background:The morphology of impact craters has been used to study the surface and near-surface properties of many bodies throughout the Solar System. Comparative planetological methods have then furthered this to infer specific parameters…

Preliminary results of experimental investigations of the transfer of Martian material to Phobos Open
The transfer of material between the surfaces of Mars and Phobos is thought to be a key parameter in understanding the formation/evolution of the Martian moons. Past numerical investigations have predicted that, on average, 255 ppm of Mart…

Synthesis of Phenanthrene/Pyrene Hybrid Microparticles: Useful Synthetic Mimics for Polycyclic Aromatic Hydrocarbon-Based Cosmic Dust Open
Polycyclic aromatic hydrocarbons (PAHs) are found throughout the interstellar medium and are important markers for the evolution of galaxies and both star and planet formation. They are also widely regarded as a major source of carbon, whi…

Experimental investigation of impact cratering on Phobos Open
JAXA’s Martian Moon eXploration (MMX) sample return mission aims to solve the long-debated origin of Martian moons Phobos and Deimos [1].This will be the first attempt to sample an object that either formed in the outer solar system …

Hypervelocity impact induced light flash experiments on single and dual layer Kapton targets to develop a time of flight space dust and debris detector Open
The impact flash from hypervelocity impact on thin (12.5 µm) Kapton film was observed. The projectile sizes ranged from 0.1 to 1 mm, with speeds from 2 to 5 km s−1 and penetrated the Kapton intact, leaving holes the same size as the projec…

Synthesis of Autofluorescent Phenanthrene Microparticles via Emulsification: A Useful Synthetic Mimic for Polycyclic Aromatic Hydrocarbon-Based Cosmic Dust Open
Phenanthrene is the simplest example of a polycyclic aromatic hydrocarbon (PAH). Herein, we exploit its relatively low melting point (101 °C) to prepare microparticles from molten phenanthrene droplets by conducting high-shear homogenizati…

The fusion crust of the Winchcombe meteorite: A preserved record of atmospheric entry processes Open
Fusion crusts form during the atmospheric entry heating of meteorites and preserve a record of the conditions that occurred during deceleration in the atmosphere. The fusion crust of the Winchcombe meteorite closely resembles that of other…

Emission Spectroscopy for the Temperature Measurement of Salt-Water Ice during Hypervelocity Impact Open
IntroductionThe intense, short-lived, self-luminous plume (or ‘impact flash’) produced from a hypervelocity impact is frequently observed on the lunar surface [1-4]. Laboratory measurements of these impact flashes (e.g. Figure …

Impact flash evolution of CO<sub>2</sub> ice, water ice, and frozen Martian and lunar regolith simulant targets Open
The wavelength dependence and temporal evolution of the hypervelocity impact self‐luminous plume (or “flash”) from CO 2 ice, water ice, and frozen Martian and lunar regolith simulant targets have been investigated using the Kent two‐stage …

Observations of impacted, frozen Lunar and Martian regolith simulants Open
An examination of impact flashes from frozen Lunar and Martian simulant (JSC-1A and JSC-1 respectively) was carried out in order to better understand the physical and chemical behaviour of the highly energetic, short-lived, ejecta cloud. T…

Infrared Spectroscopy of NaCl(CH<sub>3</sub>OH)<sub><i>n</i></sub> Complexes in Helium Nanodroplets Open
Infrared (IR) spectra of complexes between NaCl and methanol have been recorded for the first time. These complexes were formed in liquid helium nanodroplets by consecutive pick-up of NaCl and CH3OH molecules. For the smallest NaCl(CH3OH)n…

Communication: Infrared spectroscopy of salt-water complexes Open
To explore how the ion-pair in a single salt molecule evolves with the addition of water, infrared (IR) spectra of complexes composed of NaCl and multiple water molecules have been recorded for the first time. The NaCl(H2O)n complexes were…
