Abstract The discovery of ‘Oumuamua and CNEOS 2014-01-08 allowed for a calibration of the impact rate of interstellar objects. We propose a new telescope in lunar orbit to study in real-time interstellar meteoroid impacts and to serve as a laboratory for hypervelocity collisions. We show that a telescope with diameter D a ≳ 2 m would be capable of detecting ≳ 1 interstellar meteoroid impacts (among hundreds of Solar System meteoroid impacts) per year. For each meteoroid, measurements of the…

Impacts of Dust Grains Accelerated by Supernovae on the Moon
There is evidence that ejecta from nearby supernovae have rained down on Earth in the past. Supernovae can accelerate pre-existing dust grains in the interstellar medium to speeds of $\sim 0.01
The New Astronomical Frontier of Interstellar Objects
The upcoming commencement of the Vera C. Rubin Observatory’s Legacy Survey of Space of Time (LSST) will greatly enhance the discovery rate of interstellar objects (ISOs). ‘Oumuamua and Borisov were
A cosmic dust detection suite for the deep space Gateway
The decade of the 2020s promises to be when humanity returns to space beyond Earth orbit, with several nations trying to place astronauts on the Moon, before going further into deep space. As part of


Detection of sporadic impact flashes on the Moon : Implications for the luminous efficiency of hypervelocity impacts and derived terrestrial impact rates
Abstract We present the first redundant detection of sporadic impact flashes on the Moon from a systematic survey performed between 2001 and 2004. Our wide-field lunar monitoring allows us to
Probing Extrasolar Planetary Systems with Interstellar Meteors
The first interstellar object, `Oumuamua, was discovered in the Solar System by Pan-STARRS in 2017, allowing for a calibration of the impact rate of interstellar meteors of its size $\sim 100\;$m.
Detection of an intergalactic meteor particle with the 6-m telescope
On July 28, 2006 the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences recorded the spectrum of a faint meteor. We confidently identify the lines of FeI and
Hypervelocity Impact Experiments in the Laboratory Relating to Lunar Astrobiology
The results of a set of laboratory impact experiments (speeds in the range 1–5 km s−1) are reviewed. They are discussed in the context of terrestrial impact ejecta impacting the Moon and hence lunar
The flux of kilogram-sized meteoroids from lunar impact monitoring
Abstract The flashes from meteoroid impacts on the Moon are useful in determining the flux of impactors with masses as low as a few tens of grams. A routine monitoring program at NASA’s Marshall
Temperatures of lunar impact flashes: mass and size distribution of small impactors hitting the Moon
Lunar impact flashes have been monitored over the last 20 years for determining the mass frequency distribution of near-Earth objects in the cm-dm size range. In this work, using telescopic
Implications of the interstellar object 1I/'Oumuamua for planetary dynamics and planetesimal formation
'Oumuamua, the first bona-fide interstellar planetesimal, was discovered passing through our Solar System on a hyperbolic orbit. This object was likely dynamically ejected from an extrasolar
An Observational Upper Limit on the Interstellar Number Density of Asteroids and Comets
We derived 90% confidence limits (CL) on the interstellar number density ($\rho_{IS}^{CL}$) of interstellar objects (ISO; comets and asteroids) as a function of the slope of their size-frequency
Estimation of hypervelocity impact parameters from measurements of optical flash
Abstract When meteoroids and orbital debris hit satellites or surfaces of other objects in space, an optical flash is generated. Measuring properties of this impact flash can reveal several important
