Constraining the Martian Meteoroid Environment: Supporting the Preliminarily Selected MeteorCam for LightShip-

Maximilian Vovk, Peter Brown, Denis Vida, Mark Millinger et autres

We present work supporting the preliminarily selected MeteorCam instrument for the LightShip-1 mission (shown in Fig.1). Earlier LightShip studies considered both nightside Martian fireball imaging and in situ dust impact detection [1], but our focus is the selected space-based meteor camera concept …

The Dynamical Origin of Millimetre-Sized Sporadic Meteoroids

Tam Do, Peter Brown, Petr Pokorný

Determining the relative contributions of cometary and asteroidal sources to the sporadic meteoroid population remains a longstanding challenge, particularly because commonly used orbit-based classification criteria have not been rigorously validated for meteoroids. We evaluate the efficacy of several established orbit-based criteria for …

Future Strengthening of North Atlantic Anthropogenic Carbon Transport Despite AMOC Weakening

Ce Bian, Galen McKinley, Peter Brown, Elaine McDonagh

The North Atlantic is a major hotspot for the uptake, accumulation, and storage of anthropogenic carbon (Canth), processes that are closely linked to the Atlantic Meridional Overturning Circulation (AMOC). However, the role of ocean transport in driving this accumulation remains poorly constrained, …

Face aux entreprises privées qui se ruent vers les étoiles, une gouvernance internationale de l’espace devient indispensable

Peter Brown

L’espace proche de la Terre devient de plus en plus encombré. Collisions, pollution lumineuse, impacts sur l’astronomie et sur l’atmosphère : pour les scientifiques du G7, il devient urgent de fixer des limites avant d’atteindre un point de bascule.

Preventing and correcting spread of misinformation about near‐Earth objects, impacts, airbursts, and planetary defense: Case studies

Mark Boslough, Peter Brown, Andy Bruno, Paul Chodas et autres

Abstract The landscape of scientific publishing and communication is changing rapidly with the accelerating growth of open‐access outlets that lack rigorous peer review, revenue‐driven online media, inadequately trained journalists, social media, online influencers, podcasts, celebrity endorsements of pseudoscience, anti‐science political movements, and …

Meteor Statistics. I. The Distribution of Instrumental Magnitudes

Althea V. Moorhead, Peter Brown, M. Campbell‐Brown, Michael J. Mazur et autres

Abstract The distribution of meteor magnitudes is known to follow an exponential distribution, where the base of this distribution is called the population index. The distribution of observed magnitudes preserves this behavior, but is truncated by the detection threshold. If both the …

Signal characteristics of potential airbursts in Titan’s atmosphere

Elisa Dong, C. D. Neish, John E. Moores, Shigeru Wakita et autres

We investigate the possibility of detecting airbursts in Titan’s atmosphere by considering their burst characteristics (height and energy release) and associated overpressure and surface displacement. To simulate the airbursts, we track the progression of meteors through the atmosphere using the Separate Fragments …
