The case for a deep search for Earth’s Trojan asteroids [PDF]

open access: yesNature Astronomy, 2019
The existence of Earth's Trojan asteroids is not well constrained and represents a major gap in our inventory of small bodies in near-Earth space. Their discovery would be of high scientific and human interest.

Compliant Robotics in Space: A Prospective Review of Soft and Deformable Systems for Space Missions

open access: yesAdvanced Intelligent Systems, EarlyView.
Compliant robots are increasingly becoming integral to space exploration due to their adaptability, flexibility, and lightweight design. This article reviews categories such as soft, reconfigurable, and hyper‐redundant robots and their evolving role in enhancing space missions.

AsteroidFinder – the space-borne telescope to search for NEO Asteroids [PDF]

open access: yesInternational Conference on Space Optics — ICSO 2010, 2017
This paper presents the mission profile as well as the optical configuration of the space-borne AsteroidFinder telescope. Its main objective is to retrieve asteroids with orbits interior to Earth’s orbit. The instrument requires high sensitivity to detect asteroids with a limiting magnitude of equal or larger than 18.5mag (V-Band) and astrometric ...

Ion Source Complementarity for Characterization of Complex Organic Mixtures Using Fourier Transform Mass Spectrometry: A Review

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Complex organic mixtures are found in many areas of research, such as energy, environment, health, planetology, and cultural heritage, to name but a few. However, due to their complex chemical composition, which holds an extensive potential of information at the molecular level, their molecular characterization is challenging.

Earth Trojan Asteroids: A Study in Support of Observational Searches

open access: yesIcarus, 2000
Observational searches for asteroids orbiting near Earth's triangular Lagrange points face unique obstacles. A population of such asteroids would occupy a large projected area on the sky (possibly hundreds of square degrees) and is not favorably placed with respect to the Sun. Here we examine the properties of synthetic populations of Earth ``Trojans''

Searching for Binary Asteroids in Pan-STARRS1 Archival Images

open access: yesThe Planetary Science Journal, 2022
Abstract We developed two different point-spread function (PSF) analysis techniques for discovering wide separation binary asteroids in wide-field surveys. We then applied these techniques to images of main belt asteroids in the 4–60 km size range captured by Pan-STARRS1.

Enhancing the Resilience of Platinum Group Metal Supply Chains: Mine to (Re)use

open access: yesSustainable Development, EarlyView.
ABSTRACT Platinum group metals (PGMs) are critical elements that play a vital role in sustainable energy transition technologies such as catalysts, hydrogen production and use, and electronics. Securing a resilient PGM supply chain would support the current industrial, societal, and economic infrastructure.

A successful search for hidden Barbarians in the Watsonia asteroid family [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society: Letters, 2014
Abstract Barbarians, so named after the prototype of this class (234) Barbara, are a rare class of asteroids exhibiting anomalous polarimetric properties. Their very distinctive feature is that they show negative polarization at relatively large phase angles, where all ‘normal’ asteroids show positive polarization.
