Introduction
As part of the Europa Lander concept team at JPL, I am providing science support to Lander concept development and reconnaissance planning for Europa Clipper. I recently completed my Ph.D. at UCL, where I processed and used 3D orbital imagery and virtual outcrop analysis to probe the geological history of Gale Crater, Mars.

Article
Full-text available
Digital Terrain Models (DTMs) provide valuable insights into the nature of solar system surfaces, facilitating geological analysis, landing site selection and characterisation, and contextualising in situ measurements. For missions or solar system bodies for which orbiters and soft landed platforms are technologically or financially challenging to...
Conference Paper
Full-text available
A combined HiRISE, CTX, and HRSC digital terrain model (DTM) of Gale Crater was processed using CASP-GO and the KM09-VICAR system. "Rover eye" Navcam views over the MSL rover traverses have been visualized in a 3D environment. These simulated views demonstrate a useful combination of different resolution imagery for rover mission planning, localiza...

Abstract The Central Elysium Planitia (CEP) is one of the youngest geological units on Mars and displays evidence of volcanic and fluvial activities on the surface. The origin of the CEP material has long been debated with a range of hypotheses from purely fluvial to solely volcanic origins. This study presents a comprehensive investigation of SHAl...
Conference Paper
Full-text available
We present an overview of Space Science in Context (SSiC) 2020 conference, which brought together a community of scholars interested in developing interdisciplinary knowledge and practice around contexts of space science research globally. We then describe key lessons learned from the event and develop four key recommendations for the community: pu...
Data
This dataset comprises a unit map derived from 3D analysis of Sakarya Vallis in Gale crater, Mars.
Data
This multi-resolution, multi-spectral basemap comprises HiRISE, CTX, MOC-NA, and CRISM imagery over the northwest of Aeolis Mons in Gale crater, Mars, to complement the HiRISE and CTX data over Sakarya Vallis (Persaud 2021, https://doi.org/10.5281/zenodo.5808371; Persaud et al. 2021, https://doi.org/10.5281/zenodo.5808357).
Data
Local digital terrain model (DTM) and orthorectified image (ORI) of Sakarya Vallis, west of Aeolis Mons in Gale crater, Mars. The DTM was originally processed by the University of Arizona (DTEEC_006855_1750_007501_1750_A01, https://www.uahirise.org/dtm/dtm.php?ID=PSP_006855_1750); this product is co-registered to CTX DTMs which were themselves co-r...
Data
Local digital terrain model (DTM) and orthorectified image (ORI) mosaics over Sakarya Vallis, west of Aeolis Mons in Gale crater, Mars. The two constituent DTMs were processed using the CASP-GO suite described in Tao et al. (2018); the ORIs were processed using Ames Stereo Pipeline. The DTMs were then co-registered to an HRSC DTM mosaic (Persaud et...
Data
Digital terrain model (DTM) mosaic of Gale crater, Mars, processed from High-Resolution Stereo Camera (HRSC) stereo images using the modification of DLR-VICAR described by Kim and Muller (2009).
Conference Paper
Full-text available
There is a pressing need for climate-friendly conferences that are accessible to different people and which can still connect scholars meaningfully. The pressure on virtual conferencing technology in a COVID-19 era, as well as the many years of disabled activism around remote access and virtual meetings, make this an even more important issue. Furt...

Conference Paper
Full-text available
25-cm HiRISE orthorectified images (ORI) and 5-12.5-cm HiRISE super-resolution restored (SRR) products of the Mars Exploration Rover (MER) traverses have been combined with 25-cm shape-from-shading DTMs and visualised in the NASA DERT platform. The SRR and standard resolution ORI images have been compared to evaluate the refinement achieved by supe...
Conference Paper
Full-text available
The Martian surface remains hostile due to a lack of atmosphere, temperature variability, and solar radiation, but its subsurface holds promise for present or ancient astrobiology and future human habitation. The location and characterization of near-surface (< 100 m) ice distributions and lava tube (pyroduct) systems could provide both valuable ge...
Conference Paper
As the closest Earth-like, potentially life-sustaining planet in the solar system, Mars' future of human exploration is more a question of timing than possibility. The Martian surface remains hostile, but its subsurface geology holds promise for present or ancient astrobiology and future habitation, specifically lava tube (pyroduct) systems, whose...
Conference Paper
Stereo topography, combined with models of viscous relaxation of impact craters, allows for the study of the rheology and thermal history of icy satellites. An important step in calculating relaxation of craters is determining the initial depths of craters before viscous relaxation. Two methods for estimating initial crater depths on the icy satell...
