Release list
CRAN Patch Release 1.0.1
Patch release addressing the Authors@R NOTE flagged by CRAN's automated check service against v1.0.0. No user-facing API changes.
Fixes
- DESCRIPTION: replaced the non-standard
structure("...", .Names = "ORCID")call inAuthors@Rwith the CRAN-allowedc(ORCID = "...")form, which also resolved the downstream Author/Maintainer field mismatch reported on r-devel-linux-x86_64-debian-gcc (#38). - README: replaced a ScienceDirect publisher URL with a DOI (
10.1016/j.asr.2023.04.004) to satisfy CRAN's URL/DOI policy (#39).
Documentation
- Added an "Old School Cool" section to
README.mdpointing readers to more recent Mars solar radiation models for use cases beyond first-order estimates: Kerr et al. (2023), Vicente-Retortillo et al. (2015), and Spiga et al. (2008). The Appelbaum formulas the package implements remain useful for educational purposes and quick trade studies (#38).
Known issues
- One platform (r-devel-linux-x86_64-debian-gcc) reports a WARN on PDF manual generation. Tracked in #40 for resolution before the next release.

Initial CRAN Release
This package calculates solar irradiance (instantaneous power) and insolation (energy over time) on the Martian surface for both horizontal and inclined surfaces. It is based on NASA Technical Memoranda 102299, 103623, 105216, 106321, and 106700, i.e. the canonical Mars solar radiation papers.
Development History
The marsrad package was originally developed between May 2019 and February 2020 as part of two research projects:
Labrèche, G. (2020). "Exploiting the SherpaTT Rover Active Suspension System to Enable Optimal Solar Array Inclination and Orientation for Long Traverses in a Martian Environment." Master's Thesis, Luleå University of Technology, March 2020. https://www.diva-portal.org/smash/record.jsf?pid=diva2:1413245
And:
Labrèche, Georges and Cordes, Florian. (2020). "Using a Rover's Active Suspension System as a 2-Axis Solar Tracker Mechanism." 15th International Symposium on Artificial Intelligence, Robotics and Automation in Space (i-SAIRAS '20), October 2020. https://www.hou.usra.edu/meetings/isairas2020fullpapers/pdf/5035.pdf
This v1.0.0 release represents the package's documentation, testing, and polish for CRAN submission (November 2025).
