Special Issue Information

Dear Colleagues,

With the increasing accessibility of launches, space instrumentation is developing at a rapid pace. This Special Issue aims to highlight recent advances in space optical instrumentation across all types of applications. We are particularly interested in contributions on the latest optical payload developments, novel optical components (free-space or integrated), and optical systems that make Earth Observation and communication more precise and accessible. Contributions on instruments pointing to Earth, other satellites, or deep-space targets are all welcome.

Original research contributions are welcome in the following areas:

  • In-orbit systems, developments, or mission proposals, including the following:
    • Earth Observation payloads;
    • Free-space optical communication terminals;
    • Broadband exploration of the Solar System;
    • Space telescopes for astronomy;
    • Nanosat/CubeSat/Small Sat instrumentation;
    • Adaptive and active optics;
    • Deployable telescopes;
    • Payloads such as spectrometers, imagers, coronagraphs, magnetographs, and polarimeters;
    • Rovers;
    • Plasma and particle sensors;
    • Challenges, current limitations, and strategies to overcome them.
  • Optical ground support equipment, calibration, assembly, integration, and testing.
  • Novel optical components and manufacturing/testing processes, including (but not limited to) the following:
    • Freeform optics;
    • Metalenses;
    • Atmospheric dispersion compensators;
    • Diffraction gratings;
    • New materials;
    • Diffractive optical elements.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Aerospace is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

In this paper the design, modelling, and performance assessment of a miniaturised dual-purpose optical instrument for small satellites are presented. The instrument can function as a star tracker and as a space-debris detection camera. The system integrates commercial off-the-shelf components, i.e., a CMOS sensor, a processing unit and lens assembly, together with a custom three-vane optical baffle optimised for stray-light suppression. A complete numerical evaluation was conducted through optical ray-tracing, lumped-parameter thermal modelling, and structural finite-element analysis to validate the instrument prior to hardware testing. Optical simulations confirmed effective stray-light suppression and acceptable Point Source Transmission behaviour, enabling signal-to-noise ratio performance suitable for star and debris detection up to ∼5.8 mag. The resulting instrument, with a mass of approximately 172 g and dimensions of 105 mm × 52 mm × 52 mm, demonstrates a compact, low-cost, and multifunctional solution for small-sized platforms. Future work includes environmental testing and on-orbit demonstration to prepare the system for flight qualification. Full article
