Special Issue Information

Dear Colleagues,

Recent developments in space instruments and sensing technology have significantly enhanced our ability to explore and monitor the Earth’s environment as well as deep space. New developments in sensor design and space instrumentation, including miniaturization, lightweight design, and improved robustness, have made it possible to deploy high-precision instruments and sensors in the harsh environment of space. Designs in space can cover a broad pallete of different aspects and applications.

Researchers are encouraged to submit their latest findings and results as full-length articles or reviews. Targeted topics include, but are not limited to, advancements in spaceborne sensors, novel space instruments, sensing techniques for Earth and/or deep-space observations, telecommunication setups used for Earth–space links and/or intersatellite links, hyper- and multispectral imaging, astronomical observation, and telescopes.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Applied Sciences is an international peer-reviewed open access semimonthly 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.

We propose a Multispectral Earth Polarization Imager (MEPI), which is located at the Earth–Moon system’s Lagrange point L1. The imager can be used to measure the sunlight reflected by the Earth and the Moon. The measured sunlight has specific polarization information and spectral information, which can provide strong support for a comprehensive understanding of the Earth system and the construction of a perfect Earth–Moon system model. The MEPI provides multispectral images with wavelengths of 400–885 nm, and uses four sub-aperture systems to share a main system. The imager can capture the two-dimensional shape and polarization spectral information of the entire Earth at a spatial resolution of 10 km, and all spectral images can be simultaneously acquired on a single detector. The optical system of the instrument was designed and simulated. The simulation and analysis results showed that the camera can obtain high-quality images of the Earth disc with a 2.5° field of view (FOV). The novel MEPI provides a new way to generate climate-related knowledge from the perspective of global Earth observation. The imager can also be used for lunar observation to obtain spectral polarization information on the lunar surface. In addition, it also shows great potential in other applications of space remote sensing spectral imaging. Full article

This paper presents the design, implementation, and testing of an automated sieve system tailored for lunar regolith sorting to support ISRU applications, specifically targeting particles of 500 μm size. The design incorporates an approach to mitigate sieve blocking, crucial for effective regolith particle separation, utilizing natural frequencies and adjustable sieve angles. The results indicate the system’s effectiveness in separating regolith simulant fractions, with notable variations in sieving efficiency and sieve blocking observed based on sieve angles, simulant types, and aperture sizes. Further investigations include evaluating the influence of amplitude and moisture content on sieving efficiency and analyzing sieve blocking tendencies. Despite variations in simulant behavior and operational parameters, the prototype demonstrates promising performance, characterized by tight confidence intervals in measured results. Full article
