Special Issue Information
Dear Colleagues,
Space situational awareness (SSA)—to detect, track, identify, and characterise resident space objects (RSOs)–has been recognised in the research community as one of the top priorities for space activities in Canada. Damage to space systems has a significant and immediate impact on the technologies we all rely on daily, including navigation, communication, resource management, climate monitoring, and severe weather forecasting. According to NASA, there are more than 22,000 objects that are larger than 10 cm in diameter orbiting today, with a total number of 500,000 under 10 cm; only 86% of the objects have been identified. The remaining 14% are uncatalogued and unidentified objects (such as debris) that pose threats to space assets like the International Space Station. SSA brings attention to the infrastructures of space that are increasingly central to our earthly existence and sites of concern for the future. As such, it is imperative to enhance the technologies and further develop the capabilities that identify both active satellites and debris.To meet the growing demand for SSA missions, several sensor technologies have been proposed to be suitable for both ground-based and space-based object imaging including SWIR, neuromorphic cameras, wide FOV cameras, and more. This Special Issue is dedicated to featuring innovative and cutting-edge sensor technologies for SSA applications.

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. Sensors 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 2600 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.
