Innovations in Space Robotics: Pioneering the Future of Space Exploration

Dear Colleagues,

Recent advancements in space robotics have enabled the successful deployment of both on-orbit servicing systems and planetary surface exploration robots. Notably, the U.S. Mission Extension Vehicles (MEV-1 and MEV-2) have demonstrated the ability to dock with and extend the operational lifespans of aging satellites, marking a significant milestone in autonomous orbital maintenance. In parallel, China’s Zhurong Mars rover and the Chang’e-6 lunar mission represent landmark achievements in planetary exploration, showcasing robust mobility, autonomous navigation, and sample return capabilities in complex and unstructured extraterrestrial terrains.

As humanity ventures further into deep space, a new set of challenges emerges, including prolonged mission durations, harsh and unpredictable environments, limited communication opportunities, and the increasing need for high-level autonomy. To address these challenges innovative solutions that enhance the autonomy, adaptability, and reliability of robotic systems are required.

This Special Issue aims to bring together cutting-edge research that tackles these pressing issues in space robotics. We welcome interdisciplinary contributions that span theoretical modeling, system-level design, and experimental validation, with the goal of advancing the technological foundations for sustainable and intelligent space exploration.

We particularly welcome submissions in the following two domains (not exclusively):

1. On-Orbit Servicing Robotics

• Dexterous manipulation mechanisms and robotic arm design;
• Satellite capture, docking, and repair systems;
• Modular and reconfigurable docking interfaces;
• Perception, localization, and motion planning algorithms;
• Ground verification technologies.

2. Planetary Surface Exploration Robotics

• Terrain-adaptive mobility mechanisms, including suspension systems and wheel–leg hybrids;
• Motion planning and control;
• Autonomous navigation under uncertainty;
• Trajectory tracking and locomotion strategies on the Moon, Mars, and small celestial bodies.

We encourage original research that integrates novel methodologies across mechanical design, control theory, artificial intelligence, and system integration, particularly those validated through hardware-in-the-loop or full-physical simulations.

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. 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.
