If you are asked what the biggest barriers to future space transportation development are, what do you list?
The fact is, whereas airframe loss rates are in the order of one per 10 million, space flights have remained high, in the order of one per cent during the past 40 years. The system safety and reliability of space transportation have been improved by enhancing system redundancy, reducing the failure rate of onboard equipment, and strict quality control. However, these statistics imply that these methods are already at their limit. It is essential for space transportation to acquire drastic resilience against hazards in order to demonstrate safety and reliability comparable with those of air transportation. I hope to develop a hybrid rocket that can be an essentially non-explosive propulsion system, as a means to improve the resilience of space transportation in the future.
Aerospace’s Special Issue “Advances in Hybrid Rocket Technology and Related Analysis Methodologies” was edited by Dr. Carmine Carmicino, in which fourteen open-access papers (10 articles, three reviews and one editorial) were published between 6 March 2019 and 13 May 2020. This resulted in the publication of the latest technical articles and informative technical reviews from all aspects of hybrid rockets. I think this second edition will be of great value as it follows the previous one in continuously updating the technical information and further extends itself to new technical fields. Here, I would like to welcome Dr. Arif Karabeyoglu and Dr. Carmine Carmicino as co-editors to organize the contents of this edition and ensure that they are broader and more attractive.
Soon, the hybrid rocket engine from Virgin Galactic SpaceShipTwo will be put to practical use in space travel. There is no doubt that the technology of hybrid rockets will be improved with the aim of safer manned space flights. This means that investment in technological research will or shall occur. This edition deals, as well as with advances in hybrid rocket technology and related analysis methodologies dealt with previously, with novel space transportation systems, mission concepts and optimization using hybrid rockets. I would also welcome articles that deal with how we can deepen the involvement of hybrid rockets, as well as technical papers dealing with other aspects of hybrid rockets, such as CFD, internal ballistics, combustion instabilities, propellant performance. Additonally, since quite a bit of activity on hybrid flight systems around the world is going on, so topics on such systems and more practical aspects of hybrid rocket based systems can be also included.

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.
