The International Day of Human Space Flight commemorates the first manned space flight by the Soviet citizen Yuri Gagarin on 12 April 1961. This day was declared the International Day of Human Space Flight in 2011 by the United Nations General Assembly resolution, to celebrate the beginning of the human space age. It reaffirms the important contribution of space science and technology in achieving sustainable development goals and increasing the well-being of countries and people, as well as ensuring the realization of their aspiration to preserve outer space for peaceful purposes. 

In the course of human exploration of space, we have established many remarkable achievements and breakthrough milestones:

• In 1957, the first human-made Earth satellite, Sputnik I, was launched into outer space;
• In 1961, Yuri Gagarin became the first person to orbit the Earth;
• In 1969, Neil Armstrong became the first human to set foot upon the surface of the Moon;
• In 1996, the first spacecraft in human history successfully landed on Mars;
• In 1998, the International Space Station, a 16-nation international space program, launched for the first time;
• In 2009, the Kepler space telescope was launched, which has helped humans find thousands of exoplanets;
• In 2015, SpaceX successfully launched its Falcon 9 rocket and recovered the first stage. 

To further explore the information about space on the 2023 International Day of Human Space Flight, we have gathered academic research from several journals on the topic of space flight, all of which are open access, enabling practitioners, policymakers and people around the world to access and share up-to-date scientific knowledge. 

Let us celebrate the International Day of Human Space Flight together.

On Tuesday, 25 April 2023, MDPI and the journals Remote Sensing, Drones, Land and IJGI organized the webinar entitled EO&GEO Series: New Milestones in Drones—from New Drones Designs to Real-Time and Artificial Intelligence Applications.

It is clear that drones have become an increasingly popular tool for mapping and surveying, with their ability to capture high-resolution and multi-sensor imagery. However, traditional mapping techniques often require significant time and effort to process the collected data before it can be used; therefore, real-time drone mapping offers a game-changing solution that is going to transform various application fields, such as emergency response or agriculture. 

Thanks to our recognized speakers, we had the opportunity to share with the audience novel insights into drone technology, from real-time mapping applications and novel drone designs to close to market vertical solutions in agriculture.

Please note that this webinar is associated with the Topic titled “Advances in Earth Observation and Geosciences”.  The deadline is 31 December 2023.

We are pleased to announce that Dr. Pablo Rodríguez-Gonzálvez has been appointed Editor-in-Chief of the Section “Innovative Urban Mobility” in Drones (ISSN: 2504-446X).

Dr. Pablo Rodríguez Gonzálvez is a surveyor (2004), a geodesist and a cartographer (2006), who obtained his Ph.D. in 2011 and worked at the University of Salamanca, Spain, for 8 years, joined the University of León, Spain, in 2017, and continues to be an Associate Professor in the Geomatics field. His research career is supported not only by the publication of articles in scientific journals, communications in international conferences, book chapters, and edition of books, but also by university‒business knowledge transfer, in the form of projects, patents, and software development related to the application of Geomatics in different disciplines. Furthermore, his participation in multiple R&D projects at international levels, all of them related to Geomatics, are noteworthy. As a result, his research has been awarded at the national level by different institutions. His primary research field is the application of Geomatics techniques, mainly photogrammetry and laser scanner, 3D modeling, and radiometric analyses. These lines of research led him to collaborate in multiple fields, including industrial engineering, cultural heritage, and forest management. He has been a member of the National Management Committee of COST Action CA16219 (“Harmonization of UAS techniques for agricultural and natural ecosystems monitoring”), from 2017 to 2022, and an Editorial Board Member of Drones since 2017.

The following is a short Q&A with Dr. Pablo Rodríguez-Gonzálvez, who shared his vision for the Section with us as well as his views on the research area:

I have been involved in the journal Drones since its foundation, and during this journey, I found it a fulfilling experience, not only in the interaction with colleagues during the peer-review process but also with the publisher during the editorial process.

In my new role as a Section Editor-in-Chief, I intend to help the journal to increase the visibility of new trends related to drones, emphasizing autonomous vehicles and their relationship with urban mobility and smart cities. In addition, I will also be involved in the continuous improvement of the journal’s quality.

With this new Section, I expect to help the journal to continue its growth in terms of the number of articles and their quality, while addressing innovative topics.

Drones are a key element in the development of the new paradigm of urban mobility, as well as the transportation of passengers and goods. However, we are at a very early stage where we must overcome several challenges before the complete adoption of this new paradigm. In this line, researchers from universities, administrations, and companies are being very active, so new findings and advances are expected in the following years on this topic.

Open Access improves the visibility, accessibility, and impact of research work on other colleagues, the university community, and society in general. Moreover, it favors the authors’ recognition and improves the positioning of their work. Therefore, I consider it to be the future of science.

All researchers involved in drone, aerial or terrestrial research with cutting-edge, interdisciplinary research and/or innovative trends are welcome.

We warmly welcome Dr. Pablo Rodríguez-Gonzálvez as the Section Editor-in-Chief of “Innovative Urban Mobility”, and we look forward to achieving many milestones under his leadership.
