From the Chairmen

It is a great pleasure for us, the three chairmen, to invite the international community to the 14th IAA Sympo- sium on Small Satellites for Earth System Observation (SSEO). The Symposium will be hosted by the German Aerospace Center (DLR) and the Technical University of Berlin and be held from May 7th – 12th, 2023 in Berlin. We are especially excited to welcome you to this year’s symposium in person. After the past virtual edition of the Symposium in 2021, it is truly a privilege to be able to bring together many international experts in this booming field of Small Satellites for Earth System Observation.

Small Satellites for Earth System Observation are nowadays a key part of the critical space infrastructure and of high societal relevance. In addition, they provide an important facilitator for the UN Sustainable De- velopment Goals. These types of missions can be conducted efficiently, provide increased opportunities for access to space and help to realize new functionalities and services. The design of such satellites, its bus and payload systems, can cover a wide span, ranging from optimized off-the-shelf systems, with little or no requirements for new technology, to innovative tailored high-tech systems. Thus, new classes of advanced small satellites can be created, including autonomously operated satellites or employing onboard machine- learning algorithms for increased agility or downlink efficiency, which render missions more efficient or open new fields of applications for science, industry, governments or the public. In addition, multi-satellite systems, such as constellations and formations, offer exciting opportunities for a new economy in space, when based on small satellites.

We will build this year’s edition on the success of past IAA Symposia, where authors from more than 35 countries, representing space agencies, industries, knowledge institutes and academia, confirmed in their oral presentations and poster sessions that these missions can be conducted efficiently and offer opportu- nities for new applications and innovative technology. However, we will also implement changes, such as a new venue, the Ludwig-Erhard-Haus, which will provide an inspiring environment, excellently suited to let us explore the latest developments in the field. We have an incredible lineup of speakers, who will share their expertise and insights, including a special session on Onboard Machine Learning for Small Earth Ob- servation Satellites. We encourage students for presenting their work. The IAA is pleased to serve as the principal sponsor of this symposium because its objectives complement and reenforce the purpose of the Academy.

It is a pleasure for DLR’s Institute for Solar-Terrestrial Physics to be the host of this symposium. The young and new institute conducts research in the field of space weather. It complements and expands the research portfolio with essential components and strengthens Germany’s position in the scientific community. DLR’s east German sites have been successfully involved in space research for many years. Together with other relevant institutes of DLR, it is now part of many national and international projects for Earth Observation, planetary sciences, technology development and in-orbit verification. The Technical University of Berlin is pleased to be the co-host of the 14th Symposium. The Chair of Space Systems has already brought into space 27 satellites for Earth Observation, satellite communication, and technology demonstration, which were designed, built, and operated by students. Another 6 small satellite missions in development underline TU Berlin’s position at the forefront of academic research and innovation.

We are convinced that the personal interactions, shared experiences, and exchange of ideas are the heart of this Symposium and make it so valuable. Thus, we are looking forward to meeting you in Berlin in May 2023.
