Dear IPNSIG members, As we step into the dawn of a promising New Year, I want to take a moment to reflect on the incredible journey we've had together in the past year and express my heartfelt wishes for 2024. Each member plays a vital role in our shared mission, and we are thrilled to announce some remarkable milestones and exciting initiatives that highlight our collective impact. Thriving Membership Our membership has soared past the 1000 mark and continues to grow steadily. This achievement is a testament to the shared passion and commitment of our members. Your dedication fuels our mission, and we are excited to welcome new voices and perspectives to realize our vision. Let’s grow our vehicle even bigger this year. PWG Project Work The Pilot Projects Working Group (PWG) continues to be one of the most active groups within IPNSIG to mature the DTN technology. Spanning from caves, the Arctic to track reindeer, healthcare in Space, and the ground-based DTN Test network, the PWG has been vital in facilitating DTN in various use cases. All of which are to be future-ready for the Interplanetary Network. Study on Interplanetary Internet Governance The AWG was extremely active, studying the future architectural and governance challenges of the Interplanetary Internet. In case you haven’t seen it yet, here is the IPNSIG published report, authored by the many global leaders from around the world. IPNSIG Academy Monthly Sessions Empowering everyone with a passion for the Interplanetary Internet is one of our core missions. The IPNSIG Academy continues to be a beacon of learning, hosting enlightening sessions every month. Laura Chappell, Ginny Spicer, and Mike Snell led us last year, hosting over 10 sessions inviting global leaders from around the world. Inspiring the Future, the "100 Year Vision" Video We were thrilled to unveil the "100 Year Vision" video, which delivers the expansion of the Interplanetary Internet from Earth to the deep skies, spanning our solar system. This visionary video encapsulates our aspirations, goals, and the outcome of the Interplanetary Internet. We invite you to visit here, if you haven’t seen it yet. Looking back on the DTN history, the “DTN Retrospective" Video The DTN concept has matured since its inception in the late 1990s. The "DTN Retrospective" video, led by Scott Burleigh and Mike Snell, covers our historical milestones and contains footage of how the DTN has matured. Come and visit here to look back on our history. Aside from these activities, the first Space x Internet Summit was held at Interop in collaboration with WIDE in Tokyo, Japan - the first year that Interop highlighted Space, and we were extremely proud to host this event. Ronny Bull, Marius Feldman, Juan Fraire, Oscar Garcia, and Alberto Montilla came on stage to share their developments in DTN. The IPNSIG also presented at the APNIC convention, EuroDig, and many other forums and events to broaden the impact of our important work. Lastly, your active engagement and contributions remain the core of who we are. Let’s do great things together. Happy New Year to everyone. Sincerely, Yosuke Kaneko, President

We’d like to thank Dr. Scott again for his really interesting and engaging presentation about the Consultative Committee for Space Data Systems (CCSDS) DTN Standardization Efforts.

Dear Internauts, Another year has gone by but this one has been particularly productive for the Solar System Internet work of the IPNSIG. I want to acknowledge especially three areas of significant progress: 1. The Project Working Group, led by Oscar Garcia, has been growing in membership and making major progress putting ION and other BPv7 implementations onto new operating system and hardware platforms. Scott Johnson has outfitted BPv7 ION with an IPv6 convergence layer – a major undertaking. Please see Oscar’s PWG report for more information. 2. The digital library has grown dramatically, curated by Laura Chappell working with Scott Burleigh. This is turning into a major reference resource for people interested in the SSI. 3. The Architecture and Governance Working Group (AWG), led by Kaneko, our Chairman, has had substantive discussions aided especially by James Green (former Chief Scientist of NASA) and Scott Pace (former Executive Director of the US National Space Council). We are on the cusp of an exciting re-entry into human and robotic space exploration and commercialization. As we embark on this journey, I cannot help but think about the consequences of the discovery of the Americas in 1492 (not counting Leif Ericsson around 1000 AD!). A new world and new economic development accompanied by a range of conflicting interests. It was not until 1648 that the Peace of Westphalia established principles that still guide international relations today. As we embark on this new journey, as a species, I hope we can put aside conflict and recognize our mutual interests as Earthlings beginning a historic new journey into our Solar System and, someday, perhaps beyond that.

Dear IPNSIG members, As we approach the end of the calendar year, I see that our chapter has been extremely vigorous toward our vision of expanding networking to interplanetary space. If you recall, in 2022, we became the first space chapter, namely the Interplanetary Chapter of the Internet Society, and our work including the ones in progress are being widely noticed in the global community. As we reflect upon ourselves this year, we have witnessed the success of the Artemis1 mission which opened up a new era in space exploration. With the global momentum that is pushing our human boundaries farther into deep space, the need for a communication infrastructure continues to rise. The buildout of the Solar System Internet (SSI) has entered its prologue, and as the Interplanetary Chapter, we continue to seek a common network infrastructure that benefits humanity. In line with our vision, I would like to share some highlights of our achievements in 2022. ● Architecture and Governance Working Group The Architecture and Governance Working Group (AWG) was formed to assess the technical challenges in achieving a common network infrastructure and to explore the possible organizational structure that could support the development, governance and evolution of the SSI. The AWG aims to publicize a report next year for further discussion of our work with the broader international community, so stay tuned for more information. ● Strategy Working Group We have shared the “Strategy toward the Solar System Internet for humanity” report in various forums, including the NASA DTNWG, IPNSIG Academy, Eurodig 2022, STINT WS and at the recent ISOC North America-Caribbean regional call. Our work is being widely noticed and we will continue to broaden our roadmap developments in the following year. ● Projects Working Group The Projects Working Group has developed during the year a Global Network to test the Bundle Protocol Suite with the usage of DTN (Delay and Disruption tolerant networking) for the Interplanetary Internet. This network was deployed with volunteers from 15 countries and several other locations are interested in joining. The PWG DTN network has received interest from Space Agencies, private companies and developers for testing and deploying their applications on the Interplanetary Internet. A technical laboratory for testing the DTN technologies on different hardware was developed by one of our PWG members. PWG members have also tested interoperability between different DTN implementations. Several practical applications using DTN for communications have been developed and can be applied to Space travel and challenged environments on Earth as well, including mobile telephone messaging using DTN, reindeers tracking in the Arctic, environmental protection technologies in underground protected caves and medical records for space exploration. In the area of base communications technology, the PWG members have developed technologies such as IPV6 for ION DTN, ION-DTN Lora-DTN (which is used in very challenged environments) interfaces allowing the development and expansion of this technology for real life applications. Software tools have also been developed for management and operation of the PWG network. As a contribution to the public domain, several documents and open source software have been presented on the mentioned developments with the intention of facilitating the expansion of the DTN technologies for public usage. Public presentations have been performed about our work including presentations and collaboration with Space agencies like NASA, and private companies that are interested in Space travel, and plan to incorporate the DTN technologies to their deployments. You can review several videos about the various conferences in the PWG blog at http://pwg.ipnsig.space For next year 2023, the PWG plans to expand our network to Space as an immediate project. ● Technical Documentation Working Group The Technical Documentation Working Group works quietly, behind the scenes, to collect and organize published documents that can help the student or researcher or interested fan learn more about interplanetary networking. At this time, the IPNSIG Zotero Library – implemented using Zotero software and backed up each month – comprises nearly 300 items, including all IPNSIG Academy talks; all items are tagged with keywords, linked, and filed in virtual folders. In 2023 we will move the library to a new website and we will also be reviewing all of the IPNSIG Academy chat-rooms records, looking for citations of additional resources that need to be in the library. ● Outreach Working Group IPNSIG Outreach Working Group has revitalized itself with a small core team of dynamic members: Laura Chappell, Ginny Spicer and Henry Danielsen. They are already making significant headway. Laura Chappell has developed a forms-based tracking system, using SmartSheet to automate most of the processes necessary to plan, organize and execute IPNSIG Academy Webinars. Thanks, Laura! Ginny Spicer has identified a simpler web development platform for ipnsig.org, that will greatly simplify things for content creators. A real bonus is that this platform has far superior email capabilities compared to our current hosting solution. Ginny will be presenting the new website she has developed for ipnsig.org to the Board in January. Finally, Henry Danielsen has volunteered to develop remote learning content for IPNSIG Academy, providing direct engagement with educators and students, teaching them the basics of DTN. We are really excited to have these great folks on board, and are looking forward to what they will accomplish in 2023. ● IPNSIG Academy IPNSIG launched its IPNSIG Academy events in May of 2022. We have met our goal of producing a webinar each month – a total of eight webinars in 2022. Attendance has been good, with a lot of questions during the Q&A session following each presentation. We have also had a lot of views of our video recordings. You can access the video recordings and presentation materials by using the IPNSIG Zotero library, as mentioned above, or you can check out the IPNSIG Academy Events page on our website. The table there lists past and future IPNSIG Academy webinars, with links to video recordings and presentation materials as they become available. Bigger and better things are planned for IPNSIG Academy in 2023! Not only are we lining up some really great speakers, but we also want to expand IPNSIG Academy to more directly engage the educational community. More details about that in a future newsletter! Lastly, I wish everyone a very merry holiday season and all the best for the New Year. Kaneko IPNSIG President

STINT 2022 Workshops Videos Now Available Videos of this year’s Space-Terrestrial Internetworking Workshops (STINT) included presentations from quite a few IPNSIG members (including our President, Kaneko and Board Members Oscar Garcia and Alberto Montilla). Session videos are available here. A list of the program topics and presenters is available here.

We are glad to share that the IPNSIG Architecture and Governance Working Group (AWG) held a workshop on Routing in Delay and Disruption Tolerant Networking over four days, from August 22 to 25, 2022. The goal of the workshop was to look at the various routing approaches and to produce a recommendation toward realizing a common interplanetary network architecture. During the workshop, the group looked into the following routing approaches: Routing in European Space Agency (ESA) Bundle Protocol (BP) Implementation, presented by Felix Flentge Schedule-Aware Bundle Routing (SABR), also known as Contact Graph Routing (CGR), presented by Scott Burleigh REDMARS Routing, presented by Marius Feldmann and Felix Walter Spacetime Routing, presented by Brian Barritt Shortest-Path Tree Routing for Space Networks (SPSN), presented by Olivier de Jonckere) Opportunistic forwarding approaches – constrained flooding PROPHeT, Spray and Wait, presented by Juan Fraire Opportunistic CGR, presented by Scott Burleigh Inter-Regional Forwarding, presented by Scott Burleigh As a result, AWG has produced the following recommendation: The IPNSIG, as an organization under the Internet Society, advocates the concept of establishing a common, interoperable, autonomous and scalable routing framework within the Solar System Internet. We believe this is crucial to achieving a resilient and sustainable communication environment in space. We express our willingness to facilitate and expect interested communities to further pursue the refinement and advancement of a technical solution in support of this goal. We underline four important aspects for the future of Routing in Solar System Internet: Autonomy The overall goal is to populate forwarding tables or routing tables (where appropriate) without human intervention and depart from the Earth-centric management scheme Commonality To enable Autonomy we need a common and standardized way of the following: The population of a Forwarding and (where routes are computed) Routing Table Function enabling the bundle protocol agent to access a forwarding table API that answers the question: “where should I send this bundle and with what CLA/address?”, similar to ARP lookup Interoperability Define a common to every Node set of functions Interoperability Inter-regional routing should be based on a common standard Intra-regional routing could be heterogeneous, adopting methods that suit the needs of a specific environment or a mission Inter- and Intra-region routing should be interoperable Scalability Architecture needs to be structured in some way (Hierarchy) Node IDs, Addressing Schemes, and segmenting concepts need to be further explored to accommodate the scale of the SSI You can find the summary report here and our recommendations report here.
