2023 New Year Message

2023 New year message from Kaneko


Happy New year to you all.

2022 has been a remarkable Year of milestones for us – we became the first Space Chapter within ISOC and launched new Working Groups to explore Architecture and Governance of the Solar System Internet (SSI). We also setup the IPNSIG Academy to offer a learning venue sharing our 100 year vision and introducing attendees to the key technologies organizations developing, testing and standardizing Delay & Disruption Tolerant Networking (DTN). Finally, recently we surpassed 900+ members!

There is so much energy and passion within our group. Let’s keep it going in 2023!

This year, I envision 3 areas to work towards:

No.1 Publicize the work of the Architecture and Governance Working Group more broadly; and more particularly, communicating it to the broader international community.

No.2 Promote Pilot Projects to refine the DTN/BP technology and work towards implementing it in both real space projects and terrestrial applications.

No.3 Enhance the IPNSIG Academy (more details to come later) to provide more direct engagement for educators and students. Our commitment to engaging younger generations to the vision and opportunity of the Solar System Internet continues!

I believe that demonstrating humanity’s ability to collaborate successfully in Space will give hope that many issues confronting mankind on Earth can also be overcome through global collaboration. As the Interplanetary Chapter, I would like us all to work toward an accessible, open and trustworthy SSI that benefits humanity. We can do that by sharing our vision and the value it creates and even directly contribute to the development & evolution of the SSI.

One final note: we want IPNSIG to be an organization that respects and values inputs from everyone. We want to make sure that all of our communications reflect that. As members of the Internet Society (remember that IPNSIG is also the Interplanetary Chapter of the Internet Society) we are all bound to comply with ISOC’s Code of Conduct for members. They can be found here:

             2019 Document (This was specifically intended to address discussion group behavior)

 2003 Document (This earlier, more comprehensive document is broader in scope, covering all communications)

 ISOC informs us that they are in the process of consolidating the two documents into one CoC version, but for the time being, both are in effect. Please take a few minutes to familiarize yourselves with these expectations.

Wishing everybody a peaceful, happy, healthy, and successful 2023.

December IPNSIG Newsletter

IPNSIG 2022 summary

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

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, 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 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.

Year End Message from Vint Cerf

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.
