New IPNSIG Logo!!

IPNSIG Logo starfield

IPNSIG member Juan Fraire has crafted an excellent set of new logos for IPNSIG. We will be increasingly incorporating these into our website and communications. Members of the IPNSIG board met with Juan repeatedly over the past couple of months to discuss the logo and review iterations. We’re really pleased with the results, and we trust you will be pleased also. Various versions of the logo are shown below.


In the words of the designer:

This logo intends to express the shape of concentric circular orbits accompanied by stars on the background. Orbital paths are discontinuous, to transmit the feeling of disruption, a natural feature of interplanetary networking. Color codes are lighter at the center mimicking sun/star light. Notice the logo works on clear/dark backgrounds (i.e., paper, space flyers, publicity, etc.) and plain black/ white versions are adequate for monochrome printing

Thanks so much to Juan for his work!

New Year Message 2021

New Year Message


IMG-9727Happy New Year!

I hope you all were able to spend some time with your family and friends over the New Year holidays.

Please allow me to address a few words on the ongoing activities of IPNSIG.

Last year, amid COVID-19, I came to realize that the Internet is literally an essential foundation for our lives, supporting social and economic activities. The Internet has sustained and also enriched our normal daily lives connecting everyone and everything together—even under this unprecedented global crisis.

When we look at the goals of IPNSIG, they present a bold mission for humanity, which is to extend terrestrial networking to space.  The InterPlanetary Network (IPN) will allow people and missions to interconnect, enabling humans to expand their social and economic sphere farther into the solar system.  I believe IPN will become an essential human asset there, just as we have seen with the internet today.

After I assumed the chair last year, five working groups were defined to broaden the impact of IPNSIG, and some have already started their activities.

This year, we will be sharing and discussing the working group products with the membership, and my hope is that IPNSIG as a whole could deliver this shared vision of IPN to the entire world.

I’m really looking forward to our active discussions as we march forward.  I believe we can become a leading initiative of making IPN a reality.

Wishing you all a year full of blessings and filled with new adventures.

Let’s all stay safe.

connecting clouds with DTN

Historical feat connecting clouds with DTN by IPNSIG members


On Friday, November 27, 2020, Oscar Garcia, Board Member of IPNSIG and developer of the Medical Records System for Space Exploration, and Dr. Larissa Suzuki, Data/AI Practice Lead of United Kingdom and Ireland at Google, DTN expert at Google and member of IPNSIG, made the first DTN-enabled interconnection between servers in the Google and Amazon cloud services.


The first message between the servers was the salutation and response between Mr. Garcia and Dr. Suzuki sent at 5:36 PM UTC (Universal Standard TIme), 12:36 EST. This development, sponsored by IPNSIG, and inspired by Vinton Cerf, Board Member of IPNSIG and one of the Fathers of the Internet, was  technically advised by Scott Burleigh, from NASA/JPL and developer of the ION implementation of the DTN Bundle Protocol currently used in the International Space Station, and was supported by Michael Snell, past  IPNSIG President and currently Secretary/Treasurer.


This achievement was the product of several months of development in applying the Interplanetary Bundle Protocol to demonstrate the use of DTN techniques to interconnect existing terrestrial systems.  Several applications are in development between IPNSIG members and other groups for the utilization of the Bundle Protocol for situations like first responders, medical records, e-commerce and others for conditions where regular Internet connectivity is not permanently available or stable.

Member article on LunaNet

Member article on LunaNet

LunaNetIPNSIG Board member Dr. Alberto Montilla has published on article on LinkedIn about NASA’s plans for LunaNet: an Internet infrastructure to support lunar exploration as mankind returns to the surface of the moon–  as early as 2024!

Dr. Montilla explanains NASA’s plans for an Internet infrastructure on the moon supporting Positioning, Navigation and Timing (PNT) services, Science data and Detection as well as other services. Of course, DTN’s will play a key role in that infrastructure. Planned throughput capacity is quite large, enough to accommodate several simultaneous video streams. The full article is available here: Discover how LunaNet is a critical step in building out the InterPlanetary Network.


Strategy Work Group Members Announced

We are pleased to announce the membership of our Strategy Work Group:

Work Group Lead:  Yosuke Kaneko

Work Group Sub-Lead:  Kiyohisa Suzuki

Work Group Members:   Vint Cerf, Scott Burleigh, Maria Luque

We will plan for a kick-off meeting of the Work Group soon. Dates, time will be proposed later.

Congratulations once again and we look forward to working with all of the Work Group members!

Best Regards,

Kaneko, IPNSIG Chair

IPNSIG Roadmap and Working Groups

With inputs from the Board, our Chairman, Kaneko, has developed a long term roadmap document for IPNSIG. He has laid out an exciting (and challenging) strategic vision for InterPlanetary Networking and IPNSIG’s role in realizing that dream. The IPNSIG Roadmap document (“Creating a Sustainable IPN”) can be accessed Here.

As announced earlier, the SIG will be launching a few Working Groups (WGs) to support the strategic vision laid out in the Roadmap Document.  At this time we will be calling for participation in the SWG (Strategy Working Group).
Please find more details in the link below.  Let us know if you are interested in signing up by sending an email to Please get your emails in by COB Friday, November 6th,2020.

CCSDS has updated its public-facing website

The Consultative Committee for Space Data Systems (CCSDS) has completely revamped its public website. Check it out at:

CCSDS is the global standards setting organization for civilian space flight. They have published standards for a number of DTN protocols, including the CCSDS Bundle Protocol Specification and the Licklider Transmission Protocol (LTP) for CCSDS. More than 1000 space missions have chosen to fly with CCSDS-developed standards.

dtn-single-hopNASA has recently published a new Delay & Disruption Tolerant Networking (DTN) web page. This page provides a great overview of DTN: what problems it solves in space communications, a high-level explanation of how it works, and a short summary of the benefits it delivers for space missions.

The page also has links to: 1) NASA resources for space mission development using DTN; 2) a page describing the future of DTN—standardization work in progress with CCSDS and IETF as well as future planned space missions that will use DTN and 3) a very nice newest-to-oldest list of DTN historical milestones. Check it out at:

One final note—the new DTN page was also added to the Technology and Engineering landing page:
