Register for June IPNSIG Academy Keynote

 IPNSIG Keynote: Doreen Bogdan on ITU Governance and Prospects on SSI


Date & Time: Jun 28, 2023 7:00 AM–8:00 AM Pacific Time (US and Canada)




The International Telecommunication Union (ITU) has been a key player in space communications since the beginning of the space era. ITU Secretary-General  Doreen Bogdan-Martin will join Vint Cerf for a fireside chat exploring space’s potential as a driver of sustainable development. They will discuss promising opportunities in the space economy, striving for “Space for All,” and balancing space-based benefits with risk management to ensure space sustainability. Bogdan-Martin will share insights from ITU’s extensive experience managing the international treaty governing global radio-frequency spectrum and satellite orbit management. 

Doreen Bogdan-Martin took office as Secretary-General of the International Telecommunication Union (ITU) on 1 January 2023. Ms Bogdan-Martin has held leadership positions in the field of international telecommunications policy for over two decades, with a track-record of brokering innovative partnerships to expand digital inclusion and connectivity for everyone around the world. Following her historic election by ITU Member States in September 2022, she became the first woman ever to head the organization, which was first established in 1865 and became a UN specialized agency in 1947.

AWG Conference Coming May 30th

IPNSIG will be hosting a workshop to discuss Architecture and Governance of the Interplanetary Network.

As we look around the globe, we are witnessing a significant thrust in space exploration. We are on the cusp of an exciting re-entry into human and robotic space exploration and commercialization, and the deployment of an Interplanetary Network is the key to enable such efforts.  

Today, there are several initiatives including the Government, Space Agencies and the private sector that expand communication capabilities off the planet, to the Moon, Mars and beyond.  Such capabilities will provide significant opportunities to  explore, gain new knowledge, and expand more businesses in Space. They all bring benefit back to Earth.

As the venture of expanding the Interplanetary Network are remarkable steps for humanity, it is also the time to discuss how a “Common Interplanetary Network Infrastructure” could be realized, which entails the need of Governance – a management structure to support the operation of the infrastructure itself.

The Architecture and Governance Working Group (AWG) has tackled these important subjects by reflecting on the lessons learned from the Internet’s evolution and from the remarkable insights provided by our past Academy speakers.

We are happy to share our progress within AWG and are looking forward to some lively discussions. We hope to see you all soon!

More information, including a speaker bio and photo page will be published soon.

Announcements for April, 2023

Important Announcements for April

1)     The IPNSIG Academy presentation, “Architecture and Governance of IPN Conference”, originally planned for April has been postponed to no earlier than May 5th, 2023.

2)     IPNSIG member Juan Fraire submitted the winning proposal and demonstration video illustrating our 100 year vision for a Solar System Internet. He will be working with Board members to refine the concept of the video and agree upon any finishing elements to be added. Thanks much to Juan for this work product. The video will be published when completed and reviewed
by the full Board.

3)     We want to draw your attention to a video of a conference presented by the Universities Space Research Association and the
Space Policy Institute of George Washington University. The theme of the conference was “Cis-Lunar Space: Research for Today, Training for Tomorrow”. It included sections presented by NASA, private industry and academia. Our own Vint Cerf participated in a panel discussion about the challenges and opportunities for commercialization of cis-lunar space. His presentation focused on the complexities of the policy, jurisdiction and governance space for the Solar System Internet. Vint’s talk starts at 3:34:00 in the video.     We found this to be a pretty comprehensive look at NASA’s plans for space exploration and exploitation of cis-lunar space with ties to Martian exploration. The work underway and being planned by the space industry was really encouraging. Very engaging stuff, and worth a look. The video can be found at: https://www.youtube.com/watch?v=-ZF66gZFNJM&t=4s  

Register Now for the IPNSIG Academy March Webinar

Just a reminder to register now for the March Interplanetary Networking Special Interest Group (IPNSIG) Academy Keynote event!

When humans last visited the lunar surface, the internet did not exist and all communications and navigation functions were under the control of a single country (the United States).

This presentation briefly covers primary governance issues, from numbering conventions and spectrum allocations to time standards and domain definitions. The issues are broader than those covered by the Internet Engineering Task Force, and  builders of the interplanetary internet will have to navigate among multiple organizations, including the United Nations, and  Artemis Accord signatories. There are no fundamental barriers, but it is important to think about governance issues early so as  to prioritize technical and political resources while avoiding delays and unnecessary frictions.

Dr. Pace currently serves as Director of the Space Policy Institute, Director of the Institute for International Science and Technology Policy and Director of the MA International Science and Technology Policy program at the George Washington  University’s Elliott School of International Affairs.

We invite you to join us for this exciting Keynote event.

Date: March 1, 2023

Time: 1700 – 1800 Eastern (US & Canada)

The webinar is free but you must register to attend. Register here.

Speaker Bio for January IPNSIG Academy Webinar

Your Speaker: Dr. Keith Scott worked for NASA Jet Propulsion Laboratory from 1997-1998, where he used ACTS mobile terminal data to characterize the effects of Ka-band satellite channels on TCP and SCPS-TP performance. Since joining The MITRE Corporation in 1998, Keith has worked on a number of projects for NASA and the DoD concerning communications in stressed environments including satellite and tactical data networks. He began working on the Interplanetary Internet in 1998, implemented a precursor to the current Bundle Protocol, and is co-author of RFC5050. Keith currently serves as chair of the Space Internetworking Systems Delay Tolerant Networking Working Group in the Consultative Committee for Space Data Systems that is standardizing DTN protocols for use in civilian space missions. Keith is also a member of the Internet Research Task Force and Internet Engineering Task Force’s Delay Tolerant Networking working groups.

Your Moderator: Scott Burleigh recently retired from a position as Principal Engineer at the Jet Propulsion Laboratory, California Institute of Technology, where he had been developing flight mission software since 1986. A founding member of the Delay-Tolerant Networking (DTN) Research Group of the Internet Research Task Force, Mr. Burleigh was a co-author of the DTN Architecture definition (Internet RFC 4838). He also co-authored the specification for version 6 of the DTN Bundle Protocol (BP, Internet RFC 5050), supporting automated data forwarding through a network of intermittently connected nodes, and is now lead author for the specification for BP version 7. Mr. Burleigh led the development and maintenance of implementations of BP and related protocols that are designed for integration into deep space mission flight software, with the long-term goal of enabling deployment of a delay-tolerant Solar System Internet. Mr. Burleigh has received the NASA Exceptional Engineering Achievement Medal and four NASA Space Act Board Awards for his work on the design and implementation of these communication protocols
