Come to this page for all the latest IPNSIG news, and news about Interplanetary Networking in general. In fact, if you come across something you thing would interest the broader community drop a line to newsworthy@ipnsig.org. We’ll review it at our Tuesday morning tag-up call, and if our group of SME’s agree, we’ll post it here… giving you credit, of course, for bringing it to our attention.

This meeting (and upcoming ones) are our opportunity to express the requirements / needs of the space community to IETF as they evolve the commercial DTN standards. The Consultative Committee for Space Data Systems (CCSDS) often seeks to profile the commercial standards for use in space and strives for interoperability with them. Ensuring that the IETF standards can accommodate the needs of the space community is critical to advancing the status and interoperability of the systems that will form the Solar System Internet (SSI).

IPNSIG Library Announcement 

Ginny Spicer, IPNSIG Technical Documentation Working Group Member

Part of the IPNSIG’s mission to expand networking to interplanetary space is to promote DTN technology and facilitate its maturation. It is this mission that has led the IPNSIG Technical Documentation Working Group (TDWG) to create a technical documentation library. We are pleased to announce the IPNSIG Library and share it with you for perusal, research, and inspiration. I recently spoke to two of our IPNSIG board members, Vint Cerf and Scott Burleigh (Technical Documentation Working Group Lead), about the reasoning behind this library and the vision for its future.

Visit the IPNSIG Library here: https://www.zotero.org/groups/2726293/ipnsig_technical_documentation_working_group_ipnsig_td_wg/collections/Z9DUXUY8 

This project advances access to relevant technical information for everyone involved in interplanetary or terrestrial DTN. We have gathered references to journal articles, conference papers, video presentations, books, blog posts, and more. From ant colony optimization to the ZebraNet, resources are searchable, organized, tagged, and given proper attribution. 

The library is hosted in Zotero™, which enables you to easily locate items of interest, generate citations, and copy sections of the library to your own reference manager. 

The IPNSIG Library currently has over 200 items related to the interplanetary networking initiative, the Solar System Internet, DTN security, and DTN protocol implementations. Resources include complete descriptions, language codes, and tags to help you find useful and relevant information easily. 

As new DTN research and implementations occur, we will add references to their documentation to the library so that everyone can benefit. If you find a new resource to add to the IPNSIG Library, please email the resource link to library@ipnsig.org.

Come browse through the library to learn about the future of the Interplanetary Internet and some of the incredible uses of DTN. 

September Newsletter

Dear IPNSIG members,

Since I assumed chair last year, many vigorous activities have been undertaken at IPNSIG, propelling our efforts even further to expand networking to space.

Just one year ago, I felt a need to lay out a narrative and some strategic efforts to be assessed toward establishing an interplanetary network.  That was high on my agenda.  After several intense discussions at the Strategy Working Group and at our engaging workshop held February 2021, IPNSIG has successfully published a strategic roadmap in the form of a Strategy Report .

Today, the report has been shared with the leaderships of the space agencies and private entities across the globe. IPNSIG has also offered to participate in an assembly to further refine the concept of the strategy together, working to shape the future of an interplanetary network.

In light of these exciting events, I am delighted to share that the board recently adopted a new VISION and MISSION STATEMENT to articulate our goals and roles in the development of our endeavors.

The other good news is that we are progressing to become the first space chapter at ISOC and at the same time, the plan is for IPNSIG to file as a U.S. 501(c)3 non-profit organization operating in the State of California.

Your engagement with our mission continues to make a difference. Your passion, expertise, and contributions are all the impetus that brings us closer to realizing our new vision.

So please, let us know of your interests, comments or feedback by sending email to secretariat@ipnsig.org. We will always be happy to address them.

Your voice makes a difference. Let’s make our journey even more exciting.
