The dream of a Solar System Internet is closer than ever.

Our Vision

Expand networking to interplanetary space,
for the benefit of humanity


For over twenty-five years, IPNSIG has been working to realize the dream of networking at interplanetary distances.

Vint Cerf, Adrian Hooke and others at the Jet Propulsion and elsewhere tackled the problem of how to successfully cope with the delay, disruption, and other networking constraints created by the great distances and the very environment of space. The result was a series of experimental protocols– what became known as Delay & Disruption Tolerant Networking (DTN), including the Bundle Protocol.

Many of the pioneers in this work are still members of IPNSIG. And the technical work, while not complete, has matured greatly. Many of the protocols have been formerly adopted by the Consultative Committee for Space Data Systems (CCSDS), a global standards setting organization for civilian space flight. Moreover, a Standards Working Group has been formed within the Internet Engineering Task Force (IETF). Formal adoption of DTN as a set of terrestrial Internet standards is in progress.

Now seems the appropriate time to expand our focus to include both the infrastructure (the Solar System Internet) and the governance of that infrastructure. Especially as commercialization of space progresses, the need for a similar Space Internet that is open, trusted and trustworthy are challenges that must be addressed.

President Yosuke Kaneko

Yosuke Kaneko currently serves as the President of the Interplanetary Networking Special Interest Group (IPNSIG) of the Internet Society (ISOC), an international non-profit organization that envisions expanding networking to interplanetary space. Under his dedication and along with the entire membership, in June 2022, the IPNSIG successfully became a standing chapter of ISOC, known as the Interplanetary Chapter to promote its vision and to enhance the goals of the Internet Society.

Since he assumed the role of President in September 2020, he is leading efforts toward creating a common vision shaping the future of the interplanetary network and promoting activities including the establishment of six working groups and the publication of the “Strategy Toward a Solar System Internet for Humanity” in July 2021.

With his engineering background in avionics and communications, he has about 20 years of experience in the space field.  At the national space agency in Japan, JAXA, he has contributed to the development and operations of the International Space Station (ISS), including establishing a bi-directional communication link using Internet Protocol between the ISS and the Japanese ground system. He also led the Japanese flight control team as Flight Director between 2009 – 2010.

From April 2020 to March 2022, he had served at the Strategic Planning and Management Department of JAXA, where he had led the overall coordination of JAXA’s human spaceflight, space science and exploration programs.

Today, he serves at the Space Exploration Innovation Hub Center to promote research and development of innovative technology with non-space private sectors to enable future space explorations.

Scott C. Burleigh
(Vice President)

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 was the lead author for the specification for BP version 7 (RFC 9171). 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.

Mike Snell

Although he freely admits to being a Liberal Arts major gone bad, Mike Snell has spent over twenty years in various IT management and leadership positions at Cisco Systems and consulting/contracting firms. His technical interests include cybersecurity and technical business process change engineering.
Back in late 2011, Mike and his colleague, Konstantin Kalaitzidis, proposed to the board of the San Francisco Bay Area Chapter of the Internet Society that they launch a project to revitalize the inactive InterPlanetary Networking Special Interest Group (IPNSIG). Mike has served as Secretary/Treasurer and as Chair. Mike also served on the board of the San Francisco Bay Area Chapter of the Internet Society.
