IPNSIG now tax exempt

IPNSIG Receives Tax Exempt Status from the US Internal Revenue Service 

The Interplanetary Networking Special Interest Group (IPNSIG) has received confirmation from the US Internal Revenue Service that it is now qualified to operate as a non-profit, charitable, tax-exempt organization. In simple terms, this means that donations to IPNSIG can be treated by donors as tax-deductible contributions for US Federal Income Tax purposes. The IPNSIG Board believes that this status will provide additional incentive for supporters to provide resources that allow IPNSIG to accomplish its primary mission: to help standardize and demonstrate the readiness of the Bundle Protocol Suite to support the implementation of a Solar System Internet that can, in turn, support the exploration and eventual colonization of the Solar System.  

This was also the last major milestone to accomplish in order to formalize our status as an Internet Society Chapter (rather than a SIG). ISOC has changed the way they manage SIGs, and it made more sense for us to continue our affiliation with the Internet Society as a Chapter. However, we will be retaining the name IPNSIG in order to avoid confusion with many of our external friends, who have been used to referring to us as IPNSIG for over twenty years. We are incorporated in the State of California as IPNSIG, Inc. 

We want to thank especially our Secretary/Treasurer, Michael Snell, for his persistent due diligence in accomplishing this registration.

IPNSIG February Newsletter

Dear Membership,

On behalf of the IPNSIG board, I am pleased to announce the launch of the “IPNSIG Academy” – an educational platform that will cultivate interest, and passion which will result in building expertise in future generations as they work toward realizing an Interplanetary Network (IPN) in the coming 100 years.

Our vision at IPNSIG is focused upon enabling a common Solar System Internet (SSI) infrastructure that would benefit all humanity. Instilling this vision and conveying it to  future generations will push us forward in that bold endeavor.

The “IPNSIG Academy” will serve to propel those efforts by kicking off a series of talks, covering multiple facets surrounding the Interplanetary Network and SSI.

In 2022, the IPNSIG Academy will start by addressing the 100 year long-term vision of IPN/SSI; its technological developments (mainly in the area of the DTN protocols), its architectural concepts and issues around governance that would support the operation of the architecture and infrastructure. We have engaged many prestigious and prominent speakers from around the globe. They will be delivering talks relevant to each of these IPN areas. The last session will culminate in a workshop in which we will have discussions on Architecture and Governance with the entire membership.

(The detailed program will be posted on the IPNSIG website soon.)

IPNSIG continues to strive to do great things together with our membership and again, we are really excited to get engaged with you all at the Academy! We will update you with dates and times for each of the talks in further newsletters.
