Chapter members might find this IEEE Explore article interesting. It explains how planetary space exploration increasingly will rely upon robots (like the Mars rovers) for exploration. In particular, NASA and other space agencies are looking to place humans in orbit around Mars and use them to control more detailed exploration by remotely controlling robots on the surface. DTN will play a critical role in providing reliable data communication within the constrained network environments of outer space and the planetary surface itself.

METERON is a joint project, led by the European Space Agency (ESA), with support by NASA, that is evaluating and demonstrating DTN and other technologies for use in future human exploration of space.

DTN Making Progress in Networking Standards

DTN making progress as both a terrestrial Internet standard and as a standardfor space communications

The global standards-setting organization for the Internet—the  IETF—has launched  DTN Working Group to formally develop and adopt DTN as standard for Internet data communications. The DTN WG  is working on a major revision to the core Bundle Protocol specification (currently RFC 5050). An html version of their progress on the draft is available at:

 You can sign up for regular updates about the activities of the IETF DTN Working group at:

 CCSDS is a global standards-setting organization for space data systems used in civilian space flight. The have completed their final review and have published a recommended standard for the Bundle Protocol for use in global space data communication:

Newly Revised DTN Tutorial v3.2 Available

Warthman Associates

Warthman Associates






Forrest Warthman, of Warthman Associates, with assistance from Scott Burleigh of NASA/JPL, has recently completed revisions and updates to the “DTN Tutorial” document to bring it up to date with developments in DTN since the last update was published three years ago. He has also created a version of the document intended for less-technical folk (the “DTN Primer v3.2″).

Many thanks to Forrest for donating his time and skill to this effort!

We have a great line-up of renowned speakers for our event in Washington, DC, on May 18th! See our previous post for more details and a link to the registration site.

Scott Burleigh


Mr. Burleigh co-authored the specification for the CCSDS (Consultative Committee for Space Data Systems) File Delivery Protocol (CFDP), an international standard for file transfer over interplanetary distances.  Mr. Burleigh developed the first implementation of CFDP, which was adapted for operational use on a number of flight missions, including JPL’s Deep Impact comet exploration mission.

Mr. Burleigh was a co-author of the DTN Architecture definition (Internet RFC 4838) and also of the specification for the DTN Bundle Protocol (BP, Internet RFC 5050).  In addition, he is a co-author of the specifications for the Licklider Transmission Protocol (LTP, Internet RFCs 5325 through 5327) supporting data block transmission reliability at the data link layer.

Mr. Burleigh leads the development and maintenance of the “Interplanetary Overlay Network” (ION) implementations of BP and LTP software, with the long-term goal of enabling deployment of a delay-tolerant Solar System Internet.  The ION software has been flight tested on-board the EO-1 Earth-orbiting spacecraft and on the EPOXI spacecraft in deep space, and it will begin providing Delay-Tolerant Networking service to science investigation payloads on the International Space Station later this year. Mr. Burleigh chairs the ION Working Group.
