2015 Events

 

2014-11-19_15-33-49 IPN LogoIPNSIG is now the InterPlanetary Networking Chapter of the Internet Society. We will be staging our second IPN speakers event next March 6th, 2015, at the Boeing facility on Long Bridge in Arlington, VA (just down the road from the Pentagon). Our theme this year is: Space Technology Innovations—Paving the Way for Exploring our Solar System. More details will be posted here, along with links to the EventBrite registration site, the speakers bio page, and information about how to view the live webcast and watch presentation videos on demand. Directly after the speaker presentations, we will be holding our annual member meeting (which will also be webcast live). Join us!

 

 

 

 

CCSDS Update

 

 

 

CCSDS-Logo-border

Board member Keith Scott provides this update on DTN activities within CCSDS.

CCSDS is in the process of review and approval of two key DTN protocols of particular interest to the InterPlanetary Networking community: the Licklider Transport Protocol and the Bundle Protocol. CCSDS approval will establish LTP and BP as Space Data Systems standards for all member space agencies.

LTP review is pretty much all but done. BP is in its third member agency review, and is scheduled to complete that review in October, 2014.

In other news, deployment of DTN for operational communications between earth and the International Space Station is expected to occur this Fall. The NASA Change Request for deploying DTN for ISS operations was approved in 2013. DTN is already used for most communications between ISS experimental payloads and earth-based researchers and operators.

 

 

STINT workshop at IEEE SMC IT 2014

The fifth annual IEEE Space Mission Challenges for IT (SMC IT) Conference is coming up September 24th – 26th, 2014, at Laurel, Maryland. There will be a Space Terrestrial Internetworking (STINT) workshop co-located with the SMC IT conference. The theme for the workshop will be “Operationalizing the Network Environment”. Presentations will cover the following topics:

  • Delay and Disruption Tolerant Networking
  • Modeling the Dynamics of Mobile Space-Based Networks
  • Autonomous Configuration and Control of Network Nodes
  • Protocols, Applications, and Concepts for Network Management
  • End-to-end Security Services Across an Internetworking Overlay.
  • Commercial, Scientific, and/or Government Missions Enabled by Space-Terrestrial Internetworks

For more information, please visit the STINT workshop web page: http://www.stintworkshop.org/

Many thanks to Juan Fraire for the excellent workshop poster.

DTN BoF at IETF 90

There is an approved DTN Birds of a Feather (BoF) group meeting at IETF 90. It’s currently scheduled for 1520 – 1650 on Wednesday, July 23rd. For more information about the BoF group, including charter, problem and solution statements, go to:  http://trac.tools.ietf.org/bof/trac/wiki/WikiStart

For the most current IETF agenda, including the room for the BoF, go to: http://trac.tools.ietf.org/agenda/90/

For the BoF meeting agenda, go to: http://trac.tools.ietf.org/agenda/90/agenda-90-dtnwg.html

This is an important first step on the road to standard adoption for DTN. If you are attending IETF, we strongly encourage you to attend the DTN BoF.

DTN BoF for IETF90

Exciting news!

Fred Templin (Boeing) has been leading the charge to initiate a Birds of a Feather (BOF) group at this July’s IETF meeting in Toronto, Canada. A mailing list has been created to discuss the organization of the group. You can get more information and sign up for the list at:

https://www.ietf.org/mailman/listinfo/dtn

An introductory message including the draft working group charter and proposed BoF agenda will be published soon.

SPHERES enhancements on ISS

Here’s an interesting article on the  Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES—and isn’t THAT a reach for a catchy acronym?) on board the International Space Station (ISS) from NASA Ames Research Center:   http://www.nasa.gov/mission_pages/station/research/news/smart_spheres/#.UyxiVPldWa9

The photos below show SPHERES—small, self-propelled robotic sphere (rather: sphere-like) units about the size of a volleyball that are being tested on board ISS for various maintenance and emergency repair tasks. SPHERES have used Android smart phones for communication and control since 2011. Now a new version is being flight tested before being launched later this year to provide enhanced capabilities (such as a 3-D positional sensor). The phone being tested is the Google Project Tango Android smart phone.

NASA planning long-term Laser Communications Mission (LCRD)

NASA recently announced a significant review milestone for the Laser Communications Relay Demonstration (LCRD) scheduled for 2017.

The LCRD project is NASA’s first long duration optical communications mission. This demonstration builds upon NASA’s highly successful Lunar Laser Communications Demonstration (LLCD) mission (which validated the use of DTN for laser communications to the moon and back). LCRD will conduct a two-year demonstration of optical relay services to determine how well the system operates and collect long-term performance data. Full details are available here:

DTN Use in Slovenian Karst Cave

An article published in  the scientific journal Natural Hazards and Earth System Sciences recognizes work of the N4C Community using (DTN) technology for automatic data transfer  in a huge karst cave system in Slovenia. The cave allows tourists, who ride a train deep into the cave, potentially exposing them to air quality health risks. DTN technology allowed the establishment of an early warning system (EWS) for poor air quality.  The experiment placed a DTN “data mule” (a DTN-enabled computer with WiFi connection) on the train. The data mule on the train received data from a meteorological station deep within the cave.  It transported the data to the train station at the cave entrance, which then updated the surveillance system, providing alert capabilities of deteriorating air quality conditions deep within the cave.  The full text of the paper is available here:
