Moving forward to an Internet that's Interplanetary in scope and function…
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

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.
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:
An introductory message including the draft working group charter and proposed BoF agenda will be published soon.
47 papers on have been submitted for review for this upcoming issue of the scholarly journal, Elsevier Ad Hoc Networks. The issue should be coming out in Fall, 2014.

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 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:
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:

On February 4th, 2014, Space.com reported that astronauts aboard the ISS will start launching 33 cubesats from the ISS on Thursday (Feb 6th, 2014) now that a launcher has been installed. Michael Johnson, NanoRacks chief technology officer, said this may be a “world-record deployment.” Most of these satellites belong to Planet Labs as part of its Flock 1 constellation of Earth-observing spacecraft. According to the article, Johnson stressed that the launches pose no “collision risk” to the station because of how the satellites will be deployed.

On Feb 5, 2014 Meghan Neal at Motherboard writes on the Outernet project, which aims to beam “‘high-quality’ news and educational content” free of charge to everyone on Earth through a constellation of nanosatellites. Neal notes there is a large amount of skepticism over how the project would be funded, how the content would be selected, and whether other agencies would allow this “rogue alt-internet” to go forward. Neal comments that despite these doubts, the “pie-in-the-sky technoutopian vision” has a “very optimistic timeframe” that includes testing aboard the ISS this September. Neal adds that the team has already requested time at the ISS but did not mention the status of the request.
