What is on the Cygnus Cargo Module?

The Cygnus Cargo Module will be packed with more than 7,500 pounds of cargo and supplies for the astronauts on the International Space Station. Along with the cargo and supplies, the module will carry 38 cubesats or micro-satellites by NanoRacks of Texas, new habitat to grow plants on the ISS and the Spacecraft Fire Experiment-III (SAFFIRE-III).
Along with the SAFFIRE-III, the Cygnus will also carry the Reentry Data Collection (RED-Data-2) flight recorder to provide crucial data about the extreme conditions a spacecraft encounters during atmospheric reentry. The RED-Data-2 flight recorder was built by Terminal Velocity Aerospace.
Out of 38 cubesats, 28 will be used for the QB50 mission, which will study the lower thermosphere. Four of the cubesats will launch directly from the Cygnus during flight towards the ISS, while the remaining will be launched from the space station.

Sorry for writing again, according to Gunter´s website http://space.skyrocket.de/doc_chr/lau2017.htm
this Cygnus is called "SS John Glenn".

Well, I heard half right about the four cubesats! :-)

I have to wonder if they picked this particular Cygnus for the honor because it is flying on an Atlas, just like Glenn's first ride into space.

OA's statement on the launch date:

Mission Update - March 15, 2017

NASA, Orbital ATK and United Launch Alliance (ULA) are now targeting the launch of Orbital ATK’s seventh commercial resupply services mission to the International Space Station at 9:00 p.m. EDT Friday, March 24. An option exists to move the launch earlier to March 23, if the Eastern Range becomes available. The additional time allows the ULA team to replace and retest a first stage hydraulic component. Orbital ATK has contracted with ULA for its Atlas V rocket for the launch service, which will lift off from Cape Canaveral Air Force Station in Florida. Orbital ATK’s Cygnus cargo spacecraft is packed with 7,600 pounds of supplies and research for crew aboard the orbiting laboratory.

Does anyone know when the "if the Eastern Range becomes available on the 23rd" option will be known for certain?  I.e. At what point can we safely assume the 23rd is out and the 24th is when they'll proceed toward?

Chris has said that it should be known by the end of the day tomorrow. It looks like SpaceX has the range on the 23rd for a static fire for the SES-10 launch. LC-39A might not be ready in time in which case the static fire would be pushed to after this launch and ULA would get the range.

Launch fans: Mark your calendars: #AtlasV #OA7 is now scheduled for Tuesday, Apr 18.
Space is not Highlander.  There can, and will, be more than one.

NASA, Orbital ATK and United Launch Alliance (ULA) are now targeting April 18 for the launch of Orbital ATK’s seventh contracted commercial resupply services mission to the International Space Station. ULA has developed a plan to resolve an earlier booster hydraulic issue, and is moving forward with launch vehicle processing. Both the Atlas V rocket and Cygnus spacecraft remain secure. Several tons of cargo including crew supplies and science experiments packed aboard Cygnus remain in good shape.

Orbital ATK is proud and honored to name the OA-7 Cygnus cargo delivery spacecraft after former astronaut and U.S. Senator John Glenn

We somehow ended up with two threads for this mission.  Let's use the thread in the ULA section to cover the launch, and the thread in the O/ATK section for payload/on-orbit discussion.

There are 38 cubesats being launched aboard this Cygnus, 34 that will be transferred over to the space station for eventual deployments from the Japanese Kibo module’s airlock and four that are mounted externally to the cargo ship. After Cygnus departs the station in July, it will climb to a higher altitude, around 310 miles, and eject them into space.
The six other cubesats going to the station include four from NASA, one from the Defense Department and one commercial. They include a mission to measure the cosmic X-ray background, one to test a new light-weight, longer-life battery system designed for the cold temperatures of space and another to measure ice particles within clouds.
The four riding in the Cygnus external deployer are LEMUR-2 cubesats for meteorology and ship tracking.
So it will be four Lemur 2.
One NASA cubesat is missing, the DOD cubesat could be Biarre-Point.

Its spelt Biarri-Point. Biarri is an Aboriginal word that means to hunt or to track. It was mentioned at the South Australian Space Forum last year that Biarri would be flying to the ISS on a resupply mission early this year.

Still no info on the fourth NASA CubeSat?

(The other three NASA Cubesats are CXBN-2, CSUNSAT-1 and IceCube)

Thanks Gunter. Looks like the person I heard about Biarri-Point was wrong. It was mentioned at last years South Australian Space Forum that Biarri-Point would be flying early this year on a mission to ISS. Perhaps it will fly on SpX-11.

Hmm, it gets a little but confusing.
Nanoracks Cubesat list contains the 38 cubesats posted above.
But the Australian government also acknowledges the launch of Biarri-Point https://www.dst.defence.gov.au/news/2017/04/20/biarri-satellite-heads-space

So there are now 39 (or more) Cubesats?

Addendum: I should read more carefully. The Nanoracks list of 38 cubesats says: "Our satellites on board include:" - which hints to more than 38 cubesats.
