Cygnus will remain berthed for approximately one month to allow the astronauts on Space Station to perform the transfer of the lab to Cygnus and then back to the station where it will remain.

What exactly is the point of this demonstration?  Cygnus remains berthed during the test, correct?  So, it's not demonstrating Cygnus as a free flying lab.  They move the lab module to Cygnus, then move it back all the while the vehicle stays berthed to the station ....  Is the ISS so hard up for lab space that they would "off load" an experiment for a month to run in Cygnus?  Seems strange.
Shouldn't reality posts be in "Advanced concepts"?  --Nomadd

Need to test the Cygnus systems. One step at a time.

And what's the next step? Using Cygnus as a free-floating lab? Increasing the ISS' total lab space by having a Cygnus regularly attached and being replaced a la Progress when its 90 day orbital lifetime expires? Both? Or something else?

Some or all of those. Tests including lower atmosphere, temperature extremes, or other experiments that aren't safe in the crewed portion. A reusable SAFFIRE setup perhaps?

Part of the difficulty in utilizing the ISS is the limits on the kinds/risks of experiments it can support.

Proving that the experiment's environment is the same on ISS as on Cygnus normalizes the extension of the Cygnus environment as same.

In the microgravity case, eventually Cygnus might be able to "better" the environment beyond ISS quality/safety/isolation. While still allowing access to prime/remedy/extract results from experiments.

It's not the need for more space, its about increasing utility.

Plus, if Cygnus can operate for longer periods of time autonomously, it can have other uses.

Cross-post from the "Schedule of ISS flight events (part 2)" thread:
Will there be experimentation aboard in free-flying mode, rather than aboard Cygnus berthed?

mid-December - Cygnus (OA-8) with TangoLab unberthing (from Unity nadir) and releasing by SSRMS

2018
early - Cygnus (OA-8) with TangoLab capture and berthing (to Unity nadir) by SSRMS

These two items seem to suggest that Cygnus (OA-8) will be performing a freeflying experiment with TangoLab aboard (given the release in mid-Dec. and recapture and berthing in early 2018).  Where is that info coming from?  In the mission factsheet posted just above, it only mentions moving TangoLab into the Cygnus and then offloading it back into ISS while Cygnus remains berthed to the station.  No info on releasing and recapture of Cygnus, etc.

EDIT 11/6: No.  Cygnus release, no return to ISS, on December 4.

NASA TV Coverage Set for Next Resupply Mission to International Space Station

NASA commercial cargo provider Orbital ATK is scheduled to launch its eighth mission to the International Space Station at 7:37 a.m. EST Saturday, Nov. 11 NASA’s Wallops Flight Facility in Virginia. Live launch coverage will begin at 7 a.m. on NASA Television and the agency’s website.

NASA TV also will air two prelaunch briefings Friday, Nov. 10. At 11 a.m. mission managers will provide an overview and status of launch operations, and at 3 p.m. scientists and researchers will discuss some of the investigations and technology demonstrations to be delivered to the station.

The Cygnus cargo spacecraft will launch on Orbital ATK’s upgraded Antares rocket from Pad 0A of Virginia Space’s Mid-Atlantic Regional Spaceport, located at Wallops. Following launch on Nov. 11, NASA TV coverage of the spacecraft’s solar array deployment will begin at 9 a.m. and a post-launch news briefing will held at approximately 10 a.m.

Under NASA’s Commercial Resupply Services contract, Cygnus will carry about 7,400 pounds of crew supplies and hardware to the space station, including science and research in support of dozens of research investigations that will occur during Expeditions 53 and 54.

Cygnus will carry several CubeSats that will conduct a variety of missions, from technology demonstrations of laser communication and increased data downlink rates to an investigation to study spaceflight effects on bacterial antibiotic resistance. Other experiments will advance biological monitoring aboard the station and look at various elements of plant growth in microgravity that may help inform plant cultivation strategies for future long-term space missions. The spacecraft will also transport a virtual reality camera to record a National Geographic educational special on Earth as a natural life-support system. 

Cygnus will arrive at the station on Monday, Nov. 13. Expedition 53 Flight Engineers Paolo Nespoli of ESA (European Space Agency) and Randy Bresnik of NASA will use the space station’s robotic arm to capture Cygnus at about 5:40 a.m. NASA TV coverage of rendezvous and capture will begin at 4:15 a.m.

After Canadarm2 captures Cygnus, ground commands will be sent to guide the station’s robotic arm as it rotates and attaches the spacecraft to the bottom of the station’s Unity module. Coverage of installation will begin at 7 a.m.

Cygnus will remain at the space station until Dec. 4, when the spacecraft will depart the station and deploy several CubeSate before its fiery reentry into Earth’s atmosphere as it disposes of several tons of trash.

This Cygnus spacecraft is named in honor  of the former astronaut Eugene “Gene” Cernan, the last human to step foot on the Moon during the Apollo 17 mission. Cernan set records for both lunar surface extravehicular activities and longest time in lunar orbit. He died in January 2017.

As it will come up, the temp at Wallops on Friday night/Saturday morning will be below freezing at launch time.  This is, at present, not a constraint for Antares.  The official forecast low at the pad that night is - currently - 29F before an 07:37 EST launch - at which time the temp is still predicted to be below freezing.

I asked Trina at Orbital ATK for the launch weather commit criteria.  This is the response from Kurt Eberly, VP/Antares Program Manager.

"Our ambient temperature constraint is 20F. Our capability is driven by the fact that we blow a lot of highly conditioned air into  3 areas of the vehicle that contain the Cygnus spacecraft, avionics, batteries, ordnance, and the second stage solid rocket motor, which are the temperature sensitive items on the rocket. The LOX we load into the vehicle is at roughly -295F, so a cold ambient air temperature is of no concern for most of Stage 1, in fact it just makes it easier to keep the LOX cold on its trip from the storage tank to the rocket.
 
The forecast low for Friday night is 29F, so we should be OK to launch."

Cygnus Cargo Mission Due for Launch on Veteran’s Day
 

Orbital ATK’s eighth commercial cargo mission is set to launch to the International Space Station at 7:36 a.m. EST Veteran’s Day on Nov. 11. The Antares rocket carrying the Cygnus cargo craft will blast off from Wallops Flight Facility, Virginia, with over 7,000 pounds of food, supplies and research gear.

Two astronauts will be inside the cupola commanding the Canadarm2 robotic arm to capture Cygnus when it arrives Monday at 5:40 a.m. Flight Engineer Paolo Nespoli will capture Cygnus, dubbed the “SS Gene Cernan”, assisted by Commander Randy Bresnik. Cygnus will deliver numerous advanced science experiments exploring a wide variety of subjects including communication and navigation, microbiology, animal biology and plant biology.

Meanwhile, the orbiting Expedition 53 crew members continued investigating biology and robotics in microgravity.

NASA astronaut Mark Vande Hei collected and stowed saliva samples today that will be analyzed later for a study on the human immune system and metabolism. Bresnik took panoramic photographs inside the Kibo laboratory module to prepare for the upcoming Astrobee experiment. Astrobee consists of three free-flying, cube-shaped robots that will be tested for their ability to assist astronauts and ground controllers.

Given Orbital ATK's direct and detailed answer to the sub-freezing temps expected at the pad Friday night, this is not a concern for Saturday morning.

Also, there are numerous ways to prevent those sorts of issues that launch facilities located in places where it freezes understand and use (i.e. heaters).

Incidentally if they launch Saturday morning and it is in the upper 20's this will make it the coldest launch of an Antares so far. Right now it's ORB-1 in January 2014 with a launch temp of about 35F (1.5C)
