Will the jacket it's wrapped in be like the banana peel and will fall away during launch, or will it be removed prior?

OA have done both. Majority go with a T+0.1 approach.

ORBITAL ATK SET TO LAUNCH MINOTAUR IV ROCKET CARRYING ORS-5 SATELLITE FOR THE US AIR FORCE

 

ORS-5 Launch will be 26th Flight for Minotaur Family of Launch Vehicles

 

   
 

 

Dulles, Virginia 24 August 2017 – Orbital ATK (NYSE: OA), a global leader in aerospace and defense technologies, today announced it is in final preparations to launch the company’s Minotaur IV rocket from Cape Canaveral Air Force Station, Florida, on Friday, August 25, at approximately 11:15 p.m. EDT. The Minotaur IV will carry the U.S. Air Force’s Operationally Responsive Space-5 (ORS-5) spacecraft, which will monitor satellites and space debris to aid the U.S. military’s space situational awareness.

 

Building on the Minotaur family’s 100 percent success rate, this mission will mark the 26th flight for Orbital ATK’s Minotaur product line and the sixth flight of the Minotaur IV configuration. Minotaur vehicles are based on government-furnished Peacekeeper and Minuteman rocket motors that Orbital ATK has upgraded and integrated with modern avionics and other subsystems to produce an affordable launcher based on reliable, flight-proven hardware. The Minotaur IV is capable of launching payloads up to 4,000 lbs. (or 1,800 kg.) to low-Earth orbit. Minotaur rockets have previously launched from ranges in California, Virginia and Alaska. This will be the company’s first launch of a Minotaur rocket from Launch Complex-46, managed by Space Florida.

 

“Launching from Cape Canaveral Air Force Station expands the Minotaur launch vehicle’s capability to meet specific mission requirements for our customer,” said Rich Straka, Vice President and General Manager of Orbital ATK’s Launch Vehicles Division. “We are pleased to be able to provide continued launch support for the ORS office with our reliable Minotaur family of launch vehicles and look forward to a successful launch of the ORS-5 mission.”

 

The Minotaur product line is provided via the Orbital/Suborbital Program (OSP-3) contract and managed by the U.S. Air Force Space and Missile Systems Center (SMC), Launch Enterprise, Experimental Launch and Test Division (LE/LEX), and Rocket Systems Launch Program (RSLP) located at Kirtland Air Force Base, New Mexico.

 

Live coverage of the Minotaur launch and details about the mission are available at www.orbitalatk.com.

All I can find is 2 apparently classified payloads from an unidentified USG agency and an unnamed DARPA payload.

SN identifies them all in its article on the launch.

Quote
The secondary payloads include two 1.5-unit CubeSats, weighing around 3.3 pounds (1.5 kilograms) each, from Los Alamos National Laboratory. A larger shoebox-sized CubeSat from the Defense Advanced Research Projects Agency, or DARPA, with a weight around 6.6 pounds (3 kilograms) is also hitching a ride.

It also provides more information on the mission of the primary payload.

Quote
Air Force Col. Shahnaz Punjani, director of the ORS office, compared the ORS-5 satellite’s function to the A-10 attack jet, an aircraft that carries a powerful armor-piercing cannon.

“When people talk about the A-10 aircraft, (they say) it’s really a gun with an airplane wrapped around it,” Punjani said. “In this case, the ORS-5 satellite is essentially a telescope in low Earth orbit with a spacecraft wrapped around it, looking at the geosynchronous belt.”

Another way to look at it is to compare the ORS-5 satellite to an airport radar, said Grant Stokes, head of the space systems and technology division of the Massachusetts Institute of Technology’s Lincoln Laboratory, where the spacecraft was developed and manufactured.

“It’s sort of analogous to a surveillance radar at an airport, which goes around and around, surveilling the domain,” Stokes told reporters in a prelaunch briefing Thursday. “Once per orbit, what ORS-5 will do is scan the GEO (geosynchronous) belt and keep track, essentially, of all the items there.

“The GEO belt is particularly important,” Stokes said. “There’s a huge collection of satellites there, and a tremendous amount of economic value in that special orbit, so it is one that generally we want to keep fairly good tabs on what’s there and where things are.”

Quote
Designed for a three-year mission, ORS-5 should feed military officials data on how objects are moving around geosynchronous orbit. After identifying which objects might be threats, the Air Force could task the more capable SBSS Block 10 satellite to take better pictures, or send one of the military’s four close-up inspection satellites in geosynchronous orbit to take a closer look, according to Lt. Col. Heather Bogstie, ORS-5 program manager.

The data output from ORS-5 “gives you dots on a screen,” Stokes said.

“We very carefully measure how bright they are, but it does not resolve in any way,” he said. “It’s a dot at a distance of something like 40,000 kilometers (nearly 25,000 miles).”

SMC ORS-5 Launch Broadcast Video


Space and Missile Systems Center Los Angeles AFB
Published on Aug 25, 2017


The Operational Readiness Space Office, located at Kirtland AFB, plans and prepares for the rapid development of highly responsive space capabilities that enable delivery of timely warfighting effects and, when directed, develop and support deployment and operations of these capabilities to enhance and assure support to Joint Force Commanders' and other users' needs for on-demand space support, augmentation and reconstitution. ORS' latest satellite ORS-5 is launching from Cape Canaveral, Florida. The satellite will provide delivery space situational awareness capabilities at a significantly reduced cost compared to larger, more complex satellites, and serves as a gap filler mission for the Space-Based Space Surveillance (SBSS) Block 10 mission, originally launched in 2010.

Light rain and heavy clouds here at KSC ~5pm. Hopefully will clear up by launch time.  I'm going to head over to fishlips for dinner with my boy, maybe get a glimpse of OCISLY.

I believe the other two satellites were identified earlier in this thread:
