NROL-129

Two Minotaur launches planned this year from Virginia (https://spaceflightnow.com/2019/03/21/two-minotaur-launches-planned-this-year-from-virginia/), dated March 21, 2019
Quote
In response to questions from Spaceflight Now, the Air Force confirmed plans for another Minotaur launch for the NRO — a mission designated NROL-129 — in the fall of this year.

The NROL-129 mission will launch aboard a Minotaur 4 rocket...
<snip>
In a written statement, Galbreath said the Air Force awarded the NROL-129 launch contract in December 2017 to Northrop Grumman Innovation Systems, then known as Orbital ATK. The NROL-129 launch order is valued at $38 million...<snip>

Launch services...were arranged through the Air Force’s Orbital/Suborbital Program-3 contract.

First Minotaur launches at Wallops since 2013, which also had two late year launches.

If all five launches (Antares x2, Minotaur x2, Electron x1) take place this year, it will also be the most orbital launches from Wallops in a single year. 1964 saw Wallops launch 6 Scout rockets, but 3 of those were suborbital.

Minotaur IV is sometimes used as a suborbital rocket, but all instances of that in the past have been from Vandenberg.

Please explain in the area below why an STA is necessary:
This FCC STA is required in support of the L-129 Mission. The Mission Requirements Document (MRD) requires this effort in support of the "A.8" over the horizon telemetry enhancement to the Minotaur IV Launch Vehicle. This enhancement requires the utilization of the Tracking and Data Relay Satellite System (TDRSS), TDRS-6 in order to satisfy the mission requirements. TDRS-3 and TDRS-12 may also be used as required.

From the July 2 update of the SFN Launch Schedule (https://spaceflightnow.com/launch-schedule/):
Launch is scheduled for the fourth quarter of 2019.

Perhaps this launch is taking a hypothetical launch slot from NROL-111?  That launch has been delayed from the end of 2019 to TBD.

Cross-post; NRO tweet probably refers to this mission, instead of NROL-111.
NRO tweet probably about this mission, stating "late 2019". https://twitter.com/NatReconOfc/status/1149417529217081344

Wallops hasn't hosted an NRO launch before. They've done accreditation for USAF launch though. I would probably expect they'll do it, but expect much less access than is given for Antares launches

A National Reconnaissance mission, NROL-129, is scheduled to fly sometime in the spring on a Northrop Grumman Minotaur 4 launch vehicle from Wallops Island, Virginia.

An Air Force Research Lab experimental payload will fly in the spring aboard a Rocket Lab Electron vehicle from the company’s new launch pad at Wallops Island. The STP-27RM Space Test Program mission is an experimental satellite called Monolith that will be used for space weather research.
...
Another NRO mission, NROL-111, will launch in late 2020 from Wallops Island aboard a Northrop Grumman Minotaur 1 vehicle.

Minotaur IV is sometimes used as a suborbital rocket, but all instances of that in the past have been from Vandenberg.
That would be Minotaur-III (TLV) and Minotaur-IV-Lite (R&D, Sounding Rocket). The Minotaur-IV Lite version uses the base Minotaur-III vehicle minus the Stage-4 GFE PBM or Super HAPS but at least for the flights flown uses the Minotaur-IV motor burn profile as if it had 4+ stages.

SLC-8 is being renovated for the next Minotaur-IV-Lite launch series for the CSM programme.

Any visible launch campaign activity yet?

Will the Minotaur be horizontally integrated inside a processing facility (out of sight)?

EDIT: Per RH117's response, Minotaur stacking should be visible. (https://forum.nasaspaceflight.com/index.php?topic=47724.msg2101674#msg2101674)

So, any activity sightings by Delmarva denizens?

Will the Minotaur be horizontally integrated inside a processing facility?
Minotaur stages are shipped horizontally and stacked vertically on the launch mount. The sole exception are the common stages used by Minotaur-C and Pegasus, which are integrated horizontally as a combined stack on a processing stand then rolled as one unit onto its transport trailer and for Minotaur-C is lifted as one and placed on either the 92 inch Peacekeeper GFE or GFE derived Castor-120/120XL stage 0 booster. All Minotaur GFE stages and hardware use GFE transporters which raise the stages vertically but instead of lowering them into a silo, bunker or mobile TEL launch tube are craned from the transporters onto the missions launch mount. Commercial stage equivalents use non GFE transportation. Upon using up all GFE those Minotaur versions will switch to NG's commercial equivalents which are being co-developed with the Large Class Stage project (LCS-I, II, III motors and PBS developed for the all 92 inch GBSD version before granting ARH, Inc a concession to avoid political and legal actions on the GBSD award) with Castor-120XL and Castor-30XL being two of them.

Re: previous question about coverage:

NASA’s Wallops Flight Facility plans to provide a live video webcast of the Minotaur 4’s liftoff July 15, but officials are not opening the NASA Visitor Center at Wallops for launch viewing or hosting media representatives to cover the launch in person. NASA cited the coronavirus pandemic as the reason for the closure.

The #NROL129 mission is represented by two launch patches featuring two warrior figures working together to defend our nation’s interests and deny our enemies sanctuary. The patches include the phrase “Our Time has Come,” which symbolizes that these payloads will enable the NRO’s continued support to both defense and intelligence operations in support of national security.

Launch is scheduled for no earlier thank 15 July from NASA Wallops Flight Facility, Virginia.

A question about public viewing:

Pad 0B is very close to the Antares Pad 0A, but slightly south of it.  Also, we're dealing with a different rocket, using different types and amounts of fuel.

So do we think that the same exclusion zone applies for public viewing as with Antares?  In particular, I am wondering if Arbuckle Neck Road will be closed but the Old Ferry Dock open.  Thoughts?

Public viewing sites will be monitored for crowd size. County and state officials have the right to discourage gatherings for viewing but I have not yet found anything prohibiting those sites.

I'm going to guess that the Orion 38 fourth stage motor does not burn until T+45 minutes to T+1 hour or so. 

Nice to see a real rocket launch.  Woof, and outta here!

That seems unlikely unless the third stage achieves orbit, which it doesn't normally.
On the 2010 SBSS launch, previous use of this particular config of Minotaur, the stage 4 burn was at T+12 min 41s.

That's my assumption.  Also note the nominal WFF orbit inclination listed at 43 degrees in the Guide, though we have nothing official about this launch.  The Orion 38 fourth stage motor is mounted in a Guidance and Control Assembly, which also supports avionics and a cold gas thruster system for 3-axis control during coast, burn, and spacecraft separation, etc.  The GCA/Orion 38 unit may do a bit of orbit lowering after spacecraft separation, but probably can't directly deorbit, but I'm guessing.

Northrop Grumman Successfully Launches Minotaur IV Rocket Carrying Satellite for the National Reconnaissance Office

Minotaur product line boosts flawless record to 27 missions

WALLOPS, Va. – July 15, 2020 – Northrop Grumman Corporation (NYSE: NOC) successfully launched its Minotaur IV space launch vehicle and placed a National Reconnaissance Office (NRO) spacecraft into orbit at 9:46 a.m. EDT on July 15. The Minotaur IV was launched from the Mid-Atlantic Regional Spaceport Pad 0B at NASA’s Wallops Flight Facility.

“This mission marks the 27th consecutive successful launch for the company’s Minotaur product line which celebrates its 20th anniversary this year,” said Kurt Eberly, director, launch vehicles, Northrop Grumman. “Minotaur’s record of success along with its ability to responsively launch from multiple spaceports continues to be a valuable asset for our customers.”

The NROL-129 launch (L-129) was the seventh Minotaur IV flight. The Minotaur IV is capable of launching payloads of up to 4,000 pounds (or 1,800 kilograms) to low earth orbit. This mission’s Minotaur IV configuration included three decommissioned Peacekeeper stages and a Northrop Grumman manufactured Orion 38 solid fuel upper stage. The Minotaur rockets are manufactured at Northrop Grumman’s facilities in Chandler, Arizona; Vandenberg, California; and Clearfield and Magna, Utah.

The Minotaur family of launch vehicles is based on government-furnished Peacekeeper and Minuteman rocket motors that Northrop Grumman has integrated with modern avionics and other subsystems to produce a cost-effective, responsive launcher based on flight-proven hardware. Minotaur rockets have launched from ranges in Alaska, California, Florida and Virginia.

The vehicle used to launch the L-129 mission was procured under the OSP-3 contract administered by the U.S. Space Force Space and Missile Systems Center’s Launch Enterprise Small Launch and Targets Division at Kirtland Air Force Base in New Mexico. Minotaur vehicles are currently available to customers under the OSP-4 contract.

Northrop Grumman solves the toughest problems in space, aeronautics, defense and cyberspace to meet the ever evolving needs of our customers worldwide. Our 90,000 employees define possible every day using science, technology and engineering to create and deliver advanced systems, products and services.

Was a little surprised at the astonishment of the guys doing the commentary at the Minotaur's speed.  It's basically a Peacekeeper ICBM (for all intents and purposes).  It was designed to get out of Dodge ASAP, both because nukes could be going off any second and to give an enemy as short of time as possible to view it under boost.  IIRC the ICBMs 3 stages were designed to be burned out in 2-1/2 minutes.  That's why there is no pause between staging (the ICBM wouldn't have paused between the 2nd and 3rd stage).

The NSF webcast commentary guys are not familiar with the flight characteristics of solid fueled strategic ballistic missiles and why those characteristics are needed. They are civilians.  ;)

I mean, I've watched several videos of ballistic missile flights with the instant roll. I hadn't realized the full extent of the INSTANT ACCELERATI :o N of the missile. Seeing the rocket just take off like that was shocking.

I think a part of me was thinking "surely that roll is a one off mistake" when watching the tests. Nope, it's to be expected every single time.  :o :o :o

2.45 T/W ratio at launch, or thereabouts.  Hello, and goodbye!  Mach 1 through 4 callouts were at about T+17.5, 30, 42, and 50 seconds, respectively.  Remember also that PK originally was a cold launch missile that popped out of its silo to ignite while hanging mid-air.

A NRO Video shown at the 2021 Space Symposium likely shows the four satellites being integrated on the launch vehicle at the T 0:11 mark.

There are also other small satellites shown (T 0:34, 0:38), but these appear to be different from the NROL-129 quadruplet.
