Note the cropped image--probably to obscure the service module.

There is mention up-thread regarding a polar or Sun-synchronous orbit for either NROL-69 or USSF-36NROL-69 went to a NOSS/Intruder orbit; could this be a polar launch for the X-37B?

I think the polar mention was because the Vandenberg mention in the award. I don't see any mention of Polar or SSO in the award documents. My guess is that the Vandenberg comment is related to fleet surveillance for launches from there.

We’re also demoing the world’s highest performing quantum inertial sensor ever used in space. Bottom line: testing this tech will be helpful for navigation in contested environments where GPS may be degraded or denied. (3/4)
Mhh, "testing quantum navigation", "reduce reliance on GPS". I wonder they have also have a version of an X-ray XNAV Pulsar navigation and SEXTANT on board to compare? It was tested on the ISS so this looks like a mission where you can compare all sensors in the same context. Maybe a nice question for a press conference ;) ?

This will likely be B1095-2, not B1096. B1095 has been vacant since May meaning it's likely reserved for this while CRS missions don't usually have such a long reserve.

US Space Force prepares X-37B Mission 8 for launch

The U.S. Space Force, in partnership with the Air Force Rapid Capabilities Office and SpaceX, is making final preparations to launch the eighth mission of the X-37B Orbital Test Vehicle (OTV-8) on Aug. 21 from Kennedy Space Center, Fla.

The eighth mission of the X-37B Orbital Test Vehicle will launch on a SpaceX Falcon 9 rocket, designated USSF-36, with a wide range of test and experimentation objectives. These will include demonstrations of high-bandwidth inter-satellite laser communications technologies and enhanced space navigation using the highest performing quantum inertial sensor in space.

"OTV-8 exemplifies the X-37B's status as the U.S. Space Force's premier test platform for the critical space technologies of tomorrow. Through its mission-focused innovation, the X-37B continues to redefine the art of the possible in the final frontier of space," said AFRCO Acting Director William Blauser.

The X-37B program, which first launched in April 2010, has accrued 4,208 days in operation. Previous X-37B missions have successfully demonstrated the X-37B spacecraft’s ability to alter its orbital trajectory using a novel aerobraking maneuver, experimented with space domain awareness technologies, successfully tested Naval Research Laboratory technology designed to harness solar energy and transmit power to the ground, and subjected seeds to the radiation environment of space for the purpose of better understanding how to sustain humans on long-term crewed missions to the moon and beyond.

The X-37B is a dynamic and responsive spacecraft responsible for conducting a range of tests and experiments that expedite the development of critical next-generation technologies and operational concepts for reusable space capabilities.

A friend just sent me the artwork for the Boeing/AFRCO Space Vehicle Mission patch and coin and the 5th Space Launch Squadron Falcon 9 X-37B Mission patch. The coin will be released post-flight with the landing day added.

This new NGA rocket launching notice should be for this launch; there aren't any other known Florida launches within the next few days. Not exactly the most useful notice, the only zone listed is the region directly offshore of the launch pad, no downrange zones are included.

Location and direction of the Falcon 9 upper stage deorbit area in the Pacific suggests an orbital inclination of 49.5 degrees. Timing and location is consistent with a Low Earth Orbit at 350-400 km altitude, as previous OTV missions except OTV 7.

I note something odd in the quoted times of the Navigational Warning windows per date.

They shift by about 20 minutes/day, to a later time each successive day.

In order to target the same orbital plane, they should however shift towards an earlier time each succesive day.

Some space Force intern screwed up there and applied a minus sign wrong? ???

That is only for a specific plane for rendezvous

The US Space Force will be launching the OTV-8 spaceplane aboard a Falcon-9 NET August 22 0340 UTC

The booster for this flight will perform an RTLS landing at LZ-2 located at Cape Canaveral SFS

OTV will be deployed into an orbit with a Semi-Major Axis of ~6875km (~500x500km likely) with an inclination of 49.5 degrees

This OTV mission will aim to test satellite-to-satellite laser link communication (possibly Starshield)

Due to it being deployed into Low-Earth Orbit, you will be able to observe this mysterious spaceplane with the naked eye.

This mission is high in priority with Amateur Satellite Trackers, so there will likely be routine orbit determinations despite the fact that the US Space Force provides no public orbital data.

The weather looks good for this flight; Erin should be out of the area by launch time.

SpaceX is targeting Thursday, August 21 at 11:50 p.m. ET for Falcon 9’s launch of the USSF-36 mission to orbit from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida. A backup launch opportunity is available at the same time on Friday, August 22.

SpaceX’s live webcast of this mission will begin about 20 minutes prior to liftoff, which you can watch here and on X @SpaceX. You can also watch the webcast on the new X TV app.

This will be the sixth flight for the first stage booster supporting this mission, which previously launched NROL-69, CRS-32, GPS III-7, and two Starlink missions. Following stage separation, the first stage will land on SpaceX’s Landing Zone 2 (LZ-2) at Cape Canaveral Space Force Station in Florida.

USSF-36 is the eighth launch of the X-37B Orbital Test Vehicle (OTV-8) and third Falcon launch of the spacecraft, after SpaceX previously launched OTV-5 and OTV-7 (USSF-52).
