A write up of the issue, the other issue and there wasn't much more to write about so added some historical overview of TDRS from William:
https://www.nasaspaceflight.com/2017/07/tdrs-m-under-review-pre-launch-incident/
From the article:
Quote
The satellite carries s-band phased array antennae to allow simultaneous communications with five other spacecraft, as well as two steerable antennae providing S, Ku or Ka band coverage to spacecraft requiring communications at a higher data rate. It’s this system that is currently being reviewed due to the incident noted by NASA over the weekend.
S-band omnis are typically for command and telemetry purposes (e.g. USB during post-launch, pre-deployment), not a high data rate application.

Yes, this is an omni for spacecraft bus command and telemetry (with ground station) purposes through out all mission phases and has nothing to do with the comm package payload that is used to talk to other spacecraft.

Atlas V First Stage is Lifted for TDRS-M

A United Launch Alliance Atlas V first stage is lifted at the Vertical Integration Facility at Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida. The rocket is scheduled to launch the Tracking and Data Relay Satellite, TDRS-M. It will be the latest spacecraft destined for the agency's constellation of communications satellites that allows nearly continuous contact with orbiting spacecraft ranging from the International Space Station and Hubble Space Telescope to the array of scientific observatories. Liftoff atop the ULA Atlas V rocket is scheduled to take place from Cape Canaveral's Space Launch Complex 41 on Aug. 3, 2017 at 9:02 a.m. EDT.

So no word yet if the damaged antenna will cause a launch delay?

TDRS-M Status Update - July 20, 2017
NASA and Boeing are reviewing plans to safely replace an antenna on the Tracking and Data Relay Satellite (TDRS-M). The satellite’s Omni S-band antenna was damaged during spacecraft closeout activities July 14 at Astrotech Space Operations in Titusville, Florida. The TDRS team is also evaluating a possible electrostatic discharge event involving spacecraft mechanical ground support equipment at the launch site. An integrated launch team is assessing the Aug. 3 launch date on an United Launch Alliance (ULA) Atlas V rocket from Cape Canaveral Air Force Station in Florida. TDRS-M is the latest satellite to support the space segment of NASA’s Space Network.

Re ##TDRSM before you ask, yes there are 2 S-band antenna's, it was not mentioned which 1 was damaged,this is the other one,take your pick..[last 2 photos]

TDRS-M Status Update – July 21, 2017
Posted on July 21, 2017 at 5:12 pm by Amber Philman.

NASA, Boeing and United Launch Alliance (ULA) are reviewing a new launch date in August for the agency’s Tracking and Data Relay Satellite (TDRS-M). NASA and Boeing need additional time to replace the spacecraft’s Omni S-band antenna at Astrotech Space Operations in Titusville, Florida. A separate possible ground support equipment issue at Astrotech still is being assessed. TDRS-M will launch on a ULA Atlas V rocket from Cape Canaveral Air Force Station in Florida. It is the latest satellite in a fleet of satellites supporting the space segment of the NASA’s Space Network.

Not official, but we understand they are looking at August 10 NET, pending final reviews. This was CRS-12 Dragon's previous launch date. NASA decided TDRS has priority.

NSF experts, please correct if I'm wrong:

Currently, it takes approximately 3 days to reconfigure the launch range between Canaveral/KSC launches.  Correct?

Some, but not all United States launches use TDRSS during launch.  Atlas V/Delta IV: yes; Falcon 9: no?
***

Launching TDRS-M from Canaveral on 8/10, followed by NROL-42 from Vandenberg, on 8/14, both on Atlas V's, is eminently do-able, yes?

Launching NROL-42 on Atlas V, from Vandenberg on 8/14, followed by launching Dragon, on Falcon 9, from KSC later on the same day--also possible?  No interference between the launch assets?

Are there any personnel that will work 2, or all 3, of these launches?

Thank you in advance!

EDIT: left a date out, EDITed it in.

Seeking clarification on 3., if you are free to comment:

Will the TDRS-M launch be further delayed? Or will the NROL-42 launch be delayed?

And a further question:
6. What is the approximate least amount of time possible between 2 ULA launches: 1 on the east coast, 1 on the west coast?

Thank you!

I don't have a further slip yet, but it was always the risk, especially if NASA thinks they've (AstroTech I assume) really messed this up they want even more work doing.

I thought Astrotech was responsible for the damage and now the replacement of the omni antenna?
