    It is my pleasure to announce that Mirror Technology Days 2021 will be held Tuesday Nov 2nd to Thurs Nov 4th at the Holiday Inn Downtown, Rochester NY.

    Approval for In-Person Meeting
    NASA has approved Tech Days as an in-person meeting with the following COVID protocols:

    • Proof of vaccination is required
    • Face masks are required
    • Social distancing is required (we plan 2 chairs per table and a spread of chairs in back)
    • Attendees pledge not to attend if they are not feeling well, experiencing symptoms of COVID
    • Hotel follows all CDC guidance including hand sanitization stations (which they do).

    So, we are moving forward with an in-person meeting with presentations and tours. At the same time, we are still protected. Our contract with the Holiday Inn allows cancellation in case of a new COVID surge (or other pandemic), Federal Government shutdown, etc.

    Currently, we have a preliminary agenda of 40 OPEN Presentations on Tuesday/Wednesday and 22 ITAR Presentations on Thursday. Eight more presentations are pending acceptance.

    Download preliminary agenda

    The agenda will change over the next few weeks, IF:

    • Presentations move between OPEN/CLOSED
    • Pending Presentations are confirmed.

    NOTE: schedule constraints may force some pending presentations to poster format

    Presentation Submission

    For OPEN Presentations: I will be sending more information soon about whether or not we will have a particular process for submitting OPEN presentations.

    For CLOSED Presentations: You can send them to me via encrypted email, DVD/CD or protected memory stick. 

    SPIE Digital Library  
    We will use the SPIE Digital Library to collect and archive OPEN presentations. SPIE will provide specific information about how to format your presentation for submission and publication.

    L3Harris is offering tours of the Roman Space Telescope assembly activity, including (based on availability): Primary Mirror Assembly and Telescope Structure Sub-Systems.

    • Tours will be on Monday November 1 starting at noon, running 20 minutes and ending at 3:00 PM.
    • Are limited to US Persons (i.e. US Citizens and Green Card Holders)
    • Require a Visit Authorization Form submitted to L3Harris by 27 September.

    POC for submitting forms is: Judy Luciano;; 585-269-7391.

    For more information contact   Additionally, I expect that other Rochester-based companies and educational and research institutions will offer tours.

    Attending ITAR Sessions

    The Tech Day ITAR Sessions are open to all USA Persons (citizens and green card holders). Because we are in a hotel venue this year, we will need to check ITAR eligibility on-site at the registration table. Documentation which qualifies you to attend the ITAR session includes: US Passport, US Government Civil Servant ID, copy of Birth Certificate, Green Card, or Visit Authorization letter from your Security Officer. 

    Thank you for your support of Tech Days.
