The OSSC will hold the final meeting of the 2025 calendar year in November, and this is will be the final Newsletter until 2026.  You are encouraged to share optics related news, publications, and events with your OSSC members and friends including profiles of our Corporate Members. Additional information is available on our Newsletter Page, or you can send me an email
 
We would love to hear from you!

OSSC Meeting
12 November 2025

The Science and Development of the
Roman Space Telescope's Coronagraph Instrument


Dr. Vanessa Bailey, Dr. Eric Cady, Dr. Brian Monacelli
Jet Propulsion Laboratory

 
 
 
The Nancy Grace Roman Space Telescope Coronagraph Instrument (CGI) is a critical technology demonstrator for NASA’s Habitable Worlds Observatory. With a demonstrated visible-light flux ratio detection limit of better than 10-8, it will be capable of directly imaging both gas giant exoplanets and circumstellar disks.

CGI completed its integration and test at the Jet Propulsion Laboratory in Spring 2024 and is currently undergoing further environmental testing while integrated into the Roman Space Telescope (RST) observatory. The RST is scheduled for launch in 2026.  
This talk will review the coronagraphy science, CGI observing modes and applications, and highlight its optical alignment, integration, and thermal-vacuum test results.
 
Vanessa Bailey is an exoplanet research scientist at NASA’s Jet Propulsion Laboratory. She is a member of the science team for NASA’s Nancy Grace Roman Space Telescope Coronagraph Instrument and has also been a science team member on several other ground-based high-contrast imaging facilities including the Large Binocular Telescope and the Gemini Telescope. She received her BS from the University of Minnesota - Twin Cities and her PhD from the University of Arizona.
Eric Cady is an optical engineer in the high-contrast imaging group at NASA's Jet Propulsion Laboratory, and the lead for High-order Wavefront Sensing and Control (HOWFSC) on the Coronagraph Instrument (CGI) for the Nancy Grace Roman Space Telescope.  His research interests include coronagraphy, wavefront control systems, and starshades.  He received his B.S. in physics from Caltech in 2005 and a Ph.D. in mechanical and aerospace engineering from Princeton University in 2010.
Brian Monacelli is a principal optical engineer and technical group supervisor at NASA's Jet Propulsion Laboratory, where he led the optical assembly and alignment of the Coronagraph Instrument for the Roman Space Telescope and the SHERLOC Instrument of the Mars2020 Perseverance Rover, among other optical instruments. He teaches technicians to learn hands-on laboratory skills via the Pasadena City College Laser Technology program. He also serves on the Optics and Electro-Optics Standards Council, where he supports development of optics standards.

The NASA Habitable World Observatory
 
NASA Exo-Solar System
This months OSSC meeting features a presentation about one of the powerful instruments designed for NASA's Habitable World Observatory (HWO).  HWO will be the first telescope designed specifically to search for signs of life on planets orbiting other stars.  Read More >

Reflecting on the Loss of Mirror Tech Days — and What Comes Next

Mirror Tech Days 2025 was abruptly cancelled due to the government shutdown.  OSSC Vice President Lisa Belodoff opines on the cancellation and includes a Southern California plan to reinvigorate the event.
 

PCC MESA Sponsors November OSSC Meeting
 
The November 2025 meeting of the OSSC will be held at the Pasadena City College (PCC). The dinner is generously sponsored by PCC MESA (Mathematics, Engineering, Science Achievement) organization. MESA serves to enrich the experience of all students interested STEM (science, technology, engineering, and math) by providing academic support and a variety of community-building opportunities. Several PCC MESA students will be in attendance at the November meeting so be sure to say hello. Read More >
