The Roman Data Monitoring Tool: Automated Scientific Data Quality Checking and Anomaly Detection for Large Data - W. Schultz (STScI) et al.
(Monday, June 10, 5:30–6:30 p.m. CT)
Planned to launch in October 2026, the Nancy Grace Roman Space Telescope (Roman) is the next NASA flagship mission. Roman’s primary objective is to use the Wide Field Instrument (WFI) to survey large regions of the sky, with some surveys including regular repeat visits to probe the time domain. The eighteen detectors of WFI (16-megapixel each) will produce 11 terabytes of science data per day. Over the course of the nominal five-year mission, this will result in an order of magnitude more data than the entire existing archive of all currently active NASA astrophysical flagships. All of these data must be calibrated and publicly released soon after arriving at the Science Operations Center (SOC). The Roman Data Monitoring Tool (RDMT) will enable the SOC to monitor the pixel-level quality of the WFI data. The RDMT is comprised of two components: the RDMT-local, which monitors uncalibrated science and engineering WFI data on-premises at the SOC, and the RDMT-cloud, which utilizes the Amazon Web Services commercial cloud to monitor calibrated WFI science products. We present the planned data workflow and prototypes of both components of the RDMT. The RDMT-local prototype monitors a select sub-sample of reference files, stores valuable metrics into a database, and outputs a report of the current data-quality. The RDMT-cloud prototype implements monitors like the astrometry check, which uses point spread function photometry to compare the expected and observed locations of bright stars, and logs the results in a cloud-based database. Additional monitors for both components are under development (e.g. a 1/f noise check in the RDMT-cloud). We are also developing an automated notification service for the RDMT and creating a dashboard interface for SOC instrument scientists.

Roman Space Telescope Observing Program Implementation - C. Mannfolk (STScI)
(Monday, June 10, 5:30–6:30 p.m. CT)
The Nancy Grace Roman Space Telescope will be used to survey the sky over its 5-year primary mission. The Science Operations Center at the Space Telescope Science Institute will manage the implementation of all approved Roman observing programs. Building on the processes, procedures, and software used in the management of HST and JWST observing programs, the Roman observing program implementation process has been designed to support Roman’s unique survey capabilities.

The Roman Space Telescope Science Operations Center - T. Desjardins (STScI) et al.
(Wednesday, June 12, 9:00–10:00 a.m. CT)
The Nancy Grace Roman Space Telescope (Roman) is the next NASA flagship astrophysics mission planned for launch in October 2026. With expected survey speeds approximately 1000 times faster than HST, and data rates 500 times larger than HST and 23 times larger than JWST, Roman presents new challenges in data handling, processing, and archiving. The Wide Field Instrument (WFI), the science instrument onboard Roman, provides HST-like spatial resolution between 0.48 – 2.3 microns, which complements well both HST and JWST spectral coverage, and has a field of view of 0.28 square degrees (~200 times larger than HST WFC3/IR). In addition to PI-led surveys, Roman will conduct community defined surveys, including the Core Community Surveys (CCSs). These surveys are being designed to facilitate a broad spectrum of scientific research, ranging from our Solar System to the farthest reaches of the observable universe, while addressing the science goals related to dark energy and exoplanets outlined in the 2010 decadal survey. The CCSs are being formulated through a community-driven process, with survey definitions expected in mid-2025. The Space Telescope Science Institute (STScI) in Baltimore, MD, is the Roman Science Operations Center (SOC), and is responsible for the planning and scheduling of all observations, as well as for WFI data processing and the generation of data products for WFI imaging. The SOC will also host the Roman Archive, and will make available a Roman Science Platform, which is being designed to enable community access to and efficient analysis of Roman data products in the cloud. All data products, including image-level and catalog-level products, will be made available to the community with no exclusive access period.

Exploring the early universe with future Roman Ultra Deep Field observations - A. Koekemoer (STScI)
(Thursday, June 13, 9:00–10:00 a.m. CT)
The Nancy Grace Roman Space Telescope, planned for launch later this decade, offers Hubble-quality imaging over a field of view about two orders of magnitude wider than that of HST or JWST. More specifically, the Wide Field Instrument (WFI) on Roman has an instantaneous field of view of ~1000 square arcminutes, with higher sensitivity than HST over wavelengths from the optical regime up to about 2 microns. Among the new areas of observational discovery space that could be opened up by Roman is the potential for carrying out Roman Ultra Deep Field observations, reaching UDF-quality depths up to about 30th magnitude, over degree-scale areas. This would greatly increase the discovery space for samples of high-redshift galaxies and AGN in the epoch of reionization, vastly increasing the sample sizes of these rare sources compared to previous HST results, and providing excellent complementarity with the latest JWST surveys. Moreover, targeting one or more Euclid and Rubin deep fields with Roman Ultra Deep Field observations would enable additional synergies in time-domain science and multiband imaging, all of which are crucial in expanding the discovery space of rare populations of sources in the early universe, and understanding their formation and subsequent evolution.
