About This Article

The latest news from the Nancy Grace Roman Space Telescope Science Operations Center (SOC) at STScI 

The Roman telescope is getting assembled at Goddard. Instruments and telescope are integrated and the deployable aperture cover has been successfully installed.  The Core Community Survey Definition Committees have produced their reports and the Roman Observation Time Allocation Committee has started reviewing them. The Roman Research Nexus is in full development and testing continues. The next Roman Science Conference on "Cosmic Cartography" will be held in Baltimore on July 14-18 and abstracts are accepted until March 28.

Each tiny dot in the image at left is a galaxy simulated by the OpenUniverse campaign. The one-square-degree image offers a small window into the full simulation area, which is about 70 square degrees (equivalent to an area of sky covered by more than 300 full moons), while the inset at right is a close-up of an area 75 times smaller (1/600th the size of the full area). This simulation showcases the cosmos as NASA’s Nancy Grace Roman Space Telescope could see it. Roman will expand on the largest space-based galaxy survey like it – the Hubble Space Telescope’s COSMOS survey – which imaged two square degrees of sky over the course of 42 days. In only 250 days, Roman will view more than a thousand times more of the sky with the same resolution.Credit: NASA's Goddard Space Flight Center and M. Troxel

Roman Timeline

Roman Tools

The Roman Research Nexus  is a science platform enabling low-barrier access to cloud computing resources and Roman data. Users will be able to work individually or in teams with shared resources, and will have access to a variety of Roman software, tools, and simulated data. Science workflows made up of Jupyter notebook tutorials are provided to help get users started on planning, simulating, calibrating, and analyzing Roman observations. Open access to the Nexus will begin in summer 2025. When it opens, we encourage interested users to sign up and let us know about your experience so we can continue to make improvements during the Nexus development.

Roman I-Sim is a tool for simulating images from the Roman Wide-Field Instrument.  It uses GalSim to accurately render astronomical scenes, combined with tools like the STPSF and CRDS to faithfully simulate the Wide-Field Instrument and detectors.  It uses the rad and roman_datamodels Python packages to output data in the format suitable for processing by the Roman calibration pipeline.  It is developed on GitHub. We want to hear your experiences using it, and accept your contributions through GitHub.
