NASA Roman Space Telescope Wide Field Instrument Poster

The Roman Space Telescope (RST) is a NASA mission scheduled to launch in the mid-2020s. RST is designed to study dark energy, dark matter, and exoplanets. The Wide Field Instrument (WFI) is one of four instruments on RST. WFI will be used to survey the sky in visible and near-infrared light.

The WFI poster (PDF) provides an overview of the instrument’s design, capabilities, and science goals. The poster includes the following information:

  • Introduction: The WFI is a 2.4-meter diameter telescope with a 2.2-square-degree field of view. It will be the largest and most sensitive visible and near-infrared telescope ever flown in space.
  • Design: The WFI is a Ritchey-Chrétien telescope with a three-mirror design. The primary mirror is made of beryllium and the secondary mirror is made of silicon carbide. The telescope is mounted on a lightweight carbon fiber truss.
  • Capabilities: The WFI will be able to observe objects over a wide range of wavelengths, from visible light to near-infrared light. It will have a resolution of 0.1 arcseconds and a sensitivity of 2 nanomaggies.
  • Science goals: The WFI will be used to address a number of important scientific questions, including:
    • The nature of dark energy
    • The properties of dark matter
    • The formation and evolution of galaxies
    • The search for exoplanets

The WFI is a key instrument for the RST mission. Its wide field of view and high sensitivity will allow it to survey the sky in unprecedented detail, uncovering new insights into the universe.

Additional information

  • The WFI is being built by a team led by the Jet Propulsion Laboratory (JPL).
  • The WFI is expected to be completed in 2025.
  • The RST mission is expected to launch in 2027.
