field of view. This provided important political momentum to the project, even though the telescope represents only a modest fraction of the cost of the mission and the boundary conditions from the NRO design may push the total cost over that of a fresh design. This mission concept, called WFIRST-AFTA (Astrophysics Focused Telescope Assets), was matured by a scientific and technical team; this mission is now the only present NASA plan for the use of the NRO telescopes. The Roman baseline design includes a coronagraph to enable the direct imaging of exoplanets. Several implementations of WFIRST/Roman were studied. These included the Joint Dark Energy Mission-Omega configuration, an Interim Design Reference Mission featuring a telescope, Design Reference Mission 1 with a 1.3 m telescope, Design Reference Mission 2, with a telescope, and several iterations of the AFTA configuration. In the 2015 "Final" report, Roman was considered for both geosynchronous and L2 orbits. L2 has disadvantages versus geosynchronous orbit in available data rate and propellant required, but advantages for improved observing constraints, better thermal stability, and more benign radiation environment. Some science cases (such as exoplanet microlensing parallax) are improved at L2, but the possibility of robotic servicing at either of the locations is currently unknown. By Feb 2016 it had been decided to use a halo orbit around L2. The project is led by a team at NASA's Goddard Space Flight Center in Greenbelt, Maryland. On 30 November 2018, NASA announced it had awarded a contract for the telescope. This was for a part called the Optical Telescope Assembly or OTA, and runs to 2025. This is in conjunction with the Goddard Space Flight Center for which the OTA is planned for delivery as part of this contract. A February 2019 description of the mission's capabilities is available in a white paper issued by members of the Roman team. Science objectives The science objectives of Roman aim to address cutting-edge questions in cosmology and exoplanet research, including: Answering basic questions about dark energy, complementary to the European Space Agency (ESA) Euclid mission, and including: Is cosmic acceleration caused by a new energy component or by the breakdown of general relativity on cosmological scales? If the cause is a new energy component, is its energy density constant in space and time, or has it evolved over the history of the universe? Roman will use three independent techniques to probe dark energy: baryon
