After her death, the Maria Goeppert Mayer Award was created by the American Physical Society to honor young female physicists at the beginning of their careers. Open to all female physicists who hold Ph.D.s, the winner receives money and the opportunity to give guest lectures about her research at four major institutions. Two of her former universities also honor her. The Argonne National Laboratory presents an award each year to an outstanding young woman scientist or Engineer, while the University of California, San Diego hosts an annual Maria Goeppert Mayer symposium, bringing together female researchers to discuss current science. Crater Goeppert Mayer on Venus with a diameter of about 35 km is also named after Goeppert-Mayer. In 2011, she was included in the third issuance of the American Scientists collection of US postage stamps, along with Melvin Calvin, Asa Gray, and Severo Ochoa. Her papers are in the Geisel Library at the University of California, San Diego, and the university's physics department is housed in Mayer Hall, which is named after her and her husband.
