Acting NASA Administrator Steve Jurzyck speaks during a ceremony officially naming the NASA Headquarters building in honor of Mary W. Jackson, Friday, Feb. 26, 2021, at NASA Headquarters in Washington, DC. Mary W. Jackson, the first African American female engineer at NASA, began her career with the agency in the segregated West Area Computing Unit of NASA’s Langley Research Center in Hampton, Virginia. The mathematician and aerospace engineer went on to lead programs influencing the hiring and promotion of women in NASA's science, technology, engineering, and mathematics careers. In 2019, she posthumously received the Congressional Gold Medal. Photo Credit: (NASA/Joel Kowsky)

The four RS-25 engines fired for the full-duration of 8 minutes during the test and generated 1.6 million pounds of thrust. The hot fire test is the final stage of the Green Run test series, a comprehensive assessment of the Space Launch System’s core stage prior to launching the Artemis I mission to the Moon.
