Marshall graduate student researcher Juliana Neves, who is pursuing her doctorate in civil engineering at Pennsylvania State University, monitors cement paste samples returned from space as part of the Microgravity Investigation of Cement Solidification. Neves, investigators at Penn State and Marshall researchers led by NASA materials scientist Richard Grugel mirrored each sample experiment conducted on the International Space Station -- 120 tests on the ground, 120 in orbit -- and will continue to assess their findings in months to come.
