KENNEDY SPACE CENTER, FLA. -- Sergio De Julio (at right), president of the Italian Space Agency, Agenzia Spaziale Italiana (ASI), shakes the hand of NASA Adminstrator Daniel S. Goldin while holding the document which signifies the transfer of the "Leonardo" Multipurpose Logistics Module (MPLM) from ASI to NASA. The ceremonial event was held in the Space Station Processing Facility beside Leonardo. The MPLM, a reusable logistics carrier, will be the primary delivery system used to resupply and return International Space Station cargo requiring a pressurized environment. Leonardo is the first of three MPLM carriers for the International Space Station. It is scheduled to be launched on Space Shuttle Mission STS-100, targeted for April 2000

Marshall Space Flight Center Director Todd May introduces NASA Acting Adminstrator Robert Lightfoot prior to his delivery of the "State of NASA", February 12, 2018, at the Marshall Space Flight Center in Huntsville, Alabama. In his address, Lightfoot discussed what the President's Fiscal Year 2019 budget request means for America's space agency. According to Lightfoot, it "reflects the administration's confidence that America will lead the way back to the Moon and take the next giant leap". Lightfoot delivered the "State of NASA" address in Marshall's Center for Advanced Manufacturing where engineers are pushing boundaries in the fields of additive manufacturing, 3D printing, and more. Hardware for NASA's Space Launch System and a model of the agency's Orion spacecraft served as a backdrop for the annual event. SLS, which is managed by Marshall, will enable a new era of exploration beyond Earth's orbit by launching astronauts on missions to deep-space destinations including the Moon and Mars.
