Kristine Davis, a spacesuit engineer at NASA’s Johnson Space Center, wearing a ground prototype of NASA’s new Exploration Extravehicular Mobility Unit (xEMU), is seen during a demonstration of the suit, Tuesday, Oct. 15, 2019 at NASA Headquarters in Washington. The xEMU suit improves on the suits previous worn on the Moon during the Apollo era and those currently in use for spacewalks outside the International Space Station and will be worn by first woman and next man as they explore the Moon as part of the agency’s Artemis program.

Dr. David Brown (right), a NASA astronaut, poses with students in the gymnasium of Ronald McNair Magnet School in Cocoa, Fla. From left, the students are Kristin Rexford, Danitra Anderson, Dominique Smith, Fallon Davis, and Qiana Taylor. Brown was at the school to attend a tribute to NASA astronaut Ronald McNair. The school had previously been renamed for the fallen astronaut who was one of a crew of seven, who lost their lives during an accident following launch of the Space Shuttle Challenger in January 1986
