The media are invited to attend a briefing by NASA astronaut Barry “Butch” Wilmore during his visit to Glenn Research Center in Cleveland. Wilmore, who returned from the International Space Station in March 2015, will share his experiences in space with the Glenn workforce during an hour-long briefing, starting at 1:30 p.m., Oct. 21. A media availability will immediately follow.

On Sept. 25, 2014, Wilmore and two cosmonauts launched aboard a Russian Soyuz rocket as members of Expedition 41. Wilmore served as a flight engineer until November, when he assumed command of the station upon arrival of the Expedition 42 crew. He returned to Earth on March 12, 2015. During his mission, he logged 167 days in space and performed four spacewalks totaling 25 hours, 36 minutes. While on the station, Wilmore performed fluid and combustion experiments that were developed by Glenn researchers.

A veteran of the Space Shuttle Program, Wilmore piloted STS-129 in 2009. He has accumulated a total of 178 days in space.

The International Space Station is a convergence of science, technology and human innovation that enables us to demonstrate new technologies and make research breakthroughs not possible on Earth. It has been continuously occupied since November 2000. The space station remains the springboard to NASA’s next giant leap in exploration, including future missions to an asteroid and Mars.

Media representatives interested in attending the briefing must contact Jan Wittry by email at or by phone at 216-433-5466 by 1 p.m. Oct. 20 to arrange for required NASA security clearances.
