CLEVELAND — NASA Astronaut Doug Wheelock, who completed a six-month stay in space last year, will be the guest speaker at two programs at NASA’s Glenn Research Center in Cleveland on Monday, May 23.

At 10:30 a.m., Wheelock will speak to students and educators from Cleveland area schools about how each of us can foster innovation and dream big when planning one’s education and career path. The students are from Caledonia Elementary, Michael R. White Elementary, Orchard STEM School and Shaw High School.

At 1:30 p.m., Wheelock will share his NASA experiences and highlights of his time aboard the International Space Station during Expeditions 24 and 25 with Glenn employees.

Wheelock’s visit to Glenn originally was set for February, but was postponed because of inclement weather.

Reporters interested in attending the programs or the informal media opportunity following each program must contact Sandra Nagy at 216-433-9079 or the Glenn Media Relations Office at 216-433-2901 by 4 p.m. Friday, May 20 to obtain security clearance. Both programs will be held in the Administration Building Auditorium.

Wheelock flew aboard the Soyuz TMA-19 spacecraft in June 2010 and served as an Expedition 24 flight engineer on the space station. On Sept. 22, 2010, he assumed command of the station and Expedition 25 crew. On Nov. 25, 2010, Wheelock and two of his fellow crewmembers safely landed their Soyuz spacecraft in Kazakhstan. The mission duration was 163 days.

During this expedition, more than 120 microgravity experiments in human research; biology and biotechnology; physical and materials sciences; technology development; and Earth and space sciences were conducted aboard the space station.

Wheelock also responded to an emergency shutdown of half of the station’s external cooling system and supported three unplanned spacewalks to replace the faulty pump module that caused the shutdown. His efforts restored the station’s critical cooling system to full function.
