During the spacewalk, Onufrienko and Bursch installed six deflector shields for the Zvezda Service Module's jet thrusters.

During the IVA-commanded re-deploy of the solar array, several array panels snagged and were damaged, requiring an unplanned spacewalk to successfully repair the array.

During the 12 minute spacewalk the two crew members moved a docking mechanism to accommodate the MRM-2.

During this spacewalk, Sharipov and Chiao deployed a small Russian experiment called Nanosatellite.

During the five-day mission his primary task was to assist in the deployment of the Chandra X-Ray Observatory, and to conduct a spacewalk if needed.

During the spacewalk, Tokarev and McArthur relocated a boom adapter for the Strela, a Russian hand-operated crane, from the Zarya module to Pressurized Mating Adapter 3.

During World War II, the company diverted several resources to support the war effort and relinquished its West Coast markets to conserve rail car space.

During this period, a method of manufacturing many interconnected transistors in a compact space was developed.

During 1960, all of its civilian space programs were transferred to the National Aeronautics and Space Administration ( NASA ) and the military space programs to the individual Services.

During an international space symposium in May 1966, attended by space scientists from the United States and Soviet Union, he first proposed that manned landings on the moons would be a logical step after a manned landing on the Earth's moon.

During the first decade of operation of the Internet ( by the late 1980s ), it became apparent that methods had to be developed to conserve address space.

During an emergency mission in space, the X-Men find their shuttle damaged.

During World War II, Camp Maxey had an area of 36, 683 Acres ( 14, 845. 08 Hectares ), and billeting space for 2, 022 Officers, and 42, 515 Enlisted Personnel.

During WWII and beyond, RCA set up several new divisions, for defense, space exploration and other activities.

During the Dominion War, Akleen's family home lay in Dominion-controlled space ; Elim Garak suggested that recapturing it would lead to a major propaganda victory for Federation forces.

During an incident in 2374, Torres confessed her love for Tom Paris to him when they were left floating in space in environmental suits, with almost no hope of rescue (" Day of Honor ").

During the autumn of 1909 Picasso sculpted Head of a Woman ( Fernande ) with positive features depicted by negative space and vice versa.

During the Shuttle era, six orbiters were built, all of which have flown in the atmosphere and five of which have flown in space.

During the first decade of the Internet after the invention of the Domain Name System ( DNS ) it became apparent that the devised system based on the classful network scheme of allocating the IP address space and the routing of IP packets was not scalable.

During the same decade, the probabilistic voting theory started to replace the median voter theory, since it clearly showed how it was able to find Nash Equilibria also in multidimensional space.

During Johnson's administration, NASA conducted the Gemini manned space program and the Apollo program, including Apollo 7 ; and the first human spaceflight to the Moon, Apollo 8, in December 1968.

During his time at the Tsentr Podgotovki Kosmonavtov ( cosmonaut training centre ), he contributed to space vehicle design, cosmonaut training and evaluation and public relations.

During the day heat gains from the sun, the occupants of the building, and any electrical lighting and equipment, causes the air temperatures within the space to increase but this heat is absorbed by the exposed concrete slab above, thus limiting the temperature rise within the space to be within acceptable levels for human thermal comfort.

During the 1960s and 1970s, it was common belief that space hotels would be launched by 2000.
