Get to know Phoebe Waterman Haas, one of the first women in the U.S. to earn a doctorate in astronomy.

An unusual looking, four-engine, single-place, 200-foot wingspan airplane called Solar Impulse is making the same journey the pioneering Cal Rodgers did in 1911.

Uncle Sam and two lovely ladies cruise serenely above the clouds — avoiding all those holiday traffic jams — in this patriotic postcard by the great postcard artist Ellen Hattie Clapsaddle (1865-1934), who had a real talent for holiday-themed airships.

Modern launch vehicles, including the recently retired space shuttle and the earlier Saturn V that took the first humans to the Moon, are among the most complex feats of engineering in human history. In the case of the Saturn V, the vehicle was longer than a football field and comprised of some 5,600,000 separate parts, all of which had to work perfectly to enable the rocket to carry out its mission.

Monday, we launched the new National Air and Space Museum website. We’ve given the site an extreme makeover and are very excited to launch this revitalized online presence. This digital “renovation” was completed in-house by our Web & New Media Department with tremendous support from many contributors and stakeholders across the Museum.

Sally Ride became the first American woman in space in June 1983. Ride’s presence on Space Shuttle Challenger was a ride into history, for it broke the gender barrier in the United States human spaceflight program.

In 1987, the historian Michael S. Sherry published a groundbreaking and controversial book titled The Rise of American Air Power: The Creation of Armageddon (Yale UP, 1987). Sherry in effect reinterpreted the history of American air power in a way that was more contextually based and fiercely critical. The result was not to every military historian’s liking because it deviated so dramatically from what was considered the master narrative of American air power, which traditionally had focused on combat tactics and weaponry, and which had neglected the broader implications of air power and its employment. Moreover, Sherry upset the “Good War” narrative (mistakenly from Studs Terkel’s ironically titled The Good War: An Oral History of WWII) that emphasizes the heroic side of war and downplays its destructiveness, death, and tragedy. Thus, The Rise of American Air Power could be seen as representative of what has been termed the “New Military History,” an attempt to bring military history into line with other academic historical endeavor.

What flies using power from the Sun, at the speed of an ultralight, on wings longer than a Boeing 777 airliner? Answer: Solar Impulse! A team of Swiss entrepreneurs, engineers, pilots, and enthusiasts began to design the Solar Impulse in 2003 with the goal to demonstrate flying day-and-night powered only by the electricity that more than 11,000 individual solar cells generate. The electricity is stored in batteries when not used, and spin the propellers on four 10-horsepower electric motors when in flight.

Given the enormous popularity of GPS among civilian users, and the critical applications for the military, it is not surprising that a large body of literature has arisen about the origins of this remarkable technology. The curators of the new Time and Navigation exhibition discuss this history, and we have illustrated it with a few select artifacts, such as the engineering model of the Navy’s NTS-2 satellite, one of the key demonstrators of the technology that led to the deployment of the GPS constellation.

What’s missing when you sit in front of a computer all day? Adventure! Luckily, three Time and Navigation photography missions took me across the country last year, giving me the chance to escape the office.
