In our exhibition Time and Navigation visitors can set their watches by a working cesium frequency standard, commonly known as an "atomic clock." Before the clock was installed, we needed the frequency standard to be calibrated to the national reference time at the U.S. Naval Observatory in Washington, DC.
As the curator for the Museum’s Martin B-26B Marauder, I’ve become obsessed with the proper way to designate the name given to it by its first pilot Jim Farrell in August 1943. It all centers on the pesky use of a hyphen. Is it Flak Bait or Flak-Bait?
When visitors enter our Museum, many are awed by the number of artifacts that are on display. We’re often asked, “How do you manage to keep everything clean?” That is a terrific question, especially since there are more than 6,000 artifacts on display at any time on the floor or hanging overhead, with more being added each year. Cleaning and inspecting the artifacts is critical to preserving the Museum’s collection.
On February 11 of this year, when scientists announced that they had detected gravitational waves, I was among the thousands of people who were so excited we couldn’t sit still. This news was literally Earth-shaking! Gravitational waves are ripples in space-time, and they’re created by events like the collision of massive objects, such as black holes. So of course, being an astronomy educator, I took the first opportunity to talk about this news with visitors at the Museum. The day after the announcement, I set up our black holes Discovery Station, which uses a rubber sheet to demonstrate how space-time gets warped by massive objects. I created my own “gravitational waves” by tapping on the rubber sheet to make it vibrate, like ripples on a pond.
It’s April and baseball is back!!!
Stardate 1604.01: At 12:01 am EDT this morning, the National Air and Space Museum began breeding tribbles. This bold, innovative, not-at-all-ill-advised experiment will run for 24 hours, until 11:59 pm tonight, allowing Museum specialists to study the galaxy’s most adorable ecological disaster in greater detail than ever before.
Documented in our National Aeronautic Association collection is the 1961 All Woman’s International Air Race that ended in Nassau, Bahamas on May 29.
Women’s History Month in the United States began as Women’s History Week in 1982. The event was expanded to the entire month of March in 1987. Throughout the past month, the Smithsonian Institution and the National Air and Space Museum, have sponsored many events for Women’s History Month. On March 28, 1988, just the second official Women’s History Month, an all-female Air Force flight crew flew a Lockheed C-5 Galaxy across the Atlantic Ocean to commemorate the month.
Our Archives houses the Technical Reference Files, an important collection of aeronautical and astronautical topics comprised of 1,920 cubic feet of documents, photographs, and ephemera. This important resource is housed in vertical files and is an organic, growing collection to which material is added constantly. Recently, we came across a remarkable document in the Tech Files of the long fight against tuberculosis—shared with you today in recognition of World Tuberculosis Day.
One of the many threads in our Explore the Universe gallery is the changing role of women in astronomy over the past two centuries. In the present gallery, opened in September 2001, we examine how the role of women as astronomers has changed over time from assisting family members to leaders of research teams.
