Since its opening, and until recent years, our Zeiss Model VIa optical planetarium projector has brought the wonder of the night sky to countless visitors. The Zeiss Company no longer services the over 40 year-old model, and though its stars are as sharp as ever, and its skies deep in their dramatic blackness, its celestial motors have become weary, so it has been retired in favor of an ever-improving digital projection system that offers many advantages to meet modern programming needs. The Albert Einstein Planetarium theater itself is also closing as our multi-year renovation progresses through the Museum, but it will eventually reopen as a fully digital experience. Now that we are saying good-bye to its original projector, the Zeiss Model VIa, the question is, of course, how did it get here
On April 6, 1917, the United States entered World War I, setting America on a course to become an important player on the world stage. It was a turning point in the nation’s history that still reverberates through world events a century later. One of the Museum’s most engaging programs in observance of the hundredth anniversary of the First World War is Hollywood Goes to War: World War I on the Big Screen, a year-long film series showing Hollywood’s finest feature films on World War I.
We recently took new photographs of the Mercury Friendship 7 spacecraft following its conservation. This is the same spacecraft that John Glenn piloted into Earth orbit, an American first. The images reveal details of the spacecraft that can be easy to overlook when taking the capsule in as a whole. Are you able to pinpoint the circles in the capsule's heat sheild where NASA extracted samples to test durability? Or what about the eye chart inside the capsule that John Glenn was asked to use to test his vision?
Conservator Amanda Malkin has spent the last year examining, documenting, and conservering the Museum's 20 nineteenth century Chinese kites. Malkin shares how the traditional kites were constructed from the multiple thicknesses of split bamboo to the plant fibers that make up the Chinese paper. She also documents her conservation process for one of the treated kites, including the delicate process of removing brown craft paper tape.
Following the Apollo 1 fire, James Webb, the administrator of NASA, asked President Johnson to conduct an investigation of the tragedy. Johnson agreed and an independent review board was convened. Among the six factors found to contribute to the Apollo 1 fire, one was the lack of a quickly removable hatch. Curator Allan Needell uses hatches from the Museum’s collection to illustrate the changes that were made to the hatch system following Apollo 1 to improve safety.
The breakout movie Hidden Figures tells the story of three African American women who worked as mathematicians at NASA. The story sheds light on the significant contributions of the three women—Katherine Johnson, Dorothy Vaughan, and Mary Jackson—but also the broader impact that women had behind the scenes at NASA.
Johnson, Vaughan, and Jackson all began their careers at the National Advisory Committee for Aeronautics (NACA)—which later became NASA—working as “computers.” Computers were not what we think of them today. They were people, primarily women, who reduced or analyzed data using mechanical calculators—we’ve previously explored the role of computers in astronomy.
As a photographer at the Museum, my job is to make our artifacts stand out in images. This can be a challenge with the type of lighting in our galleries and the limited amount of time I have to shoot before the Museum opens. Over the years, however, I’ve found ways to optimize the lighting and my time to achieve my goals.
Captain Eugene Andrew Cernan died Monday, surrounded by his family in Houston, Texas. He was 82 years old. For more than half his life, he was known as the Last Man on the Moon, but he was also a devoted father and husband, a naval aviator and advocate, and a great friend to many. He remains a hero for the ages.
“Gene” Cernan will always be remembered as the “last man on the Moon”—at least until the next person walks there. As commander of Apollo 17, the final expedition of that program, he spent three days on the Moon with Harrison “Jack” Schmitt. Yet that is not all he accomplished in a storied astronaut career.
At the Observatory, we often get the question “What telescope should I buy?” But once you have one, what do you do with it? Maybe it’s still in the box, perhaps you found it frustrating to use, or maybe you’re ready to hunt for more advanced targets. If that sounds like you, it’s time to go to a telescope clinic!
