Labor Day became a national holiday in the United States in 1894, codifying what had become an American tradition of celebrating the work of labor unions with parades, picnics, and other festivities. During the 1920s and 1930s, the National Air Races were also becoming a Labor Day tradition, often held in Cleveland, Ohio.

The experimental helmet, worn by famed American aviator Wiley Post to test the limits of high-altitude flying, can normally be seen at the Smithsonian Institution Building (The Castle) on the National Mall in Washington, DC. When white corrosion deposits were noticed on the metal, however, the helmet was removed for examination and treatment. It was sent to the Museum’s Emil Buehler Conservation Laboratory in Chantilly, Virginia.

The National Air and Space Museum's full-scale mockup of the Pioneer 10 spacecraft was recently moved to its new location in the Boeing Milestones of Flight Hall as a part of a major renovation to the gallery.

When most people think of emergency fixes in space, the first incident that comes to mind is the famous Apollo 13 mission. The astronauts fashioned duct tape and surplus materials into air filtration canisters in the lunar module to keep all three astronauts alive for the entire trip home.

Gene Kranz is best known for his stellar performance as flight director for the ill-fated Apollo 13 mission. But Kranz is also known for another thing: his white vests. Kranz’s vests had legendary status around mission control, and also in the minds of the public after actor Ed Harris wore an exact replica of Kranz’s most famous vest in the 1995 movie, Apollo 13. Kranz’s vests represented the strong and can-do approach that pervaded his mission control team, especially during the Apollo 13 mission in which the astronauts’ lives were at stake.

For the past decade, SpaceShipOne has been on display as one of the hanging artifacts in the Boeing Milestones of Flight Hall. It was specifically positioned to depict the aircraft in its initial stage of powered flight (30 degrees, nose up attitude) just after release from its White Knight mother ship, which carried it aloft to an altitude of about 14,326 meters (47,000 feet). In March of this year, SpaceShipOne was lowered to the floor as part of a major renovation of the Milestones gallery. During this time, it received a thorough condition assessment and photo documentation by conservator Sharon Norquest. After surface cleaning and minor conservation work is completed, it is scheduled to be rehung this week and will be one of the major artifacts in the new Boeing Milestones of Flight Hall, scheduled to open in July 2016. The renovation project provided us with a unique opportunity to consider how we showcase SpaceShipOne in the future.

On July 13 and 14, I was invited to visit the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, for the New Horizons Pluto Flyby Events.

On July 14, the New Horizons spacecraft completed a 9.5-year-long, 4.8-billion kilometer (3-billion mile) journey to the object furthest from the Sun to be visited by a spacecraft.

Through the commotion of a very successful July which included the New Horizons mission to Pluto, the 40th anniversary of the Apollo-Soyuz Test Project, the 46^th anniversary of Apollo 11, and the Museum’s very first Kickstarter project, there is one anniversary that we may have inadvertently overlooked. In July, the Zvezda (Russian for “star”) module of the International Space Station (ISS) celebrated 15 years in orbit.

There's more to these suits than meets the eye.
