Do You Want to Build a Snowman?

Posted on


Washington, DC, always awaits its first real snow day with anticipation and trepidation. I was curious what the National Air and Space Museum collections had in the way of snow activities. I learned that the Museum has Charles Lindbergh’s snowshoes and sled; in the photo archives, I found the usual snowy vista backgrounds with airplanes in the foreground; and then I came across a classic snowman pose with a twist!

In his memoir, Gatchina Days: Reminiscences of a Russian Pilot, Alexander Riaboff recalls training in 1916 at Russia’s Gatchina Military Flying School, just south of St. Petersburg. Flying obsolete pre-war Farman aircraft was dangerous. Riaboff remembers accidentally crashing his aircraft on his first flight, since he wasn’t really supposed to take off and hadn’t yet learned to land. Crashes were frequent and several of his classmates did not survive the cadet program.

Although the cadets were training for a serious purpose, their days were not without light-hearted moments. Riaboff writes of holding a massive party celebrating a promotion that disturbed the neighbors. His photo collection, in the National Air and Space Museum Archives, contains a photograph of snowman caricatures of Austro-Hungarian Emperor Franz Joseph I and Germany’s Kaiser Wilhelm II. I especially like the stylish snow pickelhaube and twig mustache!

Enjoy the winter and best of luck trying to get a certain song out of your head!

Obscure Objects: Tom Stafford’s Jingle Bells and Wally Schirra’s Harmonica

Posted on


It is not unusual for astronauts who find themselves in space around December 25 to display a little holiday spirit. Gemini VI astronauts Tom Stafford and Wally Schirra were no exception.

Gemini VI was originally scheduled to launch on October 25, 1965 and dock with the unmanned Agena Target Vehicle, but the flight was canceled after the target vehicle blew up shortly after its launch. The mission was quickly changed to a rendezvous with Gemini VII, which would carry Jim Lovell and Frank Borman on a long endurance flight. Gemini VII was launched for its 14-day mission on December 4, 1965.

On December 12, the renamed Gemini VI-A launch attempt ended in a frightening engine cut-off on the pad. Thanks to the crew’s coolness, they did not eject, which would have ruined the spacecraft and endangered the astronauts’ lives. Their second launch attempt on December 15 was a success.

On that date, Gemini VI-A pulled within 0.3 meters (1 foot) of Gemini VII. It was the first time in history that two vehicles had maneuvered to meet in space for a rendezvous. They flew in formation for about five hours. Then, just before Gemini VI-A was set to reenter Earth’s atmosphere December 16, Tom Stafford made a radio transmission:

“We have an object, looks like a satellite going from north to south, probably in polar orbit….very low, looks like he might be going to re-enter soon….Standby one, you might just let me try to pick up that thing.”

At that point, the sound of a tiny harmonica, accompanied by small sleigh bells, could be heard playing the well-known holiday tune, “Jingle Bells.” Schirra played the harmonica, while Stafford jingled the bells. It was the first musical interlude from space. Hear the transmission.

“Wally came up with the idea,” Stafford told Smithsonian magazine for a 2005 article. “He could play the harmonica, and we practiced two or three times before we took off, but of course we didn’t tell the guys on the ground. We never considered singing, since I couldn’t carry a tune in a bushel basket.”

The two astronauts had prepared for the performance by attaching dental floss and Velcro to the instruments so they could be hung on the wall of the spacecraft when not being used.

Stafford and Schirra donated the instruments to the National Air and Space Museum in 1967. They are on display in the Apollo to the Moon exhibition in the Museum in Washington, DC.

Keeping Watch on Venus

Posted on

Venus has almost the same diameter as the Earth and is the next closest planet to the Sun. The similarity ends with the weather report, however. The surface temperature is more than 465 o C (870o F) and atmospheric pressure is 90 times that of Earth. The surface is hidden from view by a dense blanket of clouds, so we must use radar systems to “see” the landscape below. Using a data processing technique called synthetic aperture radar, these systems create images that reveal information of great interest to geologists: how much rocky material is scattered across the surface, how thick is any dust layer, and what kinds of mountains, volcanoes, folds, or ridges exist?

In the early 1990s, the Magellan spacecraft mapped nearly the entire planet with a resolution that could pick out features about the size of a football field. Even with this global view, there is much we do not understand about Venus, especially about what goes on at the surface. With such a large planet there is plenty of internal heat, so we expect that volcanoes might erupt, but Magellan could not linger in orbit long enough to watch for such changes. Since that time, Venus has kept its secrets, visited by the European Venus Express Mission but not mapped again by an orbiting radar sensor. Instruments on Venus Express can get a blurry view of the ground by imaging narrow bands in the electromagnetic spectrum where the atmosphere lets heat escape from the surface. From these maps, some volcanic areas seem to be less weathered than others, perhaps indicating more recent eruptions. The exact nature of what is happening cannot be understood without a long-term comparison between images that reveal the landscape in much finer detail.

Maps of Venus collected using Earth-based radar systems in 1988 and 2012. Smithsonian Institution

Earth-based radar astronomy may fill that gap in our monitoring of Venus. In 1988, a team led by Donald Campbell of Cornell University used the radar system at Arecibo Observatory in Puerto Rico to map the side of Venus that faces Earth when the two planets are closest together in the sky (called an inferior conjunction). This map can distinguish features about a mile across—less detailed than Magellan but still adequate to see large lava flows from volcanoes. In 2012, a team led by Smithsonian scientists carried out a similar type of mapping, transmitting the radar signal from Arecibo Observatory but receiving the echoes from Venus at the Green Bank Telescope in West Virginia.

The area covered is about 3600 km (2237 miles) across. The impact craters Stuart, Peggy, and Nadia are labeled. Fine-grained material from Stuart crater darkens both radar images within the white outline, but in the Earth-based view can be seen extending well into the highlands (orange outline).

It is painstaking to compare these images and search for evidence of change, but the work is ongoing. In the meantime, combining images from the two observing periods is yielding a wealth of insight about other processes that alter the surface of Venus. One source of change is through the formation of impact craters, which hurl dusty material above the atmosphere, from where it settles back to the surface up to hundreds of miles away. Over time, the gentle surface winds move this material around, piling it up against ridges or hills. The Earth-based data show that such blankets of fine material can cover large regions of the fractured, mountainous uplands called tesserae. These rugged highlands are likely places to find rocks that record the early history of Venus, and some evidence suggests that the tesserae share similarities with continents on Earth. Mapping the extent of crater deposits and other types of surface change will be crucial to finding the best landing sites for future spacecraft that venture into this very “unearthly” environment.

Orion Test Flight: Back to the Future

Posted on

If weather permits and no last-minute technical issues arise, NASA’s next-generation crew exploration vehicle launches into space for the first time on December 4*, 2014. The engineering test flight with no one aboard the craft is planned to last four hours, make two orbits at a distance of 3,600 miles, and splash down off the coast of Baja California. The flight will test basic spacecraft systems and new safety measures.

Orion

Some have called Orion “Apollo on steroids” because the large conical capsule is reminiscent of the Apollo command modules that took men to the Moon and back. Scaled up to seat four crewmembers, Orion has a crew escape system for use in a launch mishap. The craft descends from orbit protected by a blunt ablative heat shield and slowed by three huge parachutes like those used before the shuttle era.

The launch vehicle for this test flight is the Delta IV Heavy from United Launch Alliance, routinely used to place satellites into orbit. A new Space Launch System (SLS) under development will eventually come into service for Orion; it also draws elements from the past—derivatives of the Saturn V and space shuttle liquid propellant engines and scaled-up shuttle solid rocket boosters.

NASA is billing this flight as the first step in the journey to Mars, and Orion as the spacecraft built to take humans farther than they have ever gone before. It may be a decade or longer before a Mars mission happens, as there is not yet an official program with funding in place. However, sending the vehicle far beyond the International Space Station’s 250-mile orbit to check out its performance in the harsher radiation environment and the higher speed reentry is a prelude to long-distance exploration.

The Museum has three distinctive links to Orion. One is Chief Engineer Julie Kramer White, who was our liaison to NASA for shuttle test vehicle Enterprise. Based in the orbiter engineering office in Houston during the 1990s, she arranged for various inspections on the original orbiter to evaluate the condition of its aging materials. To our knowledge, she is the first female chief engineer for the development of a crew spacecraft.

Another connection to Orion is that a few mementos from the Museum are on this flight. We sent three small silk flags with our vintage logo, previously flown on Discovery’s first mission in 1984; two small “Web of Space” sculptures by local artist John Safer that we award as the Museum’s annual trophy for current and lifetime achievement in aerospace; and an unflown oxygen hose from our inventory of spare Apollo spacesuit parts.

Our strongest connection to Orion is our relationship with Lockheed Martin, developer of the new spacecraft and one of the Museum’s most generous supporters. The Lockheed Martin IMAX Theater and our partnership in producing the first three IMAX® films made in space are just two of the most visible emblems of this long and valued relationship.

The Museum plans a launch and return watch program in the Moving Beyond Earth exhibition gallery, using the wall-size screens to give viewers a close look at these events. There we tell the shuttle and space station stories and set the scene for the future of human spaceflight. That future, whatever it may hold, begins with Orion. The Museum’s staff sends all best wishes to NASA, Lockheed Martin, United Launch Alliance, and the entire Orion team for a successful first test flight.


*The first launch attempt on December 4 was briefly postponed by high winds and then scrubbed when technical issues arose that could not be resolved within the four hour launch window. Launch was rescheduled to December 5.

Making Moves in Milestones

Posted on

If you visit the Museum in Washington, DC, you may notice a few key objects have been removed from display. The last several weeks have been especially busy for our Collections Processing Unit. More than 15 objects have already been moved as part of the major renovation of the Boeing Milestones of Flight Hall—scheduled to open on the Museum’s 40th Anniversary in 2016. Recently, Sputnik 1, Explorer I, Pioneer 10, Mariner 2, and the Goddard Rockets have all been delicately removed from display and transported offsite to the Steven F. Udvar-Hazy Center for conservation.

Anthony Wallace, a supervisory museum specialist with the Collections Processing Unit, shared some of the logistics involved with moving the Museum’s treasured artifacts. “Moving anything from downtown [Washington, DC] is always complex,” he said.

Hours (upon hours) of work will go into preparing for a single artifact move. From constructing crates and specialized handling gear that accommodate each artifact’s unique measurements to making sure the right equipment will be available. And there’s also coordinating with the Museum’s many departments and staff: curators, conservation, exhibition specialists, security, and photographers among many.

Sputnik 1

According to Anthony, moving Sputnik 1 and Explorer I were fairly straight forward. For both, the most difficult task was determining how each was installed so that they could be efficiently uninstalled. In total, Anthony estimates it took about four staff hours to remove Sputnik 1 and Explorer I, once they were in the Museum, with another two hours of work to secure the objects for transport. Everything took place before the Museum opened to the public.

Mariner 2

Several days later, Pioneer 10 and Mariner 2 were removed. As larger objects, extra steps were required. Pioneer 10, for example, had to be transported in pieces thanks in large part to its 2.7-meter (9-foot) dish. Small parts were removed while the object was still hanging in the gallery. Chain hoists were used to lower the main bus to the ground where it was mounted to a specially built transport pallet.

Finally, the Goddard rockets were removed from display. Two of the rockets were removed in the morning prior to the Museum opening. The largest rocket needed more time and logistics to remove so this work was done in the evening after closing. Due to its vertical position directly beneath the North American X-15, the rocket needed to move out to the center of the gallery so staff could successfully rotate it from the vertical to the horizontal position for transport. The rocket was driven on a forklift and in combination with a chain hoist, the 8-meter (26-foot) tall assembly was rotated into its transport orientation. Visitors familiar with the exhibition space will notice that the Viking Lander now occupies the spot where the Goddard rockets were displayed.

In the next several months, more objects will be on the move—Anthony noted the Lunar Module (LM-2) would pose a particularly interesting challenge. The LM-2 will be moved from the east end of the building, where it has been displayed since 1976, and become a focal point of the newly renovated Hall. Due to the size of the lander, its ascent and descent stages will be separated for the move. Moving the Lunar Module, as with all of our artifacts, will give us the opportunity to get up close to examine, clean, and photograph portions of the object that are not typically accessible.

Curious about what it takes to coordinate a project like this? Ask Anthony and other Milestones team members on the Boeing Milestones of Flight Hall renovation website. You can also follow our progress on Twitter using #MilestonesofFlight.
