The Mystery of Grey Spots on Apollo Glove

The last time Neil Armstrong's gloves and helmet were displayed, in 2012, visitors asked us about “grey spots” on the right glove. We're conducting research and examining historical documentation to find out why.

Exploring Colorado’s Great Sand Dunes: A Towering Red Planet Analog

As the National Air and Space Museum’s annual Mars Day! celebration approaches, we look to a recent research trip taken by a Smithsonian Summer Intern to investigate the similarities between some of Earth’s most amazing dunes and those found on the ruddy surface of Mars.

Gravitational Waves Face to Face

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.

Observing the Surface of Venus with the Arecibo Telescope

This past summer I had the opportunity to operate the world’s largest single-dish telescope at the Arecibo Observatory in Puerto Rico.

Arthur C. Clarke Collection of Sri Lanka Now Publicly Available

Almost a year ago, the Museum announced that it had acquired papers and artifacts of Arthur C. Clarke (1917-2008), renowned science fiction author and futurist.  Now we can share that the Archives has completed processing the collection and it is open for research. As we discussed in blogs last year, Clarke was a seminal figure of the 20th century, with his influence still evident in today’s science fiction literature; in the continuing, lively cultural interest in futurism; and, of course, in movies. His collection does what we hope for from any collection of a well-known, highly accomplished individual: to see into his or her processes of creativity and the network of family, friends, and peers that shaped their world.

Inventing Underwater Training for Walking in Space

Training underwater for extravehicular activity (EVA)—popularly known as spacewalking—is now critical for preparing astronauts to work in weightlessness. But when cosmonauts and astronauts first ventured outside their spacecraft 50 years ago, in 1965 and 1966, they had no such training. Spacewalking did not appear difficult, nor did space program officials think that underwater work was needed. In the United States, it took Eugene Cernan’s June 1966 Gemini IX EVA to change attitudes. Fighting against his pressurized suit, while trying to do work without adequate handholds and footholds, Cernan quickly became exhausted and overheated. Only afterward did NASA Manned Spacecraft Center in Houston reach out to a tiny company outside Baltimore: Environmental Research Associates, Inc. (ERA). Funded by another agency center, it had been experimenting with EVA simulation in a rented school pool on nights, holidays, and weekends. That project became the foundation for Houston’s first underwater training facility.

Apollo 11: The Writings on the Wall

Last year I wrote about the Armstrong purse, discovered by Neil Armstrong’s widow, Carol, in their home shortly after Neil’s death in 2012. That stowage bag of small (but historically significant) items from the first lunar landing was a reminder that the story of Apollo 11 continues to be told as new details emerge in unexpected places. Recently, we have again been reminded that a curator’s work is never done. During the course of a project to produce a detailed 3D model of the Apollo 11 Command Module Columbia, we were able to observe and record some hand-written notes and markings in areas of the spacecraft that have been hidden from view for more than 40 years.

Mars: One Mystery Revealed, Many More to Solve

The recent announcement by NASA that there is evidence of salty, liquid water seeping out of the ground on Mars is both exciting and scientifically puzzling at the same time. As a member of the science team for the High Resolution Imaging Science Experiment (HiRISE) camera on board the Mars Reconnaissance Orbiter (MRO), I’ve been hearing about these possible seeps, or Recurring Slope Lineae (RSL), for several years now.

Earth is Shaping the Shrinking Moon

Planetary science is one of those fields of research where you can always count on being surprised. The remarkable terrain of Pluto and Charon in images being sent back by the New Horizons spacecraft certainly qualifies. One of my all-time big surprises is from a recent discovery on an object much closer to home—the Moon.

Casting Shadows on the Moon

Much of the Moon is blanketed by a thick layer of dust, built up from the rocky surface over billions of years by the impacts of small meteorites. Hidden beneath the dust is evidence of ancient geologic activity – great volcanic eruptions, tectonic shifts in the crust, and vast deposits of once-molten material hurled outward during the formation of the giant impact basins.
