The Abbreviated History of a Scientist (Namely, Myself)

Story

My first word was JET, since we lived near an Air Force base and experienced sonic booms on a regular basis. My fascination with the heavens took off from there. Growing up, my family went camping and backpacking a lot, and one of my clearest memories of that time is looking up at a dark, dark sky and pointing out satellites to each other, those little moving points of light that are sometimes so faint I could only see them in my peripheral vision.

When Worlds Collide

Story

A particularly bright fireball was observed earlier today over a wide area in Russia. Of even greater significance was the very strong sonic boom associated with the passage of the meteor through Earth’s atmosphere.

Flying Low and Slow Over a Lava Flow

Story

This September, Larry Crumpler, a research colleague at the New Mexico Museum of Natural History and Science, and I were able to fly in the back seats of two weight-shifting ultralight aircraft during a two-hour flight over the McCartys lava flow in central New Mexico.

Satisfying Our Curiosity: Mars Science Laboratory and the Quest for the Red Planet

Story

Mars has long held a special fascination for humans—in no small measure because of the possibility that life either presently exists or at some time in the past has existed there. In his classic work Cosmos, Carl Sagan asks an important question: “Why Martians?” Why do Earthlings not similarly obsess over “Saturnarians” or “Plutonians?” As a planet resembling our own, Sagan concludes, Mars “has become a kind of mythic arena onto which we have projected our earthly hopes and fears.” NASA’s Mars Science Laboratory (MSL) Curiosity rover is scheduled to land on the Red Planet in the early morning hours of August 6, 2012 EDT. Thus, “Why Mars?” is a question that we will seek to answer for visitors to the National Air and Space Museum.

Climate Change in the Solar System

Story

We are all familiar with the climate on Earth: the seasons, the range of surface temperatures that are just right for being a water world, the oxygen we breathe, the ozone layer that protects us from UV radiation. In short: habitable. So what other bodies in the Solar System might be (or might have been) habitable, and why aren’t they today? Mars probably comes to mind, and for good reason. Mars has the most similar climate to our own, with water ice caps at the poles, seasonal snow, and dust storms. This is because Mars has a similar axial tilt as the Earth, which creates similar seasonal temperature variations.

Mapping Everything

Story

The universe is about 13.7 billion years old and has expanded since its beginning at the Big Bang. Because distant objects appear to be receding as the universe expands, the light from them is “stretched” out, altering its wavelength to the red part of the electromagnetic spectrum. This “redshift” can be measured for every object in deep space.
