Yes, the sky is falling. The asteroid impact that took place in Chelyabinsk, Russia, on February 15, 2013, has jump-started an international conversation about planetary protection and whether or not there is a really big asteroid/meteor/comet out there with our name on it. There is, we just haven’t found it yet. Miniscule objects enter the atmosphere all the time; occasionally larger objects come down—the Tunguska (1908) and Chelyabinsk (2013) events are prime examples of this—and once in a very great while a mass extinction impact takes place as in the Cretaceous–Paleogene extinction event of 66-65 million years ago that wiped out the dinosaurs.

The news that “Vulcan” topped the poll results taken by the SETI (Search for Extraterrestrial Intelligence) Institute in Mountain View, California as a possible name for one of the two tiny moons newly discovered to be orbiting Pluto has gotten quite a bit of press this week. In 2012, Mark Showalter of SETI, working with scientists on the New Horizons mission sending a probe to Pluto, found a tiny fifth moon orbiting the icy world.

Two years ago today, the space shuttle Discovery was launched for the last time.  My friend Nicole Gugliucci scored a quartet of tickets for the launch and shared them with me, along with our friends and classmates Joleen Carlberg and Gail Zasowski.  Facing an overwhelming load of graduate school work, we decided that a road trip from Virginia to Florida was exactly what we needed.

In a recent post, Tom Paone described the plans of William Powell, a resident of Mobile, Alabama, for a Confederate helicopter. In fact, Powell’s scheme was only the tip of the iceberg. In researching a scholarly paper on Civil War Planes, I have catalogued a score of plans for powered flying machines developed on both sides of the battle lines. Perhaps the most interesting of these was the work of Colonel Edward Wellman Serrell , a professional engineer serving with the Union Army of the James in 1864. Inspired by the well-known hand-held helicopter toy, Serrell had begun studying aeronautics several years before the War.

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.

The seventy-fifth anniversary of the disappearance of Amelia Earhart and her navigator, Fred Noonan, stirred up considerable media attention – particularly in light of another expedition to the South Pacific in the hopes of solving the mystery. While the fate of Earhart has enthralled the public since 1937, the story of how Earhart figures into the larger history of air navigation and long-distance flying is often overlooked.

My coworkers and I are fortunate: every day, we get to touch pieces of history that few others ever lay hands on and seldom see. Why are we so privileged? We are helping to move some of the National Air and Space Museum’s collections from their previous storage site to new facilities at the Steven F. Udvar-Hazy Center in Chantilly, Virginia.

On January 15, 1967, the NFL champion Green Bay Packers played the AFL champion Kansas City Chiefs in what would later be known as Super Bowl I.  Sixty years earlier, American football looked much different.  Helmets resembled aviator caps.  Forward passes had been legal for less than a year.

NASA staffers and leaders had a celebration planned on February 1, 2003 for the return of Columbia and its crew after the successful completion of STS-107.

As my colleague Dr. Tom Crouch referenced in a previous post, our nation is currently in the midst of commemorating the 150th Anniversary of the American Civil War (or sesquicentennial for you Latin fans).
