The newest addition to the Time and Navigation gallery is a life-size bronze statue of a dog named Sydney. Sydney now reclines amiably on the deck of the exhibition’s ship, and our youngest visitors are finding him appealing. On a recent morning, one toddler was observed patting the statue’s head and squealing, “Puppy!” Another clambered onto Sydney’s back and went for an imaginary ride.
The Viking program represents a major effort by the United States to explore Mars, with the particular goal of performing experiments on Martian soil to look for possible evidence of life. Four individual spacecraft were sent to Mars as part of the Viking project, two orbiters and two landers, launched as identical orbiter/lander pairs.
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.
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.
The recent 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.
In July, I joined a team from Johnson Space Center and elsewhere in investigating the geology of Apollo Valley with rover-deployed scientific instruments. Apollo Valley is a former 1960s Apollo-era astronaut training site at 3,505 meters (11,500 feet) on Mauna Kea, Hawaii. The project was funded by NASA's Moon and Mars Analog Mission Activities Program, which funds projects that simulate scientific, robotic, and human aspects of exploring the Moon and Mars, with the goal of designing the most effective, efficient, and well-integrated future missions.
Astronomy enthusiasts around the world are gearing up for Tuesday’s celestial show: the transit of Venus across the face of the Sun. The small black dot of Venus, silhouetted against the bright Sun, will be visible with safe solar telescopes and, to those with especially good vision, with the naked eye when protected by eclipse glasses.
