We recently posted a blog entry celebrating the anniversary of the Apollo 11 landing on the Moon. Now, just a couple weeks later, we are preparing for another first: the European Space Agency’s attempt to orbit and then land on a comet. The Rosetta spacecraft was launched in 2004 with the ultimate goal of orbiting and landing on comet 67P/Churyumov–Gerasimenko. Since the launch, Rosetta has already flown by asteroid Steins, in 2008, and asteroid 21 Lutetia, in 2010.

NASA and the European Space Agency (ESA) have a long history of sending probes to other solar system bodies that then orbit those bodies. The bodies have usually been nice, well-behaved, and spherical, making orbital calculations a fairly standard thing. But, as Rosetta recently started to approach comet 67P, we began to get our first views of this alien world. And it is far from spherical. More »

Although I was born several years after the first Apollo Moon landing, the excitement surrounding the Apollo Moon landings and the space exploration enthusiasm it fostered drastically affected my childhood and shaped the direction my later life would follow. The space race, arguably peaking with the Apollo Moon landings, generated a funding explosion for science education that allowed many planetariums to be built and a phase of education encouragement that affected many of my generation. If we could land on the Moon, imagine what else we might achieve if we worked hard enough.

On July 20, we celebrate the 45th anniversary of the Apollo 11 Moon landing. This landing began a sequence of Moon landings that ended with Apollo 17. We can leverage Wolfram|Alpha and the recently released Mathematica 10 to help us celebrate and continue exploring (data, in this case). The available data includes dates, crew information, and landing coordinates.

Let’s explore the crew information first. As with many famous people, Wolfram|Alpha gives a fair amount of information like birth dates and locations, pictures, time lines, height information, and familial information. More »

“At breakfast time I was sitting by the house at Vanavara Trading Post, facing north…. I suddenly saw that directly to the north, over Onkoul’s Tunguska Road, the sky split in two and fire appeared high and wide over the forest. The split in the sky grew larger, and the entire northern side was covered with fire. At that moment I became so hot that I couldn’t bear it, as if my shirt was on fire; from the northern side, where the fire was, came strong heat. More »

I just got a flat tire and I need to replace it with a new one. What size tire do I need to get? This can be a tricky question, and many of us would just take our cars into a dealership or repair shop and let them deal with it. But it’s not as hard as you might think, and now Wolfram|Alpha provides tools to help you understand tire sizes. More »

So, you forgot your anniversary was coming up, and now you have to decide what you’re going to get your loved one. Wolfram|Alpha can now help point you in the right direction. The stereotypical anniversary gift for a man to give his wife is often thought to be jewelry, but you would be surprised to know that many traditional and modern wedding gifts have nothing to do with jewelry.
