Twenty years ago this summer, in July 1994, a comet known as Shoemaker-Levy 9 smashed into Jupiter. That was a big deal with scientists because they got to see just how big of a deal getting hit by a comet or asteroid was. I suppose if the dinosaurs were still around, they could have just asked them.
Last week, word came out that a meteorite had recently smashed into Mars. They’re not sure just when it hit. They think some time between July 2010 and May 2012. They don’t really know because they weren’t watching for it. NASA has been busy with Muslim outreach, and other scientists are too busy trying to prove that cold weather is a result of Global Warming.
Oh, and, in case you forgot about it, the Moon was hit last March.
So, what do these events, spanning 20 years, have in common?
Well, let’s look at them.
In 1994, Shoemaker-Levy 9 missed Earth by 400 million miles.
In 2010 or so, an asteroid missed Earth by 40 million miles.
In 2013, an asteroid missed Earth by a quarter-million miles.
Those of us that have decided the best thing would be to rooting for an asteroid strike? Take heart. The aim is getting better.
