LCROSS preliminary results
Hey remember when we bombed the moon? Here’s an interesting article about some preliminary results from LCROSS. I was especially surprised when they said that there may be mercury at the impact site. They say they’re seeing spectral lines that could be produced by iron, magnesium or mercury, but then the article goes on as if mercury is the likeliest candidate! I’m skeptical. Fe and Mg are common in lunar …

How Habitable is the Earth?
Charlie Stross has an interesting post on his blog that asks the question “How habitable is the Earth?” He goes on to conclude, through a great discussion of the evolution of our planet, that the fraction of time that the earth has been habitable to humans is a tiny sliver of the time the Earth has been around, and that furthermore, much of the earth is not habitable for humans …

So go vote for my post if you haven’t done so yet today! Don’t worry if you don’t see a number in the grey voting widget box.

NaNoWriMo 2009
Well, it’s that time of year again. Against my better judgement, I have decided to participate in National Novel Writing Month (NaNoWriMo) again this year. For those unfamiliar with NaNo, the idea is to write a >50,000 word novel in the month of November. It’s a great way to get over the inner editor and just write, and I’ve been putzing around with this year’s story idea since earlier this …

New Photos of Stuff on Other Worlds
I always make the mistake when on vacation of taking too many pictures of scenery and not enough pictures of people. Years down the road, the most interesting photos are not landscapes, but the ones that we can look at and say “I remember when we did that!”. And that’s why I think it’s great that we now have cameras around the Moon and Mars that can do the same. …

Ares-1X Test Launch Successful!
In case you missed it, this morning NASA launched the Ares-1X test rocket from Cape Canaveral. It was originally supposed to launch yesterday morning, but was delayed due to: a stuck cable, a boat that got within the danger zone where the rocket was expected to splashdown, and my new favorite vocabulary word “triboelectrification”. Triboelectrification is the build-up of charge due to friction, and there was apparently some concern that …

NASA Human Spaceflight Review Final Report
Today, the “Augustine commission”, a group of aerospace and space exploration leaders tasked by president Obama to review NASA’s human spaceflight efforts, released their final report. It is available here, and I encourage you to read it. The set of recommendations in the report will form the foundation upon which the future of space exploration is built. I have not read the whole thing yet, but here is the concluding …

Dozens of new Extrasolar Planets
The universe just got a little more crowded! Space.com is reporting that Astronomers using the European Souther Observatory’s 3.6m telescope in Chile have discovered 32 new extrasolar planets. The smallest of these could be ~5 earth masses, while the largest would dwarf Jupiter! Check out the full story here.
