Black Hole Starships?

Do you ever get tired of science fiction stories using black holes to solve every imaginable problem? (I’m looking at you, new Star Trek.) Well, if so, you should not go take a look at my inaugural article for Universe Today, in which I report on a couple of physicists who calculated that a future civilization might be able to create black holes and then use them as powerplants to …

Review: Earthlight

What happens when humans expand to the planets, but then the planets try to assert their independence? It’s a common science fiction storyline, and the central focus of Earthlight. Earthlight is one of Arthur C Clarke’s earlier novels, originating as a short story in 1941 and published as a novel in 1955. It is set at an astronomical observatory on the moon. There is war brewing between Earth and the …

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 …

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 …

Dueling Mars Movies

Last week and this week, Dwayne day posted two very nice reviews of the dueling Mars movies of 2000, a.k.a. Mission to Mars and Red Planet. Now, I know, neither was the greatest movie, but Dwayne’s reviews do a nice job of discussing what was done well in addition to what was done…less well. Take a look, and feel free to discuss these cinematic masterpieces in the comments! And in …

Welcome to Mars! … I mean, Syndey

Last week a dust storm swept its way from the Australian outback and blanketed Sydney with orange dust. The dust storm was pretty large for Earth: 500km x 1000 km, and unusual in that it managed to reach Sydney instead of petering out in the outback. The Big Picture has a great series of photos of the storm, many of which look remarkably martian (if you ignore the water and …
