Mars Water and Mars Movie

Yes, this is a geek post; deal with it! One of the major results the various Mars orbiters and rovers have been trying to work out is whether or not the red planet has ever harbored life, and one of the preconditions of life is a water supply. At least our kind of carbon based life, and there are good reasons why two planets in the same solar system would bear the same flavor of life. The most obvious two are:

1) Our planets condensed out of the same orbital dust cloud around our condensing star, and are therefore made from the same ratio of elements at the same stellar evolution stage, and

2) High speed impacts on either planet by rocks with enough kinetic energy to blast objects beyond escape velocity will tend to include any organic building blocks. Some percentage of those ejecta will end up raining down on the other planet, thereby sharing enzymes, RNA, DNA, and other life building structures between bio-zones.

With that as a given, it is exciting to find out they now have the evidence that Mars had water, enough to completely reshape the planet and generate clay deposits, as recently as 4 billion years ago. Since life on this planet started evolving 5 billion years ago, we had a clear billion years to cross-pollinate.

But there is one more detail that gave me the biggest grin of all about this; Did you notice that in each article the scientist reporting the Mars results was named after the ERB character John Carter of Mars? Is this going to impact on the movie? I am ready for that film!

Halley’s Comet pieces to hit Earth

Tiny pieces of Halley’s Comet will be hitting Earth for the next week in the form of the Orionids Meteor Shower. The tail of Halley’s Comet is made of dust and small pieces of ice and rock that has broken off the comet itself, and now follows an independent orbit around the Sun. That orbit crosses the Earths twice each year, with the Orionids being the second pass. The event started last night and will continue for a week or so, with the peak display coming Wednesday night. Since we will be within a few days of a new moon, viewing should be good as long as you can get away from city lights. This is one of a series of meteor showers you can see each year, and the International Year Of Astronomy viewing tips will get you ready. Lest anyone was concerned, Halley’s Comet itself, the main ball of ice and rock, will not be impacting the Earth any time in the next thousand years or so; just the tiny pieces that broke off.

Bombing the Moon: LCROSS

Four months after the launch, tomorrow LCROSS will smash into the moon. Specifically, it will crash into a Dark Crater at the moon’s south pole, in an effort to find water on the moon. Locating a local source of water is critical for extended manned missions and habitation there. Details about the chances to see these events yourself can be found here, including a link to NASA TV Online, where you can watch the event live beginning at 3:15AM PDT, 6:15AM EDT.

POP Stars

The National Air and Space Museum unveiled POP today: the Public Observatory Project. Another celebration of the International Year of Astronomy, the historic 16-inch telescope set up in the observatory will be available for daytime use by the public. Craters on the moon, phases of the planets, and sunspots (with appropriate filtering and/or projection optics to protect Mark 1 Eyeballs from being burned out) are just some of the things the public can see there. If you can’t make it to the Smithsonian, you might want to visit Experience the Planets instead, and see the solar system through the eyes of artists. Or perhaps you would like to read a little about NASA’s Replicator, not quite ready for an order of Earl Grey, hot, but it can make parts for aircraft and spaceships at nearly the molecular level.

Musical Questions about Rockets

I can’t help it, sometimes I just wonder about things. One of my current questions is: Will Soar Thoat be doing some of the music for the new John Carter of Mars production? I know, the band’s name is a serious Martian pun, and the Civil War veteran did not arrive on Mars by way of Rocketship, but I still wonder. Continuing on the musical front, there were two versions of the almost-question (they each answered it themselves, so it doesn’t count as actual questions) If I Had A Rocket Launcher. One is a Hi-Q rock construction from musical genius and politically aware Bruce Cockburn, the other a fun little construct from Halo gamers creating their own Machinima. The question this time is, which music video do you prefer? Here are your samples to choose between…
