Too Close To The Sun

Maybe they should have called it Icarus! This story is about Genesis, the space probe sent to collect solar data. It crashed in the desert instead of being "caught" by a plane as was NASA's plan. In other space news, two new planets have been discovered that are not gas giant like Jupiter, but resemble icy, rocky planets like Neptune. As our telescopic prowess increases, our ability to detect Earth-size planets becomes possible:

September 2, 2004:

The race to find distant new “Earths” heated up considerably yesterday with the detection of two of the smallest planets ever detected outside the Solar System. Whereas previous extrasolar planets discovered were almost exclusively gas giants, similar in Jupiter and Saturn and between 100 and 300 times the mass of the Earth, the newly found planets are much smaller – only 15 to 20 Earth masses. This places them in the mass range of Uranus and Neptune, somewhere between the gas giants and the small rocky planets ofthe inner Solar System. “We can’t see the Earth-like planets yet,” summed up Paul Butler of the Department of Terrestrial Magnetism at the Carnegie Institute, who was involved in both discoveries; “but we can see their big brothers”

One of the planets was found by the veteran planet-hunting team led by Butler and Geoff Marcy of U.C. Berkeley, the group responsible for detecting the majority of the 135 or so planets discovered to date beyond our Solar System. The planet orbits the M class red dwarf star Gliese 436, located only 33 light years away, in our own galactic neighborhood. Like many of the known extrasolar planets, Gliese 436’s companion remains very close to its star, completing each revolution in a mere two and a half days at a distance of 4.1 million miles. Most significantly, the planet’s minimum mass is only 21 Earth masses, equal to 1.2 “Neptunes.”
When Jon Stewart heard about this, he said, "Hmm...33 light years - that means it would take us only about 500 years to get there!" I was so disheartened, I said to my wife, "That's under current propulsion systems."

A Valid Path

Last weekend I completed ripping my Alan Parsons CD collection and started listening to it at work off my portable media player. While listening, I figured I might as well google Alan, maybe there would be some interesting historical stuff on the web. As it turns out, Alan Parsons is still kicking and has a new album out! Even better, he's doing electronica now! I'll be receiving it shortly and will do a review. This will be the first record without his long-time bandmates Ian Bairnson, and Stuart Elliott. The new album will take Alan in a new direction and into the world of electronica. Artists appearing on this record include: Nortec Collective, The Crystal Method, Shpongle, PJ Olsson, and Pink Floyd's David Gilmour.

US death toll in Iraq tops 1,000

Senator Kerry calls this a "tragic milestone," and the most catastrophic of the administration's mistakes made so far. Regardless of his mistakenly voting for the war at the time, he's right. For him to turn against the Iraq war is a flip-flop I would be happy with. Hopefully he has an exit strategy, even though he's not telling us about it at the moment. This is why Bush must be defeated in November. I realize the economy is an important issue, but compared to 1000++ dead soldiers? Come on. Not to mention 7,000++ wounded, and the 11,000++ estimated by the Iraq Body Count . This is a slam dunk, as George Tenet would say. Prediction: if Bush is [re]elected, the U.S. will engage in pre-emptive war against Iran and/or North Korea. Is that really what we want?

And What Happens When I Don't Wait Well?

I guess you get anxious ... and we all know what that’s like. But I think that “ yakhal ” (Hebrew) or " elpis " (Greek) does not preclude the possibility of action - whether it’s writing about the situation, or something more (and don't underestimate the power of journaling!) Indeed, you don't think of prophets or apostles as the kind of people to sit around just waiting for something to happen. They act, but their action is tempered by the realization that things don’t look too good at the moment (otherwise why would the issue even be coming up?) So they act and wait at the same time, knowing that the fruits of their action are ultimately dependent on the Lord. And of course the Lord is known to have us do things for a while before any kind of clear result is made known. Like planting, and then watering, and then waiting, for a seed to turn into a plant. Farmers probably understand waiting a lot better than we do. They think in seasons and years, not months or we...
