The Onion Hits the Nail on the Head

February 3, 2011 Leave a comment

Phil Plait posted this link on his blog, and I had to share it as well.

It so well articulates the current political climate in the United States that, despite the fact that an asteroid is not headed for Earth, it should get circulated like mainstream news stories.

The Onion: you are awesome!

“Republicans Vote To Repeal Obama-Backed Bill That Would Destroy Asteroid Headed For Earth”

My favourite quote from the article:

In an effort to counter Republicans’ claims, Democrats have asserted that the long-term benefits of preventing the United States from being incinerated by an explosion several billion times more powerful than the Hiroshima bomb would far outweigh the initial monetary outlay.

 

We Got Asteroid Dust!

Phew. Gotta clean the dust off my computer. Why does moving have to take up so much time?

Well while I was lugging heavy boxes, there was stuff still going on in the world of science.

Perhaps the thing that got me most excited was that the spacecraft Hayabusa, which I have written about before, has succeeded in its mission!

Japanese researchers announced that the craft has acquired fragments of asteroid dust and returned them safely to Earth.

The craft was launched seven years ago, and in 2005 it landed on asteroid Itokawa. Despite some engine trouble, and the fact that the ball bearing it was supposed to shoot into the asteroid’s surface failed to fire, the craft still managed to collect some fragments of space dust.

Hayabusa returned to Earth in June of 2010, and we have been waiting anxiously for months to find out if the craft had actually gotten some asteroid bits back for us to study.

How do we know these particles are definitely from the asteroid? The official announcement states:

The mineral phases among the collected 1500 particles, their relative abundance ratios and their elemental compositions agree with a class of primitive meteorite, and they do NOT correspond to any rock type on the surface of the Earth.

This absolutely blows my mind! These guys were able to launch a spacecraft, land it on an asteroid, take off from the asteroid and return to Earth with pieces of it!

I think we all need to take a moment and think what it would be like to be working on this project from the start. Seven long years it took, with obstacles almost every step of the way, and now they find out that it was totally worth it. Kudos these researchers, who are no doubt still out partying in celebration.

“Damned Fools Won’t Pay 10 Minutes Attention to Science and Technology…”

So if you’ve read this blog, you know I am more than displeased at how Science is reported in the media, and how little credit is given to the work of scientists.

People find Science boring. And while I do sympathize sometimes, at other times I get pretty frustrated.

Perhaps not surprisingly, I’m a big Sci-Fi/Fantasy geek. I just started reading “Lucifer’s Hammer” by Larry Niven and Jerry Pournelle. Its about a comet which strikes Earth and civilization needs to rebuild. Pretty cool.

There is one part near the start of the story where a news reporter is speaking with an Astronomer. It sums up my feelings really well, so I thought I would share it with all of you:

“Yet the damned fools won’t pay ten minutes’ attention a day to science and technology. How many people know what they’re doing?

Where do these carpets come from? The clothes you’re wearing? What do carburetors do? Where do sesame seeds come from?

Do you know? Does one voter out of thirty? They won’t spend ten minutes a day thinking about the technology that keeps them alive. No wonder the research budget has been cut to nothing. We’ll pay for that. One day we’ll need something that could have been developed years before but wasn’t -“

And get ready for my next post, its gonna quite a rant…

Asteroid Hits Jupiter!

Jupiter Impact Scar is Going, Going, Gone

Last year in July, an asteroid struck Jupiter, leaving behind this dark black scar on the planet’s surface.

As luck would have it, an amateur astronomer named Anthony Wesley happened to be recording the impact as it happened! He has posted this video:

This is some freaking cool stuff! You can read more at the Hubble Telescope’s Website.
