What Does Saturn Look Like From an Asteroid?

July 14, 2010 Leave a comment

The spacecraft Rosetta is on its way to comet 67P/Churyumov-Gerasimenko. But along the way, they decided to fly it by asteroid Lutetia. On July 10th, Rosetta got to within 3200 km of Lutetia, and the ESA streamed the approach live online.

Now, they have released the photos and they are AWESOME!

This one is my favourite. They managed to catch Saturn in the background when Rosetta was about 36000 km away.

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

June 28, 2010 1 comment

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…

UFOs Over Australia

June 14, 2010 Leave a comment

Well, people thought they were UFOs at least.

The first incident was the Falcon 9 rocket, which was the first test launch of the rocket design by independent space company “Space-X”. The rocket was launched on June 4, 2010, made it into orbit and produced a “lollipop-type spiral” over Australia in the early morning.

Understandably, not many people knew what the lights were, and many UFO reports were made. But the flight path of Falcon 9 matches up perfectly with the time of the sightings.

Sorry folks. No aliens.

Most recently was the re-entry of the Japanese space agency’s craft Hayabusa. The craft ended a 7 year round trip journey to asteroid Ikotawa, and (hopefully!) brought back some asteroid dust for us to study.

The main craft burned up in the atmosphere on June 13, 2010, leaving only the 40 cm wide capsule containing the asteroid sample intact as it landed in the Australian outback.

The re-entry of Hayabusa was captured by an aerial camera mounted on a DC-8 flying over Australia, and produced this stunning video.

Damn Australians get all the good light shows. Maybe I’ll get to see a UFO one day…

Awesome Science: Missions to Asteroids

June 2, 2010 1 comment

A few years ago, everyone was obsessed with asteroids. “Armageddon” smashed at the box-office, despite new-fangled levels of sucking. But sadly the enthusiasm has waned, and the most popular story on earlier today was about Heidi Montag (She’s splitting with Spencer?!? Oh No! How many plastic surgeries will it take to cure this round of heartache?).

So here for your enjoyment is a synopsis of two really cool space missions whose goal it is to study asteroids. These stories I deem more newsworthy than the crap in the headlines.

1) Hayabusa

A product of the Japan Aerospace Exploration Agency, Hayabusa launched in May of 2004. In November of 2005, it landed (yes, it landed!) on asteroid 25143 Itokawa and attempted to collect rock samples. Unfortunately, the metal projectiles which Hayabusa was supposed to fire to dislodge some fragments of the asteroid may have malfunctioned.

Also unfortunate was the loss of MINERVA, a mini-rover which was supposed to be released from Hayabusa to scurry around the asteroid surface. MINERVA was released too high an altitude though, and tumbled out into space.

Even though it may not have collected large fragments of the asteroid, Hayabusa almost surely capture dust and other particles when its bay doors were opened, so the mission should still yield some positive results.

In any case, we will find out on June 13, 2010 when Hayabusa returns to Earth to deliver its cargo.

2) Rosetta

The European Space Agency launched Rosetta also in 2004. Its primary mission is to land (yes, land!) on comet 67P/Churyumov-Gerasimenko, with which it will rendezvous in 2014.

Along the way though, it will do flybys to two asteroids: 2867 Steins, which it already did a flyby in September of 2008, and 21 Lutetia which it will flyby in July of 2010.

Once reaching the comet in 2014, Rosetta will help give us a better picture of what comets are made of and the composition of the solar system before the planets were formed.

Now I know I am a nerd. Its OK, I’ve come to terms with it. But I find it pretty amazing that humans can build a machine, launch it into space, have it LAND on a comet or asteroid, and bring comet/asteroid stuff back to us! In fact, I would be so bold as to say that this is more interesting than the status of Heidi and Spencer. But I guess that’s just me…
