I come to you from Planet Science, cooking up a tasty stew of words, moving pictures and thoughts aimed at introducing non-science folks to the Universe and all of it's wonders.

Comet 67P and Rosetta: a tribute

Comet 67P Churyumov–Gerasimenko, or just plain 67P has been a bit of a superstar ever since the European Space Agency’s Rosetta Probe fell into orbit around it in August, 2014. 

On September 30, the probe will end two years of solid science with a programmed death dive into the head of the comet. This isn’t quite as dramatic as it sounds; 67P’s gravity is several hundred thousand times less than that of Earth. Rosetta will gently tumble at breakneck speeds of 90cm a second. In fact, on hitting 67P’s gnarly terrain Rosetta may bounce off, careening back into space for future space travellers to find and ponder over.

67P has seen it’s share of drama. On contact with the comet. Rosetta will join the Philae Lander, which unfortunately was given up for dead two days after landing. This was due to an awkward landing on the comet’s uneven surface which saw the lander wedged in a sunless crevasse. 

But Rosetta has actually been quite sucessful; both in terms of technical achievement and in new discoveries. In situ discovery of complex organic molecules further cements the possibility that comets may seed the universe with the precursors of life.

67P is believed to have originated in the Kuiper Belt, an ancient cloud of dust and matter hailing from the primordial Solar System. The significance of organic compounds on 67P (or any similar body for that matter is this: their presence may indicate that life precursors may have existed in the primordial cloud from which the Solar System formed.

This is exciting for astrobiologists no doubt, and we look forward to more sciencey goodness. In the context of near earth like planets being discovered all the time studying these findings may be important to humanity’s future among the stars. It’s been a fun ride, Rosetta, and every image, every discovery has shone a little more light on our universe.


Looking back

University was at once an excercise in hair tearing frustration and bliss. Was it worth it?

Graduation day, 2009.

In 2005, after a good sixteen or seventeen years in the workforce I decided that I’d had enough of (extremely) low paying jobs in the hospitality industry and I wanted to go to university. 

In a way I have C.S.I. to thank for this. The Las Vegas series of course. Gil Grissom was the man. After becoming hooked on this show I thought that forensics might make for an interesting career. 

I have no doubt in my mind that forensic science would be fascinating.  Not quite as action packed as Gil’s exploits perhaps- but still pretty interesting. Anyway, suffice to say, forensics only got me as far as application. The university I was applying for didn’t have much in the way of forensics courses.

So, I went for science. Since I could remember I’d always wanted to be a palaeontologist. I still own the very first dinosaur books I ever had. One was this big picture book with these really cool pictures in it.

The other was this chunky encyclopedia type thing I unofficially inherited from one of my uncles. I remember many hours lost in the prehistoric vistas depicted in those pages, as well as the diagrams of bones and skeletons. 

Anyway. Science. Dad was obsessed with knowledge and learning. While other kids were outside with their dads kicking footies Dad and I were having lengthy discussions about just about everything from archaeology to natural history to just about anything. Even religion. Dad’s mind never stopped moving for one second.

Dad. My first real teacher.

God I miss you dad. 
University was at once huge and scary and a massive leap into a great unknown. I majored in Biology and Earth sciences. Palaeontology is found at the intersect between these two vast areas and I still had dreams of ending up on a hillside somewhere pulling some new creature into the light.

Over time I gravitated towards microbiology and molecular biology as areas of interest. Biology in general. I could never settle on mathematics or chemistry and I didn’t even give physics a glance. The living world was it for me. 

The challenge of university was it’s own reward. I dove into study, and while I didn’t set the world on fire, I did pretty well. My Honours year was hard work. I was working three part time jobs and dealing with an extra complex family life, while at the same time squeezing in an Honours project. 

Was all this worth it? No long term career in the sciences. No career in education. What did I get out of it?

I’ll have to think about it.

Schröedinger’s Memory

So. This is the first official foray by Ben’s Lab into “proper” blogdom. 

Welcome to you, Dear Reader. 

I’m sitting on a plane right now, waiting for it to take off. The engines are rumbling gently, somewhere in the innards of this metal beast, and I wait; with a little trepidation, for the damn thing to take off and hit the skies. 

Now we’re moving.  

It’s a slightly unnerving feeling. I’m not going to lie.

Flight mode. The phone I’m typing this blog post on has a little feature whereby the phone’s ability to send and receive radio/microwave signals is cut off.  This is apparently so it doesn’t accidentally interfere with the plane’s navigation systems.  
I know the nuts and bolts of the idea, and so am not going to dwell on it here. 
What does interest me though, is the concept itself. Flight mode.  
The plane just left the ground. I hate that part. 
Flight mode.  A period for around two hours (that’s for this flight) when I am utterly alone in the world. Think about it. We are so connected to everyone else via our little electronic gizmos that it’s akin to modern excommunication when we suddenly aren’t. 
It’s as though in that couple of hours we suddenly don’t exist. Of course we do, I realise that. The same collection of atoms and interacting systems that got up this morning is still here, furiously tapping away at this screen. 
But the signal connecting me to the world is gone.  I’ve been flicked off the grid for a little while. 

I’m flying through the sky, and the world doesn’t know quite where I am. Only others aboard this plane do. It’s a weird feeling. 
Schröedinger’s cat comes to mind. I think it’s on this plane with me somewhere. 

R.I.P. Jack. A cat whose connecting signal didn’t cut off for 19.5 years. He’s part of the seen/unseen now

I’m a person who likes to think about these things: and their place in the great scheme of things.
