Farewell Dive

Cassini Bids Bye Bye With Last
Jump Into the Rings of Saturn

The spacecraft that’s been orbiting Saturn for the past 13 years, is executing its final dive today. It’ll be a grand finale, fireworks and all, as it’ll crash while taking the last of thousands of pictures and videos it already took from the ringed giant.
It was a risky triumph for NASA, for the $3.4 billion, plutonium-powered probe swung up close by us, in 1999, to use Earth’s gravity to shoot up towards Saturn. A mishap could’ve been disastrous, but it was worth: we’ve learned so much with the little probe that will die today.
These expensive and far-reaching missions always prompt questions as to their validity. It’s no different with Cassini. Many doubted its science, and to some politicians its cost-to-dividend ratio could never be compared to, say, another monstrous taxpayer-funded sports arena.
Since it’s hard to quantify the exact impact Cassini‘s will have on our knowledge – apart from, well, so much more than we knew before -, projects like these may be on their way out. While it traveled to Saturn, nanotechnology, for instance, experienced a quantum leap.
Advances in computer science and robotics, as well as the entry of private enthusiasts in the field of space exploration, may assign a different role to organizations such as NASA, and the European and Italian space agencies, that collaborated to make the Cassini project an astounding success.

A TRANSCENDENTAL STEP IN SPACE
For, however be that as it may, the orbiter, and its hitch-hiker, the Huygens lander, dropped on Titan in 2005, represent a staggering milestone. Its secrets will still challenge us long after everyone alive now is gone. That, by the way, is the only form of immortality that makes sense.
It’s the part when space as a metaphor to the human adventure on this planet resounds the most transcendental. That’s how Italian Giovanni Domenico Cassini, and Dutch Christiaan Huygens, both mathematicians, remain alive and even more relevant today than during their XII century existences.
The Cassini journey has also an added benefit: allowing mankind to witness a complete cycle, which started (more)

The Plastic Oh, No, Band, Colltalers

‘I just want to say one word to you. Just one word… Are you listening? Plastics.’ That was the career advice offered to Benjamin Braddock, in the 1967 movie The Graduate. If the word was just a joke then, almost 50 years later, it now defines our way of life and may point to our demise.
Its presence permeates almost everything considered essential to our living in this planet, plastic may also choke to death its lifeline, the oceans. Everyday, millions of discarded pieces of it reach the world’s waterways and join what’s an already incalculable amount of floating garbage.
In fact, in this past half century, we’ve seen how insidious plastic clogging the world oceans has become: it has been found everywhere, from vast extensions, forming giant invisible islands of flotsam, to deep under the Arctic seas, and out of dead seabirds’ bursted open stomachs full of it.
As part of our daily life, it’s also all over: in the computer where this post is being composed to cellphones, medicine bottles, to product packaging, food containers, to throwaway utensils. It’s almost discouraging to realize how hard it’d be for us do dig ourselves out of this lifestyle hole.
But perhaps not all is lost. Two of the more ominous of its uses may represent both a way out and a method to wean ourselves from such pervasive product: plastic bags and bottles. They both encapsulate extremes of our societal behavior and offer interesting metaphors to our way of living.
Take bags, for instance, banned this past week in California, which may be one of the most important steps taken against plastic pollution since recycling rules have been instituted in the U.S. A positive sign, indeed, that should ignite a chain reaction and lead to a nationwide ban.
Created solely out of convenience, these bags are utterly replaceable, and yet, have a level of adherence in all walks of life that would baffle social scientists searching for common habits shared by all classes. It’s, however, one of the most environment-damaging habits we could possibly partake.
So a ban, as it’s being pursued in New York and other states, and following some European countries, would represent a big step towards controlling ocean pollution, where they inevitably wind up, after decades in landfills. Would a ban also instill a reflexion on our shopping obsessions? Nah.
The other ominous use of polymers is even more ridden with the contradictions of our very own highfalutin approach to a natural lifestyle: bottles. Drinking bottled water became one the most terrible by-products of the ‘living healthy’ movement, one that added millions of tons of plastic to our already Continue reading
