Are We Reaching Satellite Saturation Point?

Satellites surrounding the earthWe all like our satellite navigation systems and mobile phones, Google maps and BBC World when we find ourselves in hotel rooms, but a report just published by the US National Research Council claims that we are on the brink of clogging up space to the point of no return.

A couple of years ago 2 satellites collided destroying both of them, one had already been decommissioned but the other was a communication carrier that was still in use. Also recently, astronauts had to get in to the emergency escape capsule on the International Space Station as debris passed close by.

There are about 22000 big pieces of debris floating round the Earth and many more smaller but potentially equally damaging pieces, and the problem is the lack of international agreement upon the use of near space. Almost everything from Sputnik onward is still floating about up there. The Chinese military destroyed one of their disused military satellites in an experiment in 2007 but that just created thousands more potentially dangerous pieces. More of a political action than a potential solution.

Now maybe we can live with the odd collision now and again, but a related and really serious problem and the underlying cause, is our reliance on this technology. Scientists talk about potential damage from solar flares and the likes, that might even knock the entire system out for an undefined period of time. This would have catastrophic effects on the world, no Satellite navigation means no aeroplanes, ships navigating by the stars, emergency services having to rush out and buy maps of the city, UPS and their competitors losing their way, and even worse than all this Sainsbury’s not being able to deliver Mrs French’s vegetables on time.

Easy to take lightly but really quite a serious problem.

Dependence is a difficult thing to overcome, but scientists are experimenting with bringing old satellites back to Earth. A sort of Kite is being trialled that once attached to its objective slows it down so that it enters the atmosphere and burns up, but this must be seen against a backdrop of more satellites being launched every month. They are both commercially and militarily extremely important.

Who has the right to govern space though? Competition rules and it is big business.

For a more detailed incite have a look at these postings on the Bassetti Foundation website.

Technology and immigration

I find myself in Boston in the US today, after a long couple of flights. Milan to Dublin wasn’t long but I only had an hour for the connection in Dublin, and in Milan they could not print my boarding cards so I had to go through a sort of check in process again – and it took ages.

First I queued up for 20 minutes to get my boarding card, no problem. Than I had to go through US clearance, new to me, but do what the man says when at the airport I always say. An incredibly long and arduous process of form filling in a hurry, through the body scanner, fingerprints, mug shot, another body scanner without shoes, constant race against time, very stressful (with 2 small children) and finally to the plane 2 minutes before leaving. Oh but it didn’t leave. We had to wait for the other late arrivers to get US clearance, so we waited 45 minutes on a full Airbus for the last few people.

A flexible border?

Something struck me at the time, the security personnel were all American and the stars and stripes were everywhere. Then the strangest thing. We arrived in Boston and we didn’t have to clear customs or show our passports! In fact we came in through the domestic arrivals terminal and the person waiting for us was in the wrong place.

Then it struck me, we had come on a domestic flight over the Atlantic. The US border has moved, it now takes in part of Dublin airport!

The technology was incredible, I had to identify my bags on a photo as they were being loaded onto the plane, and they have all the information they need about me.

But just because the possibility exists and technological advancements mean that the border can move and information can be sent in real time to the rightful authorities does a state (the most powerful state in the world) have the right to use it in this way? And what about the political implications? I suspect that the Tajikistan government would find themselves in difficulty during the negotiation process if they wanted to enforce a similar line.

Rule Britannia, the waves maybe but certainly not the skies!

Prosthetic limb technology and elective amputation

Recently on the BBC World Service I followed a news article about a young man who decided to have his hand amputated in order to have a prosthetic version fitted. His hand had been damaged in a motorbike accident and was not fully functioning, but was however still attached to his arm.

His decision rather took me aback, here was a person choosing to improve the performance of a hand with a replacement. This is fundamentally different to fitting a prosthetic hand to a person that has either lost one or was born without one. The problem seems to be in the quality of prosthetic limbs.

A prosthetic hand

An example of a high technology prosthetic hand

Prosthetic limbs can be operated through the existing muscle system, for example they can be attached to existing muscles in the arm or by using electrical impulses. In this case the muscle use generates an electrical impulse that makes the hand move.

Scientists are currently testing a system that works directly from the brain. Implants register the brain’s impulses and send them directly to the hand. You think about the movement and the hand moves.

There is another advantage too, sensors in the fingers can send signals back to the brain so the user can actually feel the object they are touching.

All of this raises some questions, soon technology will provide us with a fully functioning prosthetic hand that the user controls directly with their brain. It will be hard wearing, reliable and you can touch hot things without burning yourself, it will in fact be better that a human hand.

People might then have elective amputation in order to get one. Who can make legal and ethical decisions about such an intervention? This argument also has implications for sport. South African athlete Oscar Pistorius has recently qualified for the Olympic Games in London and will be competing with 2 prosthetic legs.

Oscar Pistorius - the fastest man on no legs

Nicknamed 'the fastest man on no legs' this is Oscar Pistorius in Greenwich London before next years Olympics

Here we are moving into a discussion about the confines of the human body, but also about enhancement. Maybe he even has an advantage over human legged athletes.

Have a look at Transcendent Man for a futurist view of how robotics and medicine in general might change humanity in the future.
