Ion drives were also user in the European Artemis spacecraft which is geostationary. Too bad the Arian e launcher had a problem reducing a lot the "life expectancy" of the satelite who had to use most of its fuel to reach the geostationary slot.

The ion drive is very good for long distance journeys. There is a limited amount of speed you can achive with classical propelents. The speed you can accelarate with ion drive is far greater. Best example Deep Space One.
The problem will not be contamination of space, the prblem will be if the Ariane goes kaboom again on the launchpad. Then you risk plutonium contamination allthough the quantites will be minimal. At leat comapred with Chernobal.:)

Unfortunatelly some postal workers were infected and some even died + caused wide spread panic. Also some postal offices were out of service and doing cleanup for months. I guess it was a DOS on the society as a whole and on postal service in particular even though the target was different.
I thought true scientific achievements come out only due to lack of censorship even if we are talking about self censorship. There is no good science or bad science, it is only science. Extreme cases of censorship of science we saw in the midlle ages with the inquisition when some clerics decided what is good science and what is bad science. We all know what that lead to. I know we are talking here about self censorship, but isn't that another form of inqusition? Or more acuratelly said a form of self iquisition. Look for example at the Openheimer case. Indeed it was tragic that Hiroshima and Nagasaki were destroyed killing tens of thousends of inocent people, but more were killed than in the both cases toghether with thw Tokyo classical raid. Also we lived throughout the cold war with the fear of nuclear holochaust, which thank god never happend, but nuclear power did happened. Therefore self censorship will only bring a new form of dark ages.
Yep. Plus using CDMA (DSSS or FHSS) you never know how much throughput you'll get at a given time even taking in account the overhead. So that Mbps thing is useless.
The gain deppends on the frequency. Low gain for low frequencies and high gain for high frequencies. Also high bandwidth with BPSK modulation might work better than low bandwidth 256QAM modulation.
I know what you mean m8. I used to work in government funded environment but due to lack of funds I am right know in the corporate world and sudenly Dilbert.com transformed into reality.
I would rather live live in a society where most source is open and programers are paid from governmental research funds and when they are thrown out of a project they will have to work in a corporte environment and code in visual basic untill they get back on track.
I allways found that kind of alliances creepy. This kind of thing never promotes value. The end of all this will be that all EA games will work verry bad with ATI boards and non EA games will be less competitive on Nvidia. Finally the end user will end up screwed.
Even old 802.11 standard can reach 50km. There is no limitation of distance in the actual protocol. With high gain antenna, line of sight and enough power you can shoot much more. Actually there was a trial in Sweden using metorolagical baloons and they did more than 200km with 802.11b. The main concern is LOS blocking due to curvature of the Earth. If you want to shoot 60km and have one antenna at ground level, you need to have the other one at least 200m high. And this will aplly to 802.16 too.

At least if the launch fails they will have a nuclear test.

Your linux server is in denial. ;)
Another bonanza for lawyers.
Unix claimed ownership of the Novel 5.0
NFS still needs some cleaning up.
Where I live the office is still returning it, but unfortunatelly not to many spamers arround.

You can allways put in the envelope without a stamp and him as expeditor.
yep. And I guess the Unabomber was the physical incarnation of the "mail bomb".
Wasn't the last DOS attack through postal service using anthrax?

Depends verry nuch on the environment. You'll get 60% in the countryside while 20% in crouded spectrum metropolitan area might be a good asumption.

I'll give you 5$ for it. :) Still you can build a firewall out of it so all is not lost.

No! This is the coalition.

Does this mean that will take 2k years to wipe out LA? How unfortunate.
