ESA Declares Flagship Envisat Observing Satellite Lost 39
An anonymous reader writes with news that the European Space Agency has lost contact with its Envisat environmental satellite mere weeks after celebrating a full decade in orbit. Engineers have spent the last month trying to re-establish contact, and will continue to do so for another two months. "With ten sophisticated sensors, Envisat has observed and monitored Earth’s land, atmosphere, oceans and ice caps during its ten-year lifetime, delivering over a thousand terabytes of data. An estimated 2500 scientific publications so far have been based on this information, furthering our knowledge of the planet." The ESA was hoping Envisat would stay operational for another two years, until Sentinel satellites from the Global Monitoring for Environment and Security initiative became operational.

If we had a Star Tram running it would be trivial to fix. Seriously, $2 billion and poof! Gone, no way to retrieve or repair it. This really underlines the ridiculous state of our global space industry.

Maybe you're just trying to be funny. Envisat did much to establish the facts and mechanisms of climate change. There's no conspiracy: it grew old and died.

Given that a Shuttle launch only costs around $150m* USD, I suspect you're way off base. Doubly so since it cost 2.5 *billion* dollars to develop and launch in the first place. Now, admittedly you're not going to pay the full development costs the second time around, but you're still looking at probably 3-500 million plus for the new bird and nearly 200 million for the launch

Have any sources? I do. [nasa.gov]

That's the cost including the share of the fixed annual cost - I.E., an accounting fiction, not the actual amount that would be in the budget. As with any source, you have to be aware of the accuracy and assumptions behind it.
See: http://www.faqs.org/faqs/space/controversy/ [faqs.org] for more information, or google about for "cost to add a shuttle flight to the manifest".
Re: (Score:2)
The shuttle couldn't reach its orbit, and if it could, the satellite was not designed to be worked on in orbit (unlike Hubble), and even if neither of those things were true, nobody would think it a good idea to spend around a billion dollars to try and fix a satellite 5 years past its design life span, with no idea what's wrong with it. Satellites die. Move on.

Where it comes to leaded PCB assemblies, you're wholly and saldy misinformed [sigcon.com]. Non-leaded PCB assemblies have bigger environmental impact due to a confluence of reasons. Any of those reasons by itself is perhaps a minor thing, but when taken together they are quite significant.

Remember, this is a European satellite, they're the ones really pushing ROHS. Many US Companies have adopted it, for various reasons including but not limited to making it easier to do business with Europe.
My particular reference was to NASA. Sometimes, according to testing facility that was established to make sure vendors weren't ripping us off like they did when the door fell off a shuttle, when they check solder on boards ordered from Europe specifying lead solder only with the aerospace waiver, they
