Submission + - NASA's Comet Hunter, Stardust, Retires (ibtimes.com)

RedEaredSlider writes: A few weeks after NASA officially sent the space shuttle Discovery into retirement, it is saying goodbye to another spacecraft: Stardust.

The Stardust spacecraft was NASA's foremost comet hunter during its 12-year career. On Thursday of this week, it sent its last transmission to Earth, immediately after one final rocket burn. The team behind Stardust said the spacecraft was running on fumes and wanted to see how much it had left. It was 312 million kilometers (194 million miles) away in space when it sent that final transmission.

(...) people are far too quick to call for search and rescue.(...)

I could not disagree more.

It takes a long time for SAR ressources to get to your location when you are stranded somewhere, sometimes up to several hours. It's not like when you're in the city and you just dial 911, and you have an ambulance, cops or firefighters at your doorstep in minutes. So when you decide that you've been stranded long enough, that your boat fire is out of control just now, that your plane is going to dive nose first, or that you've been lost so long that you can't remember... well, guess what: you'll have to wait a bit longer, buddy ! .... and good luck btw.

I have had many cases at my SAR-related job of people calling in, not wanting to disturb, a bit shy, and hesitant, reluctant to being rescued.... where it'd be SO f* much easier for us to go save your ass, and done - and done. We get a thrill when we get this chopper - or boat - or volunteer searchers call list - going anyway.

I plead for anyone who ever needs SAR service not to hesitate a minute. Because when you decide that you REALLY REALLY need NOW a rescue... it might be too late.

Unless, you think your life, or the safety of whoever is on a trip with you - family & friend - is not worth a phone call, or that your ego is more important.

You are wrong. All of those ridiculous units you use in the states haven't been used anywhere else for years. The metric system is the only one, therefore nm is nanometers. You are a stupid person for suggest otherwise.

I don't know why I'm replying to this as you seem a bit reluctant in other's opinion, but I'll try anyway.

The Nautical Mile is recognized internationally and used primarily in navigation, ie. marine & air (ISS is air, right?) The International Civil Aviation Association uses nm as its symbol ( Wikipedia page or the initial reference )

And should it matter - which I don't think it does - I am not a US citizen. I am working in the marine field, and the nm is the de-facto unit here.
