Gives current location of International Space Station
 
What problem does your Instant Answer solve (Why is it better than organic links)?
Nothing really. Just a fun instant answer.

What is the data source for your Instant Answer? (Provide a link if possible)
http://open-notify.org/Open-Notify-API/ISS-Location-Now/

Why did you choose this data source?
It provides JSON response and data is directly scraped from NASA website

Are there any other alternative (better) data sources?
No. Present data source does the job fine

Space hobbyist, students, etc.

Yes, this one - https://duck.co/ideas/idea/4588/current-location-for-international-space-location

Which existing Instant Answers will this one supersede/overlap with?
None that I know of.

Are you having any problems? Do you need our help with anything?
Yes, API source suggests it should polled once every 5 second and result should be cached. I was unsure whether 'spice proxy_cache_valid => "200 304 1d";' would work for seconds too, so I did not include it.

What are the terms of use for the API? Will DuckDuckGo need specific authorization (e.g. an API key)? Are there any costs associated with API usage?
No, API key is not required and there are no costs for API usage.
