GALEX data license[edit]

I'm not quite sure if data 'released to the public' (according to their web page) means PD. Can someone clarify? --Ayacop (talk) 13:06, 30 May 2008 (UTC)[reply]

I suspect 'released to the public' means it is publically accessible, rather than being PD. Kind of like a library book.—RJH (talk) 22:38, 10 November 2009 (UTC)[reply]

As a NASA space telescope, I would think it would fall under the same rules as with Hubble. I think Hubble data is PD after one year. -- Kheider (talk) 01:37, 7 May 2010 (UTC)[reply]

Read Can we use this data for publications? -- Kheider (talk) 21:40, 13 May 2010 (UTC)[reply]

What happened?[edit]

What is going on with this thing? It's supposed to be fully operational, but there is seriously like no interest in it. InMooseWeTrust (talk) 20:03, 10 October 2010 (UTC)[reply]

Chronology and current status[edit]

It would be great to have a chronology of operations and a detailed status of the satellite systems and consumables. How long can it last ? Have the instruments degraded ? - Rod57 (talk) 09:35, 1 June 2012 (UTC)[reply]

One sensor (far-UV) failed in 2009. but NASA ran out of money! - Rod57 (talk) 05:23, 11 October 2021 (UTC)[reply]

What image sensor and filters[edit]

Images are presented here as blue but are they taken in monochrome ? over the full 135nm-280nm band? or through different filters ? - Rod57 (talk) 03:35, 14 January 2017 (UTC)[reply]

Compare with HST instruments[edit]

GALEX: 135–280 nm, across multiple detectors. Many of HST instruments went from visible down to 115 nm. - Rod57 (talk) 11:22, 11 October 2021 (UTC)[reply]

Was it too expensive to operate[edit]

Was it too expensive to operate, or was it not producing good science data ? Why was it judged not worth funding further operations ? Did it have unique capabilities (eg distinct from HST's UV capability) ? - Rod57 (talk) 01:33, 27 November 2020 (UTC)[reply]

How significant was the 2009 failure of the Far-UV sensor ? Where is the report that listed it as 8th priority out of 11 ? How much did NASA save by defunding it a year earlier than the experts recommended ? - Rod57 (talk) 05:30, 11 October 2021 (UTC)[reply]

Why did NASA decommission it a year after transferring ownership to caltech[edit]

Why did NASA decommission it a year after transferring ownership to caltech ? What did caltech do in their year of ownership ? - Rod57 (talk) 05:21, 11 October 2021 (UTC)[reply]

I agree. This is vague:

>On 17 May 2012, GALEX operations were transferred to Caltech.[7]

>On 28 June 2013, NASA decommissioned GALEX. It is expected that the spacecraft will remain in orbit for at least 65 years before it will re-enter the atmosphere.[3][2]
