Historically we have only maintained lists up to one or two years into the future, however in the last few months a large number of articles for more distant dates have sprung up. We're currently struggling to maintain the 2011 and 2012 lists, and with today's creation of 2019 in spaceflight, I think we need to look at exactly how far ahead we can feasibly have articles at this time. 2014 in spaceflight was deleted last year because it was too far in the future (see Wikipedia:Articles for deletion/2014 in spaceflight), however it has since been recreated. Given the difficulty in mainaining a near-term launch schedule, I think there is little or no merit in trying to have a long-term schedule, so we should not try to create such articles past the end of the next calendar year (i.e. 2013 should not be created until 2012, 2014 should not be created until 2013, and so forth). With regards to the DSR sections, which in many cases are the only content in these pages, whilst the dates are less likely to change once spacecraft are in flight, some of the dates are extremely vague, and others are dependant on other factors, such as launches or departures from the orbits of other celestial bodies. I think that maintaining a list more than one or two years into the future, let alone eight years into the future, is optimistic at best. Should we look to delete, merge or move to a sandbox some of the more distant articles? --W.D.Graham(previously GW) 17:47, 20 December 2011 (UTC)
I didn't know that this has been debated. Template:TLS-L has got some red links, and I was lured to paint them blue.
Regardless of the Earth is blown up in a nuclear war, Rosetta will reach 67P/Churyumov-Gerasimenko in May 2014, and New Horizons will fly by Pluto 14 July 2015. However minor space agencies have a tendency of saying "yes, we are going to set a man on the Moon in the year 20XX". It will be a problem to make a distinction between intentions and solid plans.
The problem with that would be that every time we create a new article, we're left with the old title, and there isn't really anywhere to redirect it. How about just putting any additional DSRs in Timeline of spaceflight itself, and limiting them to spacecraft which have actually launched? --W.D.Graham(previously GW) 19:12, 20 December 2011 (UTC)
If you look at Timeline of spaceflight — is that what you mean? Should there be a warning at the [2014 etc. in spaceflight] with the policy, in order to avoid premature writing? --Regards, Necessary Evil (talk) 00:16, 21 December 2011 (UTC)
I've made a couple of small tweaks, but that was almost exactly what I had in mind. I would suggest we redirect the other pages there, and use a comment to tell users not to recreate them. I might look into having edit notices put onto the pages as well. Finally, we should probably look into setting up a sandbox to house spacecraft which have not already launched. --W.D.Graham(previously GW) 09:02, 21 December 2011 (UTC)
50 years ago next month workgroup coordination template
I propose creation of a "50 years ago next month" template somehow automatically driven by the timeline of spaceflight data, which could be transcluded in Wikiproject and User namespaces. This would focus the attention of editors on articles which might be spruced up prior to the time when readers will be interested in them.... (sdsds - talk) 08:54, 29 December 2012 (UTC)
