Talk:786: Exoplanets

There is no indication that SG:A is the city-ship being referenced. Atlantis does not fly by Orion-drive and is in no way the first Sci-fi reference to City ships. They go back at least as far as "Cities in Flight" by James Blish and possibly further, although I've found no evidence of this. -- 99.111.149.90 (talk) 12:04, 19 January 2013‎ (UTC) (please sign your comments with ~~~~)

Also note that this comic is no. 786, which is the amount of known exoplanets. -- ‎152.93.147.10 (talk) 09:17, 21 February 2013‎ (UTC) (please sign your comments with ~~~~)

But this was released 2 years earlier than that count; still it's interesting factiod... Mark Hurd (talk) 11:07, 13 April 2013 (UTC)

Footfall by Larry Niven is the best example of city-ships in line with Project Orion. Basically the bigger they are the better. Big metal plate with a city on top and nuclear bombs exploding underneath. And the project started in the 50s. [1]--173.245.54.11 04:53, 11 May 2014 (UTC)

Before restarting Orion, why not start with a more modest goal: a facility to assemble spacecraft on the moon from parts made on Earth? Even without the mining, it'll mean we can launch a craft from Earth in several smaller rockets instead of one big one. Promethean (talk) 01:30, 14 February 2018 (UTC)

Look at you, predicting the Artemis Program... 172.69.42.44 03:00, 11 February 2021 (UTC)

Not to have a conversation with three-year pauses, but why not assemble the ship in orbit? That way you don't have to use up large amounts of propellant to land ships in the moon's gravity well, then boost the completed vessel away again. Nitpicking (talk) 01:19, 5 September 2021 (UTC)

We don't have the infrastructure yet to build things in space, the US is working on it but these things take time, and planning--Lackadaisical (talk) 19:12, 6 September 2021 (UTC)

We don't exactly have the infrastructure to build things on the moon, either, you know. It would still be easier in space. Nitpicking (talk) 01:03, 7 September 2021 (UTC)
