Three visions or one?

[edit]

I've removed the claim that the three stories take place in a single future, because I think it's wrong. I've added one reason to the article - Earthlight should come last if it is a single future. But The Sands of Mars include a significant discovery on Mars and also a significant event near it. Neither of these are mentioned in Earthlight.--GwydionM 17:13, 26 July 2007 (UTC)[reply]

My copy (1977 paperback) says the copyright is 1935 yet it also lists the first edition as 1955. What's the deal? What do we want to report in Wiki? FusionKnight 00:25, 19 October 2007 (UTC)[reply]

Clarke was born in 1917, so 1935 is very early. Possibly it is something he wrote as a teenager and then rewrote and expanded 20 years later. Worth looking into, but meantime the entry should stand.--GwydionM 17:11, 19 October 2007 (UTC)[reply]

I added the Tuck reference which lists the first publication of the novel as 1955 and also states that the novel is an expansion of a story which first appeared in the August, 1951 issue of Thrilling Wonder Stories.--Rtrace 16:25, 3 December 2007 (UTC)[reply]

The article states "The story describes regions of heavy metal resources concentrated in certain areas beneath some of the Lunar maria. This anticipates the later discovery of mass concentrations or Mascons, by surveys of the Moon carried out prior to the Apollo landings by the Lunar Orbiter missions." This is sort of on the right track, but my objection is that I think that no one ever claimed that the mascons are caused by heavy metal deposits, at least not the type we have on earth with distinct veins of ore. They are probably caused by rebound of the surface after a giant impact, which pulls denser mantle materials closer to the surface. The mascons are nearly always centered on impact basins, but not necessarily on maria, which have different origins despite their usual colocation. Jstuby (talk) 16:39, 25 September 2017 (UTC)[reply]
