Part 2 of Asif's Sputnik series:

Sputnik remembered: The first race to space (part 2)

[Part 1 was published last week.]
Success with the R-7?

Although Korolev had obtained permission to launch PS-1 back in February, the launch was not a foregone event. In his letter to the government in January, he had noted that a satellite could be “launched immediately after the first successful launches of the intercontinental missile.”1 A government document specified this as “one or two” successful launches.2 As is well-known, there were several consecutive failures of the R-7 missile in the summer of 1957: one on May 15 exploded 104 seconds into its ascent; a second rocket never left the pad despite three consecutive attempts on June 9, 10, and 11; and a third R-7 was destroyed 33 seconds after launch on July 12. If there had been hope of launching two PS-1-type satellites in the summer, that hope was lost. The mood at Tiura-Tam was hitting bottom by the time that a fourth R-7 was brought out to the pad. Engineers, soldiers, and even government bureaucrats were all desperate for a success.

There is a new special project by Russian Archives remembering Sputnik (a little late - but anyway): http://sputnik.rusarchives.ru/
One color photo (http://sputnik.rusarchives.ru/dokumenty/start-rakety-nositelya-s-pervym-iskusstvennym-sputnikom-zemli) allegedly showing the launch of PS-1 attracted my attention. It looks like taken during twilight. But the launch of PS-1 took place at night - on the other hand the nose cone of the launcher looks like the one of PS-1. So, what do we see here?

that picture is believed to depict the launch of Sputnik 2. see for example the right sidebar of http://russianspaceweb.com/sputnik2_mission.html
the nose looks more pointy than that of Sputnik 1, and the sunset timing matches the 5.30 PM Moscow Time launch.

Yes, I think you're right. I forgot about those (color) photos. And the shape of the nose cone in the b/w photo looked slightly different to me. But that's an optical illusion, probably. The 'kink' in the plf contour is hard to recognize.
