Bingo:

"Zwicky was proud of having contributed essentially to the 1957 shot of the first human bullet into space, an object manufactured on earth which should leave the gravity of earth for ever. These experiments were done with German V2 rockets, which when reaching the highest point would shoot a bullet away. These experiments with 'artificial meteors' have begun shortly after world war II and were first unsuccessful."

From here.

I'm assuming I got the correct answer, so here's my question:

The Kremlin and a celestial object have something in common. Name the object, and explain what they have in common.

We have a Bingo. Althought, the question called for the amount of time it took from the time of Sputnik's launch. The answer is 12 days! I find that quite a quirk of history.

The first atempt was in 1946, long before Sputnik. They had about 30 telescopes out there including one loaned from Palomar. Also, Palomar was watching from 1000km, too. The explosives never fired.

However, it was published in the New York Times. I would be curious the reaction of the USSR when the read it.

It was Oct. 16, 1957 when the sucessful event took place (at least according to him). They had made measurements of the blasts velocities which exceeded 30km/sec for the gas and about 14km/sec for metal slugs, apparently. [11.2km/sec is the escape velocity.]

More here and here.

Well, that was fast... Your turn!

OK

How about

There is a link between Gridiron, Grasshoppers and Guildford. Itś a bit silly and should be measured under a hot sun, preferably with a rum and coke.

I might have stumped everyone again. BTW this links into problems with the post on Ascension. Come on everybody, the clock is ticking.

More obscurely hums a tune that sounds like a cross between On Ilkley Moor Bahtát, the Lincolnshire Poacher and the Surrey with the Fringe on Top.

You bet you did...

Royally so...

Hitchhiker is all I can think of. Ford Prefect claimed to be from Guildford. Your hints also remind me of cricket ... in other words, I'm stumped!

seems like you're on to something except I still wonder if the answer is astronomy related.

Here's a mention of the Guildford Grasshoppers

The answer is as definitely astronomical as a sextant...

Itś time for an answer

Greenwich is a substantial clue, as is Barbados.

Something to do with John Harrison's chronometer? But H4 was his masterpiece?

Harrison

Very much the right track. Just need to link it all up...

Gridiron: "Harrison at length composed a frame somewhat resembling a gridiron, in which the alternate bars were of steel and of brass, and so arranged that those which expanded the most were counteracted by those which expanded the least. By this means the pendulum contained the power of equalising its own action, and the centre of oscillation continued at the same absolute distance from the point of suspension through all the variations of heat and cold during the year."

Grasshoppers: "[Harrison] invented the “grasshopper” escapement, a new form of deadbeat escapement for clocks."

Guildford: ??
