“Who can say what contraption the future will bring?
There can be not a doubt, some more wonderful thing.

And if anyone ventures the future to scan,
Why indeed should it not be your old Weather Man?

Have you noticed how often in times that are past
We have used new inventions to improve the forecast?

Television is coming, it is not far away;
We’ll be using that too in a not distant day.

Photographs will be made by the infra red light
That will show us the clouds both by day and by night.

From an altitude high in the clear stratosphere
Will come pictures of storms raging far if not near

Revealing in detail across many States
The conditions of weather affecting our fates….” By George Mindling (Weather Bureau), 1939

“The designers made the Little Joe booster assembly to approximate the same performance that the Army’s Redstone booster would have with the capsule payload. But in addition to being flexible enough to perform a variety of missions, Little Joe could be made for about one-fifth the basic cost of the Redstone, would have much lower operating costs, and could be developed and delivered with much less time and effort. And, unlike the larger launch vehicles, Little Joe could be shot from the existing facilities at Wallops Island.”

While the Mercury 7 were fulfilling their roles as symbols of space exploration, Korolev once again was offering the real thing. He now prepared to undertake the most demanding mission yet. The mission that would accomplish the next step in Korolev’s program of lunar exploration. He would attempt to photograph the far side of the moon.

The launch vehicle for the Luna E-1 series was a modified R7 named Vostok. The Vostok had three stages. The first and second stage were the standard R-7 which we covered in Episode 9. A 5.1 meter long by 2.4 meter diameter third stage was added to the top of the R-7. The third stage weighed 1472 kg and was capable of delivering 54.5 kiloNewtons or 12,252 lbs of thrust. This was the probes booster stage that gave it enough speed to escape Earth’s gravity.
