A lot of work
For an Ocean Colour Scene...
The European Space Agency (ESA) is all a-quiver at the prospect of the second Sentinel-3 satellite launch, due this evening atop a Russian Rockot launcher. The spacecraft will ride to space at 1757 UTC on 25 April from the Plesetsk Cosmodrome in northern Russia aboard an elderly converted Intercontinental Ballistic Missile ( …
Converted ICBM's otherwise headed for the chop shop are relatively cheap. It's probably also cheaper for Russia to hand them to Roskosmos, convert the payload & launch, than leave them to the military to decommission.
I don't recall if it was the SS-19 specifically, but there are some heart stopping videos of Russian ICBM launch procedures; and how they clear the silo. Rather than fire the main engine in the silo, a brief solid fuelled pop puts the rocket above ground; leaving the rocket to briefly fall back while the main motor engages.

This is standard procedure for solid-fueled missiles; it allows them to be launched from tubes, either in a compact silo or from a sub. It's only possible with solid-fueled boosters because the solid fuel is structural - the tanks of a liquid fueled booster would collapse if you tried to accelerate the booster out of a tube at the same rate, to get it clear of the tube before ignition.
The early liquid-fueled silo-based boosters, like Titan, needed much larger silos, with enough vent capacity to allow the rocket exhaust to escape.
So if various bits of the Russian kit are possibly a bit flaky and unreliable
2. Obligations under various weapon or dual use platform disposal programmes. During the late 80-es Eu and USA signed a number of agreements with Gorbie. These agreements mandated that some of the old "world destruction" tech will be converted for civilian use and bought. For example all SS20 mobile launcher-erectors were converted to building site cranes.
We do not want to renege on this - the tech is already at disposal sites from where it tends to go walkies. An example here would be the same SS20 erector launchers converted into cranes. A number of them were not bought as promised so you can see them being driven past Kim Fat The Turd with Nork ICBMs on them.
Given a choice of completing the contracts as promised or them being bought as "cucumbers" by the Norks, it is probably better to live the Norks on a cucumber-free diet. In fact, everyone is pretending that none of the companies involved on the Russian side is under sanctions. Probably for the better too.

Fair enough, but why risk an expensive satellite? Surely the risk is lower and the cost not that much difference in using a more trustworthy launch system for the satellite, and then paying the Ruskies to launch a completely useless, vainglorious payload to use up the stock of old ICBMs - for example, strap four together and launch a car into space. Or just the one to loft some Playmobil astronauts. Or Rupert Murdoch with a one way ticket (no space suit, just poke the nose cone up his arse and light the blue touch paper).
Surely the risk is lower and the cost not that much difference
The cost of moving a satellite from equatorial or near-equatorial orbit as launched from Guiana to a polar orbit can be quite substantial. The back-of-the-fag-packet math needed exceeds my orbital mechanics knowledge. I suspect that you may be looking at designing a new third stage just for that which in turn screws your reliability math outright.
Initially, when Russians declared that they will open Plesetsk for commercial launches 20 years ago everyone laughed - how are you going to launch to GST from that. That is no longer the case for observation satellite launches. Nobody is laughing. A lot of gear went up from there and is in constant use.
As far as Murdoch - I am happy to pitch in if someone crowdfunds that. Can we add Tony The Bliar and the Witch of the West for a ride too?
As far as empty launches, I think you underestimate the element of national pride involved. While loading Murdoch into a payload fairing is something they will definitely agree on, loading playmonauts even if we pay them double the rate - do not think so.
Lies, the devil can't retire (have you never heard thr documentary "old Harry's game" On the wireless? It goes into detail about this vwry matter) next you'll be telling us media companies don't do it for the common good and all politicians aren't beacons of truth and trust)...
Interesting to read about an ex Soviet missile being used successfully. This morning I was listening to an old edition of the QI "No such thing as a fish" podcast and they had a fact about in the event of WW3, lot of Soviet missiles would have been inoperable - apparently the crews in the missile silos were in the habits of drinking all of the fuel.

The legendary Russian metabolism. Being able to drink DMH and hydrazine. Using gherkins pickles in fuming nitric acid as a side dish. Is it so difficult to spot bullshit for crying out loud? Ethanol is not used for rocket fuel. Its energy density is too low.
Most old models were liquid fuelled. In the event of Ww3 the launch readiness was under 5% because of that. More than sufficient to bequeath the earth to the cock roaches though.
This was noted as a problem by John Clark in his famous book "Ignition" --- see one of my blog posts from a couple of years ago for this and a few more quotes: https://hughpumphrey.wordpress.com/2015/01/11/rocket-science-it-should-impress-you/
I heard recently that "Ignition" is going to be re-published legitimately; I suspect that more than one Reg reader will want a copy.

The QI 'fact' sounds a bit suspicious - like quite a lot of their 'facts'.
Early Soviet missiles, like the R1 and R2, used alcohol as fuel with liquid oxygen as the oxidiser. From the R7 onwards they briefly switched to kerosene and liquid oxygen. However, these rockets didn't fly from silos because the cryogenic oxidiser couldn't be stored in the rocket for extended periods.
The Soviets event settled on storable liquid rockets running on unsymmetrical dimethylhydrazine fuel (which smells like rotten fish and is incredibly poisonous), and any of dinitrogen tetroxide (incredibly irritating to the lungs and throat), red fuming nitric acid (like nitric acid, but worse) or liquid oxygen (hard to keep in a glass). These rockets could be put in a silo, but have a nasty habit of poisoning their operators or spontaneously blowing up because someone coughed too hard.
Though I can think of one case where a rocket was filled with vodka. The massive Proton rocket was identified as the rocket that could carry cosmonauts around the Moon before Apollo could land on the Moon. The first mock-up was sent to Baikanor for testing during the middle of winter. Normally, this would have involved filling the rocket with water, but the temperatures were so low, that the Soviets used 40% ethanol - 15 rail tanker cars of the stuff. What happened to the alcohol afterwards is not recorded. As it happens, the Proton was delayed and there were problems with the planned Soyuz variant capsule, so the manned Moon missions never happened. A series of unmanned probes - Zonds 4 to 8 *were* flown between 1968 and 1970s with varying levels of success.
There were plenty of stories during the Cold War of Soviet troops drinking antifreeze which can contain alcohol.

Generally unnecessary for people serving in what is now Russia Space forces - missiles, National AA, Radar, etc.
All of these had allowance of alcohol issued for cleaning optics, contact surfaces and screens. There were plenty of attempts to switch to isopropanol for that, all of them unsuccessful. It did not "clean as well". Cough, cough, cough...

I did not know the Proton story, but that puts the issues with the launches during that year into an interesting perspective. I am pretty sure none of that valuable commodity "went to waste".
When I was a lab rat, we had a Russian PhD student. When he arrived he couldn’t get his head around Ethanol being freely available in the labs. It turns out that in Russia, Ethanol etc. was locked up by the PI to stop people drinking it. He also claimed that the 95% pure stuff is “better for you” than the ultra pure Ethanol as it contains fewer impurities - strangely we never tested his claim!
He also claimed that the 95% pure stuff is “better for you” than the ultra pure Ethanol as it contains fewer impurities - strangely we never tested his claim!
He is right. Ethanol left "to its own devices" will absorb moisture from the air to ~ 95%. It is also impossible to purify ethanol beyond this by distillation. You hit 95% and that is where the story ends.
Ethanol with higher purity than that has been dried. Even if the drying method was "safe", the dried ethanol itself like most ultra dried volatile organics becomes vulnerable to some very nasty reactions with oxygen from the air, uv light, etc resulting in various peroxide impurities. Ethanol is nowhere near as bad as for example furan or ether - those may explode from build up of peroxide impurities in their ultra-dry form. While not "as bad" it is still bad. You really do not want to drink the sh*t which has been extra-dried, especially if has been left around for a while and god forbid exposed to sunlight while extra-dry - it is like licking agent orange.
That is why the bottles for the ultra-dried stuff are always made out of dark glass by the way.
I wasted a chunk of my MSc lab rat days distilling stuff. You could not do anything in the area I worked on without wasting half a week on getting enough distilled ethanol, acetonitrile, ether, etc. It was pretty useless by the beginning of next week so you had to start from the beginning once more.
1) Its a German company, launching from a Russian base.
2) The launcher is quite reliable
3) The programming of the 3rd stage has been dodgy in the past. Programming errors are much easier to fix than hardware issues, and 10 successful launches in a row indicate that they have them solved.
4) Its much cheaper than an Ariane launch, and the satellite doesn't need the capacity that Ariane offers.
If it's cheaper to use a Rockot than an Ariane, then Rockot it is. Ariane has a line of customers out the door. ESA et al will have to queue like everyone else. Clearly the queue at Eurockot (a JV of the Russian Cosmodrome and Airbus) is somewhat shorter.
And Plesetsk is closer to the polar orbit that the satellite needs. So... 1+1=2.
So if various bits of the Russian kit are possibly a bit flaky and unreliable, why use them? Was the contract signed before the debut of SpaceX? And why not use Ariane?
Because this satellite weighs less than two tonnes and Ariane 5 is good for 16-20t to LEO. Ariane 5 is overkill for most missions - it normally launches pairs of satellites, but that in itself introduces the challenge of finding payloads who are going to a sufficiently similar orbit (and which need launching at about the same time/year) that they can sensibly ride share.
The Rockot is not really flaky - they have a good run of successful launches as mentioned in the article. It's the Proton-M which has been causing the Ruskies all sorts of issues over the last couple of years.
Why nor Ariane? The reason is the lack of a good Ariane launch site suitable for polar orbit. You save a lot of fuel launching close to the pole (less perpendicular speed to to kill). Additionally the site needs to have launch corridors aiming towards North (or South). Guyana is ideal for geosynchronous satellites, not ones in polar orbits.
I know some of the ESA guys who oversee the launches in Plesetsk. I've learned that the launch site is just a forest secured with barbed wire and the only place one can go is a bar. So the French engineers had to learn drinking vodka.
Why not use the Norks now defunct ICBM's? Since they're not going to use them to rain down nukes across America, it'd be a good source of income for them !!! ..... Blockchain commentard
