> The Venera 14 craft had the misfortune of ejecting the camera lens cap directly under the surface compressibility tester arm, and returned information for the compressibility of the lens cap rather than the surface.
I've just read the Wiki on the Mars Climate Orbiter and it explains the disastrous implications of that mistake. What's tragic about such errors is that the US keeps repeating them, Hubble was another very expensive Imperial/Metric fuck-up even though it was recoverable.
I've often had debates with Americans about Imperial versus Metric when I was in the US and their retort is usually along the lines "why should we give up God's own units for that nasty French stuff?" or words to that effect.
They gave other specious arguments too, such as cost of new tooling would be prohibitive. That's rubbish† of course (certainly in the grand schema of things as the long-term benefits far outweigh initial costs).
Well, anyway, by the looks of it God is on the side of the French!
What many of us outside the US find odd and can't figure out is that in its early days the American Republic was hand-in-glove with the French against that horrible Imperial island, so why did it reject the French system?
Yes, I know of the early attempt at metricization and the loss of weights and measures at sea whilst in transit from France to the US but given its impact that's pretty paltry excuse.
It really is time you guys caught up with the rest of the world. Surely, it's getting a bit too expensive to continue to lose spacecraft to whims of measurement.

† Check how well Australia's metric conversion went some 50 years ago. It's a textbook example of how to go about it correctly. I know, I live there—we fuck things up more often than not but this one we got AOK right. If you ask kids at school today what various Imperial units are they'd likely say they've never heard of them.
> Great teacher, but to have your life's work go up in smoke like that is brutal.
No doubt. I hope everyone's doing alright.
I tend to reject any narrative about the Soviets which makes them not sound like humans. They weren't all idiots or sociopaths: they understood, just like we do, that people make mistakes and that if you punish mistakes too harshly, people won't want to risk working with you. The Soviet government punished dissent harshly--but if you were working with them they weren't typically so foolish as to punish honest mistakes with a stay in the gulags. In fact, technical fields like their space program (and, for example, infrastructure programs) were safe havens for intelligentsia, where some criticism of government was tolerated because it was understood that criticism from people with technical knowhow was necessary to progress Soviet goals.
There are exceptions I've found, but I tend to think those are the result of a few people with too much power making bad decisions, rather than a pervasive cultural norm.
None of this should be perceived as a defense of Soviet totalitarianism. Stalin has the highest body count of any dictator by a wide margin, and that's totally reprehensible. All I'm saying is I think he killed political dissenters, mostly, not allies who made mistakes.
Sergei Korolev, a famous Russian rocket designer (who was later responsible for launching a first satellite and first human space flight), had to go through the prison and labour camp. In 1938 he was head of a laboratory for jet propulsion (mainly for development of weapon), and as jet engines were not well studied, experimental models often failed with explosions. After another failed test, several laboratory employees were arrested, and after they testified, Korolev. They were charged with sabotage - creating a secret anti-Soviet organization with the purpose of weakening Soviet defence. After series of interrogations, during which he had his jaw broken, he admitted the guilt and soon was sentenced to 10 years of work in labour camps [1]. The sentence was later reviewed and he was transferred to a prison where he was allowed to continue working on jet propulsion.
Another example is Andrey Tupolev - Soviet aircraft designer ("Tu" series of planes is named after him). He was also charged with sabotage (conspiracy to slow down aircraft development in USSR) and espionage during Stalin times and had to design his planes in a prison [2].
After Stalin death, both Korolev and Tupolev cases were reviewed and they were admitted not guilty.

> Its landing module, which weighs 495 kilograms (1,091 lb), is highly likely to reach the surface of Earth in one piece as it was designed to withstand 300 G's of acceleration and 100 atmospheres of pressure.
Awesome! I don't know how you can design for 300 G's of acceleration!
Aerospace is awesome.
For well under a second though, typically artillery muzzle velocity is, what, two to three thousand feet a second?
Still, it’s wild that guidance electronics and control mechanisms can survive that sort of acceleration.
- barrel length (x): 5.08 meters
- muzzle velocity (v): 827 m/s
Assuming a constant acceleration γ, x = γ * t² / 2 and v = γ * t
Hence:
- t = 2 * x / v = 12.29 ms
- γ = v / t = 67316 m / s² = 7000 G
A bit lower than 9000 G, but in the same ballpark.
Certain rounds, like Excalibur (https://en.wikipedia.org/wiki/M982_Excalibur) or BONUS (https://en.wikipedia.org/wiki/Bofors/Nexter_Bonus), are sophisticated and are able to cope with such accelerations.
It's not like you can tell whether you're going slow or fast, in one direction, the other direction, or even just standing still, if you close your eyes.
Starting to get to the range where a timezone would be helpful!

So it would be ironic if glorious past reached through the space to hit those who idolizes it, because they idolize not the historical past but the alternate history past. Reality strikes back.
The Moscow military parade is meant to demonstrate the neo-imperial Russian military might, on the 80th anniversary of the USSR conquering half of Europe. That's the way it is presented, with slogans like «Можем повторить» i.e. “We can repeat it”.
The former striking the latter would be a bit like a terrorist accidentally blowing up on a bomb of their own making.
Why would this be? Is the solar wind strong enough to affect the velocity of a dense object such as this?
I wonder if the producers of that show knew about that failed mission, and that this was actually really in earth orbit, when they wrote that episode.
Irina: You don't understand. I designed that probe for Venus. Venus Oscar. A planet with temperatures of 900 degrees, 300 mile per hour winds, pressures up to 90 earth atmospheres. Even a bionic man couldn't survive under those conditions.”
and now it looks like it might just survive anyways. but then according to the article there also seems to be a second (identical?) model. so maybe it's not that important, except for maybe material analysis what does 50 years of exposure to space do to the material.
Even the Space Shuttle wasn't necessarily a perfect fit for the job as-is. Hubble was serviced many times, but it was specifically designed for on-orbit capture and servicing by the Shuttle. Before they decommissioned the shuttle they actually had to install an extra piece of hardware to make it feasible to capture and de-orbit using future non-crewed spacecraft. And even then that's just to make sure it crashes in a safe place, not to bring it home intact.
There was also a mission to service a satellite that wasn't designed for the purpose, and they had a really hard time capturing it and very nearly had to give up after days' worth of failed attempts. It finally took simultaneous EVA by three astronauts to coordinate a successful capture (one to grab it by hand, two to get it onto a specialized adapter rig built just for that satellite so that the Canadarm could hold it), which is quite a thing considering that the Shuttle's only designed to allow two people on EVA at a time.
This craft is likely tumbling, which I presume would make it unacceptably dangerous for a crewed mission (and certainly rules out anyone just going out there and grabbing it with their hands), in addition to making successful capture that much more difficult.

If you know Elite, it has space stations where you dock by going inside, while matching station's rotation. That's only in one axis (and note the hangar goes through the axis of rotation, i.e. centre of mass). To add rotation around another axis would make the task impossible.
When I worked "on Mars" there was a "flight spare" copy of a Viking instrument which was the predecessor to the one we were working on, and of course it was encased in Plexiglas as a museum piece, but it was truly a redundant copy, as NASA was into copying everything they sent into space, (what was the saying in Contact? "Why have only one, when you can buy two at twice the price?") so that if anything needed to be tweaked, or went wrong, they would have this copy on the ground that they could experiment with to their hearts' content.
SpaceX's Dragon 2 easily has enough cargo capacity to bring it down (~3 tons vs 0.5 ton), but there's still the question of intercepting, capturing, and securing it in Dragon's cargo bay. That would still cost something north of $100m to recover the lander.
The lander would easily fit into the unpressurized cargo bay (the "trunk"), that is typically used to launch various vacuum-bound payloads alongside pressurized cargo inside the capsule. However, for a return from orbit, the trunk cannot be used - it is not protected by a heat shield, and is ejected before re-entry.
You are correct that the return payload mass of a Dragon would technically allow it. But you'd need to somehow get the captured object _inside_ the capsule, which may be possible via the EVA front hatch for something smaller, but not 1m in diameter like the Venera lander.
Starship should be able to do it, since it is fully protected by heat shielding and returns in one piece, not ejecting any modules in orbit. But that's quite a while from being operational yet.
*(They're both at exactly the minimum inclination, 51°, achievable by a Soviet launch from Baikonur).
https://en.wikipedia.org/wiki/STS-32 brought back the Long Duration Exposure Facility experiment, a bigass science probe the size of a small school bus.
There are still missions that are classified that could have done so as well.
It was something the shuttle was designed to do, with the 60-foot cargo bay requirement and the ability to bring back the mass it flew with coming specifically from the military.
That's very interesting. First time I heard about it. Thanks for the reference!

And Soviets were wondering why their satellite numbers were not growing...
National existential crisis? They'd probably take Dragon and figure out how to make it work.
I don't know what value can it have to be studied since it never left low earth orbit (albeit it was there since 1972), but I know it would be a cool addition to any museum that may host it.
But at this point none of the remaining shuttles are in an operational state.
Maybe you are thinking of the X-37 which is operated by the space force?
Thinking about the elevator in our commie block, it would have given a heart attack to a western European. Instead of having double doors to keep us safe from the moving wall, it had pads on the bottom and top edge so if your hand or leg is stuck, the pad will be pushed and the elevator will stop immediately. Also there was a tiny cabinet door on the right side so you can access the mechanism to force open the door or force move/halt the elevator. As kids, we would be experimenting with those mechanisms. They worked every single time, no legs or arms were lost.
Neah, paternoster is quite a common elevator design in the west: https://en.wikipedia.org/wiki/Paternoster_lift
I would have thought the name was related to the users praying before entering to increase their chances of surviving the ordeal.
> Space law required that the space junk be returned to its national owner, but the Soviets denied knowledge or ownership of the satellite.[8] Ownership therefore fell to the farmer upon whose property the satellite fell. The pieces were thoroughly analyzed by New Zealand scientists which determined that they were Soviet in origin because of manufacturing marks and the high-tech welding of the titanium. The scientists concluded that they were probably gas pressure vessels of a kind used in the launching rocket for a satellite or space vehicle and had decayed in the atmosphere.[9]
I wonder how space law works when the national owner (CCCP) no longer exists? Does it go to Russia? Kazakhstan?
UN Security Council seat: yes, of course! What an ignorant question.
Responsible for the damage done by the USSR in other countries: certainly not! How dare you!
There was also a bona fide telephone booth in there, in wood and glass, and I absolutely went nuts, actually needing to place a phone call. But I couldn't quite figure out whether it would open and admit me, or if customers were supposed to be fiddling with it at all, or whether it was only a showpiece. So that exploration will wait until the next time I drop by.
This thing spent 50 years in high earth orbit. Everything will have received a huge dosage of radiation along with periodic freezing and boiling temperatures.
Something may have survived, life is crazy like that, but it's unlikely it will be a dangerous pathogen to humans. In fact, surviving life will have likely adapted to eat any of the pathogens.
But also technically not impossible. For example if the dormant microbes react to prolonged microgravity and radiation in ways we don't understand, perhaps it brings back something we haven't seen before
Could be a fun science fiction plot
It sounds about the same as if I used something like "Joe" to refer to a William.
If you want to troll Putin, call him Vovochka.
