The thread for space cadets!

...(exploding rocket)...
In German news they only talked about a cruise missile and it sounded a bit like a Russian project Pluto or a broken arrow.
They were also not talking about a temporary radiation spike - just increased radiation.
 
City administration advised people to stay home and close windows on the day of accident. Locals saw people in protection suits who were evacuating the wounded. Looks like there was a significant but brief spike, because now people report radiation level is 3.6 ~10 mkR/hour which is lower than in Moscow.

Rosatom confirmed explosion and that 5 people were killed and 3 wounded. Looks like our authorities learned that providing information is better way to avoid hearsays and speculations, than trying to conceal accident.
 
I reread the German article and they were just guessing without any sources. If there is too many mights and mays they shouldn't publish it as news:old:
 
Second-round bids for the USAF launch contract were due today. Apparently SpaceX bid only the Falcon 9 and Falcon Heavy and not the Starship as they did during round one (which is speculated to be the reason why they lost that round). Blue Origin also filed a pre-award protest and stated that the competition is unfairly tilted toward established players like SpaceX and ULA.
 
Apparently the Russians were testing a nuclear device - but everyone says reactor OR engine, not a definite one or both. Seems to be due to a new weapons program that got kick-funded last year.

Overall, not much for space, other than the reactor. Just another weapon I hope is never used and I hope falls to the wayside.

THAT aside, apparently the Navy is rethinking their use of touchscreen controls after a string of collisions, where the controls are implicated. Ain't nothing wrong with analogue and fly/drive by wire if it works. Maybe that can be extrapolated to space (where touchscreens are seemingly everywhere in the new crewed modules) and scifi writ large.

Probably not. It's my understanding there is very little if any active flying by the pilots in the space capsules. They're mostly just selecting pre-made files to execute and tinkering with settings which are things better suited to touchscreens than massive banks of switches and buttons.
 
Was reading up on the story of a Cosmonaut today.
https://www.npr.org/sections/krulwi...3/cosmonaut-crashed-into-earth-crying-in-rage

The space vehicle is shoddily constructed, running dangerously low on fuel; its parachutes — though no one knows this — won't work and the cosmonaut, Vladimir Komarov, is about to, literally, crash full speed into Earth, his body turning molten on impact. As he heads to his doom, U.S. listening posts in Turkey hear him crying in rage, "cursing the people who had put him inside a botched spaceship."

This extraordinarily intimate account of the 1967 death of a Russian cosmonaut appears in a new book, Starman, by Jamie Doran and Piers Bizony, to be published next month. The authors base their narrative principally on revelations from a KGB officer, Venyamin Ivanovich Russayev, and previous reporting by Yaroslav Golovanov in Pravda. This version — if it's true — is beyond shocking.

Yeesh. :sad:
There is a button to listen to Komarov's last words. (0:38 to 0:47 I think)


The Starman book has been criticized for inaccuracies.
https://www.livescience.com/33177-npr-story-russian-cosmonaut-death-rife-with-errors.html
The book doesn't hit stores until April 12, but NPR's Robert Krulwich got an advance copy, and covered its heart-wrenching account of the accident in a blog post two weeks ago. Unfortunately, in so doing, he may have publicized an inaccurate rewriting of history.
NPR Opinion section! :cringe:
In most historians' views, the main point of contention is the fact that the only source for all the new claims in "Starman" is the former KGB officer, Venyamin Russayev, and no one knows who he actually is.

"All the new information comes from this new previously unknown KGB former agent and 'friend' of Gagarin, and has not been verified by anyone yet. Part of the problem is we don't know how reliable of a source this person is," said Robert Pearlman, space historian and owner of the space history and artifacts website collectSPACE. "No one has heard of him until now, and while that in itself shouldn't automatically rule him out as a source for historians, it does require the authors to verify his history and share that with readers."

Also more food for thought, is the U.S. Secretary of the Navy a troll?

bill Gunston , like the most eminent Aviation writer of his times held a patent on electromagnatic propulsion stuff in 1950s , let the patent lapse for some reason and spent his last years on ranting on Americans doing the B-2 . Does not mean there's anything real to anything .

my understanding on the Russian thing is it was an antiship thing , newspaper says Mach 11 .
 
NASA is kicking off an independent review of the ISS national laboratory. It seems they're serious about transitioning it to commercial operation in the near future and it doesn't help that the research has been so mismanaged that not much has come out of it relative to the cost. Though one huge problem is the lack of staffing caused by the early retirement of the shuttle and Congress's low balling of funding for its replacement over the last decade. The lack of astronauts on board to run experiments has been a huge setback to research and completely out of the control of the laboratory

uhm , you people are all sure about this ? They show some explosions on TV , with presumed geiger counters and whatnot and it looks like somebody has blown a Russian arms depot . Last time this happened in that area with international news coverage all the West jumped up and down on how that cut down Soviet Aggression for a while . 700 SAMs going up and if it was indeed 1983 , as ı remember reading it , it was most probably replacing ships that went to blockade Pakistan as India was invading due Pakistan's support to the Sikhs .

and them passengers are lucky , now that they pilots managed to force land in some corn field or whatever . Had Russia achieved anything of note recently , it might have been really bad .

edit : oh , correction , they are seperate incidents ...
 
SLS EM1 slipping to 2021. Future of SLS back to uncertainty - my bet is it won't survive this administration. I ain't no Muskovite but Musk may very well just drop Starship/Spaceship whatever on the Moon and NASA will basically be strong-armed into buying from him and the other TSTO/SSTOs that will crop up in the 20s.

Chandrayaan 2 has successfully entered Lunar orbit.

oh-kay , ı have read another one book and am now an expert on the development history of V-2 , as debated in this thread sometime back .

ı have now finished Dornberger's V-2 , some book from 1952 or 54 . Of course he says missile bombarment was the way to go :

"Ever since the huge bomber losses during the attack on England in 1940, my colleagues and I had been firmly convinced that defeat in the air on the western front could be prevented, if at all, only by the employment of guided missiles of very great range and effect In the long run the Luftwaffe would not be able to afford the continued loss of valuable flying crews.


The threadbare argument that our A-4 was too costly in comparison with the heavy bomber became more and more difficult to uphold in the light of experience over England. If, as accurate statistics showed, a bomber was shot down after an average of five or six flights over England, if it could carry only a total of six to eight tons of bombs during its active existence, and if the total loss of a bomber, including the cost of training the crew, were estimated at about thirty times the price of an A-4 (38,000 marks), then it was obvious that the A-4 came off best. It should have been only a question of time before this was recognized even at top level."



not forgetting to add that there were thousands of fighters on the ground but no fuel to fly them in 1945 , too ... Now that being able to provide CAS in 1944/45 could have still the "won" the war for Germany , by forcing the Allies to a standstill , however hard it might be argue to that end .

books by Military people tend to be self serving , especially those by people who have lost . But having the benefit reading some previous book , ı can confidently , you know , rant . In the first place the desire for Peneemünde to become "profitable" post-war is seriously apparent , trying to achieve a monopoly situation in "space" travel . One can understand a remote test site counter-espionage wise , but one day Adolf would want to invade Sweden and what would stop Swedes to bomb the centralized factory ? This is also a probable basis for the reference that there would a winged V-2 (later with pilots on board) and its A-10 first stage would have parachutes to make it land in the sea , with my really limited research never seeing anything like this before . V-2 as a warloser ? The first book had given the idea of Inertial guidance was a "thing" , with some Austrian expat having very high offers that could not be fielded in a weapon , even if his torpedo stuff were still deadly . This book offers some "not-one-of-Peneemünde" guy (a German general assigned later) suspecting it was heat that made the V-2s break up , only noticed when the tests were taken to Poland . So he wants glass wool covering for the Oxygen tanks and it adds some rigidity which helps , so they reinforce the missile shells . Had the RAF not bombed Peneemünde , they might have saved a couple thousands of lives ; and one can only suspect the raid happened because London received intelligence Hanna Reitch was visiting !


it being 1950s one must indeed forgive Dornberger for omissions . When V-2 starts to show promise , people try to take it from Peneemünde :

"We would transform Peenemunde into a stock company with limited liability. The entire capital of the company would remain for the present in the hands of the state, while the firm would be managed by a large concern acting as trustee -for instance, General Electric, Siemens, Lorenz, or Rheinmetall- with a view to transferring the plant, after amortization of the capital invested, to the possession of the firm"


A truly monstrous scheme!


"Are you aware," I inquired innocently, "that the value of Peenemunde, including everything spent on the place so far, is several hundred million marks? The interest payments and amortization quotas could hardly be a temptation to industry."

"We already have acceptable tenders ... We would make a cut in capital and declare assets of between one and two millions, letting the rest go."


What a charming idea! You take an investment running into several hundred million marks and turn it, by a "cut in capital," into a bargain of between one and two millions. Good business!


"Is it your opinion, then," I replied, "that this purely experimental plant, which has done nothing but cost money so far and has no facilities for mass production, will ever show any sort of profit or even pay for itself?"

"If it were associated with a big concern which could manufacture elsewhere as well, I consider it perfectly possible. Development costs would then be allowed for in the figures for quantity production and charged up."


It was incredible that I was dealing with officials and not ordinary swindlers. Public funds are of no account if you are set on doing the state, that is, the people, out of control of a business!



you know , Peneemünde does not have a factory despite the years long insistence , denying Dornberger what he wants and he is nicely accusing people trying to do what he couldn't as a not-yet-retired officer . To deny that he proposes to start a company , Adolf Hitler Limited ... Adolf does not bite and Peneemünde will indeed become a private company later , to prevent SS swallowing it in whole . People interested enough will know SS once arrested von Braun for working on space travel and not the war ...

oh , General Electric ? A couple of pages later that will turn out to be AEG , the German equivalent . As one can never follow the money and stuff , ı actually checked wikipedia if AEG was a subsidiary of GE . Turned out AEG was established to sell Edison lamps before diversifying and stuff . It gets better as the AEG guy arrives to check Peneemünde , discovers the rocket people know electricity better than AEG , making him say : "Now, after seeing the work you have done and the problems you have tackled, I shall ask you to help the German electrical industry! " As these are the times the locomotive czar of the Reich is busy trying to grab the V-2 from its inventors , Dornberger is perhaps agitated in remembering a decade later ? Or is it bitterness or something as GE (through Project Hermes) sits tight on the Nazi rocketmen while American industry learns stuff on its own , decreasing the "power" of the von Braun team ? ı understand the early years were not exactly glorious for the German emigrees in Alabama and stuff . Or is it even real , Nazis reaching out to Corporate America , offering all them patents if America quits the war , just as the Allies are getting into the stride ? As an example of sorts , the SS finally collected all the biggest engineers down to South Germany where they could be captured by Americans or maybe shot as a last resort .


and of course , one indeed has to explain why they were all SS in the end , with the Mittelwerke and death camps and the whole thing . This is provided by pages and pages of talks with Himmler . Who strangely doesn't "sound" that insane in Dornberger's reminisence ; with gems like Russian worker loves his status while the Westerners are just lazy . If Stalin makes butter instead of cannon there is no way the West can cope with the cheap imports , you know the China model since the 1980s . So them Russians perhaps must be forced to stay in arms production , perhaps helped by giving Peneemünde experts far more visible and profitable jobs ? Yeah , my fault that Sputnik , without it von Braun would be a nobody by 1970 ...
 
There was never any real intention by the Germans to do anything with Peenemunde except design more weapons. Von Braun harbored some fanciful notions of peaceful space exploration but no one took them seriously and he actually got in trouble with the SS because of them. If there was any interest in privatizing Peenemunde, that interest was entirely subsumed by the war effort.

The winged V-2 ideas were just that, ideas without any real development heft behind them. This didn't stop Von Braun from claiming the were real projects when captured by the Americans as at that point he was trying hard to pivot away from weapons development and having a manned space program to talk about helped make that case - but the reality was these were paper designs with no real development work behind them. Moreover, they were just bad ideas that couldn't have worked for myriad reasons. The payload wouldn't have been worth the effort and the idea of a pilot ditching from a ballistic missile for pick up in the ocean is silly even before you consider that the Germans lacked naval resources to support the recovery effort.

The V-2 had major teething problems as it did break up during flight due to aerodynamic forces. It wasn't really heating that caused the problems, it was more that the Germans did not really understand hyper- or supersonic aerodynamics and the structural loads imposed by flight in that regime. They did put reinforcing bands on the rockets which mostly solved the issue but they never really understood the full problem. Similarly, while the Germans did introduce some swept-wing designs, they more or less wound up in that solution space by accident and trial and error as again, they didn't really have a theoretical underpinning for transonic (and beyond) aerodynamics. That they did have some swept wing designs made them seem much further ahead in high-speed flight research than they actually were.

Another of the V-2's many problems were with guidance. They had a couple of approaches, one was a primitive inertia-based scheme and another (more successful) scheme was radio guidance. Neither of these schemes ever allowed the weapon anything close to precision; the best they could muster was being able to hit cities rather than hitting specific targets within cities. Coupled with a tiny (by ICBM standards) payload, this meant they couldn't do much damage. However, they were able to build enough rockets that they could have caused considerable moral and industrial damage on Britain if they had not been undermined by British intelligence. The British successfully fed inaccurate after-action reports to the Germans which caused the Germans to considerably over-correct their missiles trajectories which meant most of the launches wound up in relatively unpopulated/non-industrial areas. Absent that effort, the V-2 might have had an appreciable effect on Britain but even then, it would have been lost in the noise of the overall damage caused by the war.

Major production was not set up at Peenemunde because of its vulnerability to Allied air attacks. In fact the facilities were raided which killed a lot of prominent German engineers and scientists and did significant damage to the grounds. This prompted the Germans to give up any thoughts of building out production facilities in the area. They instead chose to build their major production lines inland in fortified underground bunker facilities.

As for SS involvement - that was almost entirely due to Himmler's insistence. Himmler was jealous of anyone gathering power and as the V-2 project rose in prominence in the overall German war effort, Himmler made a concerted effort to gain control over the project which culminated in the SS taking over responsibility for production through the use of slave labor.

And as you point out, you have to be extremely skeptical of the memoirs of the various German figures as they are extremely self-aggrandizing and written in large part to white-wash their involvement in wartime atrocities. Talking up potential civilian uses of the V-2 research fits squarely in that mold.
 
The Delta IV Medium is now retired. There are only four or five launches of the Delta IV Heavy left and the factory that produces them for ULA has begun transitioning over to the new Vulcan rocket.
 
for the people who've seen the movie Interstellar I have a question

Spoiler :
In the opening of the movie the little girl Murph says she figured out what her ghost was telling her, "stay". Later in the movie when Coop is trying to send her a message he's shouting "stay" to his own character. Why? Didn't he have to go on the voyage to the black hole to discover the secrets of gravity thereby allowing humanity to leave the Earth?
 
Because in that moment he realized:
Spoiler :
He was never going to see his daughter again and that was due to the fact that he left Earth. In that moment he wanted nothing more than to have lived out his life with his daughter rather than leaving her behind on a dying planet. It wasn't a rational thought, it was purely emotional.
