tater Posted November 16, 2023 Author Share Posted November 16, 2023 (edited) "Hopping" rovers for the Moon would actually be really awesome.

SunlitZelkova Posted November 18, 2023 Share Posted November 18, 2023 TASS reports Sarmat has gone on experimental combat duty. Interestingly, this has a historical precedent. According to Steven J. Zaloga, during the height of the Cuban Missile Crisis, one of the R-9A ICBMs was put on launch alert at the test stand at Baikonur, despite being a prototype.

kerbiloid Posted November 18, 2023 Share Posted November 18, 2023 If (just a theory) it's a localized R-36M ancestor with upgraded intestines, then whyn't? The R-36M booster itself looks rather canonical, but the head may vary. Quote Link to comment Share on other sites More sharing options...

Pretty much all Russian rocketry since the fall of the Soviet Union are "localized" Soviet designs, in some cases with new stickers. As far as ICBMs go, this isn’t exclusive to Russia though. The US still uses the Minuteman III, the shiny new Peacekeeper was shelved. Sentinel is on track to rival the SLS in terms of pork. Scientific American just released an article the other day calling for its cancellation. Part of the problem with getting a replacement for Soyuz or Proton is that those rockets just work. They have run into the same problem as the Space Shuttle- it works good enough for what we want to do, so there is no money to go around for something new (whether that be Angara, Soyuz-5, or Shuttle-derived SHLV). Unlike the Space Shuttle, Soyuz may continue to fly indefinitely, so it may be awhile for its successor succeeds. Angara on the other hand has a better chance because Proton production has ended, IIRC. Quote Link to comment Share on other sites More sharing options...

There's a crucial difference: it's difficult to ask for money to go around for something new. Preferably a large sum spread over several years that other projects cannot dip their paws into. Starting this October there is finally a push to give Roscosmos their own National Project with ROSS constituting one of the Federal Projects therein. This might or might not at least somewhat stabilize and organize the goings-on in Roscosmos... or finish it off. I've had to dig into the guts of two such projects at work and the people we've talked to weren't particularly upbeat about their KPIs.

Then baked into a globe-shaped loaf floating in a zero G convection oven. The air currents in the oven, under raspberry pi control, keeping the loaf from touching the walls. The resultant loaf could be quite useful in physics experiments as a stand-in for a spherical cow until we master how to make those.

It could get quite heated with so many cooks in the Orbital Reef Kitchen! https://en.wikipedia.org/wiki/Kolobok Spoiler The classic Russian legend tells about Kolobok ("The Round-Sided One"), who was a sapient, human-faced, spherical bread, made out of remains of grain in the stock, by the couple of elders. It can't be just a coincidence that Kolobok has a hydrostatic equilibrium shape. Obviously, it was baked in zero-g, so the oven, used by them, was somehow related to the further orbital station experiments. If send Kolobok enough far, to the hypothetical Oort cloud, it could be a planet. Quote Link to comment Share on other sites More sharing options...

So is it safe to say one’s economic system actually has no bearing on whether production goofs like this happen or not? Because when I read about the history of the Soviet program, accidents like these are usually attributed to issues inherent to the Soviet system. China eliminated these when it had a big campaign in the 1980s and 1990s to adopt Japanese work ethic, but did Russia not go through anything like this despite a change in economic thinking?

Quote Carson said he pressed superiors for better safety measures but was ignored. He recalled stepping into the interior of a rocket under construction in 2021 on his first day as a supervisor. Another manager, working 20 feet above him, carelessly dropped a nearly 100-pound hoist, barely missing Carson. “That’s like a firing offense at other places, but not at SpaceX,” Carson said. “They needed bodies, and Elon needed stuff done.” https://www.reuters.com/investigates/special-report/spacex-musk-safety/ Quote Link to comment Share on other sites More sharing options...
