Anyone saw this rather big scandal about falsified data? www.statnews.com/2018/10/14/harvard-brigham-retractions-stem-cell/It's a pretty big deal and just shows how the funding system twists science. At least in this instance, it's also a good example of the community fixing itself and ethical standards being maintained. I just hope we'll not get to a point where fraudulent data will be disguised so well, that it won't be detected fast enough and will cause damage over years or decades. The potential damage of entire sub fields collapsing like a house of cards would be catastrophic. The funding system that we have these days, which calls for ever faster and more spectacular new discoveries and completely disincentivizes replication and control is a huge problem in that regard though IMO, especially in basic research, where errors (that don't even have to be intentional) may not be visible for quite some time as there are no immediate applications.

I read most of it an failed to found where he got caught. They found evdence of fabricated data? Anyway, this is an interesting case, even if th community is starting to correct itself, it took such a long time a new field of research is born ! And people keep submitting obviously twisted results? Fun stuff

It's not doable. Really not. What a pessimist. It's certainly more doable than landing on the surface, where besides the heat, one has to contend with several atmospheres worth of pressure and acid rain.

I'm not sure that a surface landing would be a good idea. If the probes Russia sent out there didn't last longer than 60minutes, then I can't see how a person could survive it. At least the probes sent to Mars have been able to keep running after all these years. We are collecting more information about Mars and have a better chance of sending a manned mission there. We also seem to have more in common with Mars than Venus. The heat and atmosphere on Venus alone would be too extreme. sci.esa.int/venus-express/34067-venus-vs-earth/

Since we're on the subject of manned exploration of Mars, here's a CG recreation of the proposed 1960s NASA plan of using Apollo/Saturn V tech to do a manned flyby of Venus in '73.

That is probably it then. Did you know they had people send in their names and email addresses to have them aboard that probe? I sent my name in, so that'll be cool knowing it's gonna get roasted by the sun. I also did the same thing with the Orion mission to Mars...at least that one won't get roasted. Eventually, I figure there will be manned space exploration to observe Venus' atmosphere. Honestly, I think missions like that are more important than a lot of other things money is being wasted on. Gaining knowledge is never a waste of time.

It's not doable. Really not. What a pessimist. It's certainly more doable than landing on the surface, where besides the heat, one has to contend with several atmospheres worth of pressure and acid rain. "Pessimist"? <cough...> The magnitude of challenge to move a X tonnes payload from Earth and insert it into orbit around Venus is about the same as for Mars. It's almost the same Delta-V for instance. Time may be a couple of months shorter to Venus, but I don't see that will make much difference. - Then there are a few things different: You can't go down to the surface on Venus. You'll never get up again. You can't decide or hold geographic position on Venus. The winds are 220-320 Mph at the altitude one would be aiming at, 55km. The only materials available to build or sustain the "base" is Carbon Dioxide and Sulphuric Acid. Everything else must be brought from Earth. The difficulty in "landing" lies mainly in rapidly and successfully deploying your balloon, before you fall too deep. I'm not optimistic about this, no. Going back up, should in my estimate prove very difficult. This is where I'm puzzled by that animation. Because getting up to orbit again should be akin to getting up into orbit from the Earth's surface. Gravity is close to the same, and while it is slightly less, Venus' atmosphere extends farther out, meaning you have more drag to battle and need to reach a higher orbit. Also, remember that you don't decide your position (or your original vector). If you're way off from the equator, it's going to cost you more Delta-V to get to the docking point. So basically, I don't understand why we won't need something like the Falcon 9 to get back up? That's 500-550 metric tonnes. You're going to have a balloon carrying that? For reference, Hindenburg weighed in at 240 tonnes. You're going to need a balloon that's 5 times as big as that (Hindenburg could load about 100 tonnes) (correction, CO 2 is denser than Nitrogen so will supply more buoyancy, but still, and 55 km correspond to about 5000m on Earth so you'll need more buoyancy anyway) . I won't even guess what that contraption might weigh, but you still need to brake that giant meteor in Venus' atmosphere, suspend it in enormous parachutes, while you deploy the leviathan balloon. So while we're talking about a 40 t payload to Mars, we're coming up to a 700 t payload to Venus? What's the propellant mass needed to bring that to Venus? ...So I'm a pessimist? Well, in that case I need to know more about that miraculous animated ascent vehicle, how much it weighs, and why it will reach a 300 km orbit again. Mars has a different challenge. It's difficult to land, because of the (essentially) lack of atmosphere. Still, going both down and up seem to me a lesser challenge than just going up on Venus. Also, you don't need to go down with the fuel. You can make the ascent fuel on Mars. You can preposition equipment that takes care of that detail, and many other. Because, remember, you can land where you want and things stay put. Also: Manned expeditions to other planets is such a big challenge that it's necessary to take many small steps. We need to develop the technology, tools and methods over time. So we first need to go back to the Moon. Mars is then a followup to the Moon. Same kind of challenge, just bigger and farther away. Venus? A crazy balloon deployment that has to work perfectly the first time? And while we're at it, what's the longest time we have ever been able to keep a balloon flying here on Earth? I'm not disputing that floating vessels must be the way to go to Venus. Just don't give me any crap about how it's such a more reasonable proposition than Mars. EDit: P.S. the other animation concerns a "flyby". There's a huge difference between doing a flyby and "travelling to". But I still can't understand how the poor astronauts would survive more than a year in that little Apollo ship.

Pickles may help with social anxietyThis may explain some of the differences between Europeans and Americans. We eat a lot of pickles. Almost every burger comes with a pickle, for example. While Europeans do eat pickles, I haven't seen them eat as many or as often as Americans do. #ilovepseudoiscience
