Re: In Plane Sight.

Indeed, it would be an engineering miracle to build a plane's wings so that they would perform as a 100% fuel-tight container, and to remain this way for the +20 years of useful life of an airplane, while subject to flexing, vibrations, pressure changes, metal fatigue and varied mechanical stress fo...

Re: Chemtrails: chemical weapon or psychological weapon?

I must say that I was quite skeptic about the chemtrail thing, but I've recently stumbled upon some news in mainstream media, where farmers from the Spanish region of Murcia say that some 'anti-rain' flights are taking place in their area, and demand further investigation. They have some pretty soli...

Re: Elon Musk, SpaceX and PayPal

Utterly disheartening... At least, NASA's fakes were way classier. This is not serious. Looks rather like a cheap "reality" TV show. A highly emotional production tailored to the taste of the milennial generation...

That was in 1989, so it shouldn't be that difficult nowadays.

Re: Stars/no stars - and other space oddities

So, it seems that now there is a Christmas campaign with pizza supplies and the like. Anyway, to keep centered on the 'stars' issue, shouldn't they appear in this nice shot? https://twitter.com/NASA/status/935992519954960385/photo/1 As for what NotRappaport noted, I guess that you can achieve the sa...

Re: Stars/no stars - and other space oddities

Anyway, it's quite strange that down on Earth seems to be no problem in photographing scenes where stars are quite apparent, like this 360º shoot in Google Maps. I can understand that a photo in daylight requires a small aperture and hence small and dim objects would not appear. But how about 'night...

Re: Amateur Astronomy: What can we see?

Well, if the japanese are up to things like this one... It's just a matter of scaling. Ijxe9qghRAU EDIT: In fact this was not an hologram, just a projection in transparnent screen. However, I did a bit more of research on this topic, and it seems that already in 1969 it was possible to project holog...

Re: Does Rocketry Work beyond Earth's atmosphere?

Anyway, I think it could be much, much simpler than that. Forget about Joule-Thomson, Newton's third law & so on. It's more than enough with the 2nd law. If we want to accelerate a solid body, we must apply a force upon it. Period. In a rocket, the only places where we can do that are the nozzles, a...

Re: Does Rocketry Work beyond Earth's atmosphere?

Anyway, I'm inclined to think that LEO sats (but no more than that) could be launched by just ballistic rockets, without need for them to work in the vacuum. I've been googling how it all began, with the Sputnik. If we have to believe Wikipedia, it was launched by a R-7 rocket , which was a missile ...

Re: Fakery in Orbit: THE I$$

Interesting... It also seems awkward that back in 1969 they managed to transmit live from the Moon, but they had lost the know-how by 1998; maybe the Apollo engineers had retired by then. But anyway, there was no problem in taking a bulky iMax camera in a high risk spacewalk for fixing the Hubble te...

Re: NASA'S FLAT EARTH DBA STRATEGY

Anyway, I've found that some of the objections in the 'flat earth' videos are quite real (not that I'm a 'flat-earther', of course). For example, the one I'm bringing points to a quite evident flaw in that amazing HD time-lapse shoot in 4K from "the Thing". Namely, the long lasting lightnings and st...

Re: Fakery in Orbit: THE I$$

A possible hypothesis: Could it be something like https://en.wikipedia.org/wiki/Project_Echo? I'm not sure it could be put in orbit with just a ballistic rocket, but let's suppose it can be sent as a very lightweight deflated balloon which once in orbit would inflate to a very BIG size. That would e...

Re: Does Rocketry Work beyond Earth's atmosphere?

Out of my interest and recent skepticism about space travel, I've recently followed "live" in YT two launches: the OA-8 resupply vehicle (https://www.youtube.com/watch?v=JM5POTQoSXY) and today the JPSS-1 NOAA observation satellite (https://www.youtube.com/watch?v=5wUrNNnkR5Y). Bad luck, as both laun...

Re: Why these two video from the same event are so different

Well, maybe they did like with Star Wars, a digitally remastered version.
Also, I think it was noted the really funny orbit that Gemini is following, very apparent in the accelerated version.
