Obviously I researched before I commented. I'm not going to call someone out on something I'm not confident on.

The primary source of radio static is artificial (other electronic devices in the environment, as well as heat from the radio itself). The natural component (atmospheric noise) is mostly a result of lightning. The cosmic component is mostly solar activity with a small component coming from the Galactic core, the Cosmic Microwave Background and other extragalactic events (Source 1, Source 2).

While Jupiter does emit some radiation that's useful in radio astronomy, it makes up a negligible component of the environmental noise that the average radio picks up.

You should follow your own advice and use Google before you spread misinformation.

Actually the so called knockoff came straight from the original NASA files that were in the National Library. Since NASA is a public domain organisation, the files were not flagged as confidential. Russians were able to take copies of those files pretty easily. When NASA found out what was going on they made slight changes to the original files, e.g. the tiles that protect the vehicle during re-entry were left with with the early versions. You can find more about this on the internet but here's a link https://www.nbcnews.com/id/wbna18686550

They ran out of money, unfortunately. Energia and their shuttles, Buran and Pichka were very ambitious, and very expensive. The Buran was launched unmanned into space, and orbited the Earth twice, and made a fully automated landing. A successful first flight by any measure. Sadly, the collapse of the Soviet Union meant that the budgets for these programs weren't maintainable financially. The USSR had some very good aerospace engineers. It's a shame, really. You should read all the links others have posted on this thread.

It is fairly widely accepted to have been the safer of the two shuttle designs. The issues that the US shuttles ran into were addressed in the design of the Buran. The Buran didn't have debris from its own launch vehicle raining down on top of it for example.

The only reason they discontinued the program was because of the expense, and because they didn't really have a use for it. It was the smart call, though the smarter call would have been to never make it in the first place. The Shuttle probably set US space exploration back by decades, marvel (albeit flawed) of engineering that it was.
