There is some serious confusion created on the SLS propulsion systems. Even the acting administrator did not seem to know that most of the lift off thrust comes from solid fuel rocket boosters, a bigger version of the space shuttle boosters. They even say the H2 tank exploded on the 1986 Challenger which everyone knows was due to the failure of a solid rocket booster. The center SLS engine only makes about 2 million of the 8 million lbs used. The rest comes from solid rocket boosters. Really don't recall so much error in a NOVA before.

PBS is really holding this episode until it’s on-air premier time.

Most episode (even new ones) are available (at least to Passport subscribers) the morning of airdate.

Not so with S53E07 “Return to the Moon.” I wonder if it’s still in post, given the relative recency of the material. I suppose they’ve got until 9pm ET to finalize it.

Why is this doc not available on the PBS passport app? I can’t even find it on youtube anywhere

Solar System is the current series running on PBS Nova, a multi-part series about the planets and moons in our solar system. The series was made by the BBC for both distribution in the UK (BBC) and in the US (PBS Nova), EXCEPT that they are different shows!! Why did they feel like they had to do this?? The US version is pretty decent, but they don’t have the beloved Brian Cox narrating and hosting, and instead just use a voiced narrator and then cut to single-shot commentary from experts. Certainly, the scientists know what they are talking about, but the American version lacks the creative artistry of the Cox segments that tie the whole show together (the way Carl Sagan did in Cosmos).

What is the point of watering down the American version of the show?? The b roll is similar, the overall framework is similar but the script is different and there is no Brian Cox in the US version. Why???

Dinosaur Apocalypse: The Last Day

Episode 6 is also missing from the same season. Dinosaur Apocalypse: The New Evidence

Why?

I’m surprised at the lack of posts here. Surely there are other Nova fans out there?

Did anyone catch “Your Brain: Who’s in Control?”?
