Yes there are scientists and engineers and astronomers amongst the Destiny crew. Most of them will be dead in 50 years or less just as a natural consequence of ageing, if not falling victim to the elements.
For at least several decades, bare survival is going to be an issue. Surviving winters, building shelters, learning which alien plants are edible and which are poison, learning how best to plant/harvest/rotate crops. Hoping that the harvest produces enough to prevent starvation. In this environment, all those scientific/engineering/astronomy skills will mean nothing. They will be of zero practical value--and aside from maybe someone doing some work in their field in their spare time to keep themselves occupied, any progress in these fields will completely cease.
Fast forward to the first new generation of Novus. They've grown up there. They've never known life anywhere else--not on the technological marvel of Destiny, no real knowledge of the apex of Ancient civilization (Atlantis), even "Earth" is just a word to them. Novus is home. Novus is where they're from, where they grew up, where they grow and buy food. And as the colony continues to eke out its existence, knowledge of deep space astronomy, alien technologies, etc--these are all utterly meaningless to them. Yes they have textbooks. But when you're living as a farmer or a lumberjack or a miller or a cobbler--what possible use could you have for, say, calculus?
Fast forward another few generations and even the Destiny crew are only a memory. By now they're settled and just living out their lives on their homeworld. Maybe they're a mix of agrarian subsistence farming and hunter/gatherer. They don't know much about metallurgy or concrete mixing or any of the things we take for granted. They've never even seen things like that beyond the relics of their forebears. Might as well be a myth. In a world like this, there's still no use for astronomy/alien technologies/engineering. It gets forgotten a bit more.
When knowledge which we consider to be at the forefront of science and advancement is of no use to anyone for decades or centuries, it's lost. It doesn't really matter if it's committed to paper or data disc. If the collective skills and knowledge necessary to use that information are lost, and the ability to use it in any practical way has vanished generations ago, it's going to take many many more generations to re-learn it. And even that will only happen once they've advanced to a point where it's within the realm of conception.
Not as a knock against you, but I would absolutely suggest reading the novel Earth Abides. It's about the survivors of a global epidemic struggling to rebuild after the disaster. At first, the survivor generation does everything they can to pass on their knowledge and history and skills. But it becomes increasingly apparent that the first generation of the new world has little to no use for what their parents are teaching. It just doesn't have any application in their world, and so, all that progress is forgotten. Maybe to be revived later, maybe not. It's a terrific sociological thought experiment, and quite a good book.
