This article just links to https://twitter.com/elonmusk/status/1285338582849208320 and adds a bit more context, if you don't want to blindly accept the Verizon GDPR wall.

I am just amazed that NASA turned around a shuttle in 54 days, I don't even recall it. Apparently these were the first two missions flown[0]. However I also read almost suffered Columbia's fate on one of its flight due to a large loss of tiles

This website is not trustworthy and doesn't respect GDPR as it redirects to https://guce.advertising.com/collectIdentifiers?sessionId Engadget, stop this nonsense and change the responsibilities of the team who decided to put this into production.

I'm not sure why you were downvoted, I hate sites where the only option to "do you want to be tracked?" is "yes" too.

There's always the ctrl-w option. It seems better that you have to consent rather than them just assuming you consent since you opened a link.

That is usually what I resort to.

Yes, but one of the two is completely illegal, and the other is slightly illegal.

So are the fairings passively falling, or are they guided to the ships in some way? Ships are very slow compared to even a parachuting object from the sky.

They use steerable parafoils.

Do you know how the steering is being done? Is it controlled from a computer on the fairing or is it remotely guided?

I apologize for not being able to find a cite, but my recollection is it's automated, targeting a set of GPS coordinates.

IIRC it's automated GPS to a staging area and the local ship takes over control when it comes within radio range.

"Elon Musk, SpaceX’s founder and CEO, told reporters last year that the fairing costs around $6 million." Pretty good if they can recover them and refurbish them. Could save a few million dollars per launch, even more if they can be re-used more than once.

Perhaps even more importantly, they are a big bottleneck on their flight rate. They require a massive autoclave (for curing the composites), and it wouldn't be practical to scale up their production significantly.

Even if it didn't save them a penny, my guess is it would still be a priority.

They considered doing that to reuse the Saturn V with a giant helicopter with rockets at the end of each propeller. It didnt go anywhere. Though people have been using air capture for more reasonable use cases, and rocket lab is going to be air capturing their electron rockets.

I haven’t heard about this giant helicopter idea before. Here’s an article I found about it: https://www.thespacereview.com/article/1045/1

Very cool article. The Hiller Air & Space museum mentioned in the piece is well worth visiting if one happens to be in the Bay Area.

Dumb question I'm sure has been asked... we've been throwing stuff into the sea for awhile then going and picking it up later as it's bobbing gently in the waves. Why not just have some inflatable buoys that deploy in the water and have it float? Catching it seems pretty difficult, albeit pretty sweet.
