SpaceX doesn't have unlimited tax dollars to work with so they have to save where they can, even at their cost the fairing is a few mil. Compared to that the cost of a parachute and boat is negligible.

Pathetic. Let me know when the fairing can land under rocket power.

There's no way the fairing costs that much. That has to be a lie by spacex.

>> No.9780995

>>9780984
Nope, they cost 10% of the whole rocket (for both halves). Or, about $6,000,000. Fairings are complex, large composite structures. They aren't cheap!

Probably because they came in from other aerospace companies. All of the interns and first-job SpaceX employees either have extremely specific skills, or super exemplary academic records, AND detailed, impressive hobby/etc work.

tbf lots of SpaceX employees just stick around for a couple years, get the neat SpaceX entry to stick on their CV's, and then move onto a less stressful aerospace job somewhere

true. I bet they'll nail it in a couple months. But the first fairing reflight might take a while. Wouldn't be surprised if they wait for a starlink launch to debut the reused fairings
