Congratulations Mark and Priscilla!

I cannot comment on the content at all because I can't access the submission.

Pages submitted to HN should simply not be behind login walls, which is why I flagged this.

This thread already has multiple references to the fact that you have to log in to see the submitted post. There are many HN users without a FB account. For them, the headline of the submission cannot be verified by clicking on the link.

Although there is a large intersection between the two groups of HN and FB users, you don't have to be signed up with any other webservice in order to use HN. This is not only about FB. As a matter of principle posts to HN should be accessible for all HN users without requiring them to sign up with any other webservice.

However, this is up to PG and the HN community. It would be good if PG provided a guideline whether submissions behind login walls are accepted or not.

Amazing!

The fact that trajectories are being patented at all is what I took away from this. That's astounding in it's ridiculousness. I assumed that was why this was posted.

Your analogy makes no sense, the failed launch has nothing to do with the patent, the patent just stopped an attempt at saving the satellite. So more like the factory caught on fire and no firetrucks could come because a competing factory had patented the route from the firehouse.
