insert_name Posted November 8, 2023 Share Posted November 8, 2023 SpaceX got another X-37b launch, this time on falcon heavy, wonder why they are using it instead of regular falcon https://spacenews.com/u-s-air-force-x-37b-spaceplane-to-launch-on-a-spacex-falcon-heavy-rocket/ Quote Link to comment Share on other sites More sharing options...

That would be interesting 5 minutes ago, CatastrophicFailure said: That’s an awful lot of extra delta-V there… could an X-37 survive reentry from medium/high orbit? If not, they could mildly aero brake to a get lower apoapsis, then adjust from there to a gentler reentry perhaps Quote Link to comment Share on other sites More sharing options...

I think, by deduction, they must be at least testing this capability. Perhaps they are testing out new thermal systems? Quote Link to comment Share on other sites More sharing options...
PakledHostage Posted November 9, 2023 Share Posted November 9, 2023 A little bit off topic, but I thought I would share that I am writing this post from 36000 feet above the North Atlantic, well out of range of terrestrial internet. I suppose I have SpaceX's Starlink to thank for the opportunity? Quote Link to comment Share on other sites More sharing options...

Spaceception Posted November 9, 2023 Share Posted November 9, 2023 Short of an actual license, isn't this one of the best indicators of an upcoming launch? Adding onto all the other notices we've seen like road closures, and maritime warnings over the Gulf and Hawaii, everything is starting to line up. They have to be hearing good things internally from the FWS that they're about to wrap up. Quote Link to comment Share on other sites More sharing options...

I hope it launches on the 15th, that's probably the only day I have a chance of seeing it live, since I either have work or school most of the week. Next launch attempt I'm hoping for is during my lunch break Quote Link to comment Share on other sites More sharing options...

" as i understand it the only agency that still hasn't signed off is fish and game. idk what kind of game you're going after if you need starship to take it out. but that sure would be an interesting hunt. wonder what the bag limit is for cthulhu. 1 hour ago, magnemoe said: How about the module SpaceX blew up using FTS charges, it would newer launch, it was just an test object. i guess it would fall under commercial demolitions regulations.

JoeSchmuckatelli Posted November 10, 2023 Share Posted November 10, 2023 At moderators - my posting from an Alt is at the request of @Dakota - please excuse the violation of forum rules. We're trying a workaround to get me access to Sci & Space again. Obviously, these posts are off topic for my favorite thread. I'd ask them to be deleted once this test is complete. Thanks!

FWS was apparently worried about some sort of shark being killed by SH, SpaceX asked them how many such sharks in the different regions of the Gulf, FWS said they couldn't tell them because the shark locations are secret to avoid illegal fishing (shark fin), SpaceX apparently asked how they could calculate the probability of randomly hitting a shark without that information... took a while to work out. Probability is ≈0, as one would expect (small shark, big ocean, tiny time interval of risk, etc). Quote Link to comment Share on other sites More sharing options...

When talking commercial airplanes, probabilities of 10^-6 are considered significant. Of course, there are a lot more commercial airplane flights every day than space launches.

Of course, there are a lot more commercial airplane flights every day than space launches. Yes, and those also tend to result in the possibility of multiple human deaths vs the incredibly unlikely chance a certain type of shark (likely a singleton) happens to be in a few square meters of water, near the surface, during the few seconds of SH impact. In the case of the shark, it's important to realize they can't have a zero probability of harm standard, or they'd have to disallow all watercraft. Boats/ships can and do collide with sea life, and the gulf is full of watercraft. Also, every other rocket except F9 drops stages in the ocean as SOP.
