Bow wave and stern wave. https://van.physics.illinois.edu/qa/listing.php?id=1047&t=double-sonic-booms! Any abrupt change in cross-sectional area actually creates a wave (and the associated wave drag), which is where "area ruling" comes from. But the bow wave where area goes from nothing to something) and the stern wave (where area goes from something to nothing) are usually the biggest. They often tend to merge into a single wave at some distance from the source, but depending on their speed, the shape of the object, the distance of the observer, etc., they can be heard as two separate waves. The Space Shuttle was often heard as a "double boom" during re-entry. Edited July 29, 2019 by mikegarrison Quote Link to comment Share on other sites More sharing options...

Actually, that would be kinda neat if, on the boosters, capsules, and Starships, they painted a marker for every mission flown. "'Booster ace' 'Don't Read the Instructions' has made its 25th landing today. Leading the scoreboards is 'I Left Something Behind' at 32 successful missions." The survival rates are probably better than those of WWI aces... 3 hours ago, tater said: Maybe they paint one on the side for every worker blown into the gulf of Mexico by the exhaust?

It might be an excellent way of shaping public opinion on how safe rockets are, especially in the point to point market. Quote Link to comment Share on other sites More sharing options...
Wjolcz Posted July 29, 2019 Share Posted July 29, 2019 (edited) They already paint those on Dragons, it seems. Probably don't care about boosters as much since they are meant to have finite launches (the goal is like 25-ish right now?). Edit: maybe also because the stickers would end up under soot, anyway.

Sticker on, launch, remove sticker, job done . youd have continually darkening silhouettes then the more launches they survive Quote Link to comment Share on other sites More sharing options...

Jaff Posted July 30, 2019 Share Posted July 30, 2019 Whilst it is out of the norm these days for space x to throw something in the drink (intentionally - I’m looking at you heavy cores!) we have to consider this booster has been used twice already so has probably already paid for itself as far as space x are concerned. its easy to forget that everyone else throws them away after 1 use, this one is going after 3. Which is worth noting that customers are also happier these days to pay for a used booster. It wasn’t that long ago people were convinced customers wouldn’t pay for a used booster Quote Link to comment Share on other sites More sharing options...

Yeah, it will rest in a good company. Who knows? Maybe couple of hundreds of years in the future, underwater archeologists will comb seafloor in search of early space age artifacts? We've already fished up Saturn's first stage (remains of) and placed engines in museum. Quote Link to comment Share on other sites More sharing options...

I guess, much sooner, on the next upgrade of national anti-sub sonar/magnetometer networks, lol. They will map all metal scrap.
