Beccab Posted December 30, 2022 Share Posted December 30, 2022 (edited) 60th and last F9 launch of the year has been completed successfully Edited December 30, 2022 by Beccab Quote Link to comment Share on other sites More sharing options...
StrandedonEarth Posted January 1, 2023 Share Posted January 1, 2023 (edited) Just a quick 2022 Falcon 9 recap; I had to tabulate it myself since I didn't quickly find the info I was looking for. So I condensed a list from the wiki page, and this is what I came up with (boosters and flight numbers). For a wonder it added up to 60 missions, so it should be right. Spoiler 1062 4 5 6 7 8 9 10 11 1058 10 11 12 13 14 15 1060 10 11 12 13 14 1052 3 4 5 6 7 1071 1 2 3 4 5 6 1061 6 7 8 9 10 11 1063 4 5 6 7 8 1051 12 13 14* 1067 4 5 6 7 8 1073 1 2 3 4 5 1069 2 3 4 1077 1 1049 11* 1076 1 *Expended In 2022, the sixty F9 flights were made by 14 boosters. 4 boosters made their maiden flights; two of those only flew once (the other two combined for 11 flights). B1049 also only made one flight, its 11th and final flight. So that makes it 3 boosters that only flew once. 2 boosters were intentionally expended (B1049 and B1051 on its third flight of the year) after 25 career flights between them (Rest in Pieces, they served well). All others were successfully recovered 1 booster, 1062, made 8 flights (the first and second-last flights of the year), 3 boosters made 6 flights each, and 5 boosters made 5 flights each. 2 boosters made 3 flights each. That saved a metric crapton of manufacturing capacity! Edited January 1, 2023 by StrandedonEarth Quote Link to comment Share on other sites More sharing options...
JoeSchmuckatelli Posted January 1, 2023 Share Posted January 1, 2023 Have we ever seen a "cost per unit" on engines? If so that could give a guesstimate of how much they're saving over say something like ULA which flies expendable. Quote Link to comment Share on other sites More sharing options...

Probably very hard to calculate, you need an decent launch numbers for reuse to even make sense. You also has production limits who help reuse, but just looking at an cost breakdown, cost of reuse is cost of recovery and cost of refurbish who is obviously much cheaper than building everything each time. The launch is the same cost anyway but you save plenty on weekly launches as lots of the cost is fixed. SpaceX has the benefit of being their own customer because of starlink.

There's always one lagging behind the others usually, they're only brought down by gravity so it depends from the angle the rocket has when the legs are released. First successful launch/landing of 2022, second stage ignition number 2 is in 45 minutes followed by rideshare sats deployment Quote Link to comment Share on other sites More sharing options...

Correct - these tiny arms next to the main folding mechanism are what pushes it, then gravity does the rest Quote Link to comment Share on other sites More sharing options...

Beccab Posted January 5, 2023 Share Posted January 5, 2023 The full stack WDR should now be the penultimate test before launch, followed by 33 engine SF (if successful) Quote Link to comment Share on other sites More sharing options...

JoeSchmuckatelli Posted January 6, 2023 Share Posted January 6, 2023 How important is a 33 engine static fire test? Presuming there is a risk of damage to the table... would it be better to just go for a launch and capture data from that (or is it pretty much necessary to static-fire test the whole shebang before attempting a launch)?

That’s what they did with N-1, and we all know how that went… Quote Link to comment Share on other sites More sharing options...
