Rocket Report: The final space shuttle stack; SpaceX may extend booster lifetimes

Welcome to Edition 6.22 of the Rocket Report! We're nearing the end of 2023, and it's been an incredible year for rocket debuts. Early in the year we saw small lift vehicles from Relativity Space and ABL, and in the spring Japan's H3 and SpaceX's Starship rocket. There's one big one left: United Launch Alliance's Vulcan booster. That will be a nice stocking stuffer to end the year on Christmas Eve.

As always, we welcome reader submissions, and if you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Vega has a missing parts problem. In unhappy news for Italian rocket-maker Avio, two of the four propellant tanks on the fourth stage of the Vega rocket—the upper stage, which is powered by dimethylhydrazine and nitrogen tetroxide fuel—went missing earlier this year. Now, it seems that the propellant tanks have been found. However, Ars reports, the tanks were recovered in a dismal state, crushed alongside metal scraps in a landfill. This is a rather big problem for Avio, as this was to be the final Vega rocket launched, and the production lines are now closed for this hardware.
