Whatever happened to aerospike rocket engines?
Every time they get built, they never get launched. NASA looked into them this century - as in the 2000s+ for one of their projects. ARCAspace says they've built one, had a series of videos leading up to the test/launch and then...took a break for a month, returned, and didn't act like anything happened, going back to their conventional nozzle rocket for a spell.

Maybe they're cursed by the ghost of Proxmire. They also seem complex; basically ten or so smaller thrusters in a parallel array - maybe the TurboPump problems come back in a sort of spectre? In any case, I hope they actually fly one day.
