<prompt> I-Argon isetshenziswa njengophethiloli ekuthuthukiseni i-Variable Specific Impulse Magnetoplasma Rocket VASIMR. Igesi ye-argon ecindezelwe ivunyelwe ukuthi ikhule, ukupholisa amakhanda abafuna ezinye izinhlobo ze-AIM-9 Sidewinder missile nezinye izinhlamvu ezisebenzisa amakhanda okufuna okupholile. Igesi igcinwa ngaphansi kwengcindezi ephezulu. I-Argon-39, enesikhathi sokuphila seminyaka engama-269, isetshenziselwe izinhlelo eziningi, ikakhulukazi i-ice core ne-ground water dating. Futhi, i-potassium xenon ne-argon yokuqomisana ehlobene nayo isetshenziselwa ukuqomisana ne-metamorphic sedimentary, igneous rocks, futhi i-Argon yengezwe ohlwini lwe-World Anti-Doping Agency ngo-2014, yize i-Argon ayisetshenziswa njenge-agent enokwethenjelwa yokulinganisa ukuhlukumeza.  <response>: Iminyaka engu - 269
