SpaceCapsule
Spacecapsules,alsoknownasspacecraftcapsulesorsimplycapsules,aresmall,crewedvehiclesdesignedforspaceexploration.Thesecapsulesaretypicallyusedfortransportingastronautstoandfromspace,aswellasforcarryingsuppliesandequipmenttoandfromspacestations.
Thedevelopmentofspacecapsulesbeganinthemid-20thcentury,duringtheSpaceRacebetweentheUnitedStatesandtheSovietUnion.Thefirstsuccessfulspacecapsule,Vostok1,waslaunchedbytheSovietUnionin1961withYuriGagarin,becomingthefirsthumantoorbitEarth.Thissignificantachievementmarkedthebeginningofhumanspaceexploration.
