The English word 'rocket' can refer to a spacecraft, a missile, or a firework. In Japanese, the most common equivalent is ロケット (roketto), a loanword from English. However, depending on the context, other words like 宇宙船 (uchūsen) for 'spaceship' or 花火 (hanabi) for 'firework' may be more appropriate.
