According to Jainism, ordinary human beings do not normally go to other planets by rockets or spacecrafts in the scriptural sense.

Key points:

• Jainism speaks mainly about the soul’s rebirth in different realms based on karma.
• Travel by physical vehicles like rockets is a modern idea, not something explained as a spiritual doctrine in Jain texts.
• Jain cosmology includes many realms and worlds, but a soul reaches them through karma and rebirth, not by technological travel.
• So, from the Jain viewpoint, space travel may be possible as a worldly scientific activity, but it is not a part of Jain spiritual teaching and does not change karma by itself.

In short: Jainism does not teach that rockets or spacecraft are the way to go to other planets in the spiritual or karmic sense.
