The user asks: "When did Elon Musk go to Mars? (Answer in en. Please keep your response under 500 characters)". We need to answer in English. But we need to respond to the factual question: "When did Elon Musk go to Mars?" The correct answer is that Elon Musk has not actually traveled to Mars (as of 2025). He is a proponent and leader of SpaceX and has stated intentions but hasn't physically gone to Mars.
Thus answer: He hasn't gone to Mars yet. No specific date. Provide answer under 500 characters.
The question is likely a test of factual knowledge: It's not that he hasn't gone; if someone says he is planning but hasn't. So answer: He hasn't gone. Provide short answer.
We can answer concisely: As of now , Elon Musk hasn't been to Mars; his plan is to develop SpaceX's Starship for future crewed missions, but no date is set.
Answer in English. Keep under 500 characters.
Thus output: "He hasn't. As of 2025, Musk hasn't traveled to Mars; his SpaceX plans to develop Starship for future crewed missions, but no mission with Musk onboard has occurred." That is well under 500 characters.
Make sure answer is under 500 characters. Provide a simple answer.
Proceed to final.
