Russian schoolchildren in Year 1 typically start school at the age of six or seven. This is because the mandatory school age in Russia is 6 years old, and most children begin their education in Year 1.

As for the second part of your question, it seems like there might be a typo or misunderstanding. "How many mars are there?" could be interpreted in different ways. If you are asking about the number of planets in our solar system, there is one Mars. It is the fourth planet from the Sun. However, if you are asking about the number of objects named "Mars" (like landers, rovers, or missions), there have been multiple missions to Mars, including rovers like Sojourner, Spirit, Opportunity, Curiosity, and Perseverance, among others.

If you have a different interpretation in mind, please provide more context, and I'll do my best to address your question.
