Expert speaks ahead of Nasa Mars landing

The video discusses a Mars mission aimed at finding evidence of past life by landing in Jezero crater. It highlights the challenges of landing on Mars, including the descent process and environmental factors. The rover is expected to last beyond its planned lifespan, collecting data and conducting experiments, including flying a helicopter in Mars' thin atmosphere. The mission will send back high-definition images and store samples for future analysis.
