Landing on Mars: Challenges and Triumphs of Reaching the Red Planet
Lesson Express
Q: What are the primary challenges of landing a spacecraft on Mars?
A: The main challenges include the thin atmosphere on Mars, which offers little resistance to slow the spacecraft, and the need to manage heavy payloads, especially with crewed missions. Communication delays between Earth and Mars also complicate landing operations.
Q: How does landing a human crew differ from landing a rover on Mars?
A: Humans are more sensitive to high gravitational forces and require more supplies, such as water, which increases the spacecraft’s weight. Unlike rovers, human missions also require life support and greater safety measures.
Q: What strategies are scientists using to slow a spacecraft for landing on Mars?
A: Scientists use methods like retro propulsion, where thrust is used to counteract gravity, and landing sideways to increase atmospheric drag and slow down the spacecraft more efficiently.
