engineering challenges of sending humans to the planet Mars
You can ask any question (Industry, Lessons, Analysis etc..) to aerospace engineers.
Question: Discuss the engineering challenges of sending humans to the planet Mars by the year 2030. You should address the following specific questions in your answer: (a) How long would it take (in days) to travel from Earth to Mars? What stops us from getting there any quicker?
(b) What would a spacecraft designed to enter the Martian atmosphere and land on the planet surface look like? What would it be made of? Is landing on the Martian surface (from orbit) easier or harder than landing a spacecraft (from orbit) on Earth?
(c) How much would a one-way ticket from Earth to Mars cost?
(d) Is it possible to design an aircraft to fly in the Martian atmosphere? What would such an aircraft look like?
