That entry, descent and landing is a huge challenge for us for Mars.”NASA has landed several unmanned exploratory vehicles on Mars in the past. The Curiosity rover, which landed on Marsh in August 2012 and will soon be celebrating its five-year anniversary exploring the planet, cost around $2.5 billion.
