Two-Phase Zero-Effort-Miss/Zero-Effort-Velocity Guidance for Mars Landing
, 2021This paper presents a new two-phase zero-effort-miss/zero-effort-velocity (ZEM/ZEV) feedback guidance strategy for Mars precision landing, which directly accommodates a variety of constraints and r...

Landing a Spacecraft on Mars [PDF]
How much software does it take to land a spacecraft safely on Mars, and how do you make all that code reliable? This column describes such a software development process. The first Web extra at http://mars.jpl.nasa.gov/multimedia/videos/movies/miam20121218/miam20121218-1280.mov is a 60-second video from NASA's Jet Propulsion Laboratory that shows how ...

Error analysis for a Mars landing
Astrodynamics Conference, 1988This paper presents the methodology and preliminary results of a Mars landing error study. Aeromaneuvering was used to reduce the effects of errors. The guidance and navigation techniques used were based on those used for the Space Shuttle. A simulation was built to determine the performance of these techniques in a realistic Mars landing scenario. The
