Waypoint-Optimized Zero-Effort-Miss/Zero-Effort-Velocity Feedback Guidance for Mars Landing
, 2013This paper investigates the optimization approach to generate waypoints for the Mars landing problem in the context of employing the zero-effort-miss/zero-effort-velocity feedback guidance algorithm.

Analysis of a terminal landing on Mars
Journal of Spacecraft and Rockets, 1995This study consists of a preliminary performance and sensitivity assessment of trajectory and guidance capabilities of a Mars terminal landing phase. The phase begins with the end of the entry phase, which is at parachute deployment. Therefore, the trajectory investigated in this study starts at parachute deployment and continues through parachute ...

Performance Trades for Mars Pinpoint Landing
2006 IEEE Aerospace Conference, 2006Previous Mars landers have been able to land only within tens to hundreds of km of a target site. Principal sources of uncertainty are approach navigation, atmospheric modeling, and vehicle aerodynamics; additional (lesser) uncertainty sources are map-tie error and wind drift.

What Went Wrong with the Mars Landing?
Science, 2000Speculation regarding the failure of the Mars Polar Lander mission has not included the possibility of a fragile and thermally unstable soil at the landing site [see related News of the Week articles “Yet another loss to the martian gremlin” by Richard Kerr (10 Dec., p.

Toward improved landing precision on Mars
2011 Aerospace Conference, 2011Mars landers to date have flown ballistic entry trajectories with no trajectory control after the final maneuver before entry. 12Improvements in landing accuracies (from ∼150 km from the target for Mars Pathfinder to ∼30–40 km for MER and Phoenix) have been driven by approach navigation improvements.

Balloons for controlled roving/landing on mars
Acta Astronautica, 1999Abstract Until now, the only practical balloon systems proposed to explore the martian atmosphere have been superpressure balloons, which fly at a constant altitude, or short-lived helium balloons, which precariously drag a snake through all types of surface weather, or a day/night combination of the two.

Getting There: Landing an Onion on Mars
2013To try to simplify the ideas in this book it is helpful to visualize this informational ecosystem in layers. To aid in this one might imagine a metaphor to describe the involved dynamic and continuous process. It is somewhat of a two-part metaphor to be specific.

Second generation Mars landed missions
2001 IEEE Aerospace Conference Proceedings (Cat. No.01TH8542), 2002Mars future landed missions include safe, accurate landing of payloads large enough to accomplish a sample return mission or to accommodate both a comprehensive science instrument suite and extensive in situ resource utilization payloads. In addition, the landers may be fixed (immovable) or have sufficient mobility capability to rove multiple ...
