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.

Hugs and high-fives among mission staff marked the risky but successful landing last week of Curiosity, the newest of the National Aeronautics & Space Administration’s Mars rovers. If all continues to go well, the craft will spend the next two years searching for evidence that the Red Planet has ever been able to support life. As the craft touched down

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

Only one country has so far managed to land objects on Mars successfully - the USA. Not wanting to get left behind, Europe is building its own rover - the ExoMars. Its three prototypes are currently roaming a mock section of Mars built at Airbus's facilities in Stevenage, UK.

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 ...

Simulation and Spacecraft Design: Engineering Mars Landings
Technology and Culture, 2015A key issue in history of technology that has received little attention is the use of simulation in engineering design. This article explores the use of both mechanical and numerical simulation in the design of the Mars atmospheric entry phases of the Viking and Mars Pathfinder missions to argue that engineers used both kinds of simulation to develop ...

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.

Mars Precision Landing Using Guided Parachutes
20th AIAA Aerodynamic Decelerator Systems Technology Conference and Seminar, 2009A method for precision landing of manned spacecraft and cargo modules on Mars using guided parachutes was successfully demonstrated in terrestrial tests. A simulation model was developed based on those tests to explore the full capability of this type of system. The Mars Guided Parachute (MGP) concept of minimizing Mars landing site errors was found to

Selection of the Mars Science Laboratory Landing Site
Space Science Reviews, 2012The selection of Gale crater as the Mars Science Laboratory landing site took over five years, involved broad participation of the science community via five open workshops, and narrowed an initial >50 sites (25 by 20 km) to four finalists (Eberswalde, Gale, Holden and Mawrth) based on science and safety.

Streamlined design approach lands Mars pathfinder
IEEE Software, 1999The author details the design methodology used to develop the flight software architecture for the Mars Pathfinder spacecraft. More generally, he explores design techniques and development approaches for producing high-performance, highly reliable systems faster and less expensively.
