Real-time Terrain Relative Navigation Test Results from a Relevant Environment for Mars Landing

, 2015
Terrain Relative Navigation (TRN) is an on-board GN&C function that generates a position estimate of a spacecraft relative to a map of a planetary surface. When coupled with a divert, the position estimate enables access to more challenging landing sites

A new method for landing on Mars

Acta Astronautica, 2002
Abstract Up to now, the only means to land payloads on Mars have involved a heavy, complicated, expensive retro-rocket landing system. Another method to land payloads is to use a novel solar heated hot-air balloon, or Solar Montgolfiere, which looks promising to replace the retro-rocket landing system, while increasing usable landed payload.

Europe to land on Mars

Engineering & Technology, 2014
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.

Landing on the Moon, Venus, and Mars

2011
The Soviets reached the zenith of their success at the Moon with robotic missions in 1970 and 1971. In September 1970 the Luna 16 mission successfully returned a sample of the Moon to Earth; an impressive achievement still unmatched by the US. In November the Luna 17 mission successfully deployed the first robotic rover on the Moon, Lunokhod 1; another

Selection of the Mars Science Laboratory Landing Site

Space Science Reviews, 2012
The 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.

Fuel-Optimal Guidance for End-to-End Human-Mars Entry, Powered-Descent, and Landing Mission

IEEE Transactions on Aerospace and Electronic Systems, 2020
This article investigates the fuel-optimal guidance problem of the end-to-end human-Mars entry, powered-descent, and landing (EDL) mission. It applies a unified modeling scheme and develops a computationally efficient new optimization algorithm to solve ...

Mid Lift-to-Drag Rigid Vehicle 6-DoF Performance for Human Mars Entry, Descent, and Landing: A Fractional Polynomial Powered Descent Guidance Approach

AIAA Scitech 2020 Forum, 2020
Defining a feasible vehicle design and mission architecture capable of reliably delivering a payload of 20 metric tons (mt) or more is a great challenge for landing humans on Mars.
