Autonomous Navigation for Mars Exploration

The autonomous navigation technology uses the multiple sensors to percept and estimate the spatial locations of the aerospace prober or the Mars rover and to guide their motions in the orbit or the Mars surface...the application of the autonomous navigation technology for the Mars exploration is presented.

Yardang on Earth and its implications to Mars: A review

Yardangs, as typical aeolian landforms, are extensively identified in arid/hyper-arid areas on Earth and other terrestrial bodies...Under the rules of Earth-based yardang evolution, it is potential to identify the specific level of development and explore the geomorphological processes as well as the climatic background for yardangs on Mars.

Integrated In-Situ Resource Utilization System Design and Logistics for Mars Exploration

This paper develops an interdisciplinary space architecture optimization framework to analyze the tradeoff on in-situ resource utilization options, identify technology gaps, evaluate the benefits of in-situ resource utilization, and optimize the design of infrastructure for Mars human space exploration scenarios and mission profiles. It performs trade studies from the perspective of space logistics, which takes into account the interplanetary transportation, infrastructure deployment, in-situ resource utilization system operation, and logistics of the produced resources...

Balloon Design for Mars, Venus, and Titan Atmospheres

This paper studies the specifications of balloons for the exploration of bodies with different atmospheric conditions. Three types of balloons, i.e., zero-pressure, super-pressure, and over-pressurized, with four different shapes, i.e., sphere, oblate, prolate, and airship, were analysed....

Designing Mars Missions for the Utilization of Rotorcraft

Following the technical demonstration of the Mars Helicopter on the Mars 2020 mission, interest in further exploration of Mars utilizing rotorcraft is expected to increase. Previously, scientific exploration has been limited by the resolution of instruments on satellites and the terrain a rover can traverse. Rotorcraft enable exploration in previously inaccessible locations with increased efficiency compared to rovers and improved resolution (compared to satellites)...

Water on Mars—A Literature Review

To assess Mars’ potential for both harboring life and providing useable resources for future human exploration, it is of paramount importance to comprehend the water situation on the planet. Therefore, studies have been conducted to determine any evidence of past or present water existence on Mars. While the presence of abundant water on Mars very early in its history is widely accepted, on its modern form, only a fraction of this water can be found, as either ice or locked into the structure of Mars’ plentiful water-rich materials. ...
