Crop growth and viability of seeds on Mars and Moon soil simulants

Open Agriculture, 2019
If humans are going to establish a base on the Moon or on Mars they will have to grow their own crops. An option is to use Lunar and Martian regolith. These regoliths are not available for plant growth experiments, therefore NASA has developed regolith ...

A mobile planetary lander utilizing elastic loop suspension [PDF]

, 1976
Efforts to increase the cost effectiveness of future lunar and planetary rover missions have led to the mobile lander concept, which replaces the landing legs of a soft-lander craft with a compact mobility system of sufficient strength to withstand the ...

A Study Demonstrating That Using Gravitational Offset to Prepare Extraterrestrial Mobility Missions Is Misleading

Journal of Field Robotics, Volume 42, Issue 7, Page 3772-3794, October 2025.
ABSTRACT Recently, there has been a surge of international interest in extraterrestrial exploration targeting the Moon, Mars, the moons of Mars, and various asteroids. This contribution discusses how current state‐of‐the‐art Earth‐based testing for designing rovers and landers for these missions currently leads to overly optimistic conclusions about ...

Analysis of four Apollo 16 double drive tubes using QEMSCAN® mapping techniques: Implications for sampling the lunar regolith in highland terrains

Meteoritics &Planetary Science, Volume 60, Issue 10, Page 2504-2523, October 2025.
Abstract The lunar regolith contains a rich history of Solar System impact events and solar activity. Many future missions will land in the south polar region of the Moon, a heavily impact cratered highland terrain, similar to the Apollo 16 landing site.

Discovery of a Lunar Cold Spot at Apollo 16's South Ray Crater

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract Lunar cold spots are extensive, ray‐like regions of reduced nighttime temperature surrounding young impact craters. Using improved Diviner temperature maps, we identify a faint cold spot surrounding South Ray crater at the Apollo 16 landing site.

Study on Mechanical Properties of QH-E Lunar Soil Simulant under Conventional Triaxial and Cyclic Triaxial Tests

Journal of Physics: Conference Series
Study of the mechanical properties of lunar soil simulant is the key to conducting lunar soil sampling and lunar base construction. In this paper, conventional and cyclic triaxial tests are performed by using discrete element method (DEM) to study the ...

A Goniometric System for Photometric and Polarization Measurements of Planetary Regolith Analogs

Earth and Space Science, Volume 12, Issue 9, September 2025.
Abstract The Planetary Surface Texture Laboratory at the Johns Hopkins University Applied Physics Laboratory is a facility for the study of the photometric and polarization behavior of regolith analogs using an ∼1.5‐m‐radius arc goniometer system. This system characterizes the photometric and polarization response of granular materials (planetary ...
