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

The Influence of Space Weathering on the Far‐Ultraviolet Reflectance of Apollo‐Era Soils
Abstract Building on our previous studies of the far‐ultraviolet (FUV) reflectance of Apollo soil 10084 and lunar soil simulants JSC‐1A and LMS‐1 (Gimar et al., 2022, https://doi.org/10.1029/2022je007508; Raut et al., 2018, https://doi.org/10.1029/2018je005567), we present new FUV results for Apollo soils 68501 and 71061. Heavily weathered soils (68501,

Additive manufacturing (AM) transforms space hardware by enabling lightweight, high‐performance, and on‐demand production. This review outlines AM processes—powder bed fusion (PBF), directed energy deposition (DED), binder jetting (BJ), sheet lamination (SL), and material extrusion (ME)—applied to propulsion, satellite structures, and thermal devices ...

Robotic Arm Geomechanical Experiments and Analyses to Enable Lunar Science and Settlement
Abstract This study evaluates the capability of a robotic arm equipped with a force‐torque sensor and a specially designed scoop to perform geomechanical characterization of high‐fidelity lunar highlands regolith simulant. Experiments focused on pressure‐sinkage, shear strength, and angle of repose to assess the performance and applicability of the ...

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 ...

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.

Effects of wheel width on running performance of four-wheeled small lunar rover
As future lunar habitation plans progress, the importance of landing-based exploration is increasing. Small lunar rovers are considered effective for such missions due to their low deployment risk and cost. However, these rovers are prone to slippage and

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