Spirulina supported plant growth in regolith simulants and elevated levels of CO2

open access: yesFrontiers in Space Technologies
IntroductionA key element for sustainable off-world habitation is the ability to grow food through in-situ resource utilization (ISRU). Growth substrates are required to overcome the challenges of ISRU in the space environment, including the use of ...

Improving inertial separating penetrators considering the features of their impact penetration into the studied celestial bodies [PDF]

open access: yesОмский научный вестник: Серия "Авиационно-ракетное и энергетическое машиностроение"
The article considers factors that can negatively affect the creation of reliable radio communication between an inertial separating penetrator after its impact penetration into the soil of the studied celestial body and an orbital vehicle. The authors

Distinct element method for static and flow mobility characteristics of lunar regolith based on particle shape characteristics

open access: yesYantu gongcheng xuebao
Since it exhibits uniquely grain shape, physical and mechanical characteristics, the lunar regolith is extremely important for utilization of in-situ resources, selection of base station location and construction in lunar exploration.

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

open access: yesOpen 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 ...

Sintering lunar regolith pellets: a comparison of four samples from Apollo 11, 15, and 16

open access: yesMaterials Today Advances
Lunar regolith sintering is proposed as a technique to produce consolidated objects on the lunar surface from locally sourced materials. Understanding the sintering behaviour of real lunar regolith is necessary to optimise this process, however, due to ...

A novel theoretical approach to predict the interannual variability of sulfur in Mercury’s exosphere and subsurface

open access: yesFrontiers in Astronomy and Space Sciences
The surfaces of airless bodies are constantly weathered by ions, meteoroids, and radiation, leading to the ejection of surface atoms to form a tenuous, collisionless atmosphere around the body.
