ISRU Implications for Lunar and Martian Plume Effects [PDF]
In: 47th AIAA Aerospace Sciences Meeting including The New
Horizons Forum and Aerospace Exposition. 05 January 2009 - 08 January 2009.
Orlando, Florida, 2021 Experiments, analyses, and simulations have shown that the engine exhaust plume of a Mars lander large enough for human spaceflight will create a deep crater in the martian soil, blowing ejecta to approximately 1 km distance, damaging the bottom of the lander with high-momentum rock impacts, and possibly tilting the lander as the excavated hole ...

Effects of Spaceflight on Human Induced Pluripotent Stem Cell-Derived Cardiomyocyte Structure and Function. [PDF]
, 2019 With extended stays aboard the International Space Station (ISS) becoming commonplace, there is a need to better understand the effects of microgravity on cardiac function. We utilized human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs)

Towards an integrated scientific and social case for human space exploration [PDF]
, 2004 I will argue that an ambitious programme of human space exploration, involving a return to the Moon, and eventually human missions to Mars, will add greatly to human knowledge. Gathering such knowledge is the primary aim of science, but science's compart-
