Statistical and superposed epoch study of dipolarization events using data from Wind perigee passes [PDF]

open access: yesAnnales Geophysicae, 2005
From 1995 to 2000, the Wind spacecraft spent over 500h in the magnetotail, much of it within ~2x104km of the predicted location of the neutral sheet.

Special spherical mobile robot for planetary surface exploration: A review

open access: yesInternational Journal of Advanced Robotic Systems, 2023
Considering the requirements of high scientific return, low cost, less complexity, and more reliability for the robot proposed by the extreme environment exploration task on the planet surface, this article comprehensively reviews the history of the ...

Simulating microbial processes in extraterrestrial, aqueous environments [PDF]

open access: yesJournal of Microbiological Methods, 2020
Finding evidence of life elsewhere in the Solar System is dependent on understanding biotic processes that could occur within potentially habitable environments. Here, we describe a suite of high-pressure flow-through reactors that have been developed to investigate biotic and abiotic processes within simulated sub-surface martian and icy moon ...

An overview of experimental simulations of microbial activity in early Earth

open access: yesFrontiers in Microbiology, 2023
Microbial activity has shaped the evolution of the ocean and atmosphere throughout the Earth history. Thus, experimental simulations of microbial metabolism under the environment conditions of the early Earth can provide vital information regarding ...

Coordinated polar spacecraft, geosynchronous spacecraft, and ground-based observations of magnetopause processes and their coupling to the ionosphere [PDF]

open access: yesAnnales Geophysicae, 2004
In this paper, we present in-situ observations of processes occurring at the magnetopause and vicinity, including surface waves, oscillatory magnetospheric field lines, and flux transfer events, and coordinated observations at geosynchronous orbit by ...

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 229-246., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The Adaptability of Life on Earth and the Diversity of Planetary Habitats

open access: yesFrontiers in Microbiology, 2017
The evolutionary adaptability of life to extreme environments is astounding given that all life on Earth is based on the same fundamental biochemistry. The range of some physicochemical parameters on Earth exceeds the ability of life to adapt, but stays ...

The discovery of ETI as a high-consequence, low-probability event [PDF]

open access: yes, 2011
The authors use the opportunity of presenting a paper during the 51st International Astronautical Congress in Rio de Janeiro to introduce a numerical method of characterizing the potential significance of any announcement of discovery of extraterrestrial

Novel solvent systems for in situ extraterrestrial sample analysis [PDF]

open access: yes, 2010
The life marker chip (LMC) is being designed to test for the chemical signature of life in the soil and rocks of Mars. It will use an antibody array as part of its detection and characterisation system and aims to detect both polar and non-polar ...
