Alignment determination of the Hayabusa2 laser altimeter (LIDAR)

Earth, Planets and Space, 2021
In this study, we determined the alignment of the laser altimeter aboard Hayabusa2 with respect to the spacecraft using in-flight data. Since the laser altimeter data were used to estimate the trajectory of the Hayabusa2 spacecraft, the pointing ...

Experimental study on electrostatic migration of different mineral particles composing lunar dust under electron irradiation

Frontiers in Astronomy and Space Sciences, 2023
Dust electrostatic migration is one of the primary causes of dust events on the surface of airless celestial bodies, which can result in multiple dust phenomena, including lunar horizon glow and dust pools, and also offer crucial insights into the ...

Exploring Space Exploring Earth [PDF]

Eos, Transactions American Geophysical Union, 2003
The preface of Exploring Space Exploring Earth states that its objective is “…to explore the impact of space flight on geology and its subsurface counterpart, geophysics…” As promised, some of the book's chapters deal with geophysics—space geodesy, satellite studies of geomagnetism, and remote sensing. Others cover geology—impact cratering, terrestrial

Urban ‘tourism exploration space’: the example of Łódź [PDF]

, 2009
The author refers to the concept of ‘tourism space’ published earlier, and confronts this notion with a definition of ‘urban space’, bearing in mind that both these ‘spaces’ are subspaces of general ‘geographical space’.

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-
