Analisis Pengembangan Koleksi Perpustakaan Institut Teknologi Indonesia

open access: yesTik Ilmeu: Jurnal Ilmu Perpustakaan dan Informasi, 2022
The present study aims to investigate the process of collection development in the library of Institut Teknologi Indonesia. The researcher applies the six stages of collection development from Evans (2005) as the theoretical framework.

Properties and models of the Martian bow shock

open access: yes地球与行星物理论评, 2021
Mars does not have a global magnetic field of the internal origin, thus, the solar wind plasma can interact directly with the upper atmosphere and the ionosphere and be shocked with the mass-loading and magnetic pileup processes.

What Martian Meteorites Reveal About the Interior and Surface of Mars

open access: yesJournal of Geophysical Research: Planets, 2020
Martian meteorites are the only direct samples from Mars, thus far. Currently, there are a total of 262 individual samples originating from at least 11 ejection events.

Is the Martian crust also the Martian elastic lithosphere? [PDF]

open access: yesJournal of Geophysical Research: Planets, 2002
Correlations between topography, gravity, and areoid on Mars are used to constrain the crustal and lithospheric thicknesses on the planet. Assuming that the Hellas basin is in isostatic equilibrium with Airy compensation, point correlations between areoid anomalies and topography are used to obtain the mean crustal density and the crustal thickness.

Martian buildings: structural forms using in-place sources

open access: yesScientific Reports, 2022
On Mars, structural loads and the low tensile strength of in-place Martian binders make existing solutions for Martian structures uneconomical because they are based on the terrestrial sources like inflatable units.

Demonstrating Martian gravity [PDF]

open access: yesPhysics Education, 2015
The surface gravity on Mars is smaller than the surface gravity on Earth, resulting in longer falling times. This effect can be simulated on Earth by taking advantage of air resistance and buoyancy, which cause low density objects to fall slowly enough to approximate objects falling on the surface of Mars.

Surficial geology and geomorphology of Greg crater, Promethei Terra, Mars

open access: yesJournal of Maps, 2020
Greg crater, located in Promethei Terra, Mars is a ∼66 km diameter impact crater. The crater has been widely studied, both in terms of its overall geomorphological evolution and, more specifically, its ice-rich landforms.

First estimations of Gravity Wave Potential Energy in the Martian thermosphere: An analysis using MAVEN NGIMS data [PDF]

open access: yesMNRAS 2021, 2021
First estimations of Gravity Wave Potential Energy (GWPE) for the Martian thermosphere are reported herein using the height profile of CO2 density derived temperature fluctuations for different Martian seasons during the 33rd Martian year. Explicit diurnal evolution of GWPE (for 52o to 73o latitude bin) with a post sunset maximum is delineated for ...

Mineralogical characterization of Martian Jezero crater from MRO CRISM hyperspectral images [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014
Martian mineral detection and mapping can provide important information and constraints on Martian aqueous history, which can be used to assess the potential habitability of Mars.

Distribution of Dune Landform on Mars

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Dune landforms are widely distributed on Mars and contain abundant information about the Martian atmosphere and sedimentary environment. At present, the understanding of Martian dunes and their environmental significance still needs to be further ...
