TL;DR: The most recent general survey of sinuous rilles (SRs) was conducted in 1969 using Lunar Orbiter IV and V photographs as discussed by the authors, which used higher resolution SELENE and LRO image and topography data to provide detailed observations and measurements of the rilles observed across the lunar surface.

TL;DR: In this paper, the authors used a global geological map of Venus to assess the stratigraphic position of volcanic units and landforms, determine their relationship with structure and tectonics, and identify changes in volcanic style, flux and activity with time.

TL;DR: In this article, the authors compare derived sulfuric acid hydrate (H2SO4·nH2O) abundance with weathering patterns and intensities associated with charged particles from Jupiter's magnetosphere.

TL;DR: Pieters et al. as mentioned in this paper analyzed clear filter images to retrieve the photometric properties of the regolith of the main belt asteroid Vesta and used these results to study variations in albedo and steepness of the phase curve over the surface.

TL;DR: In this paper, data from 47 deep flybys in the time period Octo-2018 to Deco-2019 were presented. But the data were only used for Titan's ionosphere measurements.

TL;DR: In this article, simultaneous radar and video measurements of meteors were made using the Canadian Meteor Orbit Radar (CMOR) and several Gen-III image-intensified CCD cameras primarily to relate radar meteor electron line density, q, to video meteor photon radiant power, I.

TL;DR: In this article, an experimental procedure for precise and accurate measurements of isotope abundances by a miniature laser ablation mass spectrometer for space research is described, which is conducted on different untreated NIST standards and galena samples by applying pulsed UV laser radiation (266 nm, 3 ns and 20 Hz) for ablation, atomisation, and ionisation of the sample material.

TL;DR: In this article, the authors revisited selected models and presented hybrid simulations of the comet-solar wind interaction region performed with the A.I.K.E.F. code.

TL;DR: The extreme ultraviolet spectroscope EXtrem ultraviolet spetroscope for ExosphEric Dynamics (EXCEED) on board the SPRINT-A mission will be launched in the summer of 2013 by the new Japanese solid propulsion rocket Epsilon as its first attempt, and it will orbit around the Earth with an orbital altitude of around 1000 km as discussed by the authors.

TL;DR: In this article, improved radiative transfer simulation and multi-wi ndow retrieval procedures (MWR) are described that are applied to investigate thermal s tructure and cloud features in the nightside atmosphere of Venus over the northern hemisphere.

TL;DR: In this paper, a broad classification of aerosol analogues highlighting the materials that can be more representative of Titan's aerosols in terms of their content of organic volatiles is presented.

TL;DR: In this paper, the authors show a new in situ example of a dipolarization identified in the Cassini magnetometer data and use this formalism to estimate the ionospheric current density that would arise based on in situ tail measurements of the magnetic field and the implications for corresponding auroral electron acceleration.

TL;DR: In this paper, the authors show that most of the Mars ejecta fragments remain trapped in orbits around Mars for several days to several hundred years until they re-impact with Phobos and produce new generations of ejecta.

TL;DR: In this paper, a set of data reduction and analysis strategies were applied to the CRISM imaging spectrometer orbiting Mars in the search for hydrated silicates and the discovery of a new mineral on Mars, epidote, was reported.

TL;DR: In this paper, the authors investigated the morphology, mineralogy, and stratigraphy of light-toned deposits within one trough of Noctis Labyrinthus, centered at −6.8°N, 261.1°E.

TL;DR: In this article, the authors present a study on the properties of electromagnetic plasma waves in the region upstream of the Martian bow shock, detected by the magnetometer and electron reflectometer onboard the Mars Global Surveyor (MGS) spacecraft during the period known as Science Phasing Orbits (SPO).

TL;DR: In this paper, the authors investigate Europa's exospheric O2 characteristics under the external conditions that are likely in the Jupiter's magnetospheric environment, applying the Europa Global model of Exospheric Outgoing Neutrals (EGEON, Plainaki et al., 2012 ) for different configurations between the positions of Europa, Jupiter and the Sun.

TL;DR: In this paper, a new concept of NIR reflectance hyperspectral microscope, MicrOmega, is presented and results obtained both with a representative breadboard and a first version of the MicROmega instrument, recently integrated on the Phobos Grunt lander, are discussed.

TL;DR: In this article, the authors measured the temperature-average heat capacity of a sample of a meteorite by inserting the sample in liquid nitrogen, measuring the mass of nitrogen boiled off due to the heat within the sample, and calibrating against measurements of pure quartz with a temperature-averaged heat capacity.

TL;DR: In this paper, the authors used the projected thicknesses of these deposits as constraints to determine the lifetimes of detectable cryovolcanic plumes that may have emplaced them, and found that easily detectable plumes will have optical depths, τ, greater than or equal to 0.04.

TL;DR: In this paper, the authors used high spectral resolution data (0.074 cm −1 apodised) from the SPIRE shortwave spectrometer array (SSW), which provided the best possible signal-to-noise ratio for detecting any NH3 emission features.

TL;DR: In this paper, the relationship between grain size and beam size was found to be the most important factor in producing a representative LIBSSIM-predicted bulk composition, as grain size increases relative to beam size, accuracy of calculated bulk compositions decreases but chemical information about the nature of the component grains is improved.

TL;DR: In this article, the authors used harmonic regression models to forecast aurora and solar activity for the period 1956-2050 and found that four major multidecadal secular cycles forming an approximate harmonic set at periods of 42.85, 57.13, 85.7 and 171.4 years are very close to the four major heliospheric oscillations relative to the center of mass of the solar system caused by Jupiter, Saturn, Uranus and Neptune.

TL;DR: The Io footprint is a set of auroral spots and an extended tail resulting from the strong interaction between Io and the Jovian magnetosphere as discussed by the authors, and it can be used to measure the precipitated energy fluxes from images on which the emission region is observed at a slant angle.

TL;DR: In this article, the authors investigated the effect of increased partial pressures of N2 on early Mars surface temperature by including pressure broadening of absorption lines and collision-induced N2-N2 absorption.
