title: Mars seismology

description: For the first time, from early 2019 to end of 2022, Mars shallow and deep interior have been explored by seismology with the InSight mission. Thanks to the performances of its seismometers and quality of their robotic installation on the ground, more than 1300 seismic events have been detected, including about 90 marsquakes at teleseismic distances, with Mw from 2.5 to 4.7, and 6 impacts, the largest ones with craters larger than 130m. A large fraction of these marsquakes occur in Cerberus Fossae, demonstrating active regional tectonics. Records of pressure induced seismic noise and of heat flow penetration seismic signal have provided subsurface models below the lander. Deeper, direct and secondary body wave phases travel time, receiver function and surface waves analysis have provided the first interior models of Mars, including crustal thickness and crustal layering, mantle structure, thermal lithospheric thickness and core radius and state.

title: Comparison of Optimal Estimation HDO/H2O Retrievals from AIRS with ORACLES measurements

description: 9 In this paper we evaluate new retrievals of the deuterium content of water vapor from the 20 Aqua Atmospheric InfraRed Sounder (AIRS) with aircraft measurements of HDO and 21 H2O from the ObseRvations of Aerosols above Clouds and their intEractionS 22 (ORACLES) field mission. Single footprint AIRS radiances are processed with an 23 optimal estimation algorithm that provides vertical profiles of the HDO/H2O ratio, 24 characterized uncertainties, and instrument operators (i.e., averaging kernel matrix). 25 These retrievals are compared to vertical profiles of the HDO/H2O ratio from the Oregon 26 State University Water Isotope Spectrometer for Precipitation and Entrainment Research 27 (WISPER) on the ORACLES NASA P-3B Orion aircraft. Measurements were taken over 28 the Southeast Atlantic Ocean from 31 August to 25 September 2016. HDO/H2O is 29 commonly reported in dD notation, which is the fractional deviation of the HDO/H2O 30 ratio from the standard reference ratio. For collocated measurements, the satellite 31 instrument operator (averaging kernels and a priori constraint) is applied to the aircraft 32 profile measurements. We find that AIRS dD bias relative to the aircraft is well within 33 the estimated measurement uncertainty. In the lower troposphere, 1000 to 800 hPa, AIRS 34 dD bias is -6.6‰ and the Root Mean Square (RMS) deviation is 20.9‰, consistent with 35 the calculated uncertainty of 19.1‰. In the mid-troposphere, 800 to 500 hPa, AIRS dD 36 bias is -6.8‰ and RMS 44.9‰, comparable to the calculated uncertainty of 25.8‰.

title: THE MADDEN JULIAN OSCILLATION IN CCSM4

description: The change in Madden–Julian oscillation (MJO) amplitude and variance in response to anthropogenic climate change is assessed in the 1 nominal resolution community climate system model, version 4 (CCSM4), which has a reasonable representation of the MJO characteristics both dynamically and statistically. The twentieth century CCSM4 run is compared with the warmest twenty-first century projection (representative concentration pathway 8.5, or RCP8.5). The last 20 years of each simulation are compared in their MJO characteristics, including spatial variance distributions of winds, precipitation and outgoing longwave radiation, histograms of event amplitude, phase and duration, and composite maps of phases. The RCP8.5 run exhibits increased variance in intraseasonal precipitation, larger-amplitude MJO events, stronger MJO rainfall in the central and eastern tropical Pacific, and a greater frequency of MJO occurrence for phases corresponding to enhanced rainfall in the Indian Ocean sector. These features are consistent with the concept of an increased magnitude for the hydrological cycle under greenhouse warming conditions. Conversely, the number of active MJO days decreases and fewer weak MJO events occur in the future climate state. These results motivate further study of these changes since tropical rainfall variability plays such an important role in the region’s socio-economic well being.

title: Architected Lattices with Adaptive Energy Absorption

description: Energy absorbing materials, like foams used in protective equipment, are able to undergo large deformations under low stresses, reducing the incoming stress wave below an injury or damage threshold. They are typically effective in absorbing energy through plastic deformation or fragmentation. However, existing solutions are passive, only effective against specific threats and they are usually damaged after use. Here, we overcome these limitations designing energy absorbing materials that use architected lattices filled with granular particles. We use architected lattices to take advantage of controlled bending and buckling of members to enhance energy absorption. We actively control the negative pressure level within the lattices, to tune the jamming phase transition of the granular particles, inducing controllable energy absorption and recoverable deformations. Our system shows tunable stiffness and yield strength by over an order of magnitude, and reduces the transmitted impact stress at different levels by up to 40% compared to the passive lattice. The demonstrated adaptive energy absorbing system sees wide potential applications from personal protective equipment, vehicle safety systems to aerospace structures.

title: A deep X-ray view of the bare AGN Ark120. IV. XMM-Newton and NuSTAR spectra dominated by two temperature (warm, hot) Comptonization processes.

description: Context. The physical characteristics of the material closest to supermassive black holes (SMBHs) are primarily studied through X-ray observations. However, the origins of the main X-ray components such as the soft X-ray excess, the FeK line complex, and the hard X-ray excess are still hotly debated. This is particularly problematic for Active Galactic Nuclei (AGN) showing a significant intrinsic absorption, either warm or neutral, which can severely distort the observed continuum. Therefore, AGN with no (or very weak) intrinsic absorption along the line of sight, so-called “bare AGN”, are the best targets to directly probe matter very close to the SMBH. Aims. We perform an X-ray spectral analysis of the brightest and cleanest bare AGN known so far, Ark 120, in order to determine the process(es) at work in the vicinity of the SMBH. Methods. We present spectral analysis of data from an extensive campaign observing Ark 120 in X-rays with XMM-Newton (4120 ks, 2014 March 18–24), and NuSTAR (65.5 ks, 2014 March 22). Results. During this very deep X-ray campaign, the source was caught in a high flux state similar to the earlier 2003 XMM-Newton observation, and about twice as bright as the lower-flux observation in 2013. The spectral analysis confirms the “softer when brighter” behaviour of Ark 120. The four XMM-Newton/pn spectra are characterized by the presence of a prominent soft X-ray excess and a significant FeK complex. The continuum is very similar above about 3 keV, while significant variability is present for the soft X-ray excess. We find that relativistic reflection from a constant-density, flat accretion disk cannot simultaneously produce the soft excess, broad FeK complex, and hard X-ray excess. Instead, Comptonization reproduces the broadband (0.3–79 keV) continuum well, together with a contribution from a mildly relativistic disk reflection spectrum. Conclusions. During this 2014 observational campaign, the soft X-ray spectrum of Ark 120 below 0.5 keV was found to be dominated by Comptonization of seed photons from the disk by a warm (kT0.5 keV), optically-thick corona (9). Above this energy, the X-ray spectrum becomes dominated by Comptonization from electrons in a hot optically thin corona, while the broad FeK line and the mild Compton hump result from reflection o the disk at several tens of gravitational radii.

title: X-Ray Ionization of Planet-Opened Gaps in Protostellar Disks

description: Young planets with masses approaching Jupiter's have tides strong enough to clear gaps around their orbits in the protostellar disk. Gas ow through the gaps regulates the planets' further growth and governs the disks' evolution. Magnetic forces may drive that ow if the gas is suciently ionized to couple to the elds. We compute the ionizing eects of the X-rays from the central young star, using Monte Carlo radiative transfer calculations to nd the spectrum of Comptonscattered photons reaching the planet's vicinity. The scattered X-rays ionize the gas at rates similar to or greater than the interstellar cosmic ray rate near planets the mass of Saturn and of Jupiter, located at 5 au and at 10 au, in disks with the interstellar mass fraction of sub-micron dust and with the dust depleted a factor 100. Solving a gas-grain recombination reaction network yields charged particle populations whose ability to carry currents is sucient to partly couple the magnetic elds to the gas around the planet. Most cases can undergo Hall shear instability, and some can launch magnetocentrifugal winds. However the material on the planet's orbit has diusivities so large in all the cases we examine, that magneto-rotational turbulence is prevented and the non-ideal terms govern the magnetic eld's evolution. Thus the ow of gas in the gaps opened by the young giant planets depends crucially on the finite conductivity.

title: Description of chloramphenicol resistant Kineococcus rubinsiae sp. nov. isolated from a spacecraft assembly facility

description: A Gram-positive, coccoid, motile, aerobic bacterium, designated strain B12T was isolated from a Jet Propulsion Laboratory spacecraft assembly cleanroom, Pasadena, CA, USA. Strain B12T was resistant to chloramphenicol (100 µg/mL), and is a relatively slow grower (3 to 5 days optimal growth). Strain B12T was found to grow optimally at 28 to 32˚C, pH 7 to 8, and 0.5 % NaCl. Fatty acid methyl ester analysis showed that the major fatty acid of the strain B12T was anteiso C15:0 (66.3%), which is also produced by other Kineococcus species. However, arachidonic acid (C20:4 ω6.9.12.15c) was present in strain B12T and Kineococcus glutinatus YIM 75677T but absent in all other Kineococcus species. 16S rRNA analysis revealed that strain B12T was 97.9% similar to Kineococcus radiotolerans and falls within the Kineococcus clade. Low 16S rRNA gene sequence similarities (&lt;94%) with other genera in the family Kineosporiaceae, including Angustibacter (93%), Kineosporia (94% to 95%), Pseudokineococcus (93%), Quadrisphaera (93%), and Thalassiella (94%) demonstrated that the strain B12T does not belong to these genera. Phylogenetic analysis of the gyrB gene show that all known Kineococcus species exhibited &lt;86% sequence similarity with B12T. Multi-locus sequence and whole genome sequence analyses confirmed that B12T clades with other Kineococcus species. Average nucleotide identity of strain B12T were 75-78% with other Kineococcus species, while values ranged from 72-75% with species from other genera within family Kineosporiaceae. Average amino-acid identities were 66-72% with other Kineococcus species, while they ranged from 50-58% with species from other genera. The dDDH comparison of strain B12T genome with members of genera Kineococcus showed 20-22% similarity, again demonstrating that B12T is distantly related to other members of the genus. Furthermore, analysis of whole proteome deduced from WGS places strain B12T in order Kineosporiales, confirming that strain B12T is a novel member of family Kineosporiaceae. Based on these analyses and other genome characteristics, strain B12T is assigned to a novel species within the genera Kineococcus, and the name Kineococcus rubinsiae sp. nov., is proposed. The type strain is B12T (=FJII-L1-CM-PAB2T; NRRL B-65556T, DSM 110506T).

title: How does organic ice condensation affect the observable optical properties of Pluto’s haze particles?

description: The flyby of the New Horizons spacecraft in July 2015 revealed an unexpected cold atmosphere of Pluto and confirmed the existence of its atmospheric haze. The observed and simulated vertical profiles of chemical species and microphysical processes suggest that the haze particles in Pluto’s middle and lower atmosphere may contain organic ice condensation. Such organic ice components can potentially affect Pluto’s haze chemistry and optical properties, as well as its energy budget. This study investigates the influence of the ice components on the scattering properties of Pluto’s haze by comparing New Horizons observations and simulated particle scattering properties. Comprehensive tests are performed for various haze particle parameters, including their size, chemical component, ice content, and morphology. Scattering properties of these ice-bearing haze particles are calculated by a discrete dipole approximation method and compared to multi-spectral observations obtained by four New Horizons instruments in spectral regions ranging from the ultraviolet to the near-infrared. The results indicate that the inclusion of the organic ice component leads to higher ratios of backscattering in the visible and forward scattering in the near-infrared to extinction in the ultraviolet; this provides better agreement with observations, but it alone is not sufficient to explain the observed forward scattering values in the visible. Therefore, other scattering sources and/or mechanisms are still required to explain the full set of scattering observations. Further observations as well as laboratory measurements and numerical tests are anticipated to improve our understanding of the morphology and ice content of Pluto’s haze.

title: Perspective: Future Exploration of Io

description: Io is the best natural laboratory in the Solar System to study the intertwined processes of tidal heating, extreme volcanism, and atmospheric–magne- tosphere–surface interactions. While substantial advances can be made with forthcoming ground- and space-based observatories, many outstanding questions can only be addressed with in situ measurements at Io. Several space- craft will explore the Jupiter system in the next decade, but their capabilities to investigate Io are limited. A dedicated Io mission is necessary to capitalize on Io’s scientific potential. Previous Io mission concepts have spanned the gamut, including small spacecraft, multiple-flyby missions, orbiters, and landers. New technologies, including advanced solar power and radiation hardening, make Io exploration more tractable, and the potential for contemporaneous measurements from multiple spacecraft in the Jupiter system make a modern Io mission all the more compelling.
