ASTROBIOLOGIA EM CONSONÂNCIA COM A BNCC: POSSIBILIDADES DE APLICAÇÕES NO ENSINO FUNDAMENTAL II

Caderno de Física da UEFS, 2020
O presente artigo tem como objetivo discorrer sobre a inserção da Astrobiologia na disciplina de Ciências, nas séries iniciais e finais do ensino fundamental. A Astrobiologia tem a particularidade de despertar a curiosidade e o interesse dos discentes em tentar compreender como surgiu a vida na Terra e se existe vida em outro planeta.

Source to Accretion Disk Tilt [PDF]

, 2010
Many different system types retrogradely precess, and retrograde precession could be from a tidal torque by the secondary on a misaligned accretion disk. However, a source to cause and maintain disk tilt is unknown.

Surface Dust Coverages on Rock Targets in Gale Crater: Influence of Elevation, Proximity to Aeolian Sand Fields and Seasonality

Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract Martian dust is mobilized throughout the year by local, regional, and global dust storms, influencing atmospheric opacity and inhibiting observations of the surface. Using Mars Hand Lens Imager (MAHLI) images and methods of Schmidt et al. (2018), https://doi.org/10.1029/2018je005553, areal dust coverages on 368 near‐horizontal, undisturbed ...

Nighttime and Early Morning Atmospheric Waves and Transient Turbulence at Jezero Crater, Mars, Observed by the Perseverance Rover

Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract We study atmospheric oscillations in Jezero crater, Mars, that occur at night and dawn over stable conditions of the planetary boundary layer. These atmospheric oscillations are sporadic and can have large amplitudes, resulting in important variations in the dynamic conditions of the atmosphere.

Dust Lifting and Deposition Over Six Mars Years at Gale Crater, Mars, From REMS Observations and Mesoscale Simulations

Journal of Geophysical Research: Planets, Volume 130, Issue 6, June 2025.
Abstract We present the temporal evolution of the effect of dust accumulation on two surfaces of the Curiosity rover at Gale crater during almost 4,000 sols using Rover Environmental Monitoring Station (REMS), Chemcam and Mastcam observations, and compare it with simulations of the Mars Weather Research and Forecasting Model (MarsWRF) atmospheric ...

Collection and In Situ Analyses of Regolith Samples by the Mars 2020 Rover: Implications for Their Formation and Alteration History

Journal of Geophysical Research: Planets, Volume 130, Issue 2, February 2025.
Abstract The Perseverance rover has sampled mm‐size lithic fragments containing olivine likely from at least two source regions from the surface of an inactive megaripple surface, and fine‐grained material from the surface and to a depth of ∼4–6 cm. Some of the mm‐size grains lack a coherent diffraction pattern measured by PIXL, consistent with the ...

Herschel observations of EXtra-Ordinary Sources (HEXOS): Observations of H_2O and its isotopologues towards Orion KL [PDF]

, 2010
We report the detection of more than 48 velocity-resolved ground rotational state transitions of H^(16)_2O, H^(18) _2O, and ^(17)_2O – most for the first time – in both emission and absorption toward Orion KL using Herschel/HIFI.

WindSightNet: The Inter‐Annual Variability of Martian Winds Retrieved From InSight's Seismic Data With Machine Learning

Journal of Geophysical Research: Planets, Volume 130, Issue 2, February 2025.
Abstract Wind measurements from landed missions on Mars are vital to characterize the near surface atmospheric behavior on Mars and improve atmospheric models. These winds are responsible for aeolian change and the mixing of dust in and out of the atmosphere, which has a significant effect on global circulation.
