JAXA curation for Bennu samples returned by the NASA's OSIRIS‐REx mission

Meteoritics &Planetary Science, EarlyView.
Abstract NASA's OSIRIS‐REx mission successfully collected and returned ~121.6 g of bulk samples from the B‐type, near‐Earth asteroid (101955) Bennu to Earth in September 2023. Upon returning to Earth, the samples were transported to the NASA Johnson Space Center where most of the samples have been stored and processed.

Study of the Effect of Martian Dust Storms on Ionospheric Electron Density Based on Physical-grid Deep Neural Learning Technology

The Astrophysical Journal, 2023
The behavior of the Martian ionosphere during global dust storms has always been a popular topic. Based on many Mars Atmosphere and Volatile Evolution observations, a Martian ionospheric electron density model is constructed herein using a physical-grid ...

Measurements of Forbush decreases at Mars: both by MSL on ground and by MAVEN in orbit

, 2017
The Radiation Assessment Detector (RAD), on board Mars Science Laboratory's (MSL) Curiosity rover, has been measuring ground level particle fluxes along with the radiation dose rate at the surface of Mars since August 2012. Similar to neutron monitors at

Sulfur‐bearing serpentine in carbonaceous chondrites

Meteoritics &Planetary Science, EarlyView.
Abstract A correlative multi‐technique approach, including electron microscopy and X‐ray synchrotron work, has been used to obtain both structural and compositional information of a sulfur‐bearing serpentine identified in several carbonaceous chondrites (Winchcombe CM2, Aguas Zarcas CM2, Ivuna CI, and Orgueil CI), and in Ryugu samples returned by the ...

Observations of Locally Generated Whistler-mode Waves in the Martian Magnetotail Current Sheet

The Astrophysical Journal, 2023
The whistler-mode wave is an electromagnetic wave that commonly occurs in space plasma and has been extensively studied, especially within the Earth's magnetosphere. They have also been reported in the near-Mars space, such as Martian upstream solar wind,

Textural and geochemical diversity of impact melt rock clasts in Apollo 16 sample 67015: Implications for the provenance of impact ejecta in the lunar highlands

Meteoritics &Planetary Science, EarlyView.
Abstract Apollo sample 67015 has been classified as a fragmental breccia comprised of highlands‐type clasts and is proposed to be the most complex Apollo 16 sample. 67015 is dominated by impact melt rock clasts that display a variety of textures, which have been previously interpreted to be indicative of multiple impact events.

Direct Observations of Magnetic Reconnections at the Magnetopause of the Martian Mini‐Magnetosphere

Geophysical Research Letters
While Mars lacks a global intrinsic magnetic field, it does exhibit crustal magnetic anomalies (mostly in its Southern Hemisphere). These crustal magnetic anomalies directly interact with solar wind, which forms a mini‐magnetosphere and a region denoted ...

Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

The Mars system revealed by the Martian Moons eXploration mission

Earth, Planets and Space, 2022
Japan Aerospace Exploration Agency (JAXA) plans a Phobos sample return mission (MMX: Martian Moons eXploration). In this study, we review the related works on the past climate of Mars, its evolution, and the present climate and weather to describe the ...
