Magnetized magma intrusions being sources of a weak and a strong lunar magnetic anomaly revealed by 3D distribution of magnetization

Earth and Planetary Physics
In this work, we aim to investigate the origin of the magnetic carriers in the lunar crust and the intensity of the ancient dynamo field. The magnetization and depth range of magnetic carriers are studied under a weak and a strong magnetic anomaly in ...

Noble gases and nitrogen in material from asteroid Bennu

Meteoritics &Planetary Science, EarlyView.
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Subsoil structure at the Chang’E-6 landing site revealed by in-situ Lunar Regolith Penetrating Radar

Communications Earth & Environment
As humanity’s first sample return mission from the lunar farside, China’s Chang’E-6 mission provides a unique window into understanding the dichotomy in lunar nearside-farside evolution. Chang’E-6 landed in the southwestern Apollo basin (~2.79 Ga) within

Small but mighty: Impact hazards from iron Near‐Earth Objects

Meteoritics &Planetary Science, EarlyView.
Abstract Small asteroids can impact Earth unexpectedly, as demonstrated by the Chelyabinsk event in 2013. The warning times are likely to be short, and the first tools for fast hazard predictions have been developed in the last years for encounters with rocky or cometary objects, which quickly fragment in the atmosphere and cause airbursts. However, in

Sampling the volcanic plumes at Io: Impact speeds and shock conditions

Meteoritics &Planetary Science, EarlyView.
Abstract The desire to sample material from the interior of Io, by flying through its volcanic plumes, requires consideration of the flyby speed and the types of sample collection techniques that can be utilized. Low speed collection (1–2.5 km s−1) would require an orbit around Io itself, which is unlikely due to the accumulated radiation dose that ...

From Insult to Injury: Exploring the Associations Between Severe Malnutrition in Childhood, Rehabilitation Weight Gain and Adult Adiposity in a Prospective Cohort Study

Maternal &Child Nutrition, EarlyView.
Emerging evidence links childhood severe malnutrition to adult cardiometabolic disease risk. Higher admission weight and nutritional oedema predicted adult adiposity while faster rehabilitation weight gain predicted adult adiposity in males only. Rehabilitation weight gain itself was a partial mediator of long‐term adiposity risk.
