Background: As a component of health promoting school, a school curriculum for health education was considered a fundamental. This survey aimed to identify the components of health-related topics and in which subjects were they taught.

Methods: Four topics were chosen: (i) hygiene, (ii) mental health, (iii) nutrition-oral Health, and (iv) environmental education related to global warming in Education for Sustainable Development (ESD).

Carbonaceous asteroids, such as (101955) Bennu, preserve material from the early Solar System, including volatile compounds and organic molecules. We report spacecraft imaging and spectral data collected during and after retrieval of a sample from Bennu's surface. The sampling event mobilized rocks and dust into a debris plume, excavating a 9-meter-long elliptical crater.

Article Synopsis
  • - NASA's OSIRIS-REx mission successfully collected a sample from asteroid Bennu in October 2020, with plans to deliver it to Earth in September 2023, despite challenges in finding suitable collection sites due to unexpected surface conditions.
  • - A "Sampleability Map" was created to identify and evaluate potential sampling locations on Bennu based on how compatible they were with the spacecraft's sampling mechanism, using a scoring system called "sampleability."
  • - The sampleability algorithm assessed surface properties on two levels: globally to understand Bennu's surface as a whole and site-specifically for higher-resolution predictions at targeted collection spots, ultimately aiding in choosing the optimal collection location.

Soft γ-ray repeaters exhibit bursting emission in hard X-rays and soft γ-rays. During the active phase, they emit random short (milliseconds to several seconds long), hard-X-ray bursts, with peak luminosities of 10 to 10 erg per second. Occasionally, a giant flare with an energy of around 10 to 10 erg is emitted.

The composition of asteroids and their connection to meteorites provide insight into geologic processes that occurred in the early Solar System. We present spectra of the Nightingale crater region on near-Earth asteroid Bennu with a distinct infrared absorption around 3.4 micrometers.
