Offworld Science Droids: A Review Maps Key Technologies For Small-body Sampling Robots
Unlike planetary rovers operating on the Moon or Mars, robots working on asteroids and comets must interact with surfaces where gravity is extremely weak, terrain is highly irregular, and material […]
The Science From Asteroid Sample Return Missions
To date, three samples from near-Earth asteroids have been delivered to Earth by Japan’s Hayabusa (2010) and Hayabusa2 (2020) missions, and the United States OSIRIS-REx mission (2023).
Discovery Of Unexpectedly Large Organic Molecules from Asteroid Ryugu
Overview Using a high-resolution atomic force microscope ( AFM ), we directly observed the skeletal structures of individual organic molecules extracted from the Ryugu sample. We discovered numerous gigantic organic […]
Hayabusa2 Asteroid Samples Offer New Insights Into Conditions When The Solar System Formed
To uncover the history of our solar system, it is necessary to study the dynamic evolution of the ancient solar nebula materials.
Bundle Adjustment Of Hayabusa2’s ONC Images And Controlled Color Mosaic Map Of Ryugu
JAXA’s Hayabusa2 mission successfully returned samples from the asteroid Ryugu in December 2020. It executed two touchdowns to collect the surface and subsurface materials, one close to the crater created […]
NASA’s Bennu Samples Reveal Complex Origins, Dramatic Transformation
Asteroid Bennu, sampled by NASA’s OSIRIS-REx mission in 2020, is a mixture of dust that formed in our solar system, organic matter from interstellar space, and pre-solar system stardust. Its […]
Astrogeology: Asteroids Bennu And Ryugu Are Part Of The Polana Family
A Southwest Research Institute (SwRI) review of data collected from near-Earth asteroids Bennu and Ryugu supports the hypothesis that they were originally part of the Polana collisional family in the […]
An Unexpected Mineral Discovered In A Grain Of Asteroid Ryugu
The pristine samples from asteroid Ryugu returned by the Hayabusa2 mission on December 6, 2020, have been vital to improving our understanding of primitive asteroids and the formation of the […]
Exploring Seismic Signal Detection and Source Identification of Atmospheric Entries: The Hayabusa2 Sample Return Capsule as a Benchmark
This exploratory study investigates whether seismic signals can be used to infer fragmentation during a fireball event. Re-entry objects, particularly sample return capsules (SRCs) such as the one from the […]
