This comprehensive study delves into the significance of asteroid research and proposes a
systematic classification consisting of seven distinct categories. Initially, a concise definition …

NASA's first asteroid sample return mission, OSIRIS-REx, collected a sample from the
surface of near-Earth asteroid Bennu in October 2020 and will deliver it to Earth in …

The Hayabusa2 spacecraft explored C-type near-Earth asteroid (162173) Ryugu and
returned asteroidal materials, collected during two touchdown operations, to the Earth as the …

This research focuses on the design and reconstruction of the first touchdown of Hayabusa2
on the asteroid Ryugu. Because of the plethora of boulders, the landing operation required …

Hayabusa2 deployed two artificial landmarks called “target markers (TMs)” on the asteroid
Ryugu for autonomous landing control. To achieve precise deployment on target landing …

Middle infrared spectral results obtained in‐situ by the Hayabusa2 MARA instrument are
generally in‐line with previous results and a new comparison with sample C0137 returned …

One of the major challenges in the Hayabusa2 sample-return mission was the second
touchdown on the asteroid Ryugu, which was designed to collect subsurface materials near …

Crater morphology and surface age of asteroid (162173) Ryugu are characterized using the
high‐resolution images obtained by the Hayabusa2 spacecraft. Our observations reveal that …

Hayabusa2 took on the challenge of collecting fresh subsurface samples from asteroid
(162173) Ryugu during its second touchdown operation. For this ambitious goal, the …

The exploration of small celestial bodies has been a very active field ever since the dawn of
space exploration. However, traditional approaches based on monolithic landers allow only …
