Asteroid (162173) Ryugu is a pristine carbonaceous asteroid recently sampled by JAXA during the Hayabusa2 mission. Chemical, isotopic, and contextual measurements suggest that Ryugu is genetically linked to Ivuna-type (CI) […]
JAXA’s Hayabusa2 mission returned ~5.4 grams of material from the C-type asteroid Ryugu. Studies have shown that this material resembles the CI (Ivuna-type) carbonaceous chondrites, which are primitive meteorites that […]
In December 2020, the Hayabusa2 mission of the Japan Aerospace Exploration Agency (JAXA) returned samples from the near-Earth, C-type asteroid (162173) Ryugu. C-type asteroids have spectral properties similar to carbonaceous chondrite […]
The Hayabusa2 mission, executed by the Japan Aerospace Exploration Agency (JAXA), provided direct access to some of the most pristine astromaterials investigated on Earth thus far. These materials were collected […]
The Hayabusa2 mission was launched on December 3, 2014, with the goal of collecting samples from the asteroid (162173) Ryugu. The Hayabusa2 spacecraft made two landings on Ryugu and collected […]
The Japan Aerospace Exploration Agency (JAXA) Hayabusa2 mission to asteroid Ryugu investigated its surface from 2018 to 2020 and successfully returned approximately 5.4 grams of Ryugu samples to Earth in […]
On February 22, 2019, the Hayabusa2 mission of the Japan Aerospace Exploration Agency (JAXA) collected samples of rock and dust from the surface of near-Earth asteroid Ryugu, but it has […]
Water and organics may have been delivered to the inner solar system by volatile-rich asteroids that migrated in from the outer solar system. The Hayabusa2 and OSIRIS-REx spacecraft were recently […]
The Japan Aerospace Exploration Agency’s Hayabusa2 spacecraft successfully performed an artificial impact experiment on the surface of near-Earth asteroid Ryugu on April 5, 2019. The experiment entailed firing a two-kilogram […]
The Hayabusa2 mission led by the Japan Aerospace Exploration Agency (JAXA) has successfully returned materials from the asteroid Ryugu to Earth. Ryugu is a near-Earth asteroid of primitive carbonaceous chondrite-like […]
A study published in the Proceedings of the National Academy of Sciences reports the presence of ribose and other bio-essential sugars, including arabinose and xylose, in two carbonaceous meteorites, Murchison […]
