TUCSON, Ariz. (University of Arizona PR) — Scientists thought asteroid Bennu’s surface would be like a sandy beach, abundant in fine sand and pebbles, which would have been perfect for collecting samples. Past telescope observations from Earth’s orbit had suggested the presence of large swaths of fine-grain material called fine regolith that’s smaller than a few centimeters.

TOKYO (JAXA PR) — Research results from the exploration of Ryugu by the asteroid explorer, Hayabusa2, have been published in the British online journal, Nature Astronomy, on May 24, 2021 (May 25 JST). Assistant Professor Naoya Sakatani (Rikkyo University) from the Hayabusa2 science team is the lead author in this research.
Rocks on Ryugu, a “rubble pile” near-Earth asteroid recently visited by Japan’s Hayabusa2 spacecraft, appear to have lost much of their water before they came together to form the asteroid, new research suggests.
PROVIDENCE, R.I. (Brown University PR) — Last month, Japan’s Hayabusa2 mission brought home a cache of rocks collected from a near-Earth asteroid called Ryugu. While analysis of those returned samples is just getting underway, researchers are using data from the spacecraft’s other instruments to reveal new details about the asteroid’s past.
The Japanese Hayabusa-2 mission returned at least 5.4 g of dust from the asteroid Ryugu. That’s 50 times more than expected! These unpublished samples could contain primitive organic molecules that played a role in the emergence of life on Earth.
PARIS (CNES PR) — A fabulous Christmas present! A harvest beyond expectations! A dream come true … Words fail to qualify the extraordinary success of the Hayabusa2 mission which deposited on December 6, 2020, in the Australian desert, a 40 cm diameter capsule containing a treasure: at least 5.4 g material from asteroid Ryugu.

GREENBELT, Md. — On Dec. 6 local time (Dec. 5 in the United States), Japanese spacecraft Hayabusa2 dropped a capsule to the ground of the Australian Outback from about 120 miles (or 200 kilometers) above Earth’s surface. Inside that capsule is some of the most precious cargo in the solar system: dust that the spacecraft collected earlier this year from the surface of asteroid Ryugu.
PARIS (ESA PR) — The team behind ESA’s Hera asteroid mission for planetary defence congratulates JAXA for returning Hayabusa2’s capsule to Earth laden with pristine asteroid samples. They look forward to applying insights from this audacious space adventure to their own mission.

Today marks an exciting and historic event as precious samples from asteroid Ryugu have been brought to Earth by the Japan Aerospace Exploration Agency’s (JAXA) Hayabusa2 mission. This is an extremely challenging endeavor and we commend and congratulate Japan on being not only the first nation that has been able to carry out a successful asteroid retrieval mission, but to now have done so for the second time!
HOUSTON (NASA PR) — When the OSIRIS-REx spacecraft touches asteroid Bennu, it will capture NASA’s first sample from an asteroid and provide rare specimens for research that scientists hope will help them shed light on the many mysteries of our solar system’s formation.
The sample is scheduled for return to Earth in 2023 to be examined and stored in state-of-the-art curation facilities now under construction at Johnson Space Center in Houston. The labs will be managed by NASA’s Astromaterials Research and Exploration Science division, also known as ARES. The division is home to the world’s greatest astromaterials collections — including lunar rocks, solar wind particles, meteorites, and comet samples — and some of the experts who research them.
Intensity of the landing impact on Mars’ moon Phobos is being tested with a rover model.
The housing of the rover consists of a lightweight construction made of carbon-fibre-reinforced polymers (CFRP).
The landing on Phobos is planned for late 2026 or early 2027 as part of the MMX mission
BREMEN, Germany (DLR PR) — The Japan Aerospace Exploration Agency (JAXA) Martian Moons eXploration (MMX) mission will have a German-French rover on board when it is launched in 2024. The rover will land on the Martian moon Phobos and explore its surface for approximately three months.
Initial landing tests are currently underway at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Landing and Mobility Test Facility (Lande- und Mobilitätstest Anlage; LAMA) in Bremen. Using a first preliminary development model, the engineers are determining how robust the design of the approximately 25-kilogram rover must be to withstand an impact on the moon’s surface after a free fall of about 40 to 100 metres.
GREENBELT, Md. (NASA PR) — In an interplanetary faux pas, it appears some pieces of asteroid Vesta ended up on asteroid Bennu, according to observations from NASA’s OSIRIS-REx spacecraft. The new result sheds light on the intricate orbital dance of asteroids and on the violent origin of Bennu, which is a “rubble pile” asteroid that coalesced from the fragments of a massive collision.
TOKYO (JAXA PR) — The Japan Aerospace Exploration Agency (JAXA) and Japan Broadcasting Corporation (NHK) have decided to jointly develop a “Super Hi-Vision Camera” that is capable of filming 4K and 8K images in space for JAXA’s Martian Moons eXploration (MMX) mission.
This would be the first time in history that 8K ultra high definition images of Mars and its moons are taken in proximity. By combining the actual flight data of the MMX spacecraft and the images taken by the Super Hi-Vision Camera, the exploration of the MMX spacecraft around Mars and its moons (the Martian system), 300 million kilometers from the Earth, will be recreated.
