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.
Vancouver Recommendations on Space Mining The Outer Space Institute April 20, 2020
Humanity is entering a new era of developing and utilizing Space that will likely include mining on the Moon, on near-Earth asteroids, and eventually on Mars. As part of this new era, a growing number of state and non-state actors are becoming capable of accessing and operating in Space.
TOKYO (JAXA PR) — On August 10, 2020, JAXA was informed that the Authorisation of Return of Overseas-Launched Space Object (AROLSO) for the re-entry capsule from Hayabusa2 was issued by the Australian Government. The date of the issuance is August 6, 2020.
The Hayabusa2 re-entry capsule will return to Earth in South Australia on December 6, 2020 (Japan Time and Australian Time). The landing site will be the Woomera Prohibited Area. The issuance of the AROLSO gave a major step forward for the capsule recovery.
We will continue careful operation for return of Hayabusa2 and recovery of the capsule, and the operation status will be announced in a timely manner.
Comment from JAXA President, Hiroshi Yamakawa:
“The approval to carry out the re-entry and recovery operations of the Hayabusa2 return sample capsule is a significant milestone. We would like to express our sincere gratitude for the support of the Australian Government as well as multiple organizations in Australia for their cooperation.
“We will continue to prepare for the successful mission in December 2020 in close cooperation with the Australian Government.”
TOKYO (JAXA PR) — Dr. Hiroshi Yamakawa, President, the Japan Aerospace Exploration Agency (JAXA) and Dr. Megan Clark AC, Head, the Australian Space Agency (the Agency) released a joint statement dated July 14 2020. The statement acknowledges that the capsule of ‘Hayabusa2’ containing the asteroid samples will land in South Australia on December 6, 2020.
CANBERRA, 9 July 2020 (Australian Government PR) — The Australian Space Agency and the Japan Aerospace Exploration Agency (JAXA) have signed a Memorandum of Cooperation (MOC) signalling new opportunities to increase space collaboration between the two nations.
The signing took place at a bilateral meeting between the Agency and JAXA, and was later acknowledged at the Australia-Japan Virtual Leaders Meeting with Prime Minister Scott Morrison and Prime Minister Shinzō Abe.
NICE, France (ESA PR) — Queen guitarist and astrophysicist Brian May has teamed up with asteroid researchers to investigate striking similarities and a puzzling difference between separate bodies explored by space probes. The research team ran a supercomputer-based ‘fight club’ involving simulated large asteroid collisions to probe the objects’ likely origins. Their work is reported in Nature Communications.
TOKYO (JAXA PR) — New information about the surface and orbit of Ryugu has been uncovered from analyzing data obtained during touchdown and the global observations performed by the asteroid explorer, Hayabusa2. These findings have been published in the electronic version of the US scientific journal Science, on May 7, 2020 (May 8, JST: Morota et al, 2002). The paper was led by Associate Professor Tomokatsu Morota from the University of Tokyo and member of the Hayabusa2 science team.
TOKYO (JAXA PR) — The 2nd ion engine operation has begun. This is an important operation in the return journey of Hayabusa2 back to Earth. On May 12, 2020, the ion engine ignited at 07:00 (onboard time, JST) and was confirmed to be operating stably at 07:25 (ground time, JST).
Currently, only a single ion engine is operating as the spacecraft is far from the Sun, and receives a low level of solar power with which to operate the ion engines.
The 2nd ion engine operation will continue until around September this year. At the end of the operation, the spacecraft will be in an orbit that can deliver the capsule to Earth. After that—from October this year—we will perform precision guidance using the chemical thrusters (figure 1).
It is now only a short time before we return to Earth.
Infrared images show that Ryugu is almost entirely made up.
The asteroid was formed largely from fragments of a parent body that was shattered by impacts of highly porous material.
DLR scientists participate in the publication in the scientific journal Nature.
COLOGNE, Germany (DLR PR) — The Solar System formed approximately 4.5 billion years ago. Numerous fragments that bear witness to this early era orbit the Sun as asteroids. Around three-quarters of these are carbon-rich C-type asteroids, such as 162173 Ryugu, which was the target of the Japanese Hayabusa2 mission in 2018 and 2019. The spacecraft is currently on its return flight to Earth.
Numerous scientists, including planetary researchers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), intensively studied this cosmic ‘rubble pile’, which is almost one kilometre in diameter and can come close to Earth. Infrared images acquired by Hayabusa2 have now been published in the scientific journal Nature. They show that the asteroid consists almost entirely of highly porous material.
KOBE, Japan (Kobe University PR) — Analysis of the impact craters on Ryugu using the spacecraft Hayabusa 2’s remote sensing image data has illuminated the geological history of the Near-Earth asteroid.
A research group led by Assistant Professor Naoyuki Hirata of the Department of Planetology at Kobe University’s Graduate School of Science revealed 77 craters on Ryugu. Through analyzing the location patterns and characteristics of the craters, they determined that the asteroid’s eastern and western hemispheres were formed at different periods of time.
GREENBELT, Md. (NASA PR) — An international team has found sugars essential to life in meteorites. The new discovery adds to the growing list of biologically important compounds that have been found in meteorites, supporting the hypothesis that chemical reactions in asteroids – the parent bodies of many meteorites – can make some of life’s ingredients. If correct, meteorite bombardment on ancient Earth may have assisted the origin of life with a supply of life’s building blocks.
