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.
HOUSTON (NASA PR) — The International Space Station, a microgravity laboratory orbiting Earth at 17,500 miles per hour, has hosted a variety of scientific research for nearly 20 years. Some of that research continues for months and even years.
MOFFETT FIELD, Calif. (NASA PR) — For many of us, it’s OK to feel a little sleepy at your desk after lunch. But for people with jobs where it’s critical to be alert and able to think quickly and clearly, feeling fatigued from sleep loss, jet lag, shift work or waking up groggy can be a problem.
The Fatigue Countermeasures Lab at NASA’s Ames Research Center, in California’s Silicon Valley, studies the way fatigue affects people with complex tasks to perform. The realms for these tasks can be as diverse as aviation and spaceflight, NASA space mission operations, military settings and operating self-driving cars.
WASHINGTON (NASA PR) — NASA has selected the first two scientific investigations to fly aboard the Gateway, an orbital outpost which will support Artemis lunar operations while demonstrating the technologies necessary to conduct a historic human mission to Mars. The instruments selected for Gateway will observe space weather and monitor the Sun’s radiation environment.
Martian Moons EXploration (MMX) mission to explore moons, return soil sample from Phobos.
TOKYO (JAXA Program Update) — This week (19 February 2020), the MMX mission transitioned to become a JAXA Project: an official step in mission development authorised by the Japanese government. The mission was previously in the Pre-Project phase, where the focus was on research and analysis, such as simulating landings to improve spacecraft design. The focus will now move onto the development of mission hardware and software.
TOKYO, February 12, 2020 (Astroscale PR) – Astroscale Holdings Inc. (“Astroscale”), the market-leader in developing technology and services to remove space debris and secure long-term orbital sustainability, today announced it has been selected as the commercial partner for Phase I of the Japan Aerospace Exploration Agency’s (JAXA) first debris removal project, a groundbreaking step by Japan to commercialize space debris removal.
TOKYO (JAXA PR) — Japan Aerospace Exploration Agency (JAXA) announced that its Super Low Altitude Test Satellite “TSUBAME” (SLATS) was registered by the Guinness World Records (*1) as having achieved the “lowest altitude by an Earth observation satellite in orbit.”
TOKYO (JAXA PR) — Japan Aerospace Exploration Agency (JAXA) has selected, following public solicitation, and signed an agreement with Space BD Inc. who provides private companies and universities with piggyback launch opportunities for their small satellites when JAXA launches its own satellites using H-IIA and H3 launch vehicles.
LUXEMBOURG, December 13, 2019 (LSA PR) – The Luxembourg Space Agency today announced that Dr. Junichiro Kawaguchi, Senior Fellow at the Japan Aerospace Exploration Agency (JAXA) will be joining the Advisory Board of the SpaceResources.lu initiative.
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.
The sooner NASA can decide the future of the International Space Station (ISS), the easier it will be for the space agency to pursue its Artemis program to return astronauts to the moon by 2020, according to a new report from its Office of Inspector General (OIG).
“Whether NASA decides to extend, increase commercialization of, or retire the ISS, the timing of each of these decisions has a cascading effect on the funding available to support space flight operations in low Earth orbit, ambitions for establishing a permanent presence on the Moon, and ultimately sending humans to Mars,” the report stated.
TOKYO (JAXA PR) — Bascule Inc. (Representative Director & President: Masayoshi Boku), SKY Perfect JSAT Corporation (Representative Director, President & Chief Executive Officer: Eiichi Yonekura), and the Japan Aerospace Exploration Agency (JAXA) (President: Hiroshi Yamakawa) announced the launch of activities to establish a studio in the International Space Station (ISS) to generate the “space media business.”
HOUSTON (NASA PR) — The 19th SpaceX Commercial Resupply Services (CRS-19) contract mission for NASA carries a variety of cutting-edge scientific experiments to the International Space Station. The Dragon cargo spacecraft blasts off from Cape Canaveral Air Force Station in Florida on a Falcon 9 rocket no earlier than Dec. 4, 2019.
Its payloads include investigations studying malting barley in microgravity, the spread of fire and bone and muscle loss, which will be added to the dozens of research projects already under way aboard the microgravity lab.
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.
