    For a brief period it seems like we went from Space Race to Space Disgrace.
    Yes, the USA did have the good grace to not land radioactive waste here. And, it was good for tourism. Parts of Skylab are still on display in the Esperance museum on the southern coast of Western Australia. About 700 km south east of my home in Perth.

    That's the way to pick up the pieces. I certainly can't fault the Australian sense of good humour when it came to dealing with the unfortunate aftermath of Skylab.

    Another report of the arrival of asteroid dust from Hayabusa-2.

    https://www.spacedaily.com/reports/A...Earth_999.html

    In a streak of light across the night sky, samples collected from a distant asteroid arrived on Earth Sunday after being dropped off by Japanese space probe Hayabusa-2.

    Scientists hope the precious samples, which are expected to amount to no more than 0.1 grams of material, could help shed light on the origin of life and the formation of the universe.

    The capsule carrying samples entered the atmosphere just before 2:30 am Japan time (1730 GMT Saturday), creating a shooting-star-like fireball as it entered Earth's atmosphere en route to a landing site in Australia.

    "Six years and it has finally come back to Earth," an official narrating a live broadcast of the arrival said, as images showed officials from Japan's space agency JAXA cheering and pumping their fists in excitement.

    Or maybe the crotch protection is for kangaroos? I hear they pack a nasty kick.

    Looks a bit like a suit you’d wear to defuse a bomb. That makes me wonder if the capsule contained pyrotechnic devices and the concern was they might ignite.

    With zero information, I'd guess that the parachute release system could include pyrotechnics, so you make a good point.

    "Hayabusa2 capsule taken to JAXA lab"

    https://www3.nhk.or.jp/nhkworld/en/news/20201208_27/

    A capsule released by the Japan Aerospace Exploration Agency's space probe Hayabusa2 arrived at a lab near Tokyo, Japan on Tuesday. Officials held a news conference during which they thanked the public for warmly welcoming back the capsule.

    The capsule is believed to contain samples from the Ryugu asteroid. It was retrieved after landing in an Australian desert on Sunday and arrived at Haneda Airport in Tokyo on Tuesday morning.

    Tsuda Yuichi, the project manager of Hayabusa2, said he was touched when he realized that the capsule had traveled more than 5 billion kilometers.

    "Black 'sand-like' asteroid dust found in box from Japan probe"

    https://www.spacedaily.com/afp/20121....4bxchcxz.html

    Black sandy dust found in a capsule brought to Earth by a Japanese space probe is from the distant asteroid Ryugu, scientists confirmed after opening it on Monday.
    The discovery comes a week after the Hayabusa-2 probe dropped off its capsule, which entered the atmosphere in a streak of light before landing in the Australian desert and then being transported to Japan.

    The Japanese space agency (JAXA) released a picture of a small deposit of sooty material inside the metal box -- a first glimpse at the results of an unprecedented six-year mission for the unmanned probe.

    "Asteroid samples leave Japan scientists 'speechless'"

    https://www.spacedaily.com/afp/20121....cv86l49k.html

    Scientists in Japan said Tuesday they were left "speechless" when they saw how much asteroid dust was inside a capsule delivered by the Hayabusa-2 space probe in an unprecedented mission.

    The Japanese probe collected surface dust and pristine material last year from the asteroid Ryugu, around 300 million kilometres (200 million miles) away, during two daring phases of its six-year mission.

    "Hayabusa2 Team Honored with Prime Minister's Award"

    https://www.nippon.com/en/news/yjj2020121700917/

    The Japanese government presented the prime minister's award to the project team of the Hayabusa2 unmanned asteroid probe of the Japan Aerospace Exploration Agency, or JAXA, on Thursday.

    In a ceremony held at the prime minister's office, Prime Minister Yoshihide Suga praised a number of the spacecraft's world-first achievements, including two landings on asteroid Ryugu.

    JAXA President Hiroshi Yamakawa said, "It would be an honor if we were able to contribute to cheering up Japan."

    "Hagiuda: Hayabusa2 capsule had 5.4g of samples" Well done Japan

    https://www3.nhk.or.jp/nhkworld/en/news/20201218_25/

    Science and technology minister Hagiuda Koichi says a capsule brought back by Japan's Hayabusa2 asteroid probe contained at least 5.4 grams of samples. That's more than 50 times the targeted volume.

    Hagiuda spoke to reporters on Friday after observing the ongoing work to analyze the samples by the Japan Aerospace Exploration Agency, or JAXA.

    On December 10, 2020 (Hawai'i Standard Time), the Subaru Telescope imaged the small asteroid 1998 KY26, the target of Hayabusa2's extended mission. The positional data for 1998 KY26 collected during the observations will be used to more accurately determine the orbital elements of this object. Operated by the Japan Aerospace Exploration Agency (JAXA), the asteroid explorer Hayabusa2 delivered a reentry capsule to Earth containing samples from the asteroid (162173) Ryugu on December 6 (Japan Standard Time). After this drop-off, Hayabusa2 set out again, this time for the extended mission utilizing its remaining fuel. In this extended mission, Hayabsa2 is supposed to approach and observe its next target, the small asteroid 1998 KY26. This asteroid is predicted to approach to within 0.47 AU of Earth in mid to late December 2020, giving us a rare opportunity that comes only once every three and a half years. However, the diameter of 1998 KY26 is estimated to be no more than 30 meters, and thus its brightness is so dim that ground-based observations of the asteroid are difficult without a very large telescope.

    "Hayabusa2 capsule contains gravel"

    https://www3.nhk.or.jp/nhkworld/en/news/20201224_16/

    Scientists at the Japan Aerospace Exploration Agency, or JAXA, have been working to open the storage device of a capsule released by Hayabusa2.

    The capsule, which contains samples from the remote asteroid Ryugu, landed in an Australian desert on December 6.

    At an online news conference on Thursday, JAXA scientists said they established there were a number of samples containing pieces of gravel measuring nearly one centimeter in size.

    The samples are believed to have been collected during the probe's second touchdown on Ryugu.

    Hmm, both sand and gravel. Just a little Portland Cement and future explorers could make concrete!

    It is more than that according to the latest information - "Soil from asteroid shows it has ingredients for creating life"

    http://www.asahi.com/ajw/articles/14375695

    The Ryugu asteroid's soil contains enough hydrogen atoms to make a large quantity of water and molecules of organic substances that can be ingredients for life, according to analysis of samples returned to Earth by the Hayabusa 2.
