Top 10 Spaceflight Missions 2026: NASA’s Lunar Mission Artemis II To JAXA’s Hayabusa2 Asteroid Torifune Flyby & More

This short film explores the special partnership between Australia and Japan to successfully bring #Hayabusa2 home, in what was a remarkable feat for space science.: https://www.youtube.com/watch?v=GKIfFh5hIUM

Last week, we opened a three year exhibit of a grain from asteroid Ryugu at the Australian Space Discovery Centre, home of the Australian Space Agency, in Adelaide 🛰️! JAXA’s #Hayabusa2 mission returned the sample capsule to the Woomera desert in 2020 (moderately) close to Adelaide, so this little grain came home!

"Overall, Ryugu isn’t just a rock; it’s a probe into the Solar System’s wet youth..."

Tomorrow (10/07) at 10:30am ACDT, #JAXA ISAS Director General Fujimoto Masaki will give a talk (online and on-site) about the #Hayabusa2 mission 🛰️, as a fragment of asteroid Ryugu is unveiled for display at the Australian Space Discovery Centre in Adelaide 🪨!
Adelaide is the nearest big city to Woomera, where the sample capsule from Hayabusa2 landed. So this little grain is coming back to its first Earth home!

Wenn Japans Sonde #Hayabusa2 fast größer als der Asteroid 1998-ky26 ist und das Teil mit Affenzahn rotiert, könnte eine Landung schwierig sein. Aber die Sonde ist eh in Missionsverlängerung unterweg.

Hayabusa2’s Final Target is 3 Times Smaller Than We Thought
It also spins twice as fast as previous estimates suggested. A spacecraft touchdown will be challenging, but not impossible.

Can Japan's #Hayabusa2 touchdown on asteroid 1998 KY26?
A new study that includes VLT observations reveals the mission’s target asteroid to be three times smaller and rotating much faster than previously thought.

The parent body of asteroid Ryugu appears to have harbored water in the form of ice for over a billion years, Japanese researchers have found, in a discovery that could reshape ideas on how the Earth got its oceans. https://www.japantimes.co.jp/news/2025/09/11/japan/science-health/ryugu-asteroids-water-earth/?utm_medium=Social&utm_source=mastodon #japan #sciencehealth #hayabusa2 #space #astronomy #asteroids #planets #ryugu

I chatted to Brendan O'Brien at the AstroPhiz podcast the other week, and together we relived JAXA's #Hayabusa2 asteroid exploration mission 🛰️, the ridiculously daring engineering of sample return ⚒️, the first results from an analysis that pokes at the start of our existence 🧪, my life as an asteroid courier 🥷, and a look towards the future as #JAXA heads out to bite a Martian moon! 🔭

A new edition of JAXA's #ISASNews newsletter has come out, sharing stories from the Institute of Space and Astronautical Science.
We put together short summaries in English! 🛰️ The first story is on results from the analysis of asteroid #Ryugu, brought home by the #Hayabusa2 mission.
And if these are tantalisingly epic, you can wrestle down the full stories (in Japanese) here: https://www.isas.jaxa.jp/outreach/isas_news/
