"The power on campus is out. The buildings are all locked down and there's no access."

"There's a 4.56 billion year old asteroid fragment in my office that needs to be on an international flight tonight."

This trip was not starting smoothly 🤨

With the launch looming in approximately one year from now, messages (hopefully predominately) of good luck and excitement were added to cloths depicting the Martian Moons eXploration (MMX) spacecraft 🛰️. I think we had four filled by the end of the open day!

20 years ago, Hayabusa collected a sample from asteroid Itokawa. Damaged by a huge solar flare, the spacecraft still returned the sample capsule to Earth in 2010. With no way to save the spacecraft, JAXA rotated Hayabusa so that its cameras could see Earth before burning up in the atmosphere 🛰️.

It’s our open day at ISAS. A terrifying prospect, and it’s pouring with rain. But this is a half-scale model of the Martian Moons eXploration (MMX) spacecraft. HALF SCALE. It’s the biggest spacecraft we’ve ever built 😳
A view from above of the lobby at the Sagamihara campus for ISAS JAXA. The space is dominated by a large spacecraft model, covered in gold and flanked by large solar panels. Even at half size, it towers cover the visitors.

It was quite sweet. Not bad, but probably not a regular go-to!

Went to a K-pop concert for NCT DREAM which had been recorded in 3D for #VR! It was hosted on Horizons, so you could go with friends (in this case, @futuremeetings.bsky.social buddies!) and while it’s obviously different to a billion people concert, it’s a front row seat and great social experience!
Snap from the concert. On the stage immediately in front of my virtual seat is the seven-member boy band NCT DREAM, dancing to one of their numbers. Another front row seat view. The band are silhouetted against the stage lights as the song ends.

A seasonable sweet potato milk drink is a very Japan’s take on pumpkin spice 🍠🥛
My hand holding a plastic bottle containing a yellow drink. The label says (in Japanese) that this is a sweet potatoe flavoured milk drink. There is a picture of a sweet potato to enforce this image!

It’s good to be home 🙂 #NorahNeko
A calico cat is lying on my lap while I’m seated at my desk at home. She looks relaxed and glad to be back too!

And then we’re back and Australia could have been a dream… but there are hints 😂

KANGANAUT! 👩‍🚀🦘That is all.

JAXA work closely with the ASA (Australian Space Agency) for the capsule delivery, so I think that the engagement would be from the ASA.

Time to eat the local fauna 🦘

The return of the Hayabusa2 sample capsule to Australia, and a wonderfully personal account of the mission, was written by @jacksonwryan.com. Fujimoto Masaki led the recovery team, and he insisted that JAXA allocate a Ryugu sample grain to be displayed in Adelaide as soon as they requested.

Adelaide is the nearest big city to the Woomera desert, where the Hayabusa2 sample capsule landed in December 2020. So this tiny grain is coming back to its first home 🤩

Discussions are now in full-swing to land the capsule for the Martian Moons eXploration (MMX) mission in Woomera in 2031 ☄️

A JAXA masu (square wooden box used for drinking sake) that were themed for the #IAC2025 this year in Sydney!
A square wooden box with the JAXA logo on one side and the shape of Australia burned into the inside base reading “IAC2025 Sydney”.

Unfortunately, I’m visiting friends in the blue mountains tomorrow and then I have to head to Adelaide for the new asteroid grain exhibit there 🙁

It’s public day at the # IAC2025. A small child, dressed in an astronaut costume, rushed the JAXA booth and hugged the model H3 rocket which wobbled dangerously.

It’s six minutes past 9. Pray for me.
