To avoid dusting the asteroid grain into oblivion, I carefully open the protective carry case and rotated the sample container 90 degrees before very very gently placing it flat inside one of the bins for the x-ray scanner.
The airport assistant promptly picked up the bin and plopped it with a bump on the conveyer belt π
I wondered if I could forego the people scanner and go through as baggage, curled in one of the bins, with the asteroid grains cradled to my belly.
Worried that no sane person would believe my story about carrying a rock from outer space, I had done something I had never done before in all my six years at the space agency.
I was wearing my official JAXA pin badge.
This small rectangular pin is given only to employees, and I was told I would have to return it when I left the agency or retired. Since it looked imminently losable, I'd hidden it in my desk.
But now (after some searching), it was pinned to the lapel of my Hayabusa2 jacket.
