On June 13 --"Hayabusa Day"-- the PPTD-TM1B operation for Hayabusa2 was completed safely. It has not yet been decided if the second touchdown (PPTD) will be performed, but all the important operations prior to PPTD are finished and we will continue to consider the operation.

[PPTD-TM1B] When we run in shifts for a 24-hour operation, the corner of the corridor outside the control room is stocked with coffee and sweets which we call the "Snack Otohime". This photo is today's "Snack Otohime"!
