I wonder how this mission compares in scale to the JAXA Hayabusa comet interceptor done twenty years ago.

4 ton launch mass, so 8x mass increase against Og Hayabusa probe(510kg). About 5.4x Satrlink V2 mini sats.

The OG Hayabusa was tiny as it was on the M-V 3-stage all-solid launcher with just 1.85t to LEO of max payload. This one was on H3-24L with up to 16t to LEO(91% of an F9 ASDS) so it's bigger accordingly.
