The Small Carry-on Impactor (SCI) is a small drop-off explosively formed penetrator, consisting of a 2.5 kilogram (5.5 lb) copper projectile and a 4.5 kilogram (10 lb) shaped charge.[15] It will be dropped off Hayabusa2; the low gravity leaves the spacecraft enough time to maneuver to the opposite side of the asteroid. -Haybusa2 - wikipedia

Sounds like Haybusa was not risky enough for JAXA, lol.

Reading the link, appears to be a suborbital liquid fueled (ethanol/LOX) sounding rocket with a payload capacity of 20kg, powered by a 12kn pressure fed engine, payload section recoverable, designed to facilitate launches within 3 months of applying. I'm reading the user's guide, I will edit this post if I find anything else of note.

EDIT:

They are lending out scale models, apparently.

 

Height: 9.9m

Diameter: 0.502m

Wet mass: 1t

Dry mass: 0.7t (wow, pretty bad mass fraction)

The engine gimbals, and roll control is provided by cold gas thrusters, which may or may not be fed from the same helium that pressurizes the tanks.

Maximum planned acceleration: 5g

4 minutes of microgravity, but only about 2.5 of that is very high quality microgravity.

Payload must fit into a 300cm cube.

About half of the cylindrical section of the rocket can be advertised on.

They can mount onboard cameras.

 

No word on price, though. I'll try my luck with their email, but the odds I'll get a response are very low.
