Small rocket projects

Ukrainian project “MARKS” of a small reusable rocket: 80 kg to SSO with declared cost $300 thousand per launch ($3750 per kg). As far as I understand, the project does not yet have funding and is a purely theoretical study.

Russian project expendable launch vehicle «Taymur» from «Lin Industrial» company: up to 147 kg to SSO with cost $25 000 per 1 kg. They have long been trying to implement this project, but the lack of reliable investors hinders them. I don’t think that they will eventually manage to get to the launches.
