L2 Certified¶
This rocket, named SIPSIK after the beloved Estonian cartoon character, achieved Tripoli L2 certification on 22 February 2026 at Enköping, Sweden, flying on an AeroTech J350 with dual deployment recovery via CATS Vega.
L1 certification was achieved one month earlier on 24 January 2026 at the same location.
The Story Behind Sipsik¶
The blue rocket connects to Estonian children's culture: in the Sipsik cartoon, a girl named Anu and her brother Mart build a cardboard rocket hoping to send their toy Sipsik to the moon. This rocket teaches my daughters Liza (5) and Elsa (2) how we actually send rockets to the sky.
