SERPENS is Brazilian 3U Cubesat built by the SERPENS (Sistema Espacial para Realização de Pesquisa e Experimentos com Nanossatélites) university consortium.

The satellite features a transponder to test VHF and S-band communications for store and forward messaging, a UHF transponder fully compatible with the HUMSAT store and forward messaging system and a pulsed plasma thruster (PPT) built by Mars Space Ltd. and Clyde Space, both from U.K.

The satellite was delivered to the ISS by the HTV 5 cargo craft. It was deployed on 17 September 2015.

On 27 March 2016 SERPENS reentered the atmosphere.
