Payload configuation of MASER-12, launch and recovery. A. Payload configuration of the MASER-12 sounding rocket. MASER-12 consists of a VSB-30 motor (S-30 solid rocket stage engine with a S-31 second stage engine) and of the payload. MASER-12 hosted five experiments and provided six minutes microgravity. The experiment of the study was performed in the module “Biology In Microgravity“(BIM-2) where the LAU (“Late Access Unit“) containing the isolated cells was installed shortly before the launch. (Pictures were kindly provided by SSC). B. MASER-12 was launched on February 13th 2012, 09:32 am, from the ESRANGE Space Centre near Kiruna, Sweden, north of the Arctic circle). C. Work with BIM-2 (Biology In Microgravity-2) module at the landing spot. The recovery of the LAU was successful. The module was switched off, by access from the umbilical connector, at 1 hour 20 minutes after lift-off. D. The Late Access Unit (LAU) was transported back in a dedicated helicopter from the landing spot.
