LabSat

LabSat is the product of institutions such as Wroclaw University of Science and Technology, Wrocław University of Environmental and Life Sciences, Wroclaw Medical University, and Ludwik Hirszfeld Institute of immunology and Experimental Therapy. SatRevolution provided a platform in the form of a 3U CubeSat bus for the purpose of conducting biological experiments. LabSat will launch into orbit on December 2020 on SpaceX Falcon 9 rocket.
