    \textcolor{black}{Small satellite missions are disrupting the satellite industry in the recent
    years, by following a non-traditional-space approach with low cost, fast delivery, and innovation through the
    application of commercial electronics and materials revolution into space systems. However, there are still challenges
    that make the path for accessing space via a successful mission development difficult. In most of the cases a
    combination of the satellite's design, risk adoption and the space environment effects and qualification of the
    systems, impact the mission requirements, the satellite development schedule, and costs, as well as the operations. The
    space environment around the Earth remains a major concern as well as a dynamic field of study by itself, which requires a better
    understanding with a focus on space environment-to-satellite interaction process. Its comprehensive knowledge requires
    different input data, in order to provide a complete model of the small satellite systems behavior when operating in
    orbit. To provide such data for future missions, Kyushu Institute of Technology in partnership with Prairie View Texas
    A\&M University and the }}\textcolor{black}{Space Research \& Technology Institute of
    the }{\selectlanguage{english}{\textcolor{black}{ Bulgarian Academy of Sciences developed a small satellite mission
    called Ten-Koh, with the purpose, on one hand, to perform near-Earth science in a fast and low cost mission, and on the
    other to act as a testbed for space technology development. Ten-Koh satellite was launched into space onboard an H-2A
    rocket on October 29th, 2018, as a piggyback payload of the GOAT-2 launch from the Tanegashima space center in Japan.
    Ten-Koh satellite operates among its different payloads, a double Langmuir probe (DLP) system for plasma sheath
    characterization around a spinning spacecraft, with a settable bias voltage between -10 [V] to 10 [V] and a current
    capability measurement from 100 [pA] to 1 [uA]; a small 3-axis magnetometer instrument for measuring the Earth's
    magnetic field variations in the range from -0.2 to 0.2 [mT], with a resolution of 7.63 [nT]; a charged particle
    detector (CPD) intended for observing electrons, protons and ions in the MeV range; a set of 3 new material samples
    made of LATS and CFRP for measuring the change in their mechanical properties when exposed to the space environment.
    The design, tests, preliminary results and lessons learned from the mission are presented.}}
