News in 2010 Japanese page>> MMO Test (2009/11～2010) The solar illumination around the mercury will be 10 times of that around of the earth. The orbiter must tolerate the severe thermal environment. We performed various thermal vacuum tests using the Thermal Test Model (TTM) and successfully acquired data which are used for the thermal design of the flight model. 10 Solar Constant thermal balance test (5-16th/10/2010) at ESA 5 to 16 October 2010, 10 Solar Constant thermal balance test was done in the space chamber at European Space Center (ESA), the Netherlands. IR Thermal Balance Test (18-27th/2/2010) at Sagamihara 18 to 27 February 2010, IR thermal balance test was done in the space chamber at Sagamihara Campus, JAXA. 1 Solar Constant Thermal Balance test (26th/11/2009-3rd/12/2009) at Tsukuba 26 November to 3 December 2009, 1 Solar Constant thermal balance test was done in the space chamber at Tsukuba Space Center, JAXA.

BepiColombo, a cooperative mission by Japan Aerospace Exploration Agency (JAXA) / Institute of Space and Astronautical Science (ISAS) and European Space Agency (ESA), will explore Mercury, the planet closest to the Sun. ISAS/JAXA is building one of the main spacecraft, the Mercury Magnetospheric Orbiter (MMO), and ESA will contribute the other, the Mercury Planetary Orbiter (MPO).
