Abstract: The present invention relates to a method and a system for measuring mass under a microgravity environment. The system for measuring mass under a microgravity environment comprises: an electronic magnet; a platform where a sample to be measured is fixated, which includes a first permanent magnet at a position corresponding to the electronic magnet, and which horizontally moves along a moving guide by repulsive power of the electronic magnet and the first permanent magnet; a position sensor which senses that the platform passes a preset specific position; an actuating device which turns on/off the actuation of the electronic magnet; and a central controller which calculates current applied to move the electronic magnet to the specific position based on voltage received from the actuating device, and calculates the mass of the sample by substituting the current into below: m_t=I_t/I_s(m_s+m_p)-m_p In the above , m_t indicates the mass of the sample, I_s indicates the current applied to the electronic magnet when measuring standard mass, m_s indicates the standard mass, and m_p indicates platform mass.

Abstract: A mass measuring system and a method for the same are provided to increase accuracy and efficiency of space experiments by measuring exact mass of animal and plant rapidly and accurately. In a mass measuring system, a standard mass(25) is installed with a diameter different from a rotation center of an object(10) to be measured. A rotation driving device rotates the object to be measured and the standard mass. First and second load cells(21) are connected to the object to be measured and the standard mass to output a sensing signal by sensing centrifugal force due to a rotational movement. The diameters of the first and the second load cells are different from each other from the rotation center of the rotation driving device. A pair of signal process devices(30,31) calculate mass of the object to be measured by using the centrifugal force detected by the first load cell fixed thereto the object and the second load cell fixed thereto the standard mass and the centrifugal force detected by the first load cell fixed thereto the standard mass and the second load cell fixed thereto the object to be measured.

Abstract: The present invention relates to a mass measuring apparatus using impulse under a micro-gravity environment that can accurately and precisely measure the mass using the impulse under the micro-gravity environment. The mass measuring apparatus includes a driving unit; a common acceleration unit accelerated by the driving unit and receiving a target sample, of which the mass is measured, and a standard sample of which the mass is previously known; a first detector spaced apart from the common acceleration unit in a fixed state to detect the impulse of the target sample; a second detector spaced apart from the common acceleration unit in a fixed state to detect the impulse of the standard sample; and a control unit for computing the mass of the target sample by the impulse detected by the first and second detectors and the mass of the standard sample.
