... It?s needs solution satellite?s orientation problem for defining location of sources of ionospheric emissions above Earth?s surface with necessary accuracy. There is possibility to define orientation of photometric devices by using TV images of star background. The CCD TV camera is designed for recording of images of star sky, Earth? limb and adjoining part of Earth? surface to fix the orbit point coordinates during the measurements by FAGOT and SICH-F devices. ...
... New technique measures mass of exoplanets . ... Now, scientists at the Massachusetts Institute of Technology (MIT) have developed a new technique for determining the mass of exoplanets using only their transmission spectra dips in light as a planet passes in front of its star. ... To determine the mass of an exoplanet using transmission spectroscopy, de Wit relied on the effect that a planet s mass has on its atmosphere, as transmission spectra give information on a planet s atmospheric properties. ...
