Abstract:
It is important to conduct long-term continuous observations for studies on time-dependent events in the planetary atmospheres and plasmaspheres. The FUJIN project aims at continuous observations of planets using a telescope lifted by a balloon in the polar stratosphere. The FUJIN-2 will be launched at ESRANGE in Kiruna, Sweden in the window from June to August in 2016. The gondola will be recovered in Scandinavia after two or three weeks flight. The main target of the FUJIN-mission was Venus previously. But since the outline of Venus changes its phase, it is hard for us to plan the test using balloon which choose the observation term to free. We decide to mainly observe Jupiter for same conditions over one year without the term of conjunction. We will observe the haze in the Jupiter’s polar using the most deep absorption band of methane in 890nm, visual-infrared region, and we will get the parameters which decide that the wave is Rossby-Wave to get the Jupiter’s background wind. And we will observe Mercury’s sodium atmosphere and tail as an optional observation as an option.
