Hinode
Hinode (Japaneseひので; Sunrise ) is a space telescope that was developed by the Japanese space agency JAXA, with the participation of ESA, the British research organization PPARC and the Marshall Space Flight Center of NASA, first under the name SOLAR -B. With the satellite, the interactions will be studied between the magnetic field of the Sun and the solar corona. Hinode is the successor mission of the satellite Yohkoh ( Solar -A), which operated between 1991 and 2001.
The launch of Hinode was with a Japanese carrier rocket of the type MV on 22 September 2006 at 21:36 UTC clock from Uchinoura Space Center on the southern tip of the island of Kyushu. Hinode was the last payload of this rocket type, as the production of MV was discontinued after this start. The 900 kg satellite was put into a 280 × 686 km high orbit transition, which should be corrected in the weeks after the start of satellite 's thrusters to a 600 km high in sun -synchronous orbit. After starting SOLAR -B was called Hinode. The mission is designed for three years.
In February / March 2007 Hinode delivered the first pictures in X-rays show the complicated magnetic fields in the solar corona. Through these recordings was the theory that high-energy particles produced by such processes, are confirmed.
Technology
For this purpose, three instruments are set up essentially of:
- SOT = Solar Optical Telescope
- XRT = X- Ray Telescope
- EIS EUV Imaging Spectrometer
The photographs and measurements of all three instruments into a common signal processor to a total signal, but also provided individually.
Specifications:
- Mass: 900 kg
- Size: 1.6 × 1.6 × 4.0 m
- Length of the solar panel: 10 m
- Orbit: 600 km circular orbit ( sun-synchronous )
