Hinode (

Japan Aerospace Exploration Agency Solar mission with United States and United Kingdom collaboration. It is the follow-up to the Yohkoh (Solar-A) mission and it was launched on the final flight of the M-V rocket from Uchinoura Space Center, Japan on 22 September 2006 at 21:36 UTC (23 September, 06:36 JST). Initial orbit was perigee height 280 km, apogee height 686 km, inclination 98.3 degrees. Then the satellite maneuvered to the quasi-circular Sun-synchronous orbit over the day/night terminator
, which allows near-continuous observation of the Sun. On 28 October 2006, the probe's instruments captured their first images.

The data from Hinode are being downloaded to the

Svalsat station, operated by Kongsberg a few kilometres west of Longyearbyen, Svalbard. From there, data is transmitted by Telenor through a fibre-optic network to mainland Norway at Harstad
, and on to data users in North America, Europe and Japan.

Mission

Hinode was planned as a three-year mission to explore the magnetic fields of the Sun. It consists of a coordinated set of optical,

UK.[3] NASA, the space agency of the United States, was involved with three science instrument components: the Focal Plane Package (FPP), the X-Ray Telescope (XRT), and the Extreme Ultraviolet Imaging Spectrometer (EIS) and shares operations support for science planning and instrument command generation.[4]

As of March 2024[update], the operation is planned to continue until 2033.[5]

Instruments

2012 Venus transit

Hinode carries three main instruments to study the Sun.

SOT (Solar Optical Telescope)

A 0.5 meter Gregorian

dopplergram images of the solar surface; and the Spectropolarimeter (SP) which produces the most sensitive vector magnetograph
maps of the photosphere to date.

The FPP also includes a Correlation Tracker (CT) which locks onto

arcsecond. The spatial resolution of the SOT is a factor of 5 improvement over previous space-based solar telescopes (e.g., the MDI instrument on the SOHO
).

XRT (X-ray Telescope)

A modified Wolter I telescope design that uses grazing incidence optics to image the

NAOJ and JAXA
.

EIS (Extreme-Ultraviolet Imaging Spectrometer)

A normal incidence extreme ultraviolet (EUV)

solar corona
