Summary
RHESSI, also known as 2002-004A, is a solar observatory satellite operated by GSFC and manufactured by SPA. It was launched on February 5, 2002, from the ERAS launch site using a Pegasus XL launch vehicle from launch pad RW30/12. The spacecraft measures 2.2 meters in length with a diameter of 1.1 meters and spans 5.7 meters, featuring a configuration described as SA-200B (modified), spin-stabilized. It has a dry mass of 304 kilograms and is equipped with an X-ray and gamma-ray imaging spectrometer as its main equipment payload, known as HESSI. The satellite's power supply consists of four deployable fixed solar arrays and batteries. Its shape is characterized by a combination of cylindrical, box-like, and panel elements. RHESSI operates as part of the US space program for observing solar phenomena.
