Summary
IKONOS 2, also known as Ikonos, is an Earth observation satellite with NORAD identifier 25919 and OBJECT_ID 1999-051A. Launched on September 24, 1999, from the AFWTR SLC6 pad using the Athena-2 launch vehicle, this US-built spacecraft was manufactured by LMMS (Lockheed Martin Missiles and Space). The satellite has a box-like shape with a pan extension, measuring approximately 2 meters in length and diameter of 1.5 meters. It weighs 726 kilograms at launch and 688 kilograms dry. IKONOS 2 is equipped with three deployable fixed solar arrays and batteries for power generation. Its mission is to conduct Earth observation with a design lifetime of 7 years, though it achieved an operational lifespan of 15 years. The satellite has an RCS (Reflective Cross Section) value of 3.873. Owned by SIMG (Space Imaging), IKONOS 2's payload consists of its namesake imaging system designed for high-resolution Earth observation.
