Summary
PHOBOS 1 was launched on July 7, 1988, from the Tyuratam Space Center (TYMSC) using a Proton-K/D-2 launch vehicle from Launch Pad LC200/39. The spacecraft, also known as Fobos-1, is classified under the Fobos bus type and was manufactured by NPOL for IKI/BABTS. PHOBOS 1's mission included orbiting Mars with the capability of deploying one or two Phobos landers. It measured 4 meters in length, 3.5 meters in diameter, and had a span of 12 meters when its solar arrays were deployed. The satellite weighed 2420 kg at launch and was powered by deployable solar arrays and batteries. Its shape is described as "Irr + 2 Pan," indicating an irregular body with two panoramic components. PHOBOS 1's mission ended shortly after launch due to a command sequence error, resulting in loss of contact on September 2, 1988.
