The "Strange Days" of Phobos-2: in Mars' orbit (2)

The last successful Soviet space probe, Phobos-2, arrived in Martian orbit on January 30, 1989. It carried an optical-mechanical linear camera that operated simultaneously in red/near-infrared light (600 - 950 nnmts) and far thermal infrared (8,5 - 12 ì), using a cryogenically cooled detector. Four pairs of panoramas were received.
The elongated horizontal smudge seen in some images is the shadow of Phobos, traveling in nearly the same orbit as the spacecraft.
