Soyuz 13 was a second test flight of the redesigned Soyuz capsule that first flew as
Soyuz 12. This particular spacecraft was further specially modified to carry a large camera for astrophysical observations.
Using this instrument, cosmonauts Valentin Lebedev and Pyotr Klimuk carried out
ultraviolet photography of stars and spectroscopic photography of the Earth.
Once again, the new Soyuz variant performed extremely well when on-board systems were tested.
