 Planned orbital configuration of DOS-2 | |
DOS-2 was a space station, launched as part of the Salyut programme, which was lost in a launch failure on 29 July 1972, when the failure of the second stage of its Proton-K launch vehicle prevented the station from achieving orbit.[3][4] It instead fell into the Pacific Ocean. The station, which would have been given the designation Salyut 2 had it reached orbit, was structurally identical to Salyut 1, as it had been assembled as a backup unit for that station.[1] Four teams of cosmonauts were formed to crew the station, of which two would have flown:[1]
- Alexei Leonov and Valeri Kubasov
- Vasily Lazarev and Oleg Makarov
- Aleksei Gubarev and Georgi Grechko
- Pyotr Klimuk and Vitaly Sevastyanov
Whilst Salyut 1 had been attempted to be visited by two three-person crews (Soyuz 10 and Soyuz 11), following modifications to the Soyuz 7KT-OK spacecraft (resulting in the new model Soyuz 7K-T) following the deaths of the crew of Soyuz 11, the spacecraft could only carry two cosmonauts, thus DOS-2 would have had two crews of two. Following the loss of the station, the crews were transferred to the DOS-3 programme.[1]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
