Lancement Soyouz-2.1b / Persona - juillet 2008

28 years ago, on 18 March, 1980, with the preparation for the starting of rocket - carrier "Vostok-2M» on the launcher №ya of the spaceport Of plesetsk, as a result of the explosion of rocket perished 48 soldiers, and more than 40 obtained injuries.

Persona optical reconnaissance satellite. Soyuz-2.1b launcher, from Plesetsk, the /third quarter of 2007/. This will be a double maiden flight - the first Soyuz-2.1b flight from Plesetsk (it flew from Baykonur before) and the first Persona spacecraft. The spacecraft was reported to weight about seven tonnes. It will carry a new telescope/sensor package, that is being developed at LOMO.

TsSKB-Progress Director General Alexander Kirilin called the launch “a serious achievement of the military industry.” He noted that “the booster Soyuz-2 is equipped with a new engine.” According to him, “The satellite has five years of service life on the orbit.” “The functional capabilities of this spacecraft are very high,” Kirilin told reporters on Saturday. “The satellite will operate in the distant probing
regime,” the director general said.

A ma connaissance (de tête) ce doit être le
second (le premier une soyouz 2.1a)

The 2-1b achieves this with the new RD-124 third stage engine that
uses kerosene that has a low tar level, which would require new
infrastructure.
"For the 2-1b it would take two years (to install the
infrastructure) from a decision, which I think will come soon. We could
still launch 2-1b from 2009," says European Space Agency Soyuz
programme manager Harald Arend.
However the new infrastructure for the 2-1b will require monies in addition to the existing 400 million Euro cost.
The 2-1b's use of a different kerosene to the 2-1a the launch
complex requires additional propellant handling equipment, such as
storage tanks and pipes. There is also a need with the RD-124 for more
helium handling capacity.
The 2-1a has the RD-110 third stage engine and it uses a higher tar
content kerosene for that stage and the first and second stage engines.
The 2-1b also uses this higher tar kerosene for its first and second
stage engines.
