Proton space rocket with 3 GLONASS sat's launched.

MOSCOW, March 2 (Itar-Tass) - A Proton-M carrier rocket with three satellites of the global navigatin system GLONASS blasted off from Baikonur cosmodrome on Tuesday.

Spokesman of Russia's Space Defence Forces, Lieutenant Colonel Alexei
Zolotukhin, has told Itar-Tass, "The launch of the Proton rocket with a DM
acceleration unit and three spacecraft of the Glonass-M type was effected
at 00:19, Moscow time".

.France, RF in "exclusive talks" on 4 Mistral ships.

PARIS, March 2 (Itar-Tass) -- France and Russia are involved in
"exclusive talks" on a possible purchase by Moscow of four French
Mistral-type helicopter carriers, French President Nicolas Sarkozy said at
a joint press conference with Russian President Dmitry Medvedev at the
Elysee Palace on Monday.
"France and Russia are beginning exclusive talks today for four
ships," Sarkozy said. He pointed out that the first of them would be built
at the famous French shipyard at Saint Nazaire on the Atlantic coast.
Nevertheless Sarkozy did not rule it out that a second ship might be also
built at the same shipyard. "Two and two was a reasonable agreement," he
remarked, implying that two Mistral-type ships will come off the assembly
lines in France and another two in Russia.
The French President emphasized that he referred to the delivery of
the ships "without military equipment".
"France recently returned to the NATO Joint Command (structure).
However, we have (also) got to respond (together with Russia) to common
challenges, such as, for example, terrorism," Sarkozy said. "Instead of
working against each other, it is better to work together," the President
said. "The Cold War period is over," he recalled.
The Mistral is a multi-functional naval ship which is capable of
carrying helicopters, tanks or be used as a command center. The French
Navy currently has available two ships of this class -- Mistral and
Tanner. These are the largest ships after the aircraft carrier Charles de
Gaulle.

.Booster, sat's separate from Proton rocket.

MOSCOW, March 2 (Itar-Tass) - The orbital unit, consisting of the DM
booster and three satellites of the global positioning system GLONASS, has
successfully separated from the carrier rocket Proton-M and reached the
base line orbit.
Lieutenant Colonel Alexei Zolotukhin, spokesman of Russia's Space
Defence Forces, has told Itar-Tass, "At 00:20, the orbital unit separated
from the third stage of the carrier rocket that had blasted off from the
Baikonur cosmodrome at 00:19".
An official at the Federal Space Agency (Roscosmos) specified, "The
subsequent orbit-insertion of the three spacecraft of GLONASS-M type will
be effected resultant of two ignitions of the booster's sustainer engine.
Approximately three and a half hours after the rocket's liftoff, the
satellites will be successively separated from the orbital unit. The
insertion of each satellite into a pre-set point of the orbital plane will
be carried out through ignition of the propulsion plants of the
satellites". It will take 45 days to render them operational.
The DM booster, which was devised and made at the Space Rocket
Corporation Energia, is designed to insert spacecraft of various purposes
into high elliptical and high circular orbits (including stationary ones).
It has been operating in conjunction with the carrier rocket Proton since
1974. The sustainer engine of the booster is an oxygen-hydrocarbon one.
The spacecraft of the Glonass-M type were developed at the
Zheleznogorsk (Krasnoyarsk-26)-based OAO (public joint-stock company)
Reshetnev Satellite-Aided Information Systems on the strength of the same
design solutions as those for their predecessors -- the Glonass
satellites -- as well as on the basis of a common space platform of
hermetic sealing design.
The main changes in the GLONASS-M came to the modification of the
antenna feeder device, an extension of the period of active functioning up
to seven years (whereas Glonass satellites had a parameter of 3-4.5
years), and the introduction of the second navigation frequency for civil
users. The Glonass-M has been in operation since December 2003. The weight
of one spacecraft is 1,415 kg.
The purpose of Tuesday's launch is to augment the orbital cluster of
the GLONASS system satellites. According to the Central Engineering
Research Institute, as of March 1 "The orbital cluster comprised 20
satellites, with 19 of them being used for end purpose, and one being
temporarily withdrawn from operation for maintenance".
At least 18 operating satellites are essential for the navigation
signal of the GLONASS system to be received continuously throughout
Russia's territory and 24 satellites are needed fir global coverage.
At a session of the Roscosnos Board last Saturday, Space Agency
Director Anatoly Perminov said the orbital cluster of the GLONASS system
would be augmented up to 27spacecraft this year.
Perminov said, "In the course of 2010 the orbital cluster of
satellites is to be enlarged up to 27 spacecraft, with at least 24 of them
to be used for end purpose. One of major tasks of the year is to complete
the manufacture and start of flying tests of a new-generation spacecraft,
the Glonass-K".
