The Proton-M, (Протон-М) GRAU index 8K82M or 8K82KM, is an expendable Russian heavy-lift launch vehicle derived from the Soviet-developed Proton.It is built by Khrunichev, and launched from sites 81/24 and 200/39 at the Baikonur Cosmodrome in Kazakhstan.
With the Briz-M upper stage, the payload fairing diameter is 4.1 m (13.45 ft). [22] Proton launch vehicles and Briz-M upper stages are designed and built by Khrunichev State Research and Production Space Center (Khrunichev) in Moscow, the majority owner of International Launch Services (ILS).
As of 13 March 2023, rockets of the UR-500 / Proton family have accumulated 430 launches since 1965, 382 of which were successful, yielding an 88.8% success rate. For launches in a specific decade, see: List of Proton launches (1965–1969) List of Proton launches (1970–1979) List of Proton launches (1980–1989)
All launch vehicle propulsion systems employed to date have been chemical rockets falling into one of three main categories: Solid-propellant rockets or solid-fuel rockets have a motor that uses solid propellants , typically a mix of powdered fuel and oxidizer held together by a polymer binder and molded into the shape of a hollow cylinder.
A heavy-lift launch vehicle (HLV) is an orbital launch vehicle capable of lifting payloads between 20,000 to 50,000 kg (44,000 to 110,000 lb) ... Proton-M Russia ...
A Saturn V rocket, one of the most powerful operational launch vehicles to date. This article compares different orbital launcher families (launchers which are significantly different from other members of the same 'family' have separate entries).
Briz-M takes much less space on board the launch vehicle compared to its predecessor, the Block D upper stage, leaving freed volume for the cargo. [8] A Proton with a Briz-M can place a 4,385 kg satellite, such as an A2100AX , into a target orbit with an apogee of 35,786 km, a perigee of 7,030 km, and an inclination of 17.3°.
As of September 2015, 3 Proton-M/Blok DM-03 have been launched, of which 2 have failed. In the 2010 failure, the rocket was too heavy to reach orbit and reentered the atmosphere during a coast phase between the end of third stage flight and the beginning of the Blok DM-03's first burn, whilst the 2013 flight failed after the rocket went out of ...
