Today, 23 Dec 2014, maiden flight of new Russian heavy lift vehicle of Angara rocket family is scheduled at 8:57 (GMT+3). No live stream will be provided from the launch site at Plesetsk cosmodrome. If flight will not be postponed, at about 9:07 Angara A5 will reach low Earth orbit. Briz-M upper stage then performed a series of 5 burns, to put the dummy payload on to GSO. Dummy payload is not planned to stay on GSO and will be put on to graveyard orbit by Briz-M.

Frome Wikipedia: "In the Angara A5, the four URM-1s used as boosters operate at full thrust for approximately 214 seconds, then separate. The URM-1 forming the vehicle's core is operated at full thrust for lift off, then throttled down to 30% to conserve propellant. The core is throttled back up after the boosters have separated and continues burning for another 110 seconds."

Pro tip: Check Wikipedia on everything to seem like a pro.

Didnt check the english wiki, no word of than in the german one...

Wow, 30% throttle. Not many engines can go that low...

Hmmm. Yeah RD-191. Good, versatile engine: can even do over nominal thrust (105 percent) as WELL as 8 degrees of gimbal! :0.0:

Always buy Russian (except for RS 25, that one I approve of)

What's the application for it? Everybody says there's no market to launch big things in space. I'm not very informed on this project.

Feeling proud, but the big launch tower and this expensive project make me also think of how lean Orbital Sciences are.

Capability is about the same as Proton. The application is covering the same payload ranges while launching from Russian sites such as Vostochny and Plesetsk-allowing Russia to wind down Baikonur and stop paying the Khazaks for the right to drop empty stages on them-and without using hypergolic propellants, which require expensive cleanup operations at stage impact sites.
