Good riddance. The Yenisei rocket was a monument to waste.
It is not cancelled, it is not urgent so they are delaying it so new technology and materials and likely engines can be further developed to make it more modern and capable.
Angara is scalable... but not set in stone... over time they might develop a new base model with better performance with new fuels and motors they could use as the core and boosters on a new family of rockets.
Angara will not be able to deliver any meaningful payload beyond low Earth orbit so if Russia wants do accomplish anything in space they will need Yenisei
So just as well they have not cancelled Yenisei then...
can't they just develop an upsized Angara like the propsed A7?
They could take the modular design of the Angara rocket and add new larger more powerful rockets that can also be modular for heavier work...
Even most optimistic estimates for lunar mission with Angara-A5 say that it would require 3 separate launches with orbital assembly, it's a clustefuck
Why? The ISS took hundreds of launches to get all its bits up and together and it still has potential for bits to be added to it. Requiring multiple launches is not a problem.
Haven't you heard the term all your eggs in one basket?
As posted by Garry elsewhere, one can go to the Moon and Jupiter by assembling a spacecraft from modules in LEO.
The A5 can deliver over 25 tons to LEO. So five shots give you a spacecraft with 150 tons. That ain't too shabby.
And an important point... the enormous mass required for a Mars manned mission means assembly in earth orbit will be mandatory... there is no chance in hell that you could build a rocket big enough to launch a craft able to go to mars direct from the surface of the earth to mars and back.
Doing it on a mission to the moon is good practise for something that will become standard procedure...
And we see here the usual peanut gallery Dunning-Kruger effect. Building ginormous rockets to launch spacecraft
on inertial flights to Mars and beyond is obsolete given the development by Russia of viable
nuclear propulsion for interplanetary missions.
And nuclear propulsion in space will dramatically reduce the amount of fuel required for a manned mars mission but you still wont be going in one hop from one rocket... just not going to happen.
Because it triples number of things that can go wrong, makes planning of any mission a colossal pain in the ass, eats too much time and if you thing that is bad just imagine how hard anything beyond moon would be
It's halfassed solution born of technical shortcomings
The only critical launches are the last ones with the people... any other could be relaunched with backups for the material lost...
All this cancellations of heavy payload carriers is consequence of the biggest traitor of all ,
vladimir putin , that cut in half the russian space budget a couple years ago and remains that way.
Nothing has been cancelled. He says that it is delayed... he seems to think new technologies are maturing that could change its design significantly enough to make it worth delaying its design and production... perhaps he has better access to information about new propulsion and materials than we have... difficult to believe I know...
Manned missions or lunar colonization won't be able to happen with just a single spacecraft launched from earth.
Ideally you would want to send resources and materials to the location before you send people so you could perhaps have a solid base for them to live in when they get there and perhaps enough fuel to get home if they need to come right back (doubtful I know... there are lots of situations where even having the fuel to get back is not good enough anyway..)
Which would you prefer for deep space mission:
a) Small spacecraft made up of large number of small components
b) Large spacecraft made up of small number of large components
Well for Earth Orbit Space Station they went for a... if you take a big one piece space ship to Mars then you are going to have to take that big heavy ship all the way there and bring it all the way back... that is going to burn a lot of extra fuel to allow you to be a bigger target for micro meteorites and radiation...

I suppose the pictures and images of the Angara pad build progress are all Kremlin propaganda?
