Other people's fuckups are no excuse for your own
PD, you bitch and complain when they fail and now you bitch because they are not sending valuable cargo into space on test launches... make up your mind...
Are they allowed to be cautious for tests or not?
BTW I am learning to become a brain surgeon... I have watched at least a half dozen Youtube videos, so I am not a complete novice... who wants to volunteer their heads for me to crack open and have a go at fixing?
There are more brain surgeons on this planet than there are rocket scientists launching payloads in to space.
It is people like you trying to shut down any discussion that has the slightest hint of criticism of Russian officials that provide ammunition to the actual haters at the other end of the spectrum.
Not launching actual payloads means less stress and better testing, which is the core purpose of the launch.
Sure, they could offset some of the costs of the test by carrying a payload, but that would require payload insurance which adds to the costs... it is not like it is all profit.
Equally, launching actual payloads would require a specific launch trajectory at a specific time which might not be suitable from the launch location they are using... it is OK just to say launch a satellite and they can pay for everything but what satellite.... what orbit... what timing... what is the launch window to get it into the right orbital altitude at the right time...
It also interferes with the launch schedule because the payload has to meet requirements and weight distribution needs and arrive on time to be fitted into the rocket in time for launch... lots of extra bullshit that is not useful for testing.
Some payloads also have acceleration limits which might be problematic.
Space exploration is not going to be profitable for a very long time, they already get buy on a very modest budget... using every single opportunity to make money can lead to accidents and problems that add no value to the programme.
