The authorities seem bored of building presidential residences from the Baltic to Kamchatka? And now they have decided to invest another trillion in expensive new toys?
-----------
But, yes, the Mars mission was a good idea. But if they wanted to go straight to interstellar - to Alpha Centauri. That's where there's a lot of money to be made...
There is no talk of honesty, we have to wait another 50 years.
Can you imagine a scenario for the next decades in which 50 years from now it will be fine ?
PhobosGrunt was doomed from the start, as were many other 'interplanetary vehicles'.
There are two problems: firstly, radio communication is used to control the vehicle, and secondly, when the vehicle enters the gravitational sphere of Mars, its velocity relative to the Earth observer changes abruptly. This jump in linear relative velocity results in a Doppler shift in the carrier frequency of radio communication, which is already hampered by the gigantic distances involved. Roughly the same thing happens when a vehicle moves from the Earth's gravitational sphere to the solar sphere, but in this case the distance is still short and so is the delay in signal transmission.
It is not possible to use broadband transceivers in which the frequency shift delta would fall within the bandwidth of the oscillating circuits, again because of the large distances and the transmitter power required for such broadband communication. (on Earth, whatever, but for every gram of vehicle...).
Until "scientists" realize that the boundary of the sphere of attraction of celestial bodies is sharp, vehicles will disappear one after another.
As long as "scientists" do not understand why the solar system, the asteroid belt, Saturn's rings, our galaxy, in the end - all have the shape of a disk and not a sphere, they will keep trying to "fly" with jet propulsion.
haw, I've said it all... ))

Don't be fooled, with ..... money from the space programme, just say so.
Do you have any? Money?
By the way, your beautiful arguments about the connection strangely work only against the Russians. Americans have made sixteen missions to Mars in recent years, only one or two have failed. And all sorts of Voyagers and Copernicus have been flying for decades and communicating from the outskirts of the solar system.
Not anymore. The witness is about to be drowned.

And they are specially trained on courses how to tell us pseudo-scientific nonsense.
And this one is training on us here.
Not anymore. Sawed off, the witness is about to be drowned.
Pity, I'm sure we'll miss you...
