Why were there no communications with Aniara?

Considering an average distance to Mars of 100Mio km’s and the approximated travel time of +23 days, we talk about a speed of ~110000 km/h which is not out-of-reach even with todays technologies. And by those technologies, I see no reason why communication would be impossible. Even with a new kind of propulsion that would cut-off communication when running, let’s keep in mind that the accident rendered propulsion offline. So, from a scientific standpoint, that situation is ridiculous. Also the fact, that Aniara obviously dumped all it’s (nuclear) fuel, so, how is life support, artificial gravity and all the shiny attractions powered instead? Solar panels? Ahh, no. And I think when humanity mastered artificial gravity, we may have developed the one or other reliable way of communication. But science aside, don’t you think a trip of so many people (by the size of the ship certainly a good ten-thousands) wouldn’t be properly supervised from either Mars or Earth? No communication would be necessary for them to understand that something went wrong. I’m sliding back to science when I assume, that a vessel of that size would maintain several back-up systems so that no single in-bus screw shouldn’t cause that much of a damage also not an entire stock of them:-)

Anyway, all this leaves room for a thought that this journey went the way it does by intention. Earth is devastated, and the way Mimarobe spoke about Mars in an enraged moment, it seems to me this is not a place worth living for either. If, with all the technology at their hand, a trip to Mars still takes 23 days, other solar systems seem far out of reach. Maybe this was an experiment? Why would a simple transport ship (even a luxury one) have alge plants for Oxygen supply, if I don’t think for the long run? Mima itself, what for on a trip of 23 days – as shown in the “First hour” there was pretty much no interest. A full-featured swimming pool on a space ship? What the f… - assuming capitalism is still our social order, I’m not sure that ever becomes standard.

However, obviously nobody from the crew seemed to be involved in that plan even though the inner circle came-up quick with the realization, this will become a long journey. Why? Because it’s now customary that humanity would do nothing the rescue a good ten-thousands of their fellows? A ship of that size is undetectable when off-heading? There is nothing Earth’s hangar has to offer that can catch-up to a dream-liner with no propulsion? Hard to believe.

Even today experiments are on the way to discover how people behave in the claustrophobia of a space ship or the certainly limited supplies available when taking on Mars. Extreme situation, extreme measures and considering Earth’s condition shown in the intro, humanities future is at stake. An here is a theory for the Spear – it’s quite likely to me, the Spear might have been detected already from Earth or Mars, this way understanding it’s extra-terrestial and Aniara was silently sent out for a first contact… far away enough from Earth to take measures, if this contact doesn’t go as expected. And finally, hopefully enough DNA material is sent to a distant future to leave a footprint in space.

What are you folks think about this?
