Deep space energy source.

Using nuclear technology to power deep space exploration is an obvious answer to the energy supply question. And it is, and has been, applied for some time now in deep space and on Mars rovers.
One problem with nuclear power is radiation both on instruments and humans in close proximity to the source.
In deep space this problem can be solved by letting the nuclear power generator float at some distance from the spacecraft while providing electrical power to the craft.
As we do here on Earth, a nuclear power source could be housed away from the operational site on Mars and the Moon.
And as a matter of interest, nuclear powered submarines from several nations are currently operating 6 months at a time under water, generating their own oxygen from sea water.

I have a hunch

Russian progress in the invasion of Ukraine is not going to plan. That is evident from negotiations between the warring parties as I write this piece. I have seen photos of burned out military vehicles and speculate that they are Russian. Back during the end days of WWII when Soviet armour invaded Germany from the east, Germans were issued with large numbers of shoulder mounted anti tank weapons to help slow down the onslaught: Strategically positioned, one man could take out a Soviet tank in short order. And that happened. Fast forward to Ukraine, shoulder mounted missile launchers are an order of magnitude more effective than in WWII with smart missiles actively seeking their targets over the course of their trajectory. Sitting inside a tank these days, is sort of like being a knight in shiny armour, in the face of a lead ball from a musket. The tank becomes your coffin.

Metaphysical speculation

. George Orwell (Eric Blair), the famous author of "Animal Farm" and "1984", among other works, used to work in the British Imperial Civil Service during his early years, as a policeman in Burma, as I recall. A statement he made in reflecting upon that time in his life, when a local person was executed for something he had done, has stuck with me: "A universe ceased to exist" Over the years, that statement has given me pause for reflection on many a time, especially following a car accident in 2011 when I was knocked out cold for about half an hour and took some time to realize where I was and what had happened. One way to 'look' at things is as follows: What we perceive, feel and understand is a product of our material bodily structure and the many forces acting upon same. 'The Universe' is an aggregate of the above and give us a sense of who and what we are within the grander scheme of things. Now, let's put ourselves into the shell

Smelly cities

Watching a video of Imperial Rome reminded me of an experience I had visiting Singapore in 1971. Staying overnight in a modern hotel on the outskirts of the downtown, I ventured into the heart of the old city where narrow cobblestone streets had an open sewer running down the middle. In fact, if you approached the downtown from downwind, you could smell it a mile away. Eventually you get used to it but the initial impact is quite powerful. And so it was in Imperial Rome, a city with some 1 million people, many of whom lived in poverty and squalor. A hive of activity and breeding ground for all manner of infectious diseases. On the other side of the ledger, I lived in the City of Baghdad in 1961 where dry heat day temperatures in the summer ranged between 40 and 50 degrees Celsius. It did not have open sewers (the water would likely have evaporated) but the smell was so different, and not unpleasant, that I experienced it in my dreams long after having returned to Norway.
