Cynicism is the easiest of all reactions, right? But it's also so disappointing and self-defeating.

The best simulator for spacewalking is underwater - it allows full visuals and body movement in 3D. Virtual reality is good, too, and has some advantages, like full Station simulation, not just part. Like all simulators, they have parts that are wrong and misleading: an important thing to remember when preparing for reality.
Interpretation
Training for spacewalking can be effectively done underwater and with virtual reality, but one must be aware of the limitations of these simulations.
Chris Hadfield emphasizes the importance of realistic training for astronauts, particularly for spacewalking, which can be best achieved through underwater simulations. He notes the advantages of virtual reality in providing comprehensive simulations but warns that both methods have their drawbacks. Understanding these limitations is essential for effective preparation for actual space missions.

Spacewalking trumps everything. Viscerally, it is a phenomenal place to be; to be able to glance right and see the world, glance left and see the universe, and realise for a moment that you're holding on to your known existence with one hand. That's the thing.
The Nile, draining out into the Mediterranean. The bright lights of Cairo announce the opening of the north-flowing river’s delta, with Jerusalem’s answering high beams to the northeast. This 4,258 mile braid of human life, first navigated end-to-end in 2004, is visible in a single glance from space.
The world, when you look at it, it just can't be random. I mean, it's so different than the vast emptiness that is everything else, and even all the other planets we've seen, at least in our solar system, none of them even remotely resemble the precious life-giving nature of our own planet.
Life off Earth is in two important respects not at all unworldly: you can choose to focus on the surprises and pleasures, or the frustrations. And you can choose to appreciate the smallest scraps of experience, the everyday moments, or to value only the grandest, most stirring ones.
Our role is to develop techniques that allow us to provide emergency life-saving procedures to injured patients in an extreme, remote environment without the presence of a physician.
Q: What were you thinking when your colleagues were out there making cosmic history? A: I just kept reminding myself that every single component in this spacecraft was provided by the guy who submitted the cheapest tender.
We were staring at the origin of a piece of our own bodies inside this 375-million-year-old fish. We had a fish with a wrist.
The Earth is round, and is inhabited on all sides, is insignificantly small, and is borne through the stars.
Global warming isn't a prediction. It is happening.
Our observation of nature must be diligent, our reflection profound, and our experiments exact. We rarely see these three means combined; and for this reason, creative geniuses are not common.
The apex of mathematical achievement occurs when two or more fields which were thought to be entirely unrelated turn out to be closely intertwined. Mathematicians have never decided whether they should feel excited or upset by such events.
