"Space Pens" - of which this is one - are ballpoint pens with a high quality ball and pressurized ink supply.
The pressurized ink supply allows the pen to write in any position, as ink flow is no longer gravity dependent.
The high quality - very textured I think - ball will write through many common contaminants on a paper.
The problem with these pens in the past is that they were easily dropped and lost secondary to the sleek, but too slippery, 'lipstick tube' or 'bullet' design.
The 'Trekker' is a sensible cylinder, with a knurled plastic grip, and a neck lanyard.
With daily use in an operating suite, and weekend use in aircraft, I have not had one of these pens fail to write, nor I have I had it slip from my hand and vanish.
The friction fit which holds the pen to the lanyard holder does wear in time. I find that I get just over a year's use before it becomes too loose to be reliable. This is about the same as the ink supply lasts me, so I no longer bother buying replacement ink cartridges.
The 'carabiner' clip is a useless gimmick, adding only weight, bulk, and another failure point.
