I don't know. I didn't find the landing of the dragon into the ocean that exciting. Maybe its just me. I'll wait until they have landing boosters before I can get really excited. But falling into the ocean, its just so old and archaic!
Trunk sep was AFTER the re-entry engine burn, so it reentered at the same time as Dragon.
I bet it's a ribbon printer, the thought of a leaky ink cartridge in space.....
QuoteI bet it's a ribbon printer, the thought of a leaky ink cartridge in space..... Would an injet using liquid ink actually work in micro gravity? I suspect it needs gravity to feed the nozzles.Keith
here are three main technologies (HP, Epson and Canon). One has a jet that strikes the paper directly (HP), the other uses magnetic ink that's deviated and reused magnetically, but then it's let go when it has to print (Epson) and the third uses a bubble that's heated and sort of burst to send the ink (Canon). It would seem that the Epson process would be the most applicable to microgravity, since it's based on magnets and not on gravity. Incidentally, you can make a device to capture air borne ink with magnetic polarity. Thus, I suspect that the Epson system is somehow enhanced with stray ink capture mechanism.

I believe that was a very old technology that never went anywhere.In many Epson printers the cartridges are pressurized, but I believe still rely on gravity to get the ink down to the pickup tube. I doubt any would work in microgravity.
The Epson should work "propel droplets" is the key. Only issue might be to change the gap from nozzles to paper with some form of cover so it doesn't spray into the atmosphere.

I especially liked the fact that their "recovery force" consisted of a commercial salvage barge, two rubber boats, and a NASA P-3 Orion. No aircraft carrier task force necessary.
However things might get a little more involved if and when there is crew coming back in the Dragon.
