Send a weather balloon, satellite or interplanetary space probe up and let it record all the data you like, but don't transmit it back to Earth because then you don't need the hardware for a transmitter or the need to trace it. Then, get it to jettison a memory stick containing the data. This navigates
back to Earth if necessary, parachutes down and uses GPS coordinates to find its target, then sprouts wings, flies to the required location, knocks on your window or door, flies in and docks with your PC's USB port.

"Snowmobile" is a special transfer mechanism used for large data-transfer jobs between proprietary data centres and "the cloud". It's a big ol'-truck-o'disks. [zen_tom, Sep 08 2019]

Back in the day of 8" and 5-1/4" floppy disks (before flash was a glimmer in an engineer's eye,) This used to be called "sneakernet." [link] |

So far as i know, the postal service does not operate from space reliably. |

Nor does it operate from the UK realiably! |

A major objection: memory sticks have mass; bits don't. [-] |
|
| |
[Goldbb], transmitters have mass too, and i would imagine this would add to the mass of the probe more than a memory stick would as well as adding the complication of an extra thing which could go wrong. Then there's the complication of finding the probe and picking up its signal. None of these things are necessary with a flying memory stick. |

It seems to me that once your incomunicado satellite or probe has plunged to the bottom of the ocean, burnt up in the atmosphere or got beyond the bow shock of the heliosphere, you might decide it would've been nice if you'd put one of these on it first before you spent all that time, effort and money on it.
OK, the situation is this: We're trying to find a way of taking photographs automatically in the stratosphere and getting them back without having to retrieve the camera. This is a possible though far-fetched brainstorming suggestion of mine as to how to do it. I'm now thinking a radio transmitter might be easier. |

Surprisingly, perhaps, the Americans did more or less
exactly this [link] for many years, back when analog
film cameras could capture and store far more data
than digital ones. |

So this "flying memory stick" accomplishes all of its navigation and propulsion to
get home by means of magic, and this magic has no (or negligible) mass or
volume? Also, the magic always works perfectly? If so, including one of these
things seems worthwhile. |
