Modern silicon design with mems sensors I suspect could do an awful lot with a gram.
Also, at this scale, not much can be done by hand, so you can make hundreds of them for not much more cost than doing one.
- bpfrh 2y agoDoesn't modern electronics require massive shielding? e.g. you would need too much shielding and would go over the 1 gram restriction.
- minitoar 2y agoIf you have enough of them you can just lose some fraction and still function.
- flaminHotSpeedo 2y agoAlso it may work out that a lighter, faster probe with a shorter service life could have a greater effective range, if the service life is less sensitive to weight changes than the speed is
- minitoar 2y agoRight, that’s a nice way of thinking about it.
- SoftTalker 2y agoAnd how do you get the data back from these probes? The voyagers have antennas that are close to 4 meters in diameter and ~25-watt radio transmitters. You aren't doing that in a gram, and you aren't powering that in a gram either.
- minitoar 2y agoJust go read the starshot proposal. They address all of these issues, some more convincingly than others but they have thought it out in great detail. In short, it’s a swarm of gram-scale probes and they work together to transmit.
