Two items of news yesterday caught my attention.
Item 1
The Voyager 1 and 2 Space Probes are still going - although with reduced capability - 47 years on from launch. Over the years a number of incedents have occurred which has meant the probes have had to be re-tasked. Of course this requires communications to be working at a distance of over 15 billion miles from earth and increasing. A number of times communications has become garbled or lost but developments here on Earth have managed to re-stablish communication with the probes and allowed engineers to send instructions to re-task them. Keep in mind the distance and the fact that it takes over 23 hours for Voyager 1 to get the instructions and the same for Earth to receive data. Data rates I think started out at 115Kbps but have dropped as the distance increases.
Hats off to the engineers on that one and the probes are expected to last until their 50th anniversary.
Item 2
Smart Meters - something I've been skeptical about for years. Apparently there are about 62% of homes with smart meters of which about 10% are in dumb mode. The reason being they can't communicate a few miles back to the servers. The problem is now highlighted as being worst in the north of England and in Scotland.
The Voyager Probe Project cost just under $1B in the late 1970's (about £60B in 2024 terms) - obivously there are on going costs in maintaining the project -
The Smart Meter Project cost are estimated to be about £15B so far but the difference in capabilities is far less than the Voyager Project.
FWIW: I can't have a Smart Meter installed but I've just managed to get one installed at our Community Hall just 3 miles away. Guess what - it only works in dumb mode.
