or... maybe there's so much volume at the top of washing machines (above the water, where the controls are) that you could place the board there, where chips:
- don't need waterproofing
- don't need to be tightly integrated
- can be fully COTS since the logic is relatively dead simple
I've had 2 washing machines die in as many years, and the electronics were encased in silicone.
Of course, a repair involves replacing the entire proprietary electronics assembly (multiple PCBs, and plastic frame), and is just not economical, so the entire machine, valves, motor, steel drum and cabinet, are written-off because a mosfet failed, or whatever.
If the electronics were standardized and modular, even if encased in silicone, there would be an economic case to replace just failed modules.
It's basically assured that Anna will fly before Anil. Anil's got to do 2 years of astronaut candidate training, then become an astronaut and wait for a flight slot.
Remember the epic "Navy Seal + Harvard Doctor + Astronaut" guy still hasn't flown.
man, until you said that, it wasn't something i had noticed, and I was staring straight at it with full attention. I can't imagine someone driving for hours picking that up. After all it could an obstruction in the median.
Unfortunately, even if we do develop the capability to get astronauts out there, the Webb is constructed with a lot of adhesive and layered components and is basically impossible to service in space.
I think the best we could hope for is maybe being able to drill into the liquid helium tank and refill it - which is the ultimate determinate of its useful lifetime (that and propellant, but I'm led to believe the liquid helium will run out first).
Probably a moot point though: by the time we can get people out to do such an operation, I suspect a reduction in launch costs might lead to a much cheaper space telescope you could just drop off instead.
There is no consumable liquid helium. Past space telescopes have used consumable coolant, but JWST has a closed refrigeration system to cool the one instrument that requires active cooling.
If all goes as planned, the limiting factor is propellant. And the propellant tanks have the ports for on-orbit refueling, in case there is ever a desire to develop a robotic servicing mission for the task.
I mean, for a company eagerly (and correctly) removing the headphone jack for phones, it's the least surprising thing to remove GPU options. All that's left is RAM and HDD.
I briefly tried to use that. The Lightning port is centered in the case, so it's impossible to use the device in landscape without your hand knocking the connector loose. No, it doesn't work.
