> Can’t we use some other medium with more space?
> The conditions in space prove hostile to many data mediums. Traditional CDs or DVDs would be destroyed in space, because they are composed of layers and would come undone. It’s different with a medium made of ceramics. Also, you have to consider the dimensions and weight of your medium. The ceramic disc is light enough and resilient.
I'm guessing microSD cards are not radiation hardened.
- tracker1 10y agoWonder how much lead you'd have to wrap an sd card & reader in for it to be "safe" for space travel.
- dzdt 10y agoIf you want as much protection as Earth's atmosphere provides, 25 inches. At least that gives as much mass in between the card and space as the atmosphere does. (1 atm is about 30in of mercury, lead is 11/13 as dense as mercury...)
- tracker1 10y agoBut it isn't just about mass, there's density to consider... we aren't sending up computing devices into space wrapped in 25 inches of lead... so I'm guessing that far less is actually needed.
