OTA updates of the software are a hard requirement if your equipment is at 30 light minutes.
Actually, I remember reading somewhere that more and more they use FPGA chips, allowing to even "change out the CPU" if needed.

- j4mie 5y agoIs it still called OTA if there isn't any air?
- wereHamster 5y agoThere is air for the fist and last few dozens of kilometers (at varying density)
- samsari 5y agoOver the Aether?
- hvidgaard 5y agoThat isn't there either.

- hvidgaard 5y agoI am aware of the theory of quantum vacuum, but I generally take Aether to mean the old proposal as the medium light waves travel through. It has been refuted.
- codeulike 5y agoI think it can justifiably have a grander name than OTA. Lets call it an "OPA" - Other Planet Update Or perhaps "USTLLTFMMA" (updating software thats literally like thirty fucking million miles away)
- Trufa 5y agoAir doesn't have a strict definition right?
- TchoBeer 5y agoThere's very clearly air, seeing as the helicopter is flying.
- snypher 5y agoOver-the-antenna maybe, easier than a JTAG cable.
