In August 2017, we launched the first coverage areas for Blockstream Satellite to enable free and private access to Bitcoin blockchain data. Recently, we completed coverage for the Asia Pacific region, coming closer to worldwide coverage, and announced the Satellite API — a service that provides developers an API that can be used to pay via the Lightning Network to beam down private messages from the satellites.
We are Adam Back, Chris Cook, and the Satellite team. Ask us anything!

Update: We just launched the Satellite API Beta! You can now pay with testnet LN BTC to broadcast data for interesting and exciting new use cases! https://blockstream.com/2019/01/16/satellite_api_beta_live/
