user90495: Noob question here. Is it possible to send bitcoin transactions using Blockstream Satellite node or is it used only for receiving blocks?

user138728: You can use Blockstream satellite as part of a system to conduct transactions, but it can't send transactions on its own.
You can create the entire process of sending and receiving transactions (running a node), without a personal internet connection, by combining the Blockstream satellite hardware to receive blocks, offline wifi for local transactions, and localized mesh networks or SMS for broadcasting.
Excellent breakdown of process here:

user24925: No, communication is unidirectional, you can only receive the data which is broadcast by the system. The satellites being used are TV relays, the uplink essentially being amplified and re-broadcast without any knowledge of the content.Transaction broadcast needs to happen by terrestrial services like a cellphone network, dialup modem, or just the regular internet.
