[General] A Letter From Mojave - A Rocket Flight Opportunity For Code - Project Prometheus of Masten Space Systems

[Ethan Chew]

I stand corrected.  There is a way provided for telemetry data:

And from the project manager, Scott Nietfeld (in response to being asked on
the packet forwarder on the rates and guarantees of real-time data):

I admit my understanding of the technology and the statements above is
limited, but I believe they are saying there is a way to what you are
speaking of, Jeff; to have onboard code report back altitude to the
freenode server on #makerslocal.
