We were watching live and the control room went from completely excited to somber in about a one second period. Space is hard.

Did they have L/S-band telemetry right up until the last seconds?

[anotheryou]

not sure what these bands are but the simulation stopped getting live data quite a few seconds before planned touchdown.

[walrus01]

omnidirectional (or not very strongly directional like an aimed x band parabolic antenna), low data rate in bps and intentionally narrow channel size, used for spacecraft command/control/telemetry somewhere between 1200 MHz and 2000 MHz.
