Just to bring RN's info up to date
Virtually no data is returned to Earth directly to DSN at this stage in the mission - it's all relayed via Odyssey and then on to the DSN from there. The morning uplink containing one or more sols worth of instructions are uploaded, from the DSN to the rovers High Gain Antenna. Once the rover has recieved this, and transitioned to the new command sequence - it will 'beep' the low gain antenna for 10 minutes. Downlink is almost all conductied via one or more Mars Odyssey UHF relay passes in the afternoon. The current problem as I understand it is that there is something of a bottleneck when it comes to uplinking to Mars, and thus one either has to upload several sols of commands when the chance exists ( multiple restricted sols ) and/or use the UHF relay passes to uplink data to the rovers, which has quite a long lead time ( several hours ). Doug (oops - edited to make it a bit more obvious what I meant w.r.t DTE vs UHF) |
